Background: Athletes, coaches, sport psychology practitioners, and researchers suggest that mental toughness represents an important construct that is associated with athletic performance. Unfortunately, the absence of real-world performance as a dependent variable has limited our ability to substantiate this claim. The concern of a lack of ecologically valid measures of sports performance might be addressed by examining the relationship between mental toughness and sports performance using a standardized measure of personal best(PB) triathlon time and a validated unidimensional measure of mental ***: Three hundred and sixteen triathletes completed the 8-item mental toughness index(MTI), reported their age, and provided a PB Olympic distance triathlon time and the total number of triathlons they had completed to date. Given that males are typically quicker than females, a standardized time was calculated by dividing the PB by the current Olympic record for gender; we also hypothesized that more experienced triathletes would report quicker PB times because of greater frequency and duration of training. Once we had controlled for gender and experience,we predicted that mental toughness would be negatively associated with triathlon time and the size of the relationship would be of a moderate ***: Results revealed small-to moderate-sized negative relationships between both completed number of triathlons and mental toughness with standardized PB ***: The hierarchical regression analysis showed that mental toughness provided a unique contribution to the variability in standardized Olympic triathlon PB after controlling for the total number of triathlons completed.

Pay or Nature？ The Relative Weights of Pecuniary Incentives and Course Conditions in IRONMAN Races

引用

Economics World 2018年第2期6卷 108-120页

作者： Joachim Prinz Phillip Becker University of Duisburg-Essen Duisburg Germany University of Paderbom Paderbom Germany

Most of the studies analyzing the effectiveness of a tournament compensation style use data from an athletic context because data on an individual＇s income and output are easily available. While the papers illustrate a positive correlation between the level of prize money doled out by the event organizer and athletes＇ performances the impact of pay on productivity might be biased if other fixed and random components are neglected and left out in the athlete＇s output function. The aim of this paper is to analyze this bias empirically by using new and detailed information from 62 long-distance triathlon IRONMAN competitions around the world to reassess the motivational aspect of prize money, controlling for course and weather conditions. The results of the OLS data analysis indicate the persistence of the incentive effect provided by remuneration but this effect is mitigated when nature is controlled for.

Prevalence of Disordered Eating among Non-elite Multisport Endurance Athletes

Journal of Sports Science 2018年第1期6卷 1-8页

The prevalence of concerns about food and body weight among non-elite multisport endurance athletes is unknown. This study aimed to evaluate the prevalence of symptoms and concerns related to disordered eating and their association with performance among 162 non-elite athletes involved in multisport endurance summer and winter events. Self-reported symptoms and concerns related to disordered eating were assessed using the Eating Attitudes Test-26 （EAT-26） questionnaire. The mean EAT-26 score （~ SEM） was 6.5 ~ 0.5 and only 9 athletes （5.6%） scored 20 arbitrary units or above. In multivariate regression stepwise analyses, the EAT-26 score （~ = 0.145, P = 0.0003） significantly predicted percent ranking. These findings suggest that the prevalence of self-reported symptoms of disordered eating is low among non-elite multisport endurance athletes. However, greater concerns regarding food intake and body weight may be associated with poorer performance even among non-elite athletes with normal BMI values and at the lower end of the EAT-26 score.
