To quantify the effect of unstable shoe wearing on muscle activity and haemodynamic response during standing.
Thirty volunteers were divided into 2 groups: the experimental group wore an unstable shoe for 8 weeks, while the control group used a conventional shoe for the same period. Muscle activity of the medial gastrocnemius, tibialis anterior, rectus femoris and biceps femoris and venous circulation were assessed in quiet standing with the unstable shoe and barefoot.
In the first measurement there was an increase in medial gastrocnemius activity in all volunteers while wearing the unstable shoe. On the other hand, after wearing the unstable shoe for eight weeks these differences were not verified. Venous return increased in subjects wearing the unstable shoe before and after training.
The unstable shoe produced changes in electromyographic characteristics which were advantageous for venous circulation even after training accommodation by the neuromuscular system.
定量研究不稳定鞋穿着对站立时肌肉活动和血液动力学反应的影响。
30 名志愿者被分为两组:实验组穿着不稳定鞋 8 周,而对照组在同一时期使用常规鞋。使用不稳定鞋和赤脚评估安静站立时内侧腓肠肌、胫骨前肌、股四头肌和肱二头肌的肌肉活动和静脉循环。
在第一次测量中,所有志愿者在穿着不稳定鞋时内侧腓肠肌活动增加。另一方面,在穿着不稳定鞋 8 周后,这些差异没有得到验证。静脉回流在穿着不稳定鞋的受试者训练前后都增加了。
即使在神经肌肉系统适应训练后,不稳定鞋也会引起肌电图特征的变化,这对静脉循环是有利的。
