Female adolescent athletes' attitudes and perspectives on injury prevention programs

Developing injury prevention programmes for ladies Gaelic football: a Delphi study

BACKGROUND

High injury rates are evident in the community sport of ladies Gaelic football, and the costs associated with these injuries have major implications for players and the governing body. Injury prevention programmes have been designed but are not being widely adopted. This study aimed to elicit the expert opinion of academics and practitioners on the content and format of injury prevention programmes for ladies Gaelic football.

METHODS

Twenty-four experts from the areas of coaching science, injury prevention, athletic therapy and physiotherapy took part in this three-round Delphi study. Each round contained multiple-choice, Likert scale and open-ended questions. For each question, consensus was defined as 67% or greater agreement among experts.

RESULTS

The experts agreed that 17 components (eg, agility, balance) should be included in injury prevention programmes for ladies Gaelic football, with 12 considered vital for inclusion in most or every session. Programmes should require minimal/no equipment, be 10-15 min in duration and contain 3-4 versions of each exercise for progression and variation purposes. Experts recommended when certain components should be completed but generally agreed that programmes should be capable of being delivered throughout sessions. There was consensus among experts for 13 items (eg, pictures, exercise volume) to be included in full versions of programmes and six in condensed versions.

CONCLUSIONS

The outcomes of this study provide the foundation for the development of future injury prevention programmes for ladies Gaelic football. Combining these findings with the preferences of end-users throughout programme development may enhance the efficacy of future injury prevention programmes.

Anterior Cruciate Ligament Injury Prevention Programs in Welsh Netball: A Survey of Knowledge, Implementation and Barriers Amongst Players and Coaches

Background Anterior cruciate ligament (ACL) injury prevention programs can reduce injury risk in various sports. The perception of ACL injury prevention programs amongst professional netball players and coaches has not been studied. Purpose The aim of this study was to determine (1) the level of awareness and experience of ACL injury prevention programs, (2) the use of ACL injury prevention programs, and (3) barriers and potential facilitators to implementing a sustainable ACL injury prevention program in netball. Materials and methods Female netball players representing Welsh senior and under-21 teams and elite and amateur coaches were invited electronically to participate in this web-based cross-sectional observational study between 1st May and 31st July 2021. Information on ACL injury susceptibility and seriousness, knowledge, experience, and implementation of ACL injury prevention programs were ascertained. Results Twenty-eight players (78%) and 29 coaches (13%) completed the questionnaire. Seventeen (61%) players and 15 (52%) coaches reported that female athletes were at greater risk of sustaining ACL injuries. Over 90% of respondents identified netball as high-risk, whilst 89% (n=25) of players and 76% (n=22) of coaches reported these injuries to be preventable. Only two (7%) players and six (21%) coaches utilised an ACL injury prevention program with a lack of time and engagement from coaches and players identified. The majority of respondents indicated that their club has neither promoted, advocated the use nor demonstrated exercises for ACL injury prevention. Over 90% of respondents would utilise an ACL injury prevention program if it minimised players' risk with appropriate information and demonstration of exercises. Conclusion This study highlights limited knowledge of female athletes' increased susceptibility to ACL injuries amongst players and coaches with a lack of communication and education on ACL injury prevention programs between sporting associations, coaches, and players. However, the results demonstrate willingness amongst both players and coaches to implement an ACL injury prevention program in netball.

Gaelic games players' awareness and use of, and attitudes towards injury prevention exercise programmes

OBJECTIVE

The aim was to determine the awareness of and use of injury prevention exercise programmes (IPEPs) among adult Gaelic games players and to investigate Gaelic games players' attitudes to injury prevention and barriers and facilitators to successful IPEPs use.

METHODS

A recruitment email was sent to all clubs and county boards throughout Ireland (whose email was available online) and the survey was advertised on social media platforms. Adult players completed an anonymous survey, including awareness, use, and attitudes towards injury prevention and injuries. Frequencies and descriptive statistics were conducted, a chi-squared test was used to assess any differences in awareness and use of IPEPs, a Mann-Whitney U test was used to examine differences between groups for attitudes to injury prevention (men vs women; elite vs non-elite).

RESULTS

A third of players (32.4%) stated awareness of IPEPs. However, only 13.4% correctly identified one. A significantly greater number of men (35.7%) used IPEPs compared to women (26.5%) (p = 0.04). The Activate (65.5%) and GAA15 (32.5%) were most used. Players had a positive attitude towards injury prevention but agreed that injuries were an issue (68.2%) and stated that their coach didn't have enough knowledge how to use IPEPs was a large barrier (41.6%).

CONCLUSION

Despite this positive attitude to injury prevention and believing injuries are an issue, adoption remains low. Organisations/clubs should educate players on the benefits of using IPEPs and support structures put in place to gain greater implementation, which is critical to mitigating the risk of injury.

Development of a Cutting Technique Modification Training Program and Evaluation of its Effects on Movement Quality and Cutting Performance in Male Adolescent American Football Players

This study developed a cutting technique modification training program and investigated its effects on cutting performance and movement quality in adolescent American football players. For six weeks, an intervention group (IG) of 11 players participated in 25 min cutting technique modification training sessions integrated into team training twice a week, while a control group (CG) of 11 players continued their usual team training. Movement quality was assessed by evaluating 2D high-speed videos, obtained during preplanned 45° and 90° cutting tests, using the Cutting Movement Assessment Score (CMAS) qualitative screening tool. Cutting performance was assessed based on change of direction deficit (CODD). Significant interaction effects of time × group were found for CMAS in 45° and 90° cuttings (p < 0.001, ηp2 = 0.76, p < 0.001, ηp2 = 0.64, respectively), with large improvements in the IG (p < 0.001, g = -2.16, p < 0.001, g = -1.78, respectively) and deteriorations in the CG for 45° cuttings (p = 0.002, g = 1.15). However, no statistically significant differences in CODD were observed pre-to-post intervention. The cutting technique modification training was effective at improving movement quality without impairing cutting performance, and it can be used by practitioners working with adolescent athletes.

Field Hockey-Related Injuries Treated in US Emergency Departments, 2000 to 2020

OBJECTIVE

To describe the epidemiology of field hockey-related injuries of patients aged 6 to 24 years who were treated in US emergency departments from 2000 to 2020.

DESIGN

The researchers conducted a retrospective analysis using data from the National Electronic Injury Surveillance System (NEISS).

SETTING

The NEISS collects data on recreational activity-related and consumer product-related injuries treated in US Eds.

PATIENTS

Patients aged 6 to 24 years who were treated for field hockey-related injuries in Eds from 2000 to 2020.

INDEPENDENT VARIABLES

The researchers analyzed characteristics that included age, body part injured, injury diagnosis, disposition from the ED, injury locale, injury mechanism, contact, and equipment type.

MAIN OUTCOME MEASURES

All cases of field hockey-related injuries were identified using the NEISS product code for field hockey (1295).

RESULTS

There were an estimated 82 639 (95% CI = 45 536-119 742) field hockey-related injuries for patients aged 6 to 24 years treated in US emergency departments from 2000 to 2020. The rate of field hockey-related injuries per 100 000 population did not significantly change from 7.4 in 2000 to 7.4 in 2011 (slope = 0.048; P = 0.581) but significantly decreased from 7.4 in 2011 to 3.7 in 2019 (slope = -0.40; P = 0.018). As player age increased, the risk of injury due to contact with equipment increased ( 13 years: RR = 0.90; 95% CI = 0.82-0.98, 19-24 years: RR = 1.17; 95% CI = 1.06-1.29). Concussions or traumatic brain injuries accounted for 9.2% of injuries and were most associated with contact with the ball.

CONCLUSION

Although there was a decrease in the field hockey-related injuries, field hockey remains an important source of injuries for children and young adults.

Effects of pubertal growth variation on knee mechanics during walking in female and male adolescents

INTRODUCTION

Puberty substantially alters the body's mechanical properties, neuromuscular control, and sex differences therein, likely contributing to increased, sex-biased knee injury risk during adolescence. Female adolescents have higher risk for knee injuries than male adolescents of similar age engaging in similar physical activities, and much research has investigated sex differences in mechanical risk factors. However, few studies address the considerable variation in pubertal growth (timing, pace), knee mechanics, and injury susceptibility within sexes, or the impact of such growth variation on mechanical injury risk.

OBJECTIVES

The present study tested for effects of variation in pubertal growth on established mechanical knee injury risk factors, examining relationships between and within sexes.

METHODS

Pubertal growth indices describing variation in the timing and rate of pubertal growth were developed using principal component analysis and auxological data from serial stature measurements. Linear mixed models were applied to evaluate relationships between these indices and knee mechanics during walking in a sample of adolescents.

RESULTS

Later developing female adolescents with slower pubertal growth had higher extension moments throughout stance, whereas earlier developers had higher valgus knee angles and moments. In male adolescents, faster and later growth were related to higher extension moments throughout gait. In both sexes, faster growers had higher internal rotation moments at foot-strike.

CONCLUSIONS

Pubertal growth variation has important effects on mechanical knee injury risk in adolescence, affecting females and males differently. Earlier developing females exhibit greater injury risk via frontal plane factors, whereas later/faster developing males have elevated risk via sagittal plane mechanisms.

A qualitative examination of injury prevention strategy and education in Ladies Gaelic football: Understanding the preferences of players and coaches

The high rates of injury in Ladies Gaelic football impact the wellbeing of players and are a major financial burden for the Ladies Gaelic Football Association. Effective injury prevention programmes have been developed for Gaelic games, but these are not currently widely adopted. The aim of this study was to qualitatively investigate adult Ladies Gaelic football players and coaches' preferences for injury prevention strategies and injury prevention education using a constructivist grounded-theory approach. Semi-structured interviews were conducted with 23 currently active Ladies Gaelic football coaches and adult players. The core strategy preferences discussed by participants were the properties of an injury prevention programme, the role of stakeholders, strategy logistics and the need for guidance and support. If the uptake and long-term adoption of an injury prevention programme is to be maximised, the preferences of the players and coaches who will ultimately utilise the programme must be understood and integrated into a wider implementation strategy developed around their needs. For education preferences, the core categories identified were the focus of education, who needs education, the format, educator, roll-out strategy, and time required. Future educational strategies must incorporate the preferences of stakeholders into their design if they are to be successful in spreading injury prevention knowledge and achieving change. To give injury prevention strategies, programmes, and education the best chances at successful adoption, it is crucial that the preferences of end-users are addressed and implemented.

Barriers and facilitators to injury prevention in ladies Gaelic football: A qualitative study

OBJECTIVES

Injury rates have remained high in ladies Gaelic football over the last decade and treatment costs continue to increase significantly. Injury prevention programmes are a proposed solution and their efficacy has been demonstrated in Gaelic games, however, anecdotally their adoption is low. The aim of this study was to determine the barriers and facilitators to uptake, implementation, and long-term adoption of an injury prevention strategy for adult Ladies Gaelic football players and coaches.

DESIGN

Semi-structured interviews were conducted with 23 participants (13 coaches, 10 players). Four coaches were at intercounty level and nine were at club level, while two players competed at intercounty and club level and eight played solely at club level. The interviews were audio-recorded, transcribed verbatim and thematically analysed.

RESULTS

Stakeholder attitudes, accessibility, education, communication, and injury prevention programme characteristics were perceived as key barriers to an injury prevention strategy succeeding. Injury prevention promotion, injury prevention programme characteristics, leadership, and communication, were identified as the main factors that would facilitate the success of a strategy.

CONCLUSIONS

By utilising the views of stakeholders, the initial uptake, adherence, and long-term adoption of an injury prevention strategy in Ladies Gaelic football may be maximised.

Non-Time-Loss and Time-Loss Injuries in Secondary School Girls' Volleyball Athletes: A Report From the National Athletic Treatment, Injury, and Outcomes Network Surveillance Program

CONTEXT

Volleyball is a popular sport with a risk of injury to the entire body. Insight into non-time-loss (NTL) and time-loss (TL) injuries is needed to inform seasonal injury trends that may lead to appropriate prevention and management strategies. This study provides a descriptive analysis of volleyball injuries among secondary school athletes.

STUDY DESIGN

Descriptive epidemiology study.

METHODS

Data were collected from 72 secondary schools, representing 135 team seasons of data from the National Athletic Treatment, Injury, and Outcomes Network Surveillance Program (2014-2015 to 2018-2019 academic years). Injury counts, injury rates (IR) per 1000 athlete exposures (AEs), and incidence rate ratios (IRR) were reported with 95% confidence intervals (CIs).

RESULTS

In total, 529 injuries over 193,858 AEs for girls' volleyball were captured, producing an IR of 2.73/1000AEs (95% CI = 2.50-2.96). The overall IR was highest during the preseason compared with regular season (IRR = 1.31, 95% CI = 1.09-1.59). Overall IRs were higher in competition (IR: 3.56, 95% CI = 3.07-4.05) compared with practice (IR: 2.38, 95% CI = 2.12-2.64; IRR = 1.49, 95% CI = 1.25-1.79). Common body locations injured were ankle (n = 141, 26.7%; NTL: n = 56, 21.7%; TL: n = 85, 31.7%), knee (n = 61, 11.5%; NTL: n = 33, 12.8%, TL: n = 28, 10.5%), hand/wrist (n = 59, 11.2%; NTL: n = 32, 12.4%, TL: n = 27, 10.1%), and head/face (n = 62, 11.7%; NTL: n = 14, 5.4%; TL: n = 47, 17.5%).

CONCLUSIONS

Volleyball IRs were highest in preseason and during competition. Most injuries affected the lower-extremity which is notable considering the high upper-extremity load in volleyball. Consideration of strategies to reduce injuries prior to the start of the formal sports season may be needed to help reduce the incidence of preseason injuries.

Integrating neurocognitive challenges into injury prevention training: A clinical commentary

Despite the efforts of many traditional lower extremity injury prevention programs (IPP), the incidence of anterior cruciate ligament injuries in young athletes continues to rise. Current best practices for IPPs include training lower extremity neuromuscular control and movement quality during cutting, jumping, and pivoting. Emerging evidence indicates neurocognition may contribute to injury incidence and injury risk biomechanics. Therefore, IPP outcomes may improve if clinicians also consider neurocognitive contributions to neuromuscular control and athletic performance. A substantial barrier to neurocognitive challenge integration during injury prevention training in the group setting is the lack of structured neuromuscular and neurocognitive progressions. Therefore, our aim is to provide clinicians with a defined framework and recommendations from clinical experience for how to implement neurocognitive challenges within group IPPs that requires minimal extra time and resources. This clinical commentary proposes a three-phase model adopted from motor learning literature to simultaneously progress neuromuscular and neurocognitive challenges through a structured IPP.

Can we explain running-related injury preventive behavior? A path analysis

BACKGROUND

Behavioral and social science theories/models have been gaining attention in sports injury prevention.

OBJECTIVE

To investigate the potential of the Theory of Planned Behavior in explaining running-related injury preventive behavior.

METHODS

Six-month prospective cohort study based on data gathered from a randomized controlled trial. From a total of 1512 invited trail runners, 232 were included in this study. Preventive behaviors and their determinants were assessed at baseline and two and six months after baseline. Five-point Likert scales were used to assess the determinants of preventive behavior. A Bayesian path analysis was conducted applying mixed models and mediation analysis.

RESULTS

A 1-point increase in intention, attitude, subjective norm, and perceived behavioral control predicted an increase of 54% (95% Bayesian credible interval [BCI]: 38, 71) in the rate of performing running-related injury preventive behavior, explaining 49% (R² 0.49; 95% BCI: 0.41, 0.56) of the variance around preventive behavior. Intention and perceived behavioral control predicted running-related injury preventive behavior directly, while 40% (95% BCI: 21, 61) and 44% (95% BCI: 20, 69) of the total effect of attitude was mediated by intention and perceived behavioral control, respectively. Attitude, subjective norm, and perceived behavioral control predicted intention.

CONCLUSIONS

The Theory of Planned Behavior may have the potential to explain half of the variance around running-related injury preventive behavior and intention. Therefore, such theory may be considered a relevant and useful tool in developing, investigating, and/or implementing programs aimed at preventing running-related injuries.

The Protective Effect of Neuromuscular Training on the Medial Tibial Stress Syndrome in Youth Female Track-and-Field Athletes: A Clinical Trial and Cohort Study

CONTEXT

Few reports have analyzed the effects of neuromuscular (NM) training programs on the injury incidence among youth female track-and-field athletes.

OBJECTIVE

To determine the effects of NM training on reducing lower limb injury incidence and to establish its effects on countermovement jump performance, balance, 30-m sprint, and joint position sense in youth female track-and-field athletes.

DESIGN

Single-blind, randomized controlled clinical trial.

SETTING

Sports research laboratory.

PARTICIPANTS

Twenty-two female athletes were allocated into 2 groups: Conventional (CONV) training (n = 11; age = 15.3 [2.1] y) and NM training (n = 11; age = 15.0 [2.7] y).

INTERVENTIONS

Interventions were performed during the preseason of 6 weeks. The CONV training included anaerobic, strength, and aerobic training. The NM training consisted of a multicomponent program that integrated jumps, landings, and running with strength, endurance, agility, balance, and CORE training.

MAIN OUTCOME MEASURES

A follow-up of the cohorts was carried out through the evaluation of lower limb injuries (main outcome) during a regular season (weeks 7-18). Secondary outcomes were measured before and after the intervention: Y-balance test, active joint repositioning, ground reaction force, and countermovement jump height.

RESULTS

The injury incidence rate was 17.89 injuries per 1000 hours athlete-exposure in CONV training, and 6.58 in NM training (relative risk = 0.38; 95% confidence interval,  0.18 to 0.82; P = .044). Particularly, the medial tibial stress syndrome incidence rate was 5.96 injuries per 1000 hours athlete-exposure in CONV training and 0.82 in NM training (relative risk = 0.17; 95% confidence interval, 0.02 to 1.12; P = .012). In addition, a significant training × time interaction was noted, favoring improvements in 30-m sprint and countermovement jump height after NM.

CONCLUSION

The NM training may improve youth female athlete's physical fitness and reduce their injury relative risk of medial tibial stress syndrome injury.

Short and long versions of a 12-week netball specific neuromuscular warm-up improves landing technique in youth netballers

OBJECTIVE

To investigate the efficacy of two 'NetballSmart', netball specific warm-ups in improving landing technique measures in New Zealand secondary school netball players.

DESIGN

Multi-site cluster experimental trial.

PARTICIPANTS

77 youth participants, mean ± SD age = 15.8 ± 0.9 were recruited from secondary school netball teams.

SETTING

12 teams from 6 schools performed either the NetballSmart Dynamic Warm-up (NSDW) (n = 37); or Power warm-up (PWU) (n = 40), three times a week for 12 weeks. All players within a school (2 teams) were assigned the same warm-up, avoiding treatment contamination.

MAIN OUTCOME MEASURES

A series of unilateral and bilateral drop vertical jumps on to a portable force plate were completed by all participants. Measures included peak vertical ground reaction force (GRF) for single-leg and bilateral landings; frontal plane projection angle (FPPA) for right and left single-leg landings and Landing error scoring system (LESS) for bilateral landings. Paired t-tests were used to assess mean differences pre and post the warm-up. Generalised linear mixed effects models were developed to evaluate the effects between the NSDW and PWU groups.

RESULTS

Significant improvements were found in all the landing technique outcome measures for both warm-up groups (ES Range- GRF = -0.6 to -1.1; FPPA = 0.8 to 1.2; LESS = -1.6 to-3.2; p < 0.05). Results of mixed effects models revealed that there was only a significantly greater improvement in LESS for the PWU group (β = -0.30, p = 0.001).

CONCLUSION

Results show both warm-ups can improve landing technique measures in youth secondary school netball players. It is recommended that coaches should consider implementing one of the two warm-ups in their netball programmes. Their choice of warm-up will likely be dependent on their environment and time demands.

Use of Social or Behavioral Theories in Exercise-Related Injury Prevention Program Research: A Systematic Review

BACKGROUND

The use of social or behavioral theories within exercise-related injury prevention program (ERIPP) research may lead to a better understanding of why adherence to the programs is low and inform the development of interventions to improve program adherence. There is a need to determine which theories have been used within the literature and at what level theory was used to further the field.

OBJECTIVE

To determine which social or behavioral science theories have been incorporated within ERIPP research and assess the level at which the theories were used. The key question guiding the search was "What social or behavioral theories have been used within ERIPP research?"

METHODS

A systematic review of the literature was completed with an appraisal of bias risk using a custom critical appraisal tool. An electronic search of EBSCOhost (Academic Search Complete, CINAHL, Medline, Psychology and Behavioral Sciences Collection) and PubMed was completed from inception to October 2018. Studies investigating attitudes towards ERIPP participation with the use of a social or behavioral theoretical model or framework were eligible for inclusion.

RESULTS

The electronic search returned 7482 results and two articles were identified though a hand search, which resulted in ten articles meeting inclusion criteria. Four different behavioral or social theoretical models or frameworks were identified including the health action process approach model, health belief model, self-determination theory, and theory of planned behavior. Six studies utilized the theory at a B level meaning a theoretical construct was measured while four utilized the theory at the C level meaning the theory was tested. The mean critical appraisal score was 78%, indicating a majority of the studies were higher quality.

CONCLUSION

There has been an increase in the use of theory within literature that is specific to ERIPP participation. Additionally, the use of theory has shifted from guiding program design to the measurement of theoretical constructs and testing of the theoretical models.

Awareness of Anterior Cruciate Ligament Injury-Preventive Training Programs Among Female Collegiate Athletes

CONTEXT

Neuromuscular training programs can reduce the rate of noncontact anterior cruciate ligament (ACL) injuries, particularly in female athletes.

OBJECTIVE

To assess the awareness of, experience with, and factors associated with participation in preventive training programs (PTPs) among female collegiate athletes and their knowledge of ACL injuries.

DESIGN

Cross-sectional study.

SETTING

National Collegiate Athletic Association (NCAA) sports programs.

PATIENTS OR OTHER PARTICIPANTS

A total of 440 female NCAA athletes (age = 20 ± 1 years) representing 20 sports during the 2017-2018 academic year.

MAIN OUTCOME MEASURE(S)

We used a 12-item survey to collect data on each participant's age, sport, position, college, NCAA division, and awareness of and experience with PTPs. We performed descriptive statistics and used odds ratios (ORs) to assess relationships between demographic data and awareness of or interest in PTPs.

RESULTS

Of the 440 respondents, 85% (n = 373) knew that female athletes were at higher risk for sustaining ACL injuries than male athletes, and 89% (n = 391) knew that ACL injuries were preventable. Thirty-three percent (n = 143) were familiar with the concept of ACL PTPs. Only 15% (n = 64) had ever performed PTPs, but 89% (n = 391) reported they would perform a daily PTP if it could prevent ACL injuries. Fifty-two of the 64 respondents (81%) who had performed PTPs said athletic trainers or coaches oversaw the PTPs. Participants were more likely to be familiar with ACL PTPs if they (OR = 3.5; 95% confidence interval [CI] = 2.0, 5.8) or a teammate (OR = 4.6; 95% CI = 2.1, 9.8) had sustained an ACL injury. Respondents were more willing to perform PTPs if they (OR = 2.3; 95% CI = 0.80, 6.6) or a teammate (OR = 3.4; 95% CI = 1.8, 6.6) had sustained an ACL injury.

CONCLUSIONS

Although 89% of respondents expressed interest in performing daily ACL PTPs, only 15% had performed such programs, and only 33% were familiar with the concept of ACL PTPs.

Greater body mass index and hip abduction muscle strength predict noncontact anterior cruciate ligament injury in female Japanese high school basketball players

PURPOSE

This 3-year prospective study assessed risk factors for noncontact anterior cruciate ligament (ACL) injuries in female Japanese high school basketball players. Players suffering noncontact ACL injuries were assumed to demonstrate poorer hip abductor, knee flexor, and knee extensor muscle strength, as well as static balance, than those without injuries.

METHODS

One hundred and ninety-five new female high school basketball players underwent baseline examinations for various parameters during their first year of high school. After the baseline data were collected, all ACL injuries occurring over the subsequent 3 years were recorded. The assessment parameters between the noncontact ACL injury group and the control group were compared.

RESULTS

Of the 195 players, 24 were excluded due to pre-existing injuries present during the initial examination, quitting the basketball club during the follow-up period, or missing data. The remaining 171 players were observed for 3 years; unilateral noncontact ACL injuries were occurred in 12 players. Significantly lower general joint laxity and greater hip abductor strength were observed in the ACL injury group than in the control group. Body mass index (BMI) and hip abductor strength were significantly greater in the ACL injury group than in the control group, based on logistic regression analysis.

CONCLUSIONS

Greater BMI and hip abductor muscle strength were independent risk factors for noncontact ACL injuries in female Japanese high school basketball players. Although performing complete screens may be difficult, attention should be given to ACL injuries, particularly in highly competitive players with strong muscles.

Health Belief Model and Theory of Planned Behavior: A Theoretical Approach for Enhancing Lower Extremity Injury Prevention Program Participation

The integration of theoretical models into exercise-related injury prevention research may advance our understanding of the reasons why adoption and compliance of exercise-related injury prevention programs (ERIPPs) is low. A new model which integrates the Health Belief Model and Theory of Planned Behavior has been developed to provide insights into the behavioral determinants of ERIPP participation. There are several steps which must be taken to begin utilizing these theoretical models within ERIPP research, including creating an effective assessment tool, assessing the behavioral determinants of ERIPP participation within the target population, and developing and testing interventions based on these theoretical models.

Characterization of Prepractice Injury Prevention Exercises of High School Athletic Teams

Background:

Static and dynamic exercises are performed before activity to decrease injury risk and increase performance. Although evidence supports using dynamic over static stretching and performing Fédération Internationale de Football Association (FIFA) 11+ as a dynamic prepractice routine, we do not know the frequency at which these exercises are utilized in high school populations.

Hypothesis:

We hypothesize that there is a wide variety of preparticipation exercises performed by high school athletes, and that few high school teams perform FIFA 11+ as an injury prevention program in its entirety.

Study Design:

Observational study.

Level of Evidence:

Level 4.

Methods:

High school prepractice routines were observed for 185 teams (football, soccer, basketball, and lacrosse) over 1 season. The percentages of team warm-up routines that included components of FIFA 11+ were calculated, and the chi-square test was used to compare sex, sport, and level of competition.

Results:

Of a total 644 warm-up observations, 450 (69.9%) included only non–FIFA 11+ exercises, 56 (8.7%) included at least 1 FIFA 11+ exercise, and 38 (5.9%) included only jogging; 69 (10.6%) consisted only of sport-specific activities. The type of warm-up differed significantly between males and females (P = 0.002), sports (P < 0.001), and level of competition (P < 0.001). Static stretching and athletes stretching on their own were observed in 14% and 15% of all observations. No team performed the FIFA 11+ injury prevention routine in its entirety.

Conclusion:

The type of warm-up differed by sex, sport, and level of competition. Static stretching was performed more frequently than anticipated, and an entire FIFA 11+ warm-up was never performed.

Clinical Relevance:

We need to identify the exercises that decrease injury and increase performance and better inform the athletic population about the risks and benefits of static and dynamic warm-up programs.

Osteoarthritis action alliance consensus opinion - best practice features of anterior cruciate ligament and lower limb injury prevention programs

AIM

To identify best practice features of an anterior cruciate ligament (ACL) and lower limb injury prevention programs (IPPs) to reduce osteoarthritis (OA).

METHODS

This consensus statement started with us performing a systematic literature search for all relevant articles from 1960 through January 2017 in PubMed, Web of Science and CINAHL. The search strategy combined the Medical Subject Heading (MeSH) and keywords for terms: (1) ACL OR “knee injury” OR “anterior cruciate ligament”; (2) “prevention and control” OR “risk reduction” OR “injury prevention” OR “neuromuscular training”; and (3) meta-analysis OR “systematic review” OR “cohort study” OR randomized. We found 166 different titles. The abstracts were reviewed for pertinent papers. The papers were reviewed by at least two authors and consensus of best practice for IPP to prevent OA was obtained by conference calls and e-mail discussions. All authors participated in the discussion.

RESULTS

The best practice features of an IPP have the following six components: (1) lower extremity and core strengthening; (2) plyometrics; (3) continual feedback to athletes regarding proper technique; (4) sufficient dosage; (5) minimal-to-no additional equipment; and (6) balance training to help prevent injuries. Exercises focused on preventing ankle sprains, hamstring injuries and lateral trunk movements are important. Plyometric exercises should focus on correcting knee valgus movement. Exercises should focus on optimizing the hamstring to quadriceps strength ratio. In order for IPP to be successful, there should be increased education and verbal feedback along with increased athletic compliance. Additional equipment is not necessary. Balance training alone does not significantly reduce injuries, but is beneficial with other exercises. Not enough evidence to recommend stretching and agility exercises, with no ill effects identified. Therefore, we suggest making these optional features.

CONCLUSION

Best practice features for ACL and lower limb IPPs to help prevent OA contain six key components along with two optional.
