Abstract
The purpose of this investigation was to compare sexes for time to fatigue at 100% VO2peak in recreationally trained individuals. Ten men (age: 23.4 +/- 1.8; height: 177 +/- 6.7; body mass: 83.8 +/- 11.3; +/- SD) and nine women (age: 25.0 +/- 2.5; height: 165.6 +/- 5.5; body mass: 62.7 +/- 6.7) participated in this investigation after providing written consent. One week after assessing VO2peak, subjects exercised on an electrically braked cycle ergometer at 100 percent of VO2peak until fatigue. The time taken to fatigue was 48.9 percent longer for men than women (274 +/- 13s vs. 184 +/- 14s; p < 0.001, for men and women, respectively). When normalized for fat free mass (ffm; s/kg ffm) no significant differences between men and women were observed (3.99 +/- 0.21s/kg ffm vs. 3.72 +/- 0.28s/kg ffm for men and women, respectively, p = 0.431). The difference in fatigability between the sexes at this exercise intensity is to a large degree related to the difference in fat free mass. Verf.-Referat
