All subjects performed quadriceps maximal voluntary contraction ( MVC ) and fastest speed leg extension with different levels ( 75 % 60 % 45 % 1RM ) and 45 % fatigue test to all-out .
受试者实施股四头肌最大 等长 收缩、最快速度不同强度(75%、60%、45%1RM)的伸膝动作及45%的疲劳测试,记录向心期不同强度的MMG讯号。
Maximal voluntary contraction and peak torque increased significantly in the T group but did not change in the P group .
组中最大 自愿 收缩和最大扭矩显著增加,而P组没有改变。
Methods : EMG of 80 patients with PM and DM were analyzed including fibrillation mean duration of MUP mean amplitude of MUP polyphasic recruitment pattern of maximum voluntary contraction NCV and musele biopsies .
方法:分析80例多发性肌炎、皮肌炎患者肌电图检查中自发电活动,MUP时限、波幅及多相波,最大 随意 收缩时的募集形式,以及NCV检查及肌肉活检资料。

Every skeletal muscle maximal voluntary contraction ( MVC ) EMG were recorded to make the standardization . Each test complete at 4s and repeat 3 times . Record each experiment data of the electromyography trunk angles and COP and make the statistics and analysis .
记录每块测试肌的最大 自主 收缩(MVC)以做标准化处理,每次试验持续4s,重复3次,记录每次实验的肌电数据、躯干角和COP的数据,并作常规的统计、分析处理。
FES-induced movement and voluntary movement patterns were included in each contraction .
本研究设计了等角和等矩两种 收缩 状态,每种 状态包含FES诱发和 自主运动两种运动模式。
The motor unit active potentials disappeared during maximal voluntary contraction in 49 muscles and the recruitments decreased in 9 muscles .
49块肌肉 重 收缩时无运动单位电位,9块肌肉募集电位明显减小。
