【摘要】：本文通过采集6种核心稳定训练动作过程中的肌电信号,分析得出特定肌肉在不同动作下的疲劳状态。试验中,30名受试者完成6种核心稳定训练动作,分别是平板支撑、仰卧双桥、仰卧单桥(左、右侧交替)和两点交叉支撑(左、右侧交替),每种动作持续1 min,两种动作之间间隔2 min。测量肌肉为身体左、右侧的竖脊肌、腹外斜肌、腹直肌、股直肌、股二头肌、胫骨前肌和腓肠肌。采用中位频率的斜率值表征肌肉的疲劳状态,结果显示,在完成核心训练动作过程中仰卧双桥和仰卧单桥能引起竖脊肌更大的疲劳,平板支撑引起腓肠肌的疲劳度较大,而腹直肌的疲劳度在平板支撑与其它5种动作之间差异均具有统计学意义(P0.05);在6种核心稳定训练动作中,所测肌肉左、右侧疲劳度差异无统计学意义(P0.05)。本研究所得结论,为核心稳定训练动作针对不同肌肉块的训练效果提供了量化指导。
[Abstract]:In this paper, the electromyography (EMG) signals of six core stable training movements are collected, and the fatigue states of specific muscles under different actions are obtained.In the experiment, 30 subjects completed six kinds of core stable training movements, namely, flat support, supine double bridge, supine single bridge (left, right) and two points cross support (left, left).The right side alternates, each action lasts 1 minute, the interval between the two movements is 2 mins.The measured muscles were the vertical spinal muscle, the external oblique muscle, the rectus abdominis muscle, the rectus femoris muscle, the biceps femoris muscle, the anterior tibial muscle and the gastrocnemius muscle.Muscle fatigue was characterized by the slope value of median frequency. The results showed that supine double bridge and supine single bridge could cause greater fatigue of vertical spinal muscle, while plate support caused greater fatigue of gastrocnemius muscle.But the fatigue degree of the rectus abdominis muscle was significantly different between the plate support and the other five movements, but there was no significant difference in the fatigue degree between the left and the right side of the muscle in the six core stable training movements.The conclusion of this study provides quantitative guidance for the training effect of different muscle mass.
