Objective: This study is aimed at estimating each muscle strength and EMG in flexion-extension and abduction-adduction motions while exercising the upper body and specifying the correlation between each agonist muscle activity and muscle strength. Method: Based on the previous studies, this research has selected the 10 upper- body muscles that are related to flexion-extension and abduction-adduction motions. Muscle strength and its activity have been measured during an experiment in synchronizing an Isokinetic dynamometer and an EMG. Pearson correlation coefficient has been used for an analysis about the correlation between the muscle strength and muscle activity. Results: 1. The agonists in flexion include: Upper Trapezius, Anterior deltoild, Middle deltoild, Biceps, Pectoralis major clavicular insertion. The agonists in extension include: Posterior deltoid, Tricep long, Infraspinatus, Latissimus Dorsi. The agonists in abduction include: : Upper Trapezius, Anterior deltoild, Middle deltoild, Biceps, Pectoralis major clavicular insertion. The agonists under adduction include: Tricep long, Pectoralis major sternal insertion, Latissimus Dorsi, Pectoralis major clavicular insertion. 2. The results of an analysis of correlation between muscle strength(Nm) and muscle activity(%MVC) in 4 motions(flexion, extension, abduction and adduction) were as follows: ① The result of flexion is significant correlation (acoefficient of correlation: 0.573**), ② The result of extension is weak correlation (0.387*), ③ The result of abduction is significant correlation (0.428*), ④ The result of adduction is significant correlation (0.693**). Conclusion: This research has analyzed the correlation between each agonist muscle activity and muscle strength in the four motions. The results between mean value of agonists" muscle activity and shoulder"s muscle strength showed significant correlation but the correlation between each agonist and muscle strength was not showed.
