The existing literature often exhibits inconsistent findings regarding lower extremity kinetics during sloped running, likely due to high variability of typical individual joint moments between and within runners. A better understanding of the kinetic effects of sloped running may be achieved by comparing the support moment and joint contributions among level, upslope, and downslope running. Twenty recreational runners (10 females) ran on three different conditions (level, 6° upslope and 6° downslope). Total support moment and joint contributions of the hip, knee, and ankle joints were compared among the three slope conditions using a one-way ANOVA with repeated measures and post-hoc pairwise comparisons. Our results showed that peak total support moment was highest during upslope running and was lowest during downslope running. The joint contribution to total support moment was similar in upslope and level running where the ankle joint has highest contribution followed by the knee and hip joints. During downslope running, highest knee joint contribution but least ankle and hip joint contributions were found when compared to level and upslope running.
现有文献中关于倾斜跑步时下肢动力学的研究结果往往不一致,这可能是由于不同跑步者之间和内部典型关节力矩的高度变异性所致。通过比较水平、上坡和下坡跑步时的支撑力矩和关节贡献,可以更好地了解倾斜跑步的动力学影响。20 名休闲跑步者(10 名女性)在三种不同条件下(水平、6°上坡和 6°下坡)跑步。使用单向方差分析(重复测量和事后两两比较)比较三种坡度条件下的总支撑力矩和髋关节、膝关节和踝关节的关节贡献。我们的结果表明,在上坡跑步时,峰值总支撑力矩最高,在下坡跑步时最低。在上坡和水平跑步时,踝关节的贡献最高,其次是膝关节和髋关节,对总支撑力矩的贡献相似。与水平和上坡跑步相比,在下坡跑步时,膝关节的贡献最高,而踝关节和髋关节的贡献最小。
