The overall purpose of this study was to examine stressors, coping strategies, and perceived coping effectiveness among professional rugby union players. Eight fi rst class professional male rugby union players maintained diaries over a 28-day period. The diaries included a stressor checklist, an open-ended coping response section, and a Likert-type scale evaluation of coping effectiveness. Total reported stressors and coping strategies were tallied and analyzed longitudinally. The most frequently cited stressors were injury concerns, mental errors, and physical errors. The most frequently cited coping strategies were increased concentration, blocking, positive reappraisal, and being focused on the task. The most effective coping strategies were focusing on task and increasing effort. Professional rugby players use a variety of different coping strategies in order to manage the stressors they experience, but the effectiveness of their coping attempts can vary.

We determined the effects of cold water immersion (CWI) on long-term adaptations and post-exercise molecular responses in skeletal muscle before and after resistance training. Sixteen men (22.9 ± 4.6 y; 85.1 ± 17.9 kg; mean ± SD) performed resistance training (3 day/wk) for 7 wk, with each session followed by either CWI [15 min at 10°C, CWI (COLD) group, n = 8] or passive recovery (15 min at 23°C, control group, n = 8). Exercise performance [one-repetition maximum (1-RM) leg press and bench press, countermovement jump, squat jump, and ballistic push-up], body composition (dual X-ray absorptiometry), and post-exercise (i.e., +1 and +48 h) molecular responses were assessed before and after training. Improvements in 1-RM leg press were similar between groups [130 ± 69 kg, pooled effect size (ES): 1.53 ± 90% confidence interval (CI) 0.49], whereas increases in type II muscle fiber cross-sectional area were attenuated with CWI (−1,959 ± 1,675 µM2 ; ES: −1.37 ± 0.99). Post-exercise mechanistic target of rapamycin complex 1 signaling (rps6 phosphorylation) was blunted for COLD at post-training (POST) +1 h (−0.4-fold, ES: −0.69 ± 0.86) and POST +48 h (−0.2-fold, ES: −1.33 ± 0.82), whereas basal protein degradation markers (FOX-O1 protein content) were increased (1.3-fold, ES: 2.17 ± 2.22). Training-induced increases in heat shock protein (HSP) 27 protein content were attenuated for COLD (−0.8-fold, ES: −0.94 ± 0.82), which also reduced total HSP72 protein content (−0.7-fold, ES: −0.79 ± 0.57). CWI blunted resistance training-induced muscle fiber hypertrophy, but not maximal strength, potentially via reduced skeletal muscle protein anabolism and increased catabolism. Post-exercise CWI should therefore be avoided if muscle hypertrophy is desired. NEW & NOTEWORTHY This study adds to existing evidence that post-exercise cold water immersion attenuates muscle fiber growth with resistance training, which is potentially mediated by attenuated post-exercise increases in markers of skeletal muscle anabolism coupled with increased catabolism and suggests that blunted muscle fiber growth with cold water immersion does not necessarily translate to impaired strength development.

Objective:To investigate the relationship between mental toughness, sport injury beliefs, pain, and adherence toward a sport injury rehabilitation program.Design:A prospective design was employed that evaluated adherence over the entire rehabilitation period.Participants:70 patients undertaking a sport injury rehabilitation program for a tendonitis related injury.Main Outcome Measures:Adherence was measured using self report measures of clinic and home based rehabilitation alongside attendance.Results:No association was found between mental toughness and coping appraisals, although high mentally tough individuals displayed more positive threat appraisals and were better able to cope with pain than their less mentally tough counterparts. Greater attendance at rehabilitation sessions was displayed by more mentally tough individuals; however, more positive behavior during clinic rehabilitation was characterized by low mental toughness.Conclusions:Despite the 0benefits of being mentally tough, sports medicine providers need to be aware that a high degree of mental toughness may have negative consequences upon rehabilitation behavior and subsequently recovery outcomes.

This study explored stress and coping in electronic sports (esports) athletes and the influence of mental toughness (MT), as defined by two prominent conceptualizations: the 4/6Cs and Mental Toughness Index (MTI) frameworks. Participants were 316 esports athletes, ranked in the top 40% of one of five major esports: Defense of the Ancients 2, League of Legends (LoL), Counter Strike: Global Offensive, Overwatch and Rainbow Six: Siege. Participants completed the MTI, Mental Toughness Questionnaire 6 (MTQ6), Stress Appraisal Measure, and Brief COPE inventory. Results showed that MT (via both MT frameworks) was associated with perceived control, and MTQ6 subscales were associated with stress intensity. Mental toughness (both frameworks) was associated with the selection of more problem-focused and emotion-focused coping strategies and less avoidance coping strategies. The results indicate there is some overlap between the MT and stress-coping process in high-performing traditional sports and competitive esports athletes. These results suggest that esports athletes could benefit from sports psychology interventions designed for traditional sports athletes. Finally, the MTQ6 and MTI had low shared variance (20%), suggesting that the two questionnaires appear to measure different aspects of MT.

The aims of the present study were twofold. First, to investigate self-reported social support, self-regulation, and psychological skill use in esports athletes (e-athletes) compared to traditional athletes. Second, to determine if self-reported social support, self-regulation, and psychological skill use influenced e-athlete in-game rank. An online survey was used to collect data from an international sample of e-athletes (n = 1,444). The e-athletes reported less social support, self-regulation, and psychological skill use than reported by traditional athletes in previous studies. E-athletes with higher scores in social support, self-regulation, and psychological skill use was associated with higher in-game rank. The lack of an organisational structure in esports may be a contributing factor as to why e-athletes score lower than traditional athletes on social support, self-regulation, and psychological skill use. Future research is warranted to explore the development of esports programs aiming to promote athletes’ social support, self-regulation, and use of psychological skills to enhance in-game performance and well-being.

Although physical activity participation has numerous physiological and psychological benefits, inactivity rates remain high, and a greater understanding of the factors that drive participation is needed. Growing evidence indicates that (1) the strength of individuals' social identification as a member of a particular physical activity group (e.g., an exercise group or sports team) is positively associated with their group-relevant participation, and (2) physical activity leaders (e.g., exercise group leaders, coaches, and captains) can foster members' identification, and thus their greater group-relevant participation. Extending previous crosssectional research, we examined relationships over time between sports group members' perceptions of their leaders' engagement in identity leadership, their group identification, and attendance. Participants (N = 186) from amateur sports teams completed measures of identity leadership, group identification, and attendance on two occasions, eight weeks apart. Lagged regressions indicated that perceptions of leaders' engagement in identity leadership at Time 1 predicted members' group identification at Time 2, controlling for their group identification at Time 1; and members' group identification at Time 2 was associated with their attendance at Time 2, controlling for their attendance at Time 1. Mediation analysis demonstrated a significant indirect effect of perceptions of leaders' engagement in identity leadership on group members' attendance through greater group identification. Findings provide evidence of the participation-related benefits of forming, and maintaining, strong social identities in physical activity settings, and point to the role leaders can play in fostering members' sustained identification and participation.
