The purpose of this investigation was to assess the effect of compression sleeves on muscle activation cost during locomotion. Twenty-two recreationally active men (age: 25 ± 3 years) ran on a treadmill at four different speeds (ordered sequence of 2.8, 3.3, 2.2, and 3.9 m/s). The tests were performed without (control situation, CON) and while wearing specially designed lower leg compression sleeves (SL). Myoelectric activity of five lower leg muscles (tibialis anterior, fibularis longus, lateral and medial head of gastrocnemius, and soleus) was captured using Surface EMG. To assess muscle activation cost, the cumulative muscle activity per distance travelled (CMAPD) of the CON and SL situations was determined. Repeated measures analyses of variance were performed separately for each muscle. The analyses revealed a reduced lower leg muscle activation cost with respect to test situation for SL for all muscles (p < 0.05, η > 0.18). The respective significant reductions of CMAPD values during SL ranged between 4% and 16% and were largest at 2.8 m/s. The findings presented point towards an improved muscle activation cost while wearing lower leg compression sleeves during locomotion that have potential to postpone muscle fatigue.
本研究旨在评估压缩套对运动中肌肉激活成本的影响。22 名有休闲运动经验的男性（年龄：25 ± 3 岁）在跑步机上以四种不同速度（2.8、3.3、2.2 和 3.9 m/s 的顺序进行测试）进行测试。测试在不穿（对照情况，CON）和穿特制小腿压缩套（SL）两种情况下进行。使用表面肌电图（Surface EMG）记录 5 条小腿肌肉（胫骨前肌、腓骨长肌、腓肠肌外侧头和内侧头、比目鱼肌）的肌电活动。为了评估肌肉激活成本，确定 CON 和 SL 情况下每单位距离的累积肌肉活动（CMAPD）。对每个肌肉分别进行重复测量方差分析。分析显示，与 CON 相比，所有肌肉在 SL 情况下的小腿肌肉激活成本降低（p < 0.05，η > 0.18）。在 SL 期间，CMAPD 值的相应显著降低范围在 4%到 16%之间，在 2.8 m/s 时最大。研究结果表明，在运动中穿小腿压缩套可以改善肌肉激活成本，从而有潜力推迟肌肉疲劳。
