Previous research concluded that Triple Iron ultra-triathletes were close to runners in anthropometry. We assessed similarities in anthropometry between 64 Triple Iron triathletes who competed over 11.4 km swimming, 540 km cycling, and 126 km running versus 95 100-km ultra-marathoners. Variables of anthropometry such as body mass, body height, length and circumferences of limbs, skin-folds and body fat, and training such as volume and speed were compared between ultra-triathletes and ultra-runners. The Triple Iron triathletes completed their race distance within 2811 min. (SD=379) and the 100-km ultra-marathoners within 691 min. (SD=117). Triathletes were younger, had higher body mass, shorter legs, higher circumference of upper arm and thigh, lower sum of skin-folds, and lower percent body fat compared to runners. Weekly training volume was higher for triathletes, and weekly hours in running and weekly kilometres in running were higher for runners. In the Triple Iron ultra-triathletes, the sum of eight skin-folds correlated to total race time. The circumference of upper arm, the sum of eight skin-folds, and percent body fat correlated with time in the running section .42, .47, and .43, respectively. In the 100-km ultra-marathoners, the sum of eight skin-folds, the skin-fold thickness of thigh, percent body fat, weekly running hours, and weekly running kilometres correlated with race time .55, .40, .56, -.50, and -.51, respectively. However, in the triathletes, none of these training variables was significantly correlated with race time. In the ultra-marathoners, the sum of eight skin-folds, the skin-fold thickness of thigh, percent body fat, weekly running kilometres, and speed in running during training were related to race time (correlations of .55, .40, -.28, and -.51, respectively). Overall, the ultra-triathletes were not similar to ultra-runners in their anthropometric measures and training variables.
先前的研究得出结论，三重铁人三项运动员在人体测量学方面接近跑步者。我们评估了 64 名参加超过 11.4 公里游泳、540 公里自行车和 126 公里跑步的三重铁人三项运动员与 95 名 100 公里超级马拉松运动员之间在人体测量学方面的相似性。比较了超级铁人三项运动员和超级马拉松运动员之间的人体测量变量，如体重、身高、四肢长度和周长、皮褶和体脂以及训练量和速度。三重铁人三项运动员在 2811 分钟内完成了比赛距离（SD=379），100 公里超级马拉松运动员在 691 分钟内完成了比赛距离（SD=117）。与跑步者相比，铁人三项运动员更年轻，体重更大，腿更短，上臂和大腿周长更高，皮褶总和更低，体脂百分比更低。铁人三项运动员的每周训练量更高，跑步的每周小时数和每周公里数更高。在三重铁人三项运动员中，八个皮褶的总和与总比赛时间相关。上臂周长、八个皮褶的总和和体脂百分比与跑步部分的时间相关分别为.42、.47 和.43。在 100 公里超级马拉松运动员中，八个皮褶的总和、大腿皮褶厚度、体脂百分比、每周跑步小时数和每周跑步公里数与比赛时间相关分别为.55、.40、.56、-.50 和-.51。然而，在铁人三项运动员中，这些训练变量都与比赛时间没有显著相关。在超级马拉松运动员中，八个皮褶的总和、大腿皮褶厚度、体脂百分比、每周跑步公里数和训练期间跑步速度与比赛时间相关（相关系数分别为.55、.40、-.28 和-.51）。总体而言，超级铁人三项运动员在人体测量学指标和训练变量方面与超级马拉松运动员没有相似之处。
