Athletes' perceptions of coaching effectiveness and athlete-related outcomes in rugby union: An investigation based on the coaching efficacy model

This study examined the relationships between athletes' perceptions of coaching effectiveness, based on the coaching efficacy model, and their effort, commitment, enjoyment, self-efficacy, and prosocial and antisocial behavior in rugby union. Participants were 166 adult male rugby-union players (M age = 26.5, SD = 8.5 years), who completed questionnaires measuring their perceptions of four dimensions of coaching effectiveness as well as their effort, commitment, enjoyment, self-efficacy, and prosocial and antisocial behavior. Regression analyses, controlling for rugby experience, revealed that athletes' perceptions of motivation effectiveness predicted effort, commitment, and enjoyment. Further, perceptions of technique effectiveness predicted self-efficacy, while perceptions of character-building effectiveness predicted prosocial behavior. None of the perceived coaching effectiveness dimensions were related to antisocial behavior. In conclusion, athletes' evaluations of their coach's ability to motivate, provide instruction, and instill an attitude of fair play in his athletes have important implications for the variables measured in this study

Moral values and moral identity moderate the indirect relationship between sport supplement use and doping use via sport supplement beliefs

The Incremental Model of Doping Behaviour suggests doping grows out of the habitual use of performance-enhancing methods (e.g., sport supplements) and belief that they are necessary for performance. Importantly, in this model, doping is viewed as functional rather than moral choice. In two studies, we examined whether sport supplement use was indirectly related to doping use via sport supplement beliefs, and whether personal morality moderated this relationship. Competitive athletes (Study 1, N = 366; Study 2, N = 200) completed measures of supplement use, beliefs, and doping use. They also completed measures of moral values (Study 1) and moral identity (Study 2). In both studies, supplement use was indirectly related to doping use via beliefs. Moreover, this indirect relationship was moderated by moral values (Study 1) and moral identity (Study 2). That is, the relationship between supplement use and doping use via beliefs was negated when moral values and moral identity were high but not when they were low or moderate. Taken together, our findings suggest that sport supplement users, who believe they are necessary, are more likely to dope if they have low moral values and believe that being a moral person is unimportant to their self-image

Ego orientation is related to doping likelihood via sport supplement use and sport supplement beliefs

A growing body of evidence suggests sport supplement use is positively related to doping likelihood, both directly and indirectly via beliefs that sport supplements are effective for improving performance. However, it is unclear what leads an athlete to use sport supplements and whether such factors play a role in the supplement-beliefs-doping relationship. To address this issue, we examined whether motivational goal orientations were related to doping likelihood directly and indirectly via sport supplement use and sport supplement beliefs. Competitive athletes (  = 362, 39% female, mean ± SD; age = 23.6 ± 10.3 years, hours per week training = 5.8 ± 2.1, years competing = 5.8 ± 5.4) from a range of sports (e.g., athletics, soccer, weightlifting) completed an online survey measuring task and ego goal orientation, sport supplement use, sport supplement beliefs, and doping likelihood. Results indicated that ego orientation, but not task orientation, was indirectly related to doping likelihood via sport supplement use and sport supplement beliefs. This suggests that athletes who are ego oriented are more likely to use supplements, believe supplements are effective, and dope. These data suggest that researchers should consider ego goal orientations when interpreting relationships between sport supplement use and doping likelihood

The quiet eye effect:a test of the visual and postural-kinematic hypotheses

The quiet eye effect describes the performance advantage associated with a long ocular fixation on a critical target of an action, prior to and during movement execution. Researchers have advocated a multi-measure approach to shed light on the mechanism(s) behind the association between ocular activity and motor performance. In this study we used psychophysiological methods to test whether the quiet eye period is associated with enhanced visual processing (visual hypothesis) or longer movement durations (postural-kinematic hypothesis). Thirty-two recreational golfers putted 20 balls to a 2-m distant target on a flat surface. We examined quiet eye duration and time-varying eye quietness using electrooculography, occipital alpha power using electroencephalography, and swing duration using kinematic sensors. Occipital alpha power, an inverse neural marker of visual processing, increased prior to and during swing execution, suggesting decreased visual processing compared to baseline. Correlations revealed that, despite the overall decrease, visual processing decreased less with a longer quiet eye and greater eye quietness. Importantly, swing duration was strongly and positively correlated with both indices of ocular activity: longer quiet eye and greater eye quietness were associated with longer swing duration. Our findings support the postural-kinematic hypothesis, confirming that the duration of the quiet eye is associated with a slow movement execution and question the role of visual processing in the final moments of closed-loop aiming tasks. We anticipate major advancements in the mechanistic understanding of the quiet eye effect as researchers adopt psychophysiological methods to examine eye movements in combination with measures of other biological systems. <br/

Coaching efficacy and coaching effectiveness: examining their predictors and comparing coaches' and athletes' reports

Research on the conceptual model of coaching efficacy (Feltz, Chase, Moritz, & Sullivan, 1999) has increased dramatically over the past few years. Utilizing this model as the guiding framework, the current study examined: (a) coaching experience and sex as predictors of coaches' coaching efficacy; (b) sport experience, sex, and the match/mismatch in sex between coach and athlete as predictors of athletes' perceptions of their coach's effectiveness on the four coaching efficacy domains; and (c) whether coaches' reports of coaching efficacy and athletes' perceptions of coaching effectiveness differed. Coaches (N = 26) and their athletes (N = 291) from 8 individual and 7 team sports drawn from British university teams (N = 26) participated in the study. Coaches completed the Coaching Efficacy Scale (CES), while athletes evaluated their coach's effectiveness using an adapted version of the CES; coaches and athletes also responded to demographic questions. Results indicated that, in coaches, years of coaching experience positively predicted technique coaching efficacy, and males reported higher game strategy efficacy than females. In athletes, sport experience negatively predicted all perceived coaching effectiveness dimensions, and the mismatch in sex between athletes and their coach negatively predicted perceived motivation and character building coaching effectiveness. Finally, on average, coaches' ratings of coaching efficacy were significantly higher than their athletes' ratings of coaching effectiveness on A dimensions. The findings are discussed in terms of their implications for coaching effectiveness

Life events and acute cardiovascular reactions to mental stress: a cohort study

Objective: This study addressed the issue of whether frequent exposure to life events is associated with aggravation or blunting of cardiovascular reactions to acute mental stress. Methods: In a substantial cohort of 585 healthy young adults, systolic and diastolic blood pressure and pulse rate were recorded at rest and in response to a mental arithmetic stress task. Participants indicated, from a list of 50 events, those they had experienced in the last year. Results: There was an overall association between life events and blunted cardiovascular reactivity that was driven by variations in the frequency of exposure to desirable events. The total number of events and the number of personal events were negatively associated with systolic blood pressure and pulse rate reactions to acute stress, whereas the number of work-related events was negatively associated with diastolic blood pressure and pulse rate reactivity. The negative association between total events and systolic blood pressure reactivity was stronger for women than men, whereas men exposed to frequent undesirable events showed enhanced diastolic blood pressure reactivity. The blunting of pulse rate reactivity associated with frequent personal life events was evident particularly for those who had a relatively large number of close friends. Conclusions: The nature and extent of the association between life events exposure and stress reactivity in young adults depends on the valence of the events together with the sex of the individual and their social network size

The association between life events, social support, and antibody status following thymus-dependent and thymus-independent vaccinations in healthy young adults

This study determined whether stressful life events and social support were related to antibody status following both thymus-dependent and thymus-independent vaccinations. Life events in the previous year and customary social support were measured in 57 healthy students at baseline. Antibody status was also assessed at baseline and at five weeks and five months following vaccination with the trivalent influenza vaccine and the meningococcal A+C polysaccharide vaccine. Taking into account baseline antibody titre, high life events scores prior to vaccination were associated with lower responses to the B/Shangdong influenza strain at both five weeks and five months and meningococcal C at five weeks. Life events scores were not associated with response to the other two influenza viral strains nor response to meningococcal A. Those with high social support scores had stronger 5-week and 5-month antibody responses to the A/Panama influenza strain, but not to any of the other strains. These associations could not be accounted for by demographic or health behaviour factors, and also emerged from analyses comparing those who exhibited a four-fold increase in antibody titre from baseline with those who did not. Life events and social support were related to antibody status following influenza vaccination in distinctive ways that may be partly determined by vaccine novelty and prior naturalistic exposure. Life events also predicted poor antibody response to meningococcal C polysaccharide vaccination after previous meningococcal C conjugate vaccination. Neither psychosocial factor was associated with response to primary meningococcal A polysaccharide vaccination
