Hazardous drinking in New Zealand sportspeople: level of sporting participation and drinking motives

Episodic Binge-like Ethanol Reduces Skeletal Muscle Strength Associated with Atrophy, Fibrosis, and Inflammation in Young Rats

Binge Drinking (BD) corresponds to episodes of ingestion of large amounts of ethanol in a short time, typically ≤2 h. BD occurs across all populations, but young and sports-related people are especially vulnerable. However, the short- and long-term effects of episodic BD on skeletal muscle function have been poorly explored. Young rats were randomized into two groups: control and episodic Binge-Like ethanol protocol (BEP) (ethanol 3 g/kg IP, 4 episodes of 2-days ON-2-days OFF paradigm). Muscle function was evaluated two weeks after the last BEP episode. We found that rats exposed to BEP presented decreased muscle strength and increased fatigability, compared with control animals. Furthermore, we observed that skeletal muscle from rats exposed to BEP presented muscle atrophy, evidenced by reduced fiber size and increased expression of atrophic genes. We also observed that BEP induced fibrotic and inflammation markers, accompanied by mislocalization of nNOSµ and high levels of protein nitration. Our findings suggest that episodic binge-like ethanol exposure alters contractile capacity and increases fatigue by mechanisms involving atrophy, fibrosis, and inflammation, which remain for at least two weeks after ethanol clearance. These pathological features are common to several neuromuscular diseases and might affect muscle performance and health in the long term.

The functional and molecular effects of problematic alcohol consumption on skeletal muscle: a focus on athletic performance

Background: Chronic alcohol misuse is associated with alcoholic myopathy, characterized by skeletal muscle weakness and atrophy. Moreover, there is evidence that sports-related people seem to exhibit a greater prevalence of problematic alcohol consumption, especially binge drinking (BD), which might not cause alcoholic myopathy but can negatively impact muscle function and amateur and professional athletic performance.Objective: To review the literature concerning the effects of alcohol consumption on skeletal muscle function and structure that can affect muscle performance.Methodology: We examined the currently available literature (PubMed, Google Scholars) to develop a narrative review summarizing the knowledge about the effects of alcohol on skeletal muscle function and exercise performance, obtained from studies in human beings and animal models for problematic alcohol consumption.Results: Exercise- and sport-based studies indicate that alcohol consumption can negatively affect muscle recovery after vigorous exercise, especially in men, while women seem less affected. Clinical studies and pre-clinical laboratory research have led to the knowledge of some of the mechanisms involved in alcohol-related muscle dysfunction, including an imbalance between anabolic and catabolic pathways, reduced regeneration, increased inflammation and fibrosis, and deficiencies in energetic balance and mitochondrial function. These pathological features can appear not only under chronic alcohol misuse but also in other alcohol consumption patterns.Conclusions: Most laboratory-based studies use chronic or acute alcohol exposure, while episodic BD, the most common drinking pattern in amateur and professional athletes, is underrepresented. Nevertheless, alcohol consumption negatively affects skeletal muscle health through different mechanisms, which collectively might contribute to reduced sports performance.

Exploring the Association between Alcohol Drinking and Physical Activity in Adolescence; Two-Year Prospective Study in Younger Adolescents from Bosnia and Herzegovina

Insufficient physical activity and alcohol consumption (AC) are important health-threatening behaviors in adolescence, but there are controversial findings regarding the association that may exist between AC and physical activity levels (PALs) at this age. This study aimed to prospectively examine the relationship that may exist between AC and PAL in younger adolescence, considering the potential confounding effect of sports participation. The participants (n = 669, 337 females) were adolescents from Bosnia and Herzegovina who were tested on two occasions, at baseline (14 years of age) and again at follow-up (16 years of age). The variables included AC (as indicated by the AUDIT questionnaire), sports participation, age, gender (predictors), and PAL (obtained by the PAQ-A questionnaire) criterion. The results indicated that PAL at baseline was higher in those adolescents (boys) with a higher AUDIT score, but this association was partially confounded by sports participation. Multinomial regression indicated a higher risk of a decline in PAL over the study course in adolescents with a higher AUDIT score at baseline (OR = 1.32, 95%CI: 1.11-1.54 for being in the high-risk group for a decline in PAL). The most probable explanation is likely found in the high drop-out from sports in the studied period and earlier initiation of AC in adolescents involved in sports. Public health and sports authorities should urgently act preventively and develop educational programs against alcohol drinking in youth athletes.

Alcohol Sponsorship and New Zealand Regional Rugby Unions: Crisis Point or Business as Usual?

Alcohol sponsorship of sport in New Zealand, especially rugby, has a long history, but in recent times government-resourced reviews together with public health agencies, activists, and academics have proposed a ban of alcohol sponsorship of sport to help reduce alcohol-related harm. Responses to a proposed ban from a number of diverse sectors, including the alcohol industry and sport organizations, have ranged from ambiguous to resistant. Yet, the conditions for implementing a ban are poorly understood and there has been no change to state-regulated sponsorship policy to date. These widely publicized debates serve as a hotbed for discussions with provincial rugby union managers to consider the economic risks as well as the social connections between rugby clubs and cultural and civic life. In this paper, we address important new questions that query how the alcohol sponsorship debate plays out at a micro-level and the extent to which regional rugby unions may constitute a special case in terms of resistance to and the potential effects of regulation. The discussion expands the debate by drawing attention to the perceived positive effects of alcohol sponsorship as an enabler for addressing other social issues at a micro-level.

Relevance of Athlete-Specific Psychosocial Factors in High School Student-Athlete Alcohol Consumption

Background: Research suggests that adolescent student-athletes are at heightened risk for alcohol consumption. The identification of unique, modifiable risk factors for alcohol use in this population is needed. Purpose/Objectives: Building on previous work highlighting the importance of each of athlete-specific drinking motives and alcohol expectancies, this study investigated whether athlete-specific psychosocial predictors optimize our ability to predict adolescent athlete alcohol consumption after accounting for general psychosocial predictors. Methods: Participants were 352 current high school student-athletes who completed a self-report questionnaire about their alcohol use attitudes, behaviors, and cognitions. Results: Hierarchical regression revealed that among the total sample, gender, class year, liquid courage/sociability, sexuality, and negative alcohol expectancies, and negative athletic-functioning alcohol expectancies predicted alcohol consumption. Among lifetime drinkers, gender, class year, enhancement motives, conformity motives (negative), negative athlete-functioning alcohol expectancies, and sport-related coping motives predicted alcohol consumption. Conclusions/Importance: Negative athletic-functioning alcohol expectancies and sport-related coping motives emerged as important, athlete-specific predictors of adolescent athlete alcohol use. These factors provide important opportunities for targeted prevention efforts.

Influences of club connectedness among young adults in Western Australian community-based sports clubs

BACKGROUND

Along with physical benefits, community-based sport provides opportunities to enhance connectedness, an important protective factor of social and emotional health. However, young Australians participating in sport have been found to drink alcohol at higher levels than their non-sporting peers, and many clubs serve unhealthy food and beverages. This study explored the association between the dependent variable, level of alcohol consumption (AUDIT-C) and connectedness to club and other health behaviours among young people aged 18-30 years who play club sport in Western Australia.

METHODS

An online cross sectional survey measured levels of alcohol consumption (AUDIT-C), alcohol-related harm, connectedness (including volunteering and team cohesion), mental wellbeing, healthy food options and club sponsorship among young adults aged 18-30 years involved in sports clubs in Western Australia (n = 242). Relationships and association between the dependent variable (AUDIT-C) and independent variables were assessed.

RESULTS

Male sportspeople were more likely to drink alcohol at high-risk levels than females (p < .001), and respondents belonging to a club that received alcohol-related sponsorship were more likely to drink at high-risk levels (p = .019). Females were significantly more likely to want healthy food and beverage options provided at their clubs (p = 0.011). When all factors were considered team cohesion (p = 0.02), alcohol expectations (p = < .001), occurrences of experienced alcohol-related harm (p = <.001) and length of club membership (p = 0.18) were significant predictors of high-risk AUDIT-C (R2 = .34, adjusted R2 = .33, F (4, 156) = 20.43, p = <.001). High-risk AUDIT-C and club connectedness predicted strong team cohesion (R2 = .39, adjusted R2 = .39, F (2, 166) = 53.74, p = <.001).

CONCLUSIONS

Findings from this study may inform policy and practice to enhance healthy behaviours among young adults participating in community sports clubs in Australia and other countries.

Recreational and ergogenic substance use and substance use disorders in elite athletes: a narrative review

BACKGROUND

Substances from various classes may be used for recreational purposes, self-treatment or to boost performance. When substance use shifts from occasional to regular, heavy or hazardous use, positive and negative effects can develop that vary by substance class and athlete. Regular use of recreational or performance enhancing substances can lead to misuse, sanctions or use disorders.

OBJECTIVE

To review the prevalence, patterns of use, risk factors, performance effects and types of intervention for all classes of recreational and performance enhancing substances in elite athletes by sport, ethnicity, country and gender.

METHODS

A comprehensive search was conducted to identify studies that compared the prevalence and patterns of substance use, misuse and use disorders in elite athletes with those of non-athletes and provided detailed demographic and sport variations in reasons for use, risk factors and performance effects for each main substance class.

RESULTS

Alcohol, cannabis, tobacco (nicotine) and prescribed opioids and stimulants are the most commonly used substances in elite athletes, but generally used at lower rates than in non-athletes. In contrast, use/misuse rates for binge alcohol, oral tobacco, non-prescription opioids and anabolic-androgenic steroids are higher among athletes than non-athletes, especially in power and collision sports. Cannabis/cannabinoids seem to have replaced nicotine as the second most commonly used substance.

CONCLUSIONS

Substance use in elite athletes varies by country, ethnicity, gender, sport and competitive level. There are no studies on substance use disorder prevalence in elite male and female athletes and few studies with direct comparison groups.

Mental health in elite athletes: International Olympic Committee consensus statement (2019)

Mental health symptoms and disorders are common among elite athletes, may have sport related manifestations within this population and impair performance. Mental health cannot be separated from physical health, as evidenced by mental health symptoms and disorders increasing the risk of physical injury and delaying subsequent recovery. There are no evidence or consensus based guidelines for diagnosis and management of mental health symptoms and disorders in elite athletes. Diagnosis must differentiate character traits particular to elite athletes from psychosocial maladaptations.

Management strategies should address all contributors to mental health symptoms and consider biopsychosocial factors relevant to athletes to maximise benefit and minimise harm. Management must involve both treatment of affected individual athletes and optimising environments in which all elite athletes train and compete. To advance a more standardised, evidence based approach to mental health symptoms and disorders in elite athletes, an International Olympic Committee Consensus Work Group critically evaluated the current state of science and provided recommendations.

Taurine supplementation improves economy of movement in the cycle test independently of the detrimental effects of ethanol

Taurine (TA) ingestion has been touted as blunting the deleterious effects of ethanol (ET) ingestion on motor performance. This study investigated the effects of ingestion of 0.6 mL·kg^-1 of ET, 6 grams of TA, and ethanol in combination with taurine (ET+TA) on economy of movement (EM) and heart rate (HR). Nine volunteers, five female (22 ± 3 years) and four male (26 ± 5 years), participated in a study that used a counterbalanced experimental design. EM and HR were measured for 6 min while the subjects were pedalling at a fixed load 10% below the anaerobic threshold. The blood alcohol concentration (BAC) was similar between ET and ET+TA treatments at 30 min after ingestion and after exercise (12.3 mmol·L^-1 vs. 13.7 mmol·L^-1, and 9.7 mmol • L^-1 vs 10.9 mmol·L^-1, respectively). EM was significantly different among treatments, with lower mL·W^-1 following ingestion of TA (-7.1%, p<0.001) than placebo and ET+TA (-2.45%, p=0.001) compared to ET. HR (bpm) was significantly (p<0.05) higher for ET (137 ± 14 bpm) than the other three treatments (placebo = 129 ± 14 bpm; TA = 127 ± 11 bpm; TA+ET = 133 ± 12 and ET = 137 ± 14 bpm). Taurine improved EM when compared to placebo or ET, and reduced HR when compared to ET. The combination of ET+TA also enhanced EM compared to placebo, and reduced HR in comparison to ET alone. Therefore, these findings indicate that taurine improves EM and counteracts ethanol-induced increases in HR during submaximal exercise.

The Mental Health of Elite Athletes: A Narrative Systematic Review

Background

The physical impacts of elite sport participation have been well documented; however, there is comparatively less research on the mental health and psychological wellbeing of elite athletes.

Objective

This review appraises the evidence base regarding the mental health and wellbeing of elite-level athletes, including the incidence and/or nature of mental ill-health and substance use.

Methods

A systematic search of the PubMed, EMBASE, SPORTDiscus, PsycINFO, Cochrane and Google Scholar databases, up to and including May 2015, was conducted.

Results

The search yielded a total of 2279 records. Following double screening, 60 studies were included. The findings suggested that elite athletes experience a broadly comparable risk of high-prevalence mental disorders (i.e. anxiety, depression) relative to the general population. Evidence regarding other mental health domains (i.e. eating disorders, substance use, stress and coping) is less consistent. These results are prefaced, however, by the outcome of the quality assessment of the included studies, which demonstrated that relatively few studies (25 %) were well reported or methodologically rigorous. Furthermore, there is a lack of intervention-based research on this topic.

Conclusion

The evidence base regarding the mental health and wellbeing of elite athletes is limited by a paucity of high-quality, systematic studies. Nonetheless, the research demonstrates that this population is vulnerable to a range of mental health problems (including substance misuse), which may be related to both sporting factors (e.g. injury, overtraining and burnout) and non-sporting factors. More high-quality epidemiological and intervention studies are needed to inform optimal strategies to identify and respond to player mental health needs.

"That's cool, you're a musician and you drink": Exploring entertainers' accounts of their unique workplace relationship with alcohol

This qualitative research investigates the alcohol experiences of entertainers who perform within licensed premises. Previous, mainly quantitative, studies have found that entertainers, specifically musicians, are an occupational group who drink excessively. This qualitative study draws on a wider sample of entertainers to examine their accounts of drinking in the workplace and the explanations they provide for this. We conducted individual semi-structured interviews (n=24) with band-members, variety acts and DJs in Glasgow, Scotland. This revealed a workplace characterised by continual opportunities for often free alcohol consumption. Unlike most occupations, for entertainers 'drinking-on-the-job' was normative, expected, and sometimes encouraged by peers, the public, employers or sponsors. Entertainers also experienced performance-related incentives to drink before, during and/or after a show; including anxiety, matching their intoxication level to the audience's, and 'reward-drinking'. This qualitative research confirms the unique nature of the entertainer-alcohol link, even in comparison to that found within other leisure industry occupations. While providing some explanation as to why entertainers might drink excessively, participants' accounts also suggested potential strategies for avoiding the negative outcomes of workplace drinking.

Relationships Between Sport Participation, Problem Alcohol Use, and Violence: A Longitudinal Study of Young Adults in Australia

There is a growing body of evidence suggesting a link between sport participation and violent behavior outside of the sporting context. However, there have been few studies that have investigated the basis of this relationship. The current study examined longitudinal relationships between sport participation, problem alcohol use, and various violent behaviors, and whether sport participation moderates relationships between problem alcohol use and violence. The sample comprised 2,262 young adults (55% female, age range at Time 1 = 17-24 years) from Victoria, Australia, surveyed in 2010 and 2012. When controlling for common risk factors, substance use, and past violence, sport participation was not associated with any violent behaviors 2 years later. However, sport participation moderated the relationship between problem alcohol use and fighting, whereby problem alcohol use was associated with engaging in fights 2 years later for sport participants, but not for nonparticipants. These findings suggest that it is not sport participation per se that influences later violence but the drinking norms or culture embedded within certain sporting contexts. Prevention approaches that address the drinking culture and social approval of excessive alcohol consumption within sporting contexts may reduce the incidence of violent behavior in the community.

Interventions in sports settings to reduce risky alcohol consumption and alcohol-related harm: a systematic review

BACKGROUND

Elevated levels of risky alcohol consumption and alcohol-related harm have been reported for sportspeople and supporters compared to non-sporting populations. Limited systematic reviews have been conducted to assess the effect of interventions targeting such behaviours.

METHODS

A review was undertaken to determine if interventions implemented in sports settings decreased alcohol consumption and related harms. Studies were included that implemented interventions within sports settings; measured alcohol consumption or alcohol-related injury or violence and were either randomised controlled trials, staggered enrollment trials, stepped-wedged trials, quasi-randomised trials, quasi-experimental trials or natural experiments. Studies without a parallel comparison group were excluded. Studies from both published and grey literature were included. Two authors independently screened potential studies against the eligibility criteria, and two authors independently extracted data from included studies and assessed risk of bias. The results of included studies were synthesised narratively.

RESULTS

The title and abstract of 6382 papers and the full text of 45 of these papers were screened for eligibility. Three studies met the inclusion criteria for the review. One of the included studies was a randomised controlled trial (RCT) of a cognitive-behavioural intervention with athletes within an Olympic training facility in the USA. The study reported a significant change in alcohol use between pre-test and follow-up between intervention and control groups. The other two studies were RCTs in community sports clubs in Ireland and Australia. The Australian study found a significant intervention effect for both risky alcohol consumption at sports clubs and overall risk of alcohol-related harm. The Irish study found no significant intervention effect.

CONCLUSIONS

A limited number of studies have been conducted to assess the effect of interventions implemented in sports settings on alcohol consumption and related harms. While two of the three studies found significant intervention effects, it is difficult to determine the extent to which such effects are generalisable. Further controlled trials are required in this setting.

Ethanol does not delay muscle recovery but decreases testosterone/cortisol ratio

PURPOSE

This study investigated the effects of ethanol consumption on recovery from traditional resistance exercise in recreationally trained individuals.

METHODS

Nine recreationally trained volunteers (eight males and one female, 26 ± 4 yr, 81 ± 4 kg) conducted four resistance exercise sessions and consumed a low (0.6 (females) and 0.7 (males) g · kg(-1) body mass) or a high dose (1.2 or 1.4 g · kg(-1) body mass) of ethanol 1-2.5 h after exercise on two occasions. The first session was for familiarization with the tests and exercises and was performed without ethanol consumption. As a control trial, alcohol-free drinks were consumed after the exercise session. The sequence of trials, with low and high ethanol doses and alcohol-free drinks (control), was randomized. Maximal voluntary contractions (MVC) (knee extension), electrically stimulated contractions (knee extension), squat jumps, and hand grip strength were assessed 10-15 min and 12 and 24 h after the ethanol/placebo drinks. In addition to a baseline sample, blood was collected 1, 12, and 24 h after the ethanol/placebo drinks. The exercise session comprised 4 × 8 repetition maximum of squats, leg presses, and knee extensions.

RESULTS

MVC were reduced by 13%-15% immediately after the exercise sessions (P < 0.01). MVC, electrically stimulated force, and squat jump performance were recovered 24 h after ethanol drinks. MVC was not fully recovered at 24 h in the control trial. Compared with those in the control, cortisol increased and the free testosterone/cortisol ratio were reduced after the high ethanol dose (P < 0.01).

CONCLUSIONS

Neither a low nor a high dose of ethanol adversely affected recovery of muscle function after resistance exercise in recreationally strength-trained individuals. However, the increased cortisol levels and reduced testosterone/cortisol ratio after the high ethanol dose could translate into long-term negative effects.

Resiliency as a factor protecting youths from risky behaviour: Moderating effects of gender and sport

We hypothesised that resiliency may protect adolescents against risky behaviours, and that both the practicing of sports, and gender are moderating variables in relationships between resiliency and risky behaviours. The study included 18-year-old pupils from a selection of secondary schools (n = 556). A total of 188 individuals practiced competitive sports and the remaining 368 participants were non-athletes. The participants were examined with the Resiliency Assessment Scale for Children and Adolescents (SPP-18) and with a survey containing questions and statements related to high-risk "experiments with adulthood". Adolescent athletes showed higher levels of resiliency than their peers. The power of the "Determination and Persistence in Action" effect on "Alcohol" scale differed significantly between male athletes and male non-athletes. Only in the athletes groups were higher scores on this scale reflected by lower values on the "Drugs" scale. Moreover, it is possible to observe differences in undertaking risky behaviour between male and female athletes. The analysis of risky sexual behaviour suggests that sport is a risk factor for men, and a protective factor for women. These data suggest that consistent prophylactic and psycho-educative activities, with a special attention to differences between genders, should be provided to all the adolescents, irrespective of their sport performance levels.

Improving the implementation of responsible alcohol management practices by community sporting clubs: A randomised controlled trial

INTRODUCTION AND AIMS

Despite an increased prevalence of risky alcohol consumption and alcohol-related harm among members of sporting groups and at sporting venues, sporting clubs frequently fail to implement alcohol management practices consistent with liquor legislation and best practice guidelines. The aim of this study was to assess the impact of a multi-strategy intervention in improving the implementation of responsible alcohol management practices by sports clubs.

DESIGN AND METHODS

A randomised controlled trial was conducted with 87 football clubs, with half randomised to receive a multi-strategy intervention to support clubs to implement responsible alcohol management practices. The 2-year intervention, which was based on implementation and capacity building theory and frameworks, included project officer support, funding, accreditation rewards, printed resources, observational audit feedback, newsletters, training and support from state sporting organisations. Interviews were undertaken with club presidents at baseline and post-intervention to assess alcohol management practice implementation.

RESULTS

Post-intervention, 88% of intervention clubs reported implementing '13 or more' of 16 responsible alcohol management practices, which was significantly greater than the proportion of control groups reporting this level of implementation (65%) [odds ratio: 3.7 (95% confidence interval: 1.1-13.2); P = 0.04]. All intervention components were considered highly useful and three-quarters or more of clubs rated the amount of implementation support to be sufficient.

DISCUSSION AND CONCLUSIONS

The multi-strategy intervention was successful in improving alcohol management practices in community sports clubs. Further research is required to better understand implementation barriers and to assess the long-term sustainability of the change in club alcohol management practices.

Take One for the Team? Influence of Team and Individual Sport Participation on High School Athlete Substance Use Patterns

The current web-based survey investigated the association between team or individual sport participation (or both) and self-reported alcohol and tobacco use among high school athletes (N=1, 275) transitioning to college. Peak Blood Alcohol Concentration, weekly drinking, and alcohol-related problems were significantly lower among athletes in individual sports compared to other groups. Athletes competing in both team and individual sports reported greater lifetime tobacco use and combined alcohol/tobacco use compared to individual or team sports alone. Preventive strategies targeting HS athletes in general and those participating in team sports in particular may be useful in minimizing future alcohol use and related problems.

Associations of physical activity and sport and exercise with at-risk substance use in young men: a longitudinal study

OBJECTIVE

This study aims to measure the associations of physical activity and one of its components, sport and exercise, with at-risk substance use in a population of young men.

METHOD

Baseline (2010-2012) and follow-up (2012-2013) data of 4748 young Swiss men from the Cohort Study on Substance Use Risk Factors (C-SURF) were used. Cross-sectional and prospective associations between at-risk substance use and both sport and exercise and physical activities were measured using Chi-squared tests and logistic regression models adjusting for covariates.

RESULTS

At baseline, logistic regression indicated that sport and exercise is negatively associated with at-risk use of cigarettes and cannabis. A positive association was obtained between physical activity and at-risk alcohol use. At baseline, sport and exercise was negatively associated with at-risk use of cigarettes and cannabis at follow-up. Adjusted for sport and exercise, physical activity was positively associated with at-risk use of cigarettes and cannabis.

CONCLUSION

Sport and exercise is cross-sectionally and longitudinally associated with a low prevalence of at-risk use of cigarettes and cannabis. This protective effect was not observed for physical activity broadly defined. Taking a substance use prevention perspective, the promotion of sport and exercise among young adults should be encouraged.

Alcohol ingestion impairs maximal post-exercise rates of myofibrillar protein synthesis following a single bout of concurrent training

Introduction

The culture in many team sports involves consumption of large amounts of alcohol after training/competition. The effect of such a practice on recovery processes underlying protein turnover in human skeletal muscle are unknown. We determined the effect of alcohol intake on rates of myofibrillar protein synthesis (MPS) following strenuous exercise with carbohydrate (CHO) or protein ingestion.

Methods

In a randomized cross-over design, 8 physically active males completed three experimental trials comprising resistance exercise (8×5 reps leg extension, 80% 1 repetition maximum) followed by continuous (30 min, 63% peak power output (PPO)) and high intensity interval (10×30 s, 110% PPO) cycling. Immediately, and 4 h post-exercise, subjects consumed either 500 mL of whey protein (25 g; PRO), alcohol (1.5 g·kg body mass⁻¹, 12±2 standard drinks) co-ingested with protein (ALC-PRO), or an energy-matched quantity of carbohydrate also with alcohol (25 g maltodextrin; ALC-CHO). Subjects also consumed a CHO meal (1.5 g CHO·kg body mass⁻¹) 2 h post-exercise. Muscle biopsies were taken at rest, 2 and 8 h post-exercise.

Results

Blood alcohol concentration was elevated above baseline with ALC-CHO and ALC-PRO throughout recovery (P<0.05). Phosphorylation of mTOR^Ser2448 2 h after exercise was higher with PRO compared to ALC-PRO and ALC-CHO (P<0.05), while p70S6K phosphorylation was higher 2 h post-exercise with ALC-PRO and PRO compared to ALC-CHO (P<0.05). Rates of MPS increased above rest for all conditions (∼29–109%, P<0.05). However, compared to PRO, there was a hierarchical reduction in MPS with ALC-PRO (24%, P<0.05) and with ALC-CHO (37%, P<0.05).

Conclusion

We provide novel data demonstrating that alcohol consumption reduces rates of MPS following a bout of concurrent exercise, even when co-ingested with protein. We conclude that alcohol ingestion suppresses the anabolic response in skeletal muscle and may therefore impair recovery and adaptation to training and/or subsequent performance.

Alcohol consumption and sport: a cross-sectional study of alcohol management practices associated with at-risk alcohol consumption at community football clubs

BACKGROUND

Excessive alcohol consumption is responsible for considerable harm from chronic disease and injury. Within most developed countries, members of sporting clubs participate in at-risk alcohol consumption at levels above that of communities generally. There has been limited research investigating the predictors of at-risk alcohol consumption in sporting settings, particularly at the non-elite level. The purpose of this study was to examine the association between the alcohol management practices and characteristics of community football clubs and at-risk alcohol consumption by club members.

METHODS

A cross sectional survey of community football club management representatives and members was conducted. Logistic regression analysis (adjusting for clustering by club) was used to determine the association between the alcohol management practices (including alcohol management policy, alcohol-related sponsorship, availability of low- and non-alcoholic drinks, and alcohol-related promotions, awards and prizes) and characteristics (football code, size and location) of sporting clubs and at-risk alcohol consumption by club members.

RESULTS

Members of clubs that served alcohol to intoxicated people [OR: 2.23 (95% CI: 1.26-3.93)], conducted 'happy hour' promotions [OR: 2.84 (95% CI: 1.84-4.38)] or provided alcohol-only awards and prizes [OR: 1.80 (95% CI: 1.16-2.80)] were at significantly greater odds of consuming alcohol at risky levels than members of clubs that did not have such alcohol management practices. At-risk alcohol consumption was also more likely among members of clubs with less than 150 players compared with larger clubs [OR:1.45 (95% CI: 1.02-2.05)] and amongst members of particular football codes.

CONCLUSIONS

The findings of this study suggest a need and opportunity for the implementation of alcohol harm reduction strategies targeting specific alcohol management practices at community football clubs.

A qualitative study of the perceived impact of a community mobilisation intervention to reduce alcohol consumption among amateur sportsmen

Aim The aim of this study was to examine the perceived impact of a community mobilisation intervention programme to reduce alcohol consumption among amateur sportsmen aged 16-34 years.

METHOD

A qualitative focus group format was used to identify potentially important themes or concepts relating to players' and coaches' experiences of the intervention. Six focus groups were conducted (five with four to seven players per focus group and one with six coaches) to elicit participants' experiences of the intervention.

RESULTS

Three major themes emerged from the analyses: patterns of alcohol consumption and associated factors; perceived impact of the intervention; and suggested changes to the community mobilisation intervention. Excessive binge drinking (i.e. the consumption of six or more standard drinks on any one occasion) was common among players. The perceived impact of the intervention programme among players was low; players and coaches believed that if future programmes were to succeed, a 'bottom-up' rather than a 'top-down' approach should be adopted.

CONCLUSIONS

The findings suggest that players perceived the community mobilisation programme to have had only limited success in changing attitudes or behaviour towards alcohol consumption in this amateur sports setting.

Alcohol industry sponsorship and alcohol-related harms in Australian university sportspeople/athletes

INTRODUCTION AND AIMS

Although there is evidence that alcohol sponsorship in sport is related to greater drinking, there is no empirical research on whether alcohol sponsorship is associated with alcohol-related harms. We examined whether there is an association between receipt of alcohol industry sponsorship, and attendance at alcohol sponsor's drinking establishments (e.g. bars), and alcohol-related aggression and antisocial behaviour in university students who play sport.

DESIGN AND METHODS

University sportspeople (n = 652) completed surveys (response rate >80%) assessing receipt of alcohol industry sponsorship, attendance at sponsor's establishments and confounders [i.e. age, gender, sport type, location and alcohol consumption measured by Alcohol Use Disorders Identification Test--alcohol consumption (AUDIT-C) scores]. Participants also completed measures assessing displays and receipt of aggressive and antisocial behaviours (e.g. assaults, unwanted sexual advance, vandalism).

RESULTS

Logistic regression models including confounders and reported attendance at alcohol sponsor's establishments showed that sportspeople receiving alcohol industry sponsorship were more likely to have been the victim of aggression (adjusted odds ratio 2.62, 95% confidence interval 1.22-5.64). Attending an alcohol sponsor's establishment was not associated with higher rates of other aggressive or antisocial behaviour. However, significant associations where found between AUDIT-C scores and having displayed and received aggression, and having damaged or had property damaged. Male sportspeople were more likely to have displayed and received aggressive and antisocial behaviour.

DISCUSSION AND CONCLUSIONS

Higher AUDIT-C scores, gender and receipt of alcohol industry sponsorship were associated with alcohol-related aggression/antisocial behaviours in university sportspeople. Sport administrators should consider action to reduce the harms associated with excessive alcohol consumption and alcohol industry sponsorship in sport.

Complex interaction of religiousness with other factors in relation to substance use and misuse among female athletes

Strength of religious faith (SRF) is rarely studied as a protective factor against substance use and misuse in sports. Herein, we studied the potential buffering effect of the complex socio-educational, sports, and religiousness factors in the protection against substance use and misuse, including cigarettes, analgesics, appetite suppressants, potential doping behavior, and binge drinking. The sample of subjects included 40 high-class female athletes (22-26 years of age). Using a strictly anonymous questionnaire, we investigated different social, educational, and sports factors (including SRF measured by the Santa Clara Strength of Religious Faith Questionnaire) in relation to substance use and misuse. Following the calculation of simple correlations, multiple regression analysis revealed that in combination with low sports experience, SRF has a significant buffering effect against binge alcohol drinking and consumption of appetite suppressants. The data are discussed in comparison with previous findings and theoretical background. Future studies should study the topic while observing samples of recreational and competitive athletes of both genders.

Is there a danger for myopia in anti-doping education? Comparative analysis of substance use and misuse in Olympic racket sports calls for a broader approach

Background

Racket sports are typically not associated with doping. Despite the common characteristics of being non-contact and mostly individual, racket sports differ in their physiological demands, which might be reflected in substance use and misuse (SUM). The aim of this study was to investigate SUM among Slovenian Olympic racket sport players in the context of educational, sociodemographic and sport-specific factors.

Methods

Elite athletes (N = 187; mean age = 22 ± 2.3; 64% male) representing one of the three racket sports, table tennis, badminton, and tennis, completed a paper-and-pencil questionnaire on substance use habits. Athletes in this sample had participated in at least one of the two most recent competitions at the highest national level and had no significant difference in competitive achievement or status within their sport.

Results

A significant proportion of athletes (46% for both sexes) reported using nutritional supplements. Between 10% and 24% of the studied males would use doping if the practice would help them achieve better results in competition and if it had no negative health consequences; a further 5% to 10% indicated potential doping behaviour regardless of potential health hazards. Females were generally less oriented toward SUM than their male counterparts with no significant differences between sports, except for badminton players. Substances that have no direct effect on sport performance (if timed carefully to avoid detrimental effects) are more commonly consumed (20% binge drink at least once a week and 18% report using opioids), whereas athletes avoid substances that can impair and threaten athletic achievement by decreasing physical capacities (e.g. cigarettes), violating anti-doping codes or potentially transgressing substance control laws (e.g. opiates and cannabinoids). Regarding doping issues, athletes' trust in their coaches and physicians is low.

Conclusion

SUM in sports spreads beyond doping-prone sports and drugs that enhance athletic performance. Current anti-doping education, focusing exclusively on rules and fair play, creates an increasingly widening gap between sports and the athletes' lives outside of sports. To avoid myopia, anti-doping programmes should adopt a holistic approach to prevent substance use in sports for the sake of the athletes' health as much as for the integrity of sports.

Substance use and misuse among 17- to 18-year-old Croatian adolescents: correlation with scholastic variables and sport factors

Substance use and misuse (SUM) and the relation to physical activity/exercise/athletic participation (sport factors) and scholastic achievement are rarely studied in Croatia. The aim of this study was: (1) to investigate the SUM habits in Croatian adolescents (17-18 years of age, 254 males, and 218 females), and (2) to study potential gender-specific interrelationships between scholastic and sport factors in relation to SUM. The testing was done using an extensive, anonymous, self-administered questionnaire that consisted of scholastic variables, sport factors, and SUM data. Descriptive statistics, counts, and proportions were calculated. Gender differences were established using the Kruskal-Wallis test. Gender-specific correlations within and between studied variables were established using the Spearman's correlation. The incidence of smoking habits and alcohol consumption among Croatian adolescents was alarming, and a serious intervention program should be developed to address this issue. Educational achievement was negatively related to SUM, with no gender-specific relationships. The data indicated some "protective" effects of the sport factors against SUM in boys, but a significant positive correlation between alcohol drinking and sport participation in girls was also noted.

A low dose of alcohol does not impact skeletal muscle performance after exercise-induced muscle damage

Moderate, acute alcohol consumption after eccentric exercise has been shown to magnify the muscular weakness that is typically associated with exercise-induced muscle damage (EIMD). As it is not known whether this effect is dose-dependent, the aim of this study was to investigate the effect of a low dose of alcohol on EIMD-related losses in muscular performance. Ten healthy males performed 300 maximal eccentric contractions of the quadriceps muscles of one leg on an isokinetic dynamometer. They then consumed either a beverage containing 0.5 g of alcohol per kg bodyweight (as vodka and orange juice) or an isocaloric, isovolumetric non-alcoholic beverage. At least 2 weeks later, they performed an equivalent bout of eccentric exercise on the contralateral leg after which they consumed the other beverage. Measurement of peak and average peak isokinetic (concentric and eccentric) and isometric torque produced by the quadriceps was made before and 36 and 60 h post-exercise. Significant decreases in all measures of muscular performance were observed over time under both conditions (all P < 0.05); however, no difference between treatments was evident at any of the measured time points (all P > 0.05). Therefore, consumption of a low dose of alcohol after damaging exercise appears to have no effect on the loss of force associated with strenuous eccentric exercise.

Substance use and misuse among professional ballet dancers

This study investigated substance use and misuse among 16 female and 9 male Croatian ballet professionals in 2008 using an original questionnaire. We analyzed social, personal, activity- and training-related, and educational factors, and criteria such as: binge alcohol drinking, cigarette smoking, appetite suppressant consumption, analgesic use, and actual and potential "doping" habits. Frequency tables and rank-order correlation were calculated. More than one third of the male dancers reported binge drinking, while 20% of the females smoked more than a box of cigarettes per day. Almost 25% of these dancers will use "doping" if it will ensure successful ballet performance, regardless of negative health consequences. In males, the risk of potential "doping" behavior increased with age. In females, education level was negatively related to cigarette smoking, but positively correlated to potential "doping" habits and behavior. In both genders, religiousness was the factor negatively related to the following: (1) potential "doping" behavior and (2) belief that "doping" exists in professional ballet. Results suggest that there is evident need for more specific medical and/or psychological services in professional ballet. The study's limitations are noted.

Relationship of high school and college sports participation with alcohol, tobacco, and illicit drug use: a review

This study provides an exhaustive review of 34 peer-reviewed quantitative data-based studies completed on high school and college sports involvement and drug use. The studies reviewed suggest that participation in sport is related to higher levels of alcohol consumption, but lower levels of both cigarette smoking and illegal drug use. Additional research is needed in this domain to further elucidate the relationship between these variables.

Elite athletes' perceptions of the effects of illicit drug use on athletic performance

OBJECTIVE

To investigate the perceived risks and benefits that elite athletes associate with illicit drugs and their beliefs concerning the effects of recreational drug use on athletic performance.

DESIGN

Self-administered survey.

PARTICIPANTS

Nine hundred seventy-four elite athletes (mean age, 23 years; range, 18-30 years) were recruited from 8 national sporting organizations in Australia and the Australian Institute of Sport.

INTERVENTIONS

Participants completed a self-administered survey that included questions exploring participants' perceptions regarding the effects of illicit drug use on physical performance.

SETTING

National sporting organization meetings or competitions.

MAIN OUTCOME MEASURES

The main outcome measure was risk perception on athletic performance associated with illicit drug use.

RESULTS

The majority of athletes believed that illicit drug use would impact negatively on athletic performance. The main perceived effects of illicit drugs on athletic performance were physical and mental functioning. A minority of athletes indicated that drug use would not impact on physical performance when taken during the off-season or in moderation.

CONCLUSIONS

The main risks perceived in association with illicit drug use were short-term consequences, such as physical and mental functioning, rather than long-term health consequences. The current findings may contribute to the development of harm reduction strategies that communicate drug-related consequences to elite athletes in an appropriate and effective manner.

Can we consider religiousness as a protective factor against doping behavior in sport?

Religiousness is rarely studied in relation to doping behaviors in sport. In this study, we sampled 27 weightlifting/powerlifting athletes from Bosnia and Herzegovina. Using the originally developed questionnaire and by means of Spearman's correlation, we interpreted data and discussed relationships between (a) social, religious, sport, and educational factors, and (b) substance use criteria, including cigarettes, alcohol, analgesics, nutritional supplementation, and doping behaviors. In conclusion, we found (1) that religiousness can be considered as a potential protective factor against doping, but also (2) that religious subjects tend to deny and underestimate the doping behaviors in their sport. Both of these findings should be extensively studied in future investigations.

Religiousness as a protective factor for substance use in dance sport

Although religiousness is found to be a significant protective factor in substance use, there is an evidential lack of studies of such in athletes. The aim of the study was to identify the predictive value of the religiousness and some social, educational, and sport factors on substance use in 43 sport dancers. An originally developed questionnaire for studying substance use and precipitation factors was applied. The Chi-square showed male dancers as more religious than females. Using the Spearman's correlation, religiousness was found to be a significant protective factor in cigarette smoking, sport nutritional supplementation, and the likelihood of doping. Data were interpreted emphasizing the previous findings from the literature.

Acute alcohol consumption aggravates the decline in muscle performance following strenuous eccentric exercise

This study investigated the effects of acute moderate alcohol intake on muscular performance during recovery from eccentric exercise-induced muscle damage. Eleven healthy males performed 300 maximal eccentric contractions of the quadriceps muscles of one leg on an isokinetic dynamometer. They then consumed a beverage containing 1g/kg bodyweight ethanol (as vodka and orange juice) (ALC). On another occasion they performed an equivalent bout of eccentric exercise on the contralateral leg after which they consumed an isocaloric quantity of orange juice (OJ). Measurement of maximal isokinetic (concentric and eccentric) and isometric torque produced across the knee, plasma creatine kinase (CK) concentrations and muscle soreness were made before and at 36 and 60h following each exercise bout. All measures of muscle performance were significantly reduced at 36 and 60h post-exercise compared to pre-exercise measures (all p<0.05). The greatest decreases in peak strength were observed at 36h with losses of 12%, 28% and 19% occurring for OJ isometric, concentric, and eccentric contractions, respectively. However, peak strength loss was significantly greater in ALC with the same performance measures decreasing by 34%, 40% and 34%, respectively. Post-exercise plasma creatine kinase activity and ratings of muscle soreness were not different between conditions (both p>0.05). These results indicate that consumption of even moderate amounts of alcohol following eccentric-based exercise magnifies the normally observed losses in dynamic and static strength. Therefore, to minimise exercise related losses in muscle function and expedite recovery, participants in sports involving eccentric muscle work should avoid alcohol-containing beverages in the post-event period.

Drinking by professional Australian Football League (AFL) players: prevalence and correlates of risk

OBJECTIVES

To examine self-reported patterns of alcohol consumption and experience of alcohol-related harms among professional Australian Football League (AFL) players.

DESIGN, SETTING AND PARTICIPANTS

Cross-sectional survey of player alcohol consumption and self-reported alcohol-related harms among members of all 16 professional AFL clubs. Data relating to the 2006 football year were collected between 25 July and 30 August 2006 at regular football training sessions using a self-administered structured questionnaire.

MAIN OUTCOME MEASURES

Risky/high-risk drinking for long- and short-term harm at different times of the year; Alcohol Use Disorders Identification Test (AUDIT) score.

RESULTS

582 AFL players completed the questionnaire (an 83% response rate). Alcohol consumption varied at different times of the year. During the playing season (approximately 22 weeks), the level of risky/high-risk consumption for long-term harm in AFL players (11/564 [2%]) was typically lower than in age-matched Australian men in the general population (15%). However, risky/high-risk consumption for long-term harm was higher in AFL players during the end-of-season period (approximately 2 weeks) (303/561 [54%]) and vacation period (6-8 weeks) (231/559 [41%]) than in age-matched Australian men. Risky/high-risk drinking for short-term harm on a monthly basis was frequent at all times of the year (eg, 395/560 [71%] in the pre-season period). The mean AUDIT score was 8.8 (95% CI, 8.4 to 9.1; range, 0 to 36). Reports of harmful effects of drinking and negative consequences, such as getting involved in a fight (physical or verbal) while drinking (146/556 [26%]), were common. Risky/high-risk consumption for short-term harm on a monthly basis was associated with a variety of player characteristics, such as usually drinking in public locations (odds ratio, 1.55 [95% CI, 1.02 to 2.35]). AUDIT score was associated with variables such as marital status, with married players scoring more than two points lower (95% CI, - 3.58 to - 0.58) than single players. Formal club rules on alcohol consumption had little effect on outcome measures.

CONCLUSIONS

Drinking among AFL players is intricately related to time of year. This seasonal drinking pattern requires the development of specific club and league strategies to minimise drinking-related harms to players.

Alcohol industry sponsorship and hazardous drinking among sportspeople

AIMS

To examine the nature and extent of alcohol industry sponsorship of sportspeople, and its association with drinking.

METHODS

A purposive sample of participants (n = 1279) from various sporting codes were asked whether they personally, their team, or club received free and/or discounted alcohol or funding from an alcohol industry body (e.g. pub, brewery, wholesaler); how much they received; and whether they felt they should drink their sponsor's product and/or at the sponsor's premises. Drinking behaviour was assessed with the Alcohol Use Disorders Identification Test (AUDIT) questionnaire.

FINDINGS

Alcohol industry sponsorship was reported by 47.8% of the sample. Of those sponsored, 47% reported receiving free and/or discounted alcohol products. In multivariate models, those receiving sponsorship at the individual, team and club level had AUDIT scores that were, on average, 2.4 points higher [95% confidence interval (CI): 0.70-4.09] than those who received no sponsorship. Receiving free and/or discounted alcohol (beta(adj) = 0.95, 95% CI: 0.01-1.88) and feeling that they should go to the sponsor's pub/club to drink (beta(adj) = 1.91, 95% CI: 0.85-2.98) were also associated with higher AUDIT scores. Provision of free or discounted alcoholic beverages was associated more strongly with AUDIT scores (beta(adj) = 1.56; 95% CI: 0.62-2.51) than other forms of sponsorship from the alcohol industry (e.g. provision of uniforms).

CONCLUSIONS

Alcohol industry sponsorship of sportspeople, and in particular the provision of free or discounted alcoholic beverages, is associated with hazardous drinking after adjustment for a range of potential confounders. Sports administration bodies should consider the health and ethical risks of accepting alcohol industry sponsorship.
