An examination of psychosocial variables moderating the relationship between life stress and injury time-loss among athletes of a high standard

Based on Williams and Andersen's model of stress and athletic injury, six psychosocial variables were assessed as possible moderators of the relationship between life stress and injury among 121 athletes (65 males, 56 females) competing in a variety of sports at state, national or international level. No significant effects of the sex of the participants were evident. Correlational analyses revealed moderator effects of several variables. Specifically, dispositional optimism and hardiness were related to decreased injury time-loss in athletes when positive life change increased, and global self-esteem was associated with decreased injury time-loss when both negative life change and total life change increased. The results indicate that athletes with more optimism, hardiness or global self-esteem may cope more effectively with life change stress, resulting in reduced injury vulnerability and recovery rates.     

An examination of the relationship between destination image and marathon participants’ behaviours

ABSTRACT

The purpose of this study was to examine the relationship between the destination image and behaviours of marathon participants with different levels of behavioural running involvement. This study focused on the Kyoto Marathon in Japan. The survey was conducted on marathon participants. The data of marathon participants was obtained through the Kyoto Marathon 2017 runner survey website. The participants were classified into two groups by cluster analysis – those with high running involvement and those with low running involvement using their experience of marathon events and running history variables. A comprehensive destination image scale was used to assess the practical implications of a sport event. MANOVA and ANOVA were used to test the influence of running involvement on a marathon participant’s destination image perceptions, place attachment, satisfaction and behavioural intentions. These results do not support the role of sport involvement in terms of the key-dependent variables of the study, namely place identity and dependence, intentions to participate in the event again and destination image perceptions. However, the influence of destination image factors and event satisfaction were still evident in their ability to predict sport event tourist intentions to revisit a sport event that is held in the same destination every year.

The relationship between motivational climate, perceived ability and sources of distress among elite athletes

Situational factors as well as individual differences are assumed to play an important role in perceptions of stress. One factor that may affect an elite athlete's perception of stress may be his or her perceived motivational climate. To examine the relative importance of dispositional and situational factors on the perceptions of distress (i.e. negative stress), we assessed goal orientations, perception of motivational climate and sources of distress among Norwegian participants at the 1994 Winter Olympic Games in Lillehammer. Perception of a performance climate was associated with cognitive sources of distress, the coach, and team aspects as a source of distress. Furthermore, a performance climate was a significant predictor of high total distress. The athletes with lower perceptions of ability perceived the coach to be more a source of distress than athletes with a high perception of ability. A perception of a mastery climate was negatively associated with the coach as a source of distress. These findings indicate that, to reduce the perception of distress, the coach should focus on creating a mastery climate for elite athletes.

An examination of the relationship between athlete leadership and cohesion using social network analysis

Two studies investigated the structure of different athlete leadership networks and its relationship to cohesion using social network analysis. In Study 1, we examined the relationship between a general leadership quality network and task and social cohesion as measured by the Group Environment Questionnaire (GEQ). In Study 2, we investigated the leadership networks for four different athlete leadership roles (task, motivational, social and external) and their association with task and social cohesion networks. In Study 1, the results demonstrated that the general leadership quality network was positively related to task and social cohesion. The results from Study 2 indicated positive correlations between the four leadership networks and task and social cohesion networks. Further, the motivational leadership network emerged as the strongest predictor of the task cohesion network, while the social leadership network was the strongest predictor of the social cohesion network. The results complement a growing body of research indicating that athlete leadership has a positive association with cohesion.

The moderating effect of physical activity on the relationship between bullying and mental health among sexual and gender minority youth

BackgroundSexual and gender minority youth frequently experience bullying, which often contributes to higher depressive symptoms and lower self-esteem. Given that physical activity (PA) can mitigate depressive symptoms and improve self-esteem, we examined the moderating effect of PA on the relationship between bullying and mental health among sexual and gender minority youth.MethodsData from the Lesbian, Gay, Bisexual, Transgender, and Queer National Teen Survey (n = 9890) were analyzed. Hierarchical regression analyses examined the influence of history and frequency of being bullied, PA, and the interaction of these variables on depressive symptoms and self-esteem. Simple slopes analyses were used to probe significant interactions.ResultsResults indicated the importance of accounting for bullying history when examining effects of PA on mental health. PA was negatively related to depression (t = –4.18, p < 0.001) and positively related to self-esteem (t = 12.11, p < 0.001). Bullying frequency was positively related to depression (t = 19.35, p < 0.001) and negatively related to self-esteem (t = –12.46, p < 0.001). There was a significant interaction between bullying frequency and PA for depression (t = 4.45, p < 0.001) and self-esteem (t = –4.69, p < 0.001). Post hoc analyses suggested that the positive effects of PA on mental health may be limited to those not bullied because it had a negligible effect on those who were bullied.ConclusionResults suggest that sexual and gender minority youth exercise interventions aiming to improve mental health should first address bullying history; otherwise, their effectiveness may be limited to those who have been bullied.     

Discriminant analysis of anthropometric and biomotor variables among elite adolescent female athletes in four sports

The aim of this study was to identify anthropometric and biomotor variables that discriminated among groups of elite adolescent female athletes aged 14.3 +/- 1.3 years (mean +/- s) from four different sports (tennis, n = 15; swimming, n = 23; figure skating, n = 46; volleyball, n = 16). The anthropometric variables included body mass, height, bi-epicondylar breadth of the distal extremity of the humerus and femur, maximal girth of the calf and biceps and the sum of five adipose skinfolds. The biomotor variables were maximal aerobic power, muscular endurance and flexibility of the trunk. Discriminant analysis revealed three significant functions (P < 0. 05). The first discriminant function primarily represented differences between figure skaters and all other groups of athletes. The other two underlined anthropometric and biomotor differences between swimmers and volleyball players and between tennis players and swimmers, respectively. After validation, the analysis showed that 88% of the athletes were correctly classified in their respective sports. Our model confirms that elite adolescent female athletes show physical and biomotor differences that clearly distinguish them according to their particular sport.

Effects of psychosocial variables in the similarity and interdependence of physical activity levels among adolescent best friend dyads

Given that physical activity (PA) tends to decrease with age during adolescence, addressing factors that affect change is important. This study examined the similarity and interdependence of PA as influenced by psychosocial factors among adolescent best friend dyads. A total of 660 adolescents, representing 330 best friend dyads, completed questionnaires with regard to PA, sitting time, perceived exercise benefits and barriers, physical self-perception and social support for PA. Dyads were also identified as reciprocal and non-reciprocal best friends; reciprocal means that both considered each other best friends and non-reciprocal were those in which only one considered the other a best friend. Data were analysed using a hierarchical linear model framework. Results indicated significant similarities between reciprocal best friend dyads for PA and sitting time, and for sitting time in non-reciprocal best friends (P values <.01). Psychosocial variables were associated with PA in reciprocal best friend dyads and with sitting time in reciprocal and non-reciprocal best friend dyads. Best friend gender, regular sports practice of the person, perceived exercise barriers of the best friend and best friend social support were the best predictors for PA.     

A cross-level moderating effect of team trust on the relationship between transformational leadership and cohesion

ABSTRACT

We draw on the concept of the shared mental model to explain the cross-level direct and moderating effects of team trust on the relationship between coach transformational leadership and cohesion. Using hierarchical linear modelling, we analysed 597 national level high school and university volleyball players to test our research model. Our results revealed that, (a) at the individual level, coach transformational leadership has a positive effect on athletes’ perceptions on cohesion and (b) team trust, a group-level construct, is positively related to social cohesion and moderates the coach transformational leadership-cohesion relationship. The moderating effect demonstrates that the positive effect of coach transformational leadership on cohesion could be enhanced when high levels of team trust are shared within the group. Implications for coach education and sport psychology in terms of theory and research are discussed.     

An exploration of the distractions inherent to social media use among athletes

Social media present athletes with a number of benefits and challenges. As a result, various sport stakeholders have debated appropriate social media use among athletes at major sport events, with some suggesting that using these platforms can have negative consequences. The purpose of this research was to examine the elements of social media that athletes perceive to be distracting during major sport events and the practices they undertake to address such distractions. Interviews with Australian elite athletes (N = 15) were conducted and data were analysed using thematic analysis. The findings reveal several elements associated with distraction, including positive and unwanted messages, branding pressures, and competitor content. Athletes reported two key practices that assisted in overcoming distractions, including switching off and handing over the control of their social media accounts. The findings extend distraction-conflict theory to athlete social media research, while presenting a preliminary conceptual model to assist researchers in further understanding the potential impact of social media distractions on athletes. Opportunities for sport practitioners to develop or implement social media education programs are described.     

The role of athlete narcissism in moderating the relationship between coaches' transformational leader behaviors and athlete motivation

Leadership research that examines follower characteristics as a potential moderator of leadership effectiveness is lacking. Within Bass's (1985) transformational leadership framework, we examined follower narcissism as a moderator of the coach behavior-coach effectiveness relationship. Youth athletes (male = 103, female = 106) from the Singapore Sports Academy (mean age = 14.28, SD = 1.40 years) completed the Differentiated Transformational Leadership Inventory (Callow, Smith, Hardy, Arthur, & Hardy, 2009), the Narcissistic Personality Inventory (Raskin & Terry, 1988), and indices of follower effort. Multilevel analyses revealed that athlete narcissism moderated the relationship between fostering acceptance of group goals and athlete effort and between high performance expectations and athlete effort. All the other transformational leader behaviors demonstrated main effects on follower effort, except for inspirational motivation.     

A multimethod examination of the relationship between coaching behavior and athletes' inherent self-talk

The aim of the present research was to investigate the relationship between coaching behavior and athletes' inherent self-talk (ST). Three studies were conducted. The first study tested the construct validity of the Coaching Behavior Questionnaire (CBQ) in the Greek language, and provided support for its original factor structure. The second study examined the relationships between coaching behavior and athletes' ST in field, with two different samples. The results showed that supportive coaching behavior was positively related to positive ST (in one sample) and negatively related to negative ST (in both samples), whereas negative coaching behavior was negatively related to positive ST (in one sample) and positively related to negative ST (in both samples). Finally, the third study examined the relationships experimentally, to produce evidence regarding the direction of causality. The results showed that variations in coaching behavior affected participants' ST. Overall, the results of the present investigation provided considerable evidence regarding the links between coaching behavior and athletes' ST and suggested that coaches may have an impact on athletes' thoughts.

The relationship between extension of the metatarsophalangeal joint and sprint time for 100 m Olympic athletes

Selected kinematic variables of the foot segments and the metatarsophalangeal (MTP) joint were investigated in relation to sprinting performance among 100 m sprint athletes at the 2000 Summer Olympic Games. It was hypothesized that the kinematics of the MTP joint, and forefoot and rearfoot segments, are related to sprint performance for both male and female athletes. Kinematic sagittal plane data were collected using two digital video cameras recording at 120 fields per second. It was determined that faster male sprinters experienced higher maximal rates of MTP extension, and faster female sprinters touch down with higher posterior sole angles and take off with lower posterior sole angles.
