Twenty-three recreational triathletes, 16 male and 7 female (mean = 21.7 yrs), performed max tethered swim (TS), cycle ergometer (CE), and treadmill run (TR) tests prior to participation in a competitive triathlon (0.91 km swim, 40 km cycle, 10 km run). The VO2max values on the TS, CE and TR were similar to those reported for trained athletes in each sport. As a group, cycling times were significantly correlated to both absolute (p less than 0.01) and relative (p less than 0.001) cycling VO2max (r = -0.57 and r = -0.78, respectively); running times significantly correlated with relative (p less than 0.001, r = -0.84) but not absolute (p greater than 0.05) running VO2max; and swimming times significantly correlated with absolute (p less than 0.01, r = -0.49) but not relative (p greater than 0.05) swimming VO2max. With the exception of absolute swim VO2max, the total performance times were significantly correlated to all VO2max values when expressed in both absolute and relative values. This study indicates the important role a moderately trained individual's aerobic power has in determining performances in endurance events such as the triathlon.
23名业余铁人三项运动员,16名男性和7名女性(平均年龄 = 21.7岁),在参加一场竞技铁人三项赛(0.91公里游泳、40公里自行车、10公里跑步)之前,进行了最大束缚游泳(TS)、自行车测功仪(CE)和跑步机跑步(TR)测试。TS、CE和TR上的最大摄氧量值与每项运动中训练有素的运动员所报告的值相似。作为一个整体,骑行时间与绝对骑行最大摄氧量(p < 0.01)和相对骑行最大摄氧量(p < 0.001)均显著相关(r分别为 -0.57和 -0.78);跑步时间与相对跑步最大摄氧量显著相关(p < 0.001,r = -0.84),但与绝对跑步最大摄氧量不相关(p > 0.05);游泳时间与绝对游泳最大摄氧量显著相关(p < 0.01,r = -0.49),但与相对游泳最大摄氧量不相关(p > 0.05)。除了绝对游泳最大摄氧量外,当以绝对值和相对值表示时,总比赛时间与所有最大摄氧量值均显著相关。这项研究表明,适度训练个体的有氧能力在决定耐力项目(如铁人三项)的表现中起着重要作用。
