Lower limb skin-fold thicknesses have been differentially associated with sex in elite runners. Front thigh and medial calf skin-fold appear to be related to 1,500m and 10,000m time in men but 400m time in women. The aim of the present study was to compare anthropometric and training characteristics in recreational female and male half-marathoners.
The association between both anthropometry and training characteristics and race time was investigated in 83 female and 147 male recreational half marathoners using bi- and multi-variate analyses.
In men, body fat percentage (β=0.6), running speed during training (β=-3.7), and body mass index (β=1.9) were related to half-marathon race time after multi-variate analysis. After exclusion of body mass index, r (2) decreased from 0.51 to 0.49, but body fat percentage (β=0.8) and running speed during training (β=-4.1) remained predictive. In women, body fat percentage (β=0.75) and speed during training (β=-6.5) were related to race time (r (2) =0.73). For women, the exclusion of body mass index had no consequence on the predictive variables for half-marathon race time.
To summarize, in both female and male recreational half-marathoners, both body fat percentage and running speed during training sessions were related to half-marathon race times when corrected with co-variates after multi-variate regression analyses.
在精英跑步运动员中，下肢皮肤褶皱厚度与性别存在差异关联。男性的大腿前侧和小腿内侧皮肤褶皱似乎与1500米和10000米跑的成绩有关，而女性的则与400米跑的成绩有关。本研究的目的是比较业余男女半程马拉松运动员的人体测量学和训练特征。
采用双变量和多变量分析，对83名女性和147名男性业余半程马拉松运动员的人体测量学、训练特征与比赛成绩之间的关联进行了研究。
在男性中，多变量分析后，体脂百分比（β = 0.6）、训练期间的跑步速度（β = -3.7）和体重指数（β = 1.9）与半程马拉松比赛成绩相关。排除体重指数后，r²从0.51降至0.49，但体脂百分比（β = 0.8）和训练期间的跑步速度（β = -4.1）仍具有预测性。在女性中，体脂百分比（β = 0.75）和训练期间的速度（β = -6.5）与比赛成绩相关（r² = 0.73）。对于女性而言，排除体重指数对半程马拉松比赛成绩的预测变量没有影响。
总之，在业余男女半程马拉松运动员中，多变量回归分析并用协变量校正后，训练期间的体脂百分比和跑步速度均与半程马拉松比赛成绩相关。
