The electromyographic activity of the biceps brachii--BB (long head), triceps brachii--TB (long head) and deltoideus--DA (clavicular portion) muscles, during the going (G) and return (R) phases in "front support" exercise, as well the efficacy of this exercise for the development of these muscles strength were studied in 10 male volunteers. The values were normalized through maximum voluntary isometric contraction (MVIC = 100%) and statistically analyzed using the Friedman, DMS and Wilcoxon non-parametric test. A value of p < or = 0.05 indicated significance (Campos, 1983). All the muscles presented higher electromyographic activity in the return phase of the movement. The triceps brachii was the muscle which had higher activity in both phases of the movement. It was concluded that the "front support" exercise is efficient for strength development mainly in the triceps brachii muscle.
在10名男性志愿者中，研究了肱二头肌（长头）、肱三头肌（长头）和三角肌（锁骨部）在“前支撑”运动的前进（G）和返回（R）阶段的肌电活动，以及该运动对这些肌肉力量发展的效果。通过最大自主等长收缩（MVIC = 100%）对数值进行归一化处理，并使用Friedman、DMS和Wilcoxon非参数检验进行统计分析。p≤0.05的值表示具有显著性（坎波斯，1983年）。所有肌肉在运动的返回阶段均呈现出更高的肌电活动。肱三头肌是在运动的两个阶段中活动都较高的肌肉。得出的结论是，“前支撑”运动主要对肱三头肌的力量发展有效。
