The current study focused on the differences between male and female non-professional triathletes during a maximal incremental test on the cycle ergometer, as well as, the cycle and run portion of a simulated sprint triathlon. In addition, this research analysed the during association between cycle ergometer maximal incremental test and simulated race variables.
Fourteen recreational triathletes, 8 female (35.0 ± 8.1 years; 166.8 ± 7.2 cm; 69.4 ± 14.6 kg; 24.7 ± 3.2 kg.m-2) and 6 male (47.7 ± 14.3 years; 179.9 ± 8.6 cm; 77.8 ± 5.8 kg; 24.0 ± 1.3 kg.m-2) performed a maximal incremental test and a simulated sprint triathlon race (20 km cycle and 5 km run). No significant differences were found during maximal testing between groups, however, males obtained higher VO2max, Pmax, PVT1, PVT2 and VO2VT2 (p > 0.05, ES = -0.8 to -1.9, large) values than females. No differences between gender were observed during 5 km running during the simulated triathlon. Average and maximal speed (p < 0.05 y p < 0.01, ES = -1.3- -4.1, large) and average and maximal power) (p < 0.01, ES = -2.4- -2.8, alto) during the 20-km cycling were significantly lower in the female group, whereas, time to complete the 20 km (p < 0.01, ES = 1.6, alto) was significantly longer than the male triathletes.
Male triathletes who obtained greater values during the maximal test, presented a superior 20km cycling performance. Females who presented larger values during the maximal test accomplished superior performances during both cycling and running simulated tests. These results suggest that recreational male triathletes may present a greater performance during maximal cycle ergometer test and during 20 km cycling simulation than female and the association between a maximal incremental test and simulated triathlon performances might depend on the triathlete’s gender.
