| 摘 要： | 目的:观察阻力训练和超等长阻力训练后下肢肌肉力量变化,比较肌肉激活模式的不同.方法:将16名男性篮球运动员随机分成两组,分别实施8周下肢阻力训练和超等长阻力训练.采用3-D测力台测试训练前、后最大随意收缩值,用表面肌电记录训练前、后6次重复训练动作的胫骨前肌、腓肠肌外侧头、股直肌、股外侧肌、股二头肌的激活信号,计算积分肌电值和髋、膝、踝关节周围拮抗肌共激活.结果:两组下肢肌肉力量均显著提高,阻力训练组效果较明显.超等长阻力训练组肌肉活性显著高于阻力训练组.训练后超等长阻力训练组肌肉活性出现适应性变化,髋、踝关节拮抗肌共激活显著升高,膝关节拮抗肌共激活训练前、后没有显著性差异.阻力训练组训练前、后肌肉活性及拮抗肌共激活没有显著变化.结论:超等长阻力训练有助于提高肌肉间协调性,可以优化肌肉动作的运动策略.

| Abstract: | Objective:The purpose of this study was to assess the changes of muscular strength and activity pattern after resistance and plyometric weight training.Methods:Sixteen healthy male basketball athletes were randomly divided into either the resistance(RT) or plyometric weight training(PWT) protocols,maximal voluntary contraction(MVC)were evaluated using 3-D force plate before and after 8-week training program.Muscular activity signals were recorded by surface electromyography(SEMG) from tibialis anterior(TA),... |
