The purpose of this study was to investigate the effect of anthropometric characteristics and training indices on marathon race times in recreational male marathoners.
Training and anthropometric characteristics were collected for a large cohort of recreational male runners (n = 126) participating in the Basel marathon in Switzerland between 2010 and 2011.
Among the parameters investigated, marathon performance time was found to be affected by mean running speed and the mean weekly distance run during the training period prior to the race and by body fat percentage. The effect of body fat percentage became significant as it exceeded a certain limiting value; for a relatively low body fat percentage, marathon performance time correlated only with training indices.
Marathon race time may be predicted (r = 0.81) for recreational male runners by the following equation: marathon race time (minutes) = 11.03 + 98.46 exp(-0.0053 mean weekly training distance [km/week]) + 0.387 mean training pace (sec/km) + 0.1 exp(0.23 body fat percentage [%]). The marathon race time results were valid over a range of 165-266 minutes.
本研究旨在调查人体测量特征和训练指标对男性业余马拉松运动员马拉松比赛成绩的影响。
收集了2010年至2011年期间参加瑞士巴塞尔马拉松赛的一大群男性业余跑步者（n = 126）的训练和人体测量特征数据。
在所调查的参数中，发现马拉松比赛成绩受平均跑步速度、比赛前训练期间的平均每周跑步距离以及体脂百分比的影响。当体脂百分比超过某个极限值时，其影响变得显著；对于相对较低的体脂百分比，马拉松比赛成绩仅与训练指标相关。
对于男性业余跑步者，马拉松比赛时间可以通过以下公式预测（r = 0.81）：马拉松比赛时间（分钟）= 11.03 + 98.46 exp（-0.0053平均每周训练距离[千米/周]）+ 0.387平均训练配速（秒/千米）+ 0.1 exp（0.23体脂百分比[％]）。马拉松比赛时间结果在165 - 266分钟范围内有效。
