The effect of dynamic versus static visualizations on acquisition of basketball game actions: a diurnal study

This study aimed to examine the effect of time of day (TOD) on the acquisition of basketball game actions from dynamic and static visualizations in physical education students (novice practitioners). Participants were quasi-randomly assigned to three treatments (static pictures, enriched static-pictures, or video). Morning and late-afternoon sessions were conducted, involving study phases and immediate-recall tests [game comprehension (GC) test and game performance (GP) test]. Oral temperature (OT) and mood states (MS) were also measured. Compared to the morning, the results revealed that afternoon resulted in higher OT, higher negative MS (e.g., anxiety and fatigue), and lower positive MS (i.e., vigor) in all experimental conditions. Moreover, the results showed that: (a) GC and GP decreased throughout the day (regardless of treatments), (b) GC and GP were better with enriched static-pictures (with arrows) than with static pictures, at both TOD, and (c) the video resulted in better GC and GP than the two static presentations, at both TOD. This study (a) highlights the morning's superiority in the acquisition of motor skills from dynamic and static visualizations, due to mood disturbances and lower arousal levels, and (b) encourages basketball teachers to use video modeling by experts, particularly in the morning, for explaining tactical skills.

Personality profile of amateur team handball referees

Referees play a central role in competitive sport. Particularly in amateur sport, referees contribute significantly to making participation in sport possible for the masses. However, considering that every referee’s career starts at the grassroots level, it is very surprising that there has been no research on the personality traits of amateur referees so far. The current state of research indicates that personality is an essential component of the requirement profile of referees. Personality has been associated with job performance, particularly with regard to resilience and coping with pressure. Personality also affects effective game management in terms of influencing actions in the game in a preventative and proactive manner. This study, therefore, examines the personality profile of amateur handball referees (n = 582) for the first time using the German version of the Big Five Inventory 2 (BFI-2). Current data from German handball referees at the expert level and the German general population were used to compare and discuss the results. Except for lower scores in the domain of extraversion and the facets of sociability and energy level as well as a higher score in the facet of aesthetic sensitivity, amateur referees did not differ significantly from expert referees. In relation to the general population, the results indicate that handball referees, regardless of performance level, have higher scores in assertiveness, emotional stability, and responsibility. Our findings create awareness of personality traits in handball refereeing and illustrate the applied relevance of personality research, e.g., for coaching or recruitment activities.

Personality and Sport Experience of 20-29-Year-Old Polish Male Professional Athletes

More and more research reports assert that sport experience has an influence on shaping the personality of athletes. This paper aims at validating the connection between personality and sport experience. The research subject of were young Polish male athletes (N = 1,260) aged 20-29, out of 42 sports disciplines, with sport experience ranging from 3 to 12 years. In order to test the personality of the research subjects, a five-factor model of personality called the Big Five was applied. Statistical calculations and analyses were carried out with ver. 25 of the IBM SPSS Statistics software. The research has shown that all personality traits correlate in a statistically significant way with sport experience (p < 0.001): there is a negative correlation of sports experience with neuroticism and a positive correlation with traits such as extraversion, openness to experience, agreeableness, and conscientiousness. Thus, we have identified a relationship between sport experience and personality traits of the researched Polish male athletes-the longer the sport experience, the lower level of neuroticism and higher levels of extraversion, openness to experience, agreeableness, and conscientiousness. Duration of sport experience has a considerable influence on forming the personality of Polish male athletes. However, the interpretation of just the results regarding high level of extraversion and conscientiousness distinguishes Polish male athletes (20-29 years old) from the Polish male population of non-training people.

Predictive Strength of Contextual and Personal Variables in Soccer Players' Goal Orientations

Psychological variables, such as perceived motivational climate, goal orientation, self-determined motivation, and personality, have an influence on sports success performance. This study aimed to examine the relationships among a set of psychological variables (perceived motivational climate, goal orientation, self-determined motivation, and personality) in male and female footballers. Participants were 167 footballers (106 male, 61 female), aged 12 to 26, competing with clubs in the Spanish Football League. They all took four questionnaires aimed at evaluating motivational climate, goal orientations, self-determined motivation, and personality. The analyses of correlation and regression showed statistically significant relations among the variables. Neuroticism and psychoticism negatively relate to mastery motivational climate, the best predictor of self-determined motivation. It was concluded that contextual variables carry more weight in predicting goal orientations and self-determined motivation among participant footballers.

Personality Determinants of Success in Men's Sports in the Light of the Big Five

The aim of the study is to describe personality profiles and determinants of success in sports in relation to the Big Five Personality Model. In order to achieve this aim, personality profiles of players from various sports disciplines was set against the personality profile of champions—players who are considerably successful in sports competitions. Subsequently, an attempt was made to determine which personality traits significantly determine belonging to the group of champions—and therefore determine success in sport. The participants were men aged between 20 and 29 from the Polish population of sportsmen. A total of 1260 athletes were tested, out of whom 118 were qualified to the champions sample—those athletes had significant sports achievements. The research used the NEO-FFI Personality Questionnaire. Basic descriptive statistics, a series of Student’s t-tests for independent samples using the bootstrapping method, as well as a logistic regression model were performed. In relation to other athletes, champions were characterized by a lower level of neuroticism and a higher level of extraversion, openness to experience, agreeableness, and conscientiousness. An important personality determinant was neuroticism: the lower the level of neuroticism, the greater the probability of an athlete being classified as a champion. There are differences between champions and other athletes in all personality dimensions in terms of the Big Five. Based on the result of the research, it can be stated that personality differences should be seen as a consequence of athletes’ success, rather than as a reason for athletes’ success, based on their age between 20 and 29.

Assessment of Personality Traits Influencing the Performance of Men in Team Sports in Terms of the Big Five

The purpose of this article is to define the perspective from which a coach should analyze and evaluate personality traits that influence sports performance in team sports. The subjects of the research are Polish players (N = 300) in senior age (20–29 years) from 10 team sports (each n = 30). A sample of champions (n = 13) was selected from the study population, and the Big Five model was applied to examine their personality with the use of the NEO Five-Factor Inventory questionnaire. Statistical analyses were performed with the IBM SPSS Statistics software, version 25. The study revealed statistically significant differences between team sports in four personality traits: neuroticism, extraversion, agreeableness, and conscientiousness. Champions of team sports were characterized by a lower level of neuroticism, a higher level of extraversion, and openness to experiences in relation to other sportsmen. It was also confirmed that the personality traits distribution levels depend on the sport discipline. Therefore, an important role must be assigned to those mental training techniques that favor emotional balance, team communication, and tactical thinking skills and are manifested in triggering start-up readiness.

Wellbeing and flow in sports and music students during the COVID-19 pandemic

The aim of the study was to explore emotional and cognitive aspects of subjective wellbeing and flow in music and sports students during the lockdown imposed by the COVID-19 pandemic. Participants (314 higher education sports and music students) answered questions about measure of flow, satisfaction with life, satisfaction with studying, positive and negative affect, and COVID-19 impact. The results revealed differences in eight flow dimensions and a global flow score in favor of sports students. Differences were also found in affect: sports students experienced more positive affect and less negative affect than musicians. However, there were no significant differences with regard to satisfaction with life or satisfaction with study, and music and sports students perceived the COVID-19 impact equally. Gender differences were found for three flow dimensions and the global flow score (female students experienced flow less frequently than males) and satisfaction with studying (higher scores for female students). However, no gender differences were detected for satisfaction with life, positive and negative affect, or COVID-19 impact. The results of regression analyses showed that satisfaction with life and studying, positive and negative affect, and COVID-19 impact could all be predicted on the basis of flow dimensions.

Health and Wellbeing in Higher Education: A Comparison of Music and Sport Students Through the Framework of Self Determination Theory

Students in Higher Education report high levels of mental health issues and psychological distress. Paradoxical findings on performance-orientated students, such as athletes and musicians, suggest that the demands of highly skilled vocations may enhance wellbeing while being detrimental to physical and mental health. To provide timely and appropriate help, institutions need to understand what areas of health and wellbeing are compromised in different student groups. In this study, we compared performance-orientated (music and sport) students to other students and the general population on a selection of wellbeing (WHO5, PWS, and WEMWBS), mental and physical health (K10, SF12, and PHQ9), and trait measures (TIPI, LOT-R, and PCS). Through an online survey (N = 273), data were collected from bachelor and master students (n = 135 music, n = 67 sport, n = 71 controls). Students' scores were compared to the general population, where norm values were available, and analyzed within and between groups. Multiple regression was performed to investigate trait measures as predictors of wellbeing. All groups scored significantly below population norms for wellbeing and mental health. One third were classed as having moderate to severe depression. Musicians scored higher openness to experience than athletes. While sport students showed a highly homogenous within-group profile, music students' scores differed significantly across study courses (e.g., performance and composition). Predictors for wellbeing were: optimism and emotional stability (all students); additionally conscientiousness (sport and music); and perceived competence (music only). As expected, students reported more health and wellbeing issues than general population. Distinct profiles of wellbeing were apparent for performance-orientated students. Results are in line with Self Determination Theory and suggest the need for institutions to embed health and wellbeing into a 'living curriculum' to accommodate the needs of different student groups. The WHO5 emerged as a parsimonious yet sensitive measure for mental health and wellbeing in student populations.

The Main Dimensions of Sport Personality Traits: A Lexical Approach

To uncover the main dimensions of sport personality traits, a lexical study was conducted. In the first two phases, 321 adjectives denoting the way somebody practices sports were selected. In the third phase, 555 respondents self-rated the adjectives. Congruence analyses provided evidence of six factors, five of which are sport personality trait factors (friendly fairness, resilience, drive, perfectionism, and inventiveness) plus one physical individual difference factor (agility). Marker scales from the sport personality trait factors show convergent correlations with the generic HEXACO personality obtained years earlier. Furthermore, meaningful relations with the six most frequently practiced sport and leisure activities were observed. Contextualized sport personality trait factors can be useful in research on sport preferences, sport behaviors, and sport outcomes.

The Role of Sports Practice in Young Adolescent Development of Moral Competence

The study examined the moral competence levels in adolescents participating in individual/team sports compared with those not undertaking sports at all. In total, 827 students aged 15–17 years old (45.4% boys, 54.6% girls) from randomly selected secondary schools in the Wielkopolska region in Poland participated in the study. The moral competences were assessed using the Lind’s Moral Competence Test. The students also answered questions concerning their statues of involvement in sport (not involved; amateur; professional), years of involvement, and the type of sport they partook in (individual/team). The results highlight that the moral competence level in most of the examined adolescents (71.6% girls, 76.8% boys) was low. Those who presented a high moral competence level were 10.4% in girls, 8% in boys. There was no interaction between modes of involvement in sport and moral competence when comparing adolescents. The moral competence levels were not correlated with years of training in either mode of involvement or with type of sports. Therefore, we assume that, at this age, the type of sport and the level of engagement do not differentiate moral competence level and that there must be more factors contributing to this. This opens new directions for further research on the role of external factors stimulating the socio-moral growth of youth.

Personality Traits in Marathon Runners and Sedentary Controls With MMPI-2-RF

Background

Endurance exercise in general and marathon running in particular have become increasingly popular over the past decades. Recent investigations about personality structures in this cohort and comparisons to non-active cohorts are lacking.

Methods

In the ReCaP study (Running effects on Cognition and Plasticity), a total of 100 marathon runners and 46 sedentary controls were recruited. After elimination of Minnesota Multiphasic Personality Inventory 2 Restructured Form (MMPI-2-RF) profiles with insufficient validity, 79 marathon runners (MA) and 27 sedentary controls (SC) remained for final analyses. Depressive symptoms were evaluated with Beck Depression Inventory (BDI) and Hamilton Depression Scale (HAMD).

Results

Marathon runners had lower scores in scales measuring somatic and cognitive complaints, stress, demoralization, hopelessness and distrust. Within the marathon group, committed runners exhibited hypomanic traits compared to regular runners.

Discussion and Conclusion

Personality differences could be summarized as (sub-)depressive personality traits in SC compared to MA rather than typical (sub-) depressive symptoms in the meaning of depressive disorders. Future studies should further evaluate cause and consequence of endurance training and hypomanic or euthymic symptoms, as a two-way interaction exists.

Injury-Related Behavioral Variables in Alpine Skiers, Snowboarders, and Ski Tourers-A Matched and Enlarged Re-Analysis

Behavioral variables might play an important role in explaining the differences in injury rates across winter sport disciplines and injury prevention programs might be more specifically designed based on this knowledge. On ski slopes, alpine skiing, snowboarding, and ski touring are the predominant winter sport disciplines. Therefore, the aim of the present study was to investigate possible differences in injury-related behavioral variables between practitioners of these disciplines. Using a matched re-analysis approach of a cross-sectional survey, 414 winter sport participants (alpine skiers, snowboarders, ski tourers, each n = 138) were analyzed on the differences in sensation seeking, treated injuries, and injury-related behavioral variables. Cochran-Mantel-Haenszel and Friedman tests revealed significantly higher sensation seeking, p < 0.001, and a significantly higher percentage of participants reporting to have consumed alcohol in the past five skiing days, p = 0.006, in snowboarders compared to alpine skiers. The participants with treated injuries showed higher sensation seeking, p < 0.050, and a higher percentage of snowboarders, p = 0.020, compared to participants without treated injuries. Injury prevention programs for snowboarders, who remain an important risk group for injury prevention, might benefit from considering a possibly higher percentage of alcohol-consuming participants and from providing information on injury-related risks of sensation seeking.

Defining Extreme Sport: Conceptions and Misconceptions

One feature of how sport is defined is the distinction between extreme and non-extreme sport. BASE jumping is an example of an "extreme sport" because it involves a high degree of risk, whilst swimming is classified as "non-extreme" because the risks involved are minimal. This broad definition falls short of identifying the extent of risk and ignores the psychological, social-demographic and life style variables associated with engagement in each sport.

In the Zone: An Exploration of Personal Characteristics Underlying Affective Responses to Heavy Exercise

Positive affective responses to exercise have been linked to longer-term adherence. The dual-mode model indicates that affective responses during heavy exercise (between the ventilatory threshold and the respiratory compensation point) are subject to interindividual variability (zone of response variability). Participants (N = 48) completed measures to assess personal characteristics prior to a graded exercise test. Responses to the Feeling Scale were recorded during the graded exercise test and subsequently used to group participants as either negative responders or neutral/positive responders to heavy exercise. Discriminant function analysis was applied, and a significant weighted linear composite predicted affective response. Preference for exercise intensity and sex were significant predictors (p = .003). Negative responders had lower preference scores and were more likely to be men. The combination of these two variables successfully predicted group membership 71% of the time. Individual differences appear relevant when examining affective responses to heavy exercise.

Personality differences amongst drag racers and archers: implications for sport injury rehabilitation

Personality trait of an athlete is a significant factor in sports injury rehabilitation. The aim of the present study is to investigate whether there are differences in personality traits between male and female, professional and amateur athletes from sports representing two ends of extreme to traditional namely; drag racing and archery. Overall 189 male and female, professional and amateur drag racers (n=144) and archers (n=45) took part in this study. Participants completed the personality traits of extroversion and neuroticism as measured by Eysenck's classic Personality Inventory dimensions and thrill and adventure seeking (TAS), experience seeking (ES), disinhibition (DIS), boredom susceptibility (BS), and sensation seeking (SS) as measured by Zuckerman's Sensation Seeking Scale. The results showed that professionals scored significantly lower on neuroticism compared to amateurs. Drag racers scored significantly higher on TAS, DIS, and SS compared to archers and there were gender differences amongst archers on TAS and SS with males scoring higher than females. Such differences in personality factors and the readiness to take risks, lack of caution, and adventurous spirit can influence the risk of injury in athletes and indeed may influence the outcome of rehabilitation. Practitioners would need to recognise difference in personality traits associated with the type of sport and the choice of interventions strategies.

Physiological underarousal as a mechanism of aggressive behavior in university athletes with a history of concussion

INTRODUCTION

Research has indicated that athletes who engage in high-risk athletic activities, such as football and hockey, have riskier personalities than their low-risk and nonathlete counterparts (Ahmadi et al., 2011, Procedia Soc Behav Sci, 30 and 247-251; Zuckerman, 1983, Biological bases of sensation seeking, impulsivity, and anxiety, Lawrence Erlbaum Assoc Inc.). For instance, increased sensation-seeking and aggression are common in high-risk athletes, rendering these individuals more likely to sustain a subsequent injury, such as concussion. Elevated levels of certain personality traits, including impulsivity and aggression, have also been observed after concussion (Goswami et al., 2016, Brain Struct Funct, 221 and 1911-1925). The purpose of this study therefore was to determine whether aggressive behavior in university athletes may be accounted for, in part, by a history of concussion, rather than exclusively athletic status.

METHODS

Using a quasi-experimental design, 66 university students (n = 18 nonathletes, n = 24 low-risk athletes, n = 24 high-risk athletes) with (n = 27) and without a history of concussion (n = 39) completed the Buss & Perry Aggression Questionnaire (BPAQ; Buss & Perry, , J Pers Soc Psychol, 63 and 452) and provided electrodermal activation (EDA) as an index of physiological arousal.

RESULTS

It was found that decreased physiological arousal among students with a history of concussion was associated with greater endorsement of physical aggression. Moreover, athletic status did not account for this pattern of aggression, as athletes and nonathletes did not differ in terms of self-reported aggressive tendencies.

CONCLUSIONS

Physiological compromise after concussive injury may act as an independent mechanism of aggressive behavior in athletes beyond factors, such as athletic status.

Temperament and chronotype among academic athletes – perspective of the regulative theory of temperament

<b>Background</b><br /> The aim of the research was to evaluate the relationship between chronotype and temperamental traits and temperament structure specified in the Regulative Theory of Temperament among physical education students who are actively engaged in sport. The analyses were performed separately in groups of men, women, and individual and team sports representatives. <br /> <br /> <b>Participants and procedure </b><br /> The study included 157 participants (women n = 35, men n = 122; individual sports n = 88 and team sports n = 69). Measures used in the study were the Formal Characteristics of Behaviour – Temperament Inventory (FCB-TI) and the Morningness-Eveningness Questionnaire (MEQ). <br /> <br /> <b>Results </b><br /> Among women and men chronotype was positively correlated with Briskness (BR) and Endurance (EN). In women chronotype was negatively related to Emotional Reactivity (ER). Sensory Sensitivity (SS) was positively associated with chronotype in men. In the individual sport group chronotype was associated with four temperamental traits: BR, EN, ER (negatively) and SS. Activity (AC) significantly correlated with chronotype in the team sport group. Two out of three indicators of temperament structure – potential for stimulation processing (MPS) and structure harmony parameter (Zh1) – were related to chronotype in both genders. <br /> <br /> <b>Conclusions</b><br /> The results obtained in the present research indicate that temperament is significantly related to chronotype. Evening chronotype men and women might be overstimulated and morning types might be understimulated. These data might be useful for coaches and provide a guide for further individualization of the training process.

"I Wanna Be the Very Best!" Agreeableness and Perseverance Predict Sustained Playing to Pokémon Go: A Longitudinal Study

OBJECTIVE

The smartphone game Pokémon Go™ has attracted much scientific attention regarding its potential health-related outcomes. Most studies, however, limited their investigation to short-term outcomes. The aim of the present study is to investigate the role of personality traits in predicting sustained playing to the game on a 6-month period as well as related health outcomes in terms of distance walked per day.

MATERIALS AND METHODS

Pokémon Go players from 10 countries were recruited through social media and answered an online questionnaire. At Phase I (August 2016), 402 participants provided their game statistics and filled an extensive personality inventory (six main personality traits, impulsivity, need for cognition, need for closure, competitiveness, and self-efficacy). At Phase II (December 2016), 151 participants indicated whether they were still playing or not and provided updated game statistics.

RESULTS

No personality traits predicted the distance walked by the players. However, the probability of still being playing the game at Phase II was positively predicted by three personality traits: agreeableness, perseverance, and premeditation. Distance walked per day significantly decreased between Phases I and II but remained substantial.

CONCLUSION

This study identified three personality traits that predicted sustained playing and thus potentially higher game-related physical activity in the long run. In comparison with prior work, this study goes a step forward by (i) investigating personality traits underlying use of the game and related health outcomes, and (ii) providing longitudinal data concerning the use of the game. Findings open new perspectives for the development of other exergames.

Personality and performance: moving beyond the Big 5

In this review, we examine the literature in relation to personality and performance. Much of the extant work in this area has focused on the role of the Big 5 traits (i.e., extraversion, conscientiousness, openness to experience, agreeableness, and neuroticism), at the expense of other personality variables that have a strong performance-focused rationale. Further, a focus on main effects has dominated the literature, without recourse to consider person×environment interactions. In this review we go beyond the Big 5 and consider the role of two personality traits, narcissism and alexithymia, in relation to performance. We demonstrate that both traits have considerable potential to explain differences in performance and that the personality-performance relationship is best viewed from an interactionist perspective. We close with a call for researchers to give more attention to personality in relation to performance.

Factor Analysis of the Relationships between Personality and Motor Characteristics of Men and Women

To identify possible relationships among 16 motor and 11 personality variables, 152 women and 77 men, ages 22 to 30 yr., were tested, using factor analysis with varimax rotation. The hypotheses were that (1) specific personality characteristics are related to specific motor characteristics, (2) motor and personality characteristics are clustered in a common structure, (3) sex differences exist in the relations between personality and motor performance. Analyses confirmed Hypotheses 1 and 3. Only two of the 11 tested personality variables (Extraversion and ability to delay gratification) were related to some of the motor variables, Reaction time, Balance, and Kinesthesis. These relations as well as the factorial structure differed for men and women. As the personality and motor variables were not clustered in common factorial pattern for both sexes, Hypothesis 2 was rejected.

Personality, Aggressivity and Recreational Preference in Behaviourally Disturbed and Non-Disturbed Boys

A vast amount of research has been conducted in the area of personality differences between 'behaviourally disturbed' and 'non-disturbed' children. In a classical analysis of delinquents, Burt (1944) found they were characterized as being less intelligent, possessing heightened levels of excitability and toughmindedness (unsentimental, insensitive and solitary). Shrider (1962) and Pennington (1954) employed the HSPQ and found delinquents to be lower in intelligence, thicker-skinned (impulsive, adventurous and active), lacking in social ego-strength and more radical and experimental. Glueck and Glueck (1950) and Hathaway and Monashesi (1953) had made comparisons between delinquents and non-delinquents; the delinquent group were discriminably less emotionally stable, less serious and inhibited, unfriendly, dominant, liable to display greater mood fluctuations and more adventurous. Cattell, Tastsuoka and Eber (1970) had found a division of personality disorders which roughly correspond to the neuroses and the problems of behaviour or conduct disorders characterized by such factors as affectothymia, dominance or ascendence and lowered super-ego strength. Cattell and Cattell (1975) had shown delinquents to be demonstrably more solitary, less intelligent, more easily aroused, guiltprone, nervous and excitable. Eysenck (1960), in submitting data to factorial analysis (taken from children referred to guidance clinics), was able to distinguish between those with conduct disorders (typically extraverted neurotic), tending to swear, steal, be rude, aggressive and egocentric, with those children manifesting personality problems (introverted neurotic), who were likely to be depressed, seclusive, nervous and sensitive.

Autonomy Mediates the Relationship between Personality and Physical Activity: An Application of Self-Determination Theory

This study sought to examine tenets of Self-Determination Theory by testing a mediation model of physical activity and personality via autonomy. A total of 290 adults were recruited to complete a one-time online survey of exercise habits and individual characteristics. Surveys assessed personality, autonomy, and physical activity. A measurement model specifying direct effects between personality dimensions and physical activity and indirect effects operating through autonomy provided an excellent fit to the data (Χ² = 0.66, df = 3, p = 0.88, RMSEA(90% CI) = 0.00 (0.00–0.05), CFI = 0.99, SRMR = 0.01). Results indicated significant (p < 0.05) effects of Extroversion (β = 0.42), Conscientiousness (β = 0.96), and Emotional Stability (β = 0.60) on autonomy, which in turn, was significantly associated with physical activity (β = 0.55). No significant effects were observed for Agreeableness or Intellect. None of the personality constructs were found to be directly associated with physical activity. This model accounted for 27% of the variance in physical activity. The results of this study suggest that autonomy is significantly associated with physical activity. Therefore, attempts to improve autonomy in individuals may be a useful intervention strategy in improving physical activity levels.

Role of self-reported individual differences in preference for and tolerance of exercise intensity in fitness testing performance

Performance in fitness tests could depend on factors beyond the bioenergetic and skeletomuscular systems, such as individual differences in preference for and tolerance of different levels of exercise-induced somatosensory stimulation. Although such individual-difference variables could play a role in exercise testing and prescription, they have been understudied. The purpose of these studies was to examine the relationships of self-reported preference for and tolerance of exercise intensity with performance in fitness tests. Participants in study I were 516 men and women volunteers from a campus community, and participants in study II were 42 men recruit firefighters undergoing a 6-week training program. Both the Preference and Tolerance scores exhibited significant relationships with performance in several fitness tests and with body composition and physical activity participation. Preference and Tolerance did not change after the training program in study II, despite improvements in objective and perceived fitness, supporting their conceptualization as dispositional traits. Preference and Tolerance scores could be useful not only in ameliorating the current understanding of the determinants of physical performance, but also in personalizing exercise prescriptions and, thus, delivering exercise experiences that are more pleasant, tolerable, and sustainable.

Vocational and Leisure Interests

Although much attention has been devoted to examining the measurement of vocational interests, much less attention has been directed to studying leisure interests, despite suggestions for incorporation of leisure interests into career counseling, particularly for college students. Furthermore, research on the relations between leisure and vocational interests highlights that some leisure interests are highly related to vocational interests, such as interests in Social, Artistic, and Realistic activities. To advance understanding on interests and the relations between leisure and vocational interests, the current study used Latent Profile Analysis, a novel approach to examining interest profiles that identifies groups of individuals with similar profiles. Support was found for seven different interest profiles in a sample of college students. Additionally, a number of mean differences on work values, work centrality, and personality traits among the seven profiles were examined.

I'm outgoing and she's reserved: the reciprocal dynamics of personality in close friendships in young adulthood

Close college-age friendships provide differential opportunities for reinforcing dispositional tendencies and fostering accommodation or change. This finding was obtained from a cross-sectional study of 66 pairs of same-sex college-age friends (58% female). Each pair of friends was extreme and either very similar or different with regard to extraversion-introversion. Interviews with each friend were analyzed for references to each other's role in various friendship domains, including the setting of the friendship and position with regard to chatting, disclosing, expressing opinions about peers, and energizing the friendship. Matched friends mutually reinforced each other's similar dispositional tendencies. Friends with contrasting personalities showed patterns of personality accommodation as well as complementary reinforcement. Implications are discussed for embedding reciprocal theories of personality development in close friendships.

Extraversion and Motor Response Initiation

This article explores the contribution of differences in motor response initiation and execution to the biological bases of extraversion. Specifically, we examined individual differences in the lateralized readiness potential (LRP) for introverts and extraverts under conditions influencing stimulus evaluation time prior to response execution, i.e., stimulus information value and tonal complexity. The salient effects were longer stimulus-locked LRP and shorter response-locked LRP for extraverts than introverts to simple imperative stimuli to respond. The present studies (1) confirm that extraverts initiate movement faster and are less efficient than introverts in the processing of simple stimulus signals to respond and (2) endorse the view differences in sensory-motor processing are important determinants of variation in Extraversion.

Sporting achievement: what is the contribution of digit ratio?

Second-to-fourth digit ratio, a marker for prenatal testosterone levels, has been shown to be associated with sporting achievement in men. It is unclear, however, whether digit ratio makes a contribution over and above salient personality variables. The present study, which included female participants, measured four personality traits and one cognitive ability (mental rotation) that have been linked to both sports achievement and sex. The significant relationship between digit ratio and sporting achievement was nearly identical in women and men. A multiple regression showed that when significant correlates of sporting ability (weight, height, years playing, hours per week training, social potency, and mental rotation) were entered first, the contribution of digit ratio remained highly significant. We suggest that physiological as well as psychological factors may be an important avenue for future study.

PERSONALITY CHARACTERISTICS OF MARTIAL ARTISTS

This study used the MMPI-2 to explore the personalities of yellow-belt and black-belt martial artists. A total of 40 participants completed the MMPI-2 and a demographic questionnaire. Black-belt females tended to be less defensive than were other martial artists, but also displayed more paranoia and more anger than average. Females of both ranks reported a higher degree of anxiety and health concerns than did males in the study, and black-belt females also reported more family problems than did other groups. Finally, black belts in general reported more health concerns than did yellow belts.

Is the Relationship of RPE to Psychological Factors Intensity-Dependent?

PURPOSE

Although ample evidence shows that ratings of perceived exertion (RPE) are correlated with psychological variables, whether and how these relationships change as a function of exercise intensity remains unclear. The purpose of this study was to examine the correlations of RPE with both dispositional (extraversion, neuroticism, behavioral activation, behavioral inhibition) and situational (self-efficacy) psychological variables across three exercise intensities. Based on the social-psychophysiological model proposed by Rejeski, it was hypothesized that the correlations would be weakened as the intensity increased.

METHODS

Thirty young and healthy volunteers participated in three 15-min treadmill runs, one 20% VO2max below, one at, and one 10% VO2max above the ventilatory threshold. RPE was assessed at minutes 3, 6, 9, 12, and 15.

RESULTS

Extraversion, behavioral activation, and self-efficacy showed significant negative correlations with RPE at lower but not higher intensities, whereas neuroticism was unrelated to RPE and behavioral inhibition was positively related across all three levels of intensity.

CONCLUSIONS

The results provide partial support to the hypothesis that the relationship of dispositional and situational psychological factors to RPE changes systematically, becoming weaker at higher exercise intensities. This may have implications for the effectiveness of personality-based adjustments of exercise prescriptions and cognitive techniques for dealing with aversive sensations of exertion.

Gender, eating behavior, and personality characteristics in physically active students

The aim of this paper was to examine associations between personality traits, eating disorder (ED) behavior, exercise, and gender. The participants (n=1482: 905 women and 577 men) were students from four universities in Norway. The subjects filled out a compound questionnaire including demographics, weekly hours of exercise, type of sport, Karolinska Scales of Personality (KSP), and the Eating Disorder Inventory (EDI). Because of the data collection procedure, it is difficult to provide a clear-cut response rate in this study. The results showed that the risk ratio for women who scored 40 or higher on the EDI was three times higher compared with men. ED behavior did not seem to be associated with high weekly hours of physical activity in general. There were significant gender differences in personality traits. However, women and men with high scores on the EDI showed no differences on the KSP scales, except on "detachment" and "indirect aggression". The most important predictors for weekly hours of physical activity were the EDI scales "drive for thinness" and "body dissatisfaction", and the personality variables "extraversion" and "neuroticism". The factors that contributed most to the differences between students who scored 40 or higher on the EDI and those who scored below 40 on the EDI were neuroticism, BMI, gender, and age.

Line-bisecting performance in highly skilled athletes: Does preponderance of rightward error reflect unique cortical organization and functioning?

A line-bisecting test was administered to 250 highly skilled right-handed athletes and a control group of 60 right-handed age matched non-athletes. Results revealed that athletes made overwhelmingly more rightward errors than non-athletes, who predominantly bisected lines to the left of the veridical center. These findings were interpreted in the context of previous EEG research on athletes and brain localization studies of select personality traits. A preliminary theory (Group Cortical Organization and Activation Theory) that highly skilled athletes and other specific homogeneous populations may have developed a unique cortical organization or response system that mediates relative tendencies in cerebral activation was advanced. The potential utility of the line-bisecting test as an assessment and intervention tool in sports was discussed.

Psychological factors in sport performance: the Mental Health Model revisited

The Mental Health Model (MHM) of sport performance purports that an inverse relationship exists between psychopathology and sport performance. The model postulates that as an athlete's mental health either worsens or improves performance should fall or rise accordingly, and there is now considerable support for this view. Studies have shown that between 70 and 85% of successful and unsuccessful athletes can be identified using general psychological measures of personality structure and mood state, a level superior to chance but insufficient for the purpose of selecting athletes. Longitudinal MHM research indicates that the mood state responses of athletes exhibit a dose-response relationship with their training load, a finding that has shown potential for reducing the incidence of the staleness syndrome in athletes who undergo intensive physical training. The MHM also has implications for the general care of athletes as support services have traditionally been limited to preventing or treating physical problems. Despite its simple premise and empirical support, the MHM has often been mischaracterised in the sport psychology literature and recently some authors have questioned its validity. This overview will summarise MHM research, including the more recent work involving the model's dynamic features in an effort to resolve disputes surrounding the model.

Injury proneness and personality

The aim of this research was to investigate some personality factors among groups of 43 physically injured inpatients and 43 non-injured hospital-based controls. The participants completed the Eysenck Personality Questionnaire (EPQ) and the Coping Styles Questionnaire (CSQ). Logistic regression was used to compare the two groups on six psychological risk factors. The univariate regression models suggested three possible risk factors: extraversion, sensitization, and avoidance coping style. The multivariate regression model supported only extraversion and sensitization of emotion. Next, patients in the experimental group were questioned about whether they had considered preventive measures before the accident and whether they felt responsible for their injuries. Correlation analysis showed that introverted subjects felt more responsible for the sustained injuries than their extraverted counterparts. Sensitizers and subjects who scored high on psychoticism, neuroticism, and emotional coping had not considered preventive measures as often as others. Finally, the principal component analysis of risk factors was used to extract two correlates of injury-prone behaviour: extraversion and sensitized avoidance. It was concluded that psychological factors play an important role in predicting injury that is significant enough to require inpatient treatment. Two potential mechanisms of psychological impact have been suggested, notably distraction in extraverted subjects and overestimation in sensitizing avoiders.

Laboratory measurement of aggression in high school age athletes: provocation in a nonsporting context

This study investigated the relationship between aggression and type of sports involvement in high school age boys. Athletes (16 boys), ages 15 to 18 years, were separated into two groups, one of 8 athletes who participated in sports with high physical contact, e.g., football and basketball, and the other of 8 athletes who participated in low contact sports, e.g., track and baseball. Students participated in six 25-min. Point Subtraction Aggression Paradigm sessions. The paradigm is an established laboratory model of aggression with three response options: (1) a point-maintained response, (2) an aggressive response, and (3) an escape response. Analysis indicated that the only difference between the groups was that individuals who participated in high contact sports emitted significantly more aggressive responses than individuals who participated in low contact sports. Similarly, psychometric measures of aggression indicated that individuals in the former group self-reported more behavioral incidents of aggression than those in the latter group.

The relationship between eating disorders and personality in physically active women

The aim of the study was to examine the relationship between personality factors, self-reported eating disorders, type of physical activity, level of sport competition and hours spent on physical activity each week among physically active non-athletes and athletes. A total of 591 high school women participated in the study. The mean age was 19 during the data collection. Scores were obtained on the Karolinska Scales of Personality (KSP) and a questionnaire concerning eating disorders (1) and physical activity. All diagnoses were based upon the DSM-IV criteria for anorexia nervosa (AN), bulimia nervosa (BN) and eating disorder not otherwise specified (EDNOS). The prevalence of AN was 1.5%, BN 2.0%, AN+BN 0.3% and EDNOS 12.9%. The prevalence of eating disorders (ED) was highest among physically active non-athletes who were members of fitness clubs (odds ratio (OR)= 1.86, 95% CI: 1.08-2.79). However, there was no relationship between the prevalence of eating disorders and the level of sport competition or time spent on physical activity. The results showed that women with eating disorders scored higher in anxiety, hostility and detachment, and lower in socialisation than the women without eating disorders. The results indicated that individuals with certain personality characteristics had a higher risk for being classified with ED, but it does not seem to be related to whether they are physically active or not. The findings in this study may support the hypothesis that participating in physical activity can have some positive psychological effects, but this does not necessarily apply to patients with AN and BN. ED may have a biological/genetic explanation according to Eysenck's personality theory.
