The effects of anthropometry and pre-race experience on race performance were investigated in male nonprofessional ultra-runners performing a multistage run of 1,200 km over 17 days. Of 24 athletes examined pre-race, 14 (58%) dropped out during the race due to overuse injuries of the lower limbs. During the race, body mass, thickness of the calf skin-fold, skeletal muscle mass, and percent body fat decreased significantly, while circumference of the upper arm, thickness of triceps, and abdominal skin-fold as well as Body Mass Index decreased significantly in the finishers. Neither anthropometry nor pre-race experience and training volume nor previously finished races were associated with the race time of the finishers. In future studies of ultra-runners, the influence of psychological (cognitive and emotional) predictors on race outcome should be investigated.
在17天内完成1200公里多阶段跑步的男性非专业超级跑步者中，研究了人体测量学和赛前经验对比赛成绩的影响。在赛前检查的24名运动员中，有14名（58%）在比赛期间因下肢过度使用损伤而退出。比赛期间，体重、小腿皮褶厚度、骨骼肌质量和体脂百分比显著下降，而完成比赛者的上臂围、肱三头肌厚度、腹部皮褶以及身体质量指数显著下降。人体测量学、赛前经验、训练量以及之前完成的比赛均与完成比赛者的比赛时间无关。在未来对超级跑步者的研究中，应调查心理（认知和情绪）预测因素对比赛结果的影响。
