背景资料：目前的研究的目的是确定是否执行俯卧撑运动的变化在一个不稳定的表面（瑞士球）的肩胛胸肌的肌电图振幅的影响相比，一个稳定的表面（Bench）.Methods：10名男性被招募从一个方便的样本的大学生。学生们在进行俯卧撑练习时，将脚或手分别放在长凳上和瑞士球上，记录了上腹肌、下腹肌、前锯肌和肱二头肌的肌电图。一个俯卧撑加运动也评估了与不同的支持surfaces.Results的手：有没有统计学上的显着差异（p < 0.05），平均肌电振幅的瑞士球相比，在板凳上进行相同的运动。肌肉活动的显着差异，在上肌和前锯肌作为结果的变化，在脚的位置相对于手的位置，而不管表面stability.Interpretation：在这项研究中使用的不稳定的表面是不是一个足够的条件来产生在选择肩胛胸和盂肱肌的肌肉活动增加在俯卧撑运动的变化。将脚抬高到手的上方似乎比增加瑞士球对肩部稳定肌肉组织幅度的影响更大。(C)2007爱思唯尔有限公司保留所有权利。
Background: The aim of the current study is to determine if performing push up exercise variations on an unstable surface (Swiss ball) influences EMG amplitude of the scapulothoracic muscles when compared with a stable surface (Bench).Methods: Ten males were recruited from a convenience sample of college students. Students eletromyograms were recorded from the upper trapezius, lower trapezius, serratus anterior and biceps brachii while performing push up exercises with the feet or hands placed on a bench and seperately on a Swiss ball. A push up plus exercise was also evaluted with hands on the different support surfaces.Results: There was no statistically significant (p < 0.05) difference in mean EMG amplitude on a Swiss ball when compared with the same exercise performed on a bench. Significant differences in muscle activity were seen in the upper trapezius and serratus anterior as a result of changes in foot position relative to hand position irrespective of surface stability.Interpretation: The unstable surface used in this study is not a sufficient condition to generate an increase in muscle activity in select scapulothoracic and glenohumeral muscles during push up exercise variations. Elevating the feet above the hands appeared to have a greater influence on shoulder stabilizing musculature amplitude than the addition of a Swiss ball. (C) 2007 Elsevier Ltd. All rights reserved.
