The current study investigated the effects of shoes of different weights on calf individual muscle contributions during a running cycle. Twenty male runners ran on a force platform with shoes of four different weights (175 g, 255 g, 335 g, and 415 g). The study evaluated runners' lower extremity muscle forces under the four shoe weight conditions using a musculoskeletal modeling system. The system generates equality and inequality constraint equations to simulate muscle forces. The individual muscle contributions in each calf were determined using these muscle forces. Data were compared using one-way repeated-measure ANOVA. The results revealed significant differences in the contributions of the gastrocnemius lateralis. Post hoc comparisons revealed that running in the 175 g shoes resulted in a larger contribution of the gastrocnemius lateralis than running in the 415 g shoes during the braking phase. Therefore, wearing lightweight shoes while running may promote fatigue in the gastrocnemius muscle during the braking phase. The calf muscle activation results may indicate that an adaptation period is warranted when changing from heavy to lightweight shoes.
本研究旨在探讨不同重量的鞋子对跑步周期中小腿各肌肉贡献的影响。二十名男性跑步者在带有四种不同重量鞋子（175g、255g、335g 和 415g）的力台上进行跑步。该研究使用肌肉骨骼建模系统评估了跑步者在这四种鞋重条件下下肢肌肉的受力情况。系统生成等式和不等式约束方程来模拟肌肉受力。利用这些肌肉力量确定了小腿各肌肉的贡献。使用单向重复测量方差分析进行数据比较。结果显示，外侧比目鱼肌的贡献存在显著差异。事后比较表明，在制动阶段，穿着 175g 鞋子跑步比穿着 415g 鞋子跑步时外侧比目鱼肌的贡献更大。因此，跑步时穿轻便的鞋子可能会导致在制动阶段比目鱼肌疲劳。小腿肌肉激活结果表明，从重鞋换到轻鞋时需要适应期。
