背景资料：调查的原因/S的肌肉疲劳经历了半铁距离triathlon.Methodology/主要调查结果：我们招募了25名训练有素的铁人三项运动员（36 +/- 7岁; 75.1 +/- 9.8公斤）的研究。在比赛前和比赛后，在力量平台上进行反向运动跳跃时测量跳跃高度和腿部肌肉功率输出，以确定腿部肌肉疲劳。在比赛前后还采集了体重、握力最大力量以及血液和尿液样本。结果：跳跃高度（30.3 ± 5.0 ~ 23.4 ± 6.4cm; P
Background: To investigate the cause/s of muscle fatigue experienced during a half-iron distance triathlon.Methodology/Principal Findings: We recruited 25 trained triathletes (36 +/- 7 yr; 75.1 +/- 9.8 kg) for the study. Before and just after the race, jump height and leg muscle power output were measured during a countermovement jump on a force platform to determine leg muscle fatigue. Body weight, handgrip maximal force and blood and urine samples were also obtained before and after the race. Blood myoglobin and creatine kinase concentrations were determined as markers of muscle damage.Results: Jump height (from 30.3 +/- 5.0 to 23.4 +/- 6.4 cm; P
