Resumo

The purpose of this study was to verify the physiological and anthropometric determinants of triathlon performance in female and male athletes. This study included 40 triathletes (20 male and 20 female). Dual-energy X-ray absorptiometry (DEXA) was used to assess body composition, and an incremental cardiopulmonary test was used to assess physiological variables. A questionnaire about physical training habits was also completed by the athletes. Athletes competed in the Olympic-distance triathlon race. For the female group, the total race time can be predicted by V?O(2)max (beta = -131, t = -6.61, p < 0.001), lean mass (beta = -61.4, t = -2.66, p = 0.018), and triathlon experience (beta = -886.1, t = -3.01, p = 0.009) (r(2) = 0.825, p < 0.05). For the male group, the total race time can be predicted by maximal aerobic speed (beta = -294.1, t = -2.89, p = 0.010) and percentage of body fat (beta = 53.6, t = 2.20, p = 0.042) (r(2) = 0.578, p < 0.05). The variables that can predict the performance of men are not the same as those that can predict the triathlon performance of women. These data can help athletes and coaches develop performance-enhancing strategies. (AU)
