Abstract

Thus paper purports to study AEMG(Averaged integrated EMG), muscle activity duration tine for the skilled group(four archers), unskilled group(three archers), and the beginner group(four archers), in order to analyze the upper bodies` EMG when they shoot. The instrument for measuring EMG is muscle tester ME3000P. Measured parts of muscles are right trapezius, biceps brachii, deltoid and latissmus dorsi. The following is the result according to the analysis of AEMG data and statistics. According to the results of AEMG between the groups, there was no difference for trapezius. As for biceps brachii and deltoid, the beginner group showed the higher value than the unskilled and skilled group. For latissmus dorsi, the skilled group showed the higher value than the unskilled and beginner groups. This revealed that the mere skilled group reduced the use of arm muscles and kept the stability of shooting and balance with the effective use of latissmus dorsi. According to the results of the muscle activity duration time, there was no difference between the groups for trapezius and latissmus dorsi. As for biceps brachii, the skilled group showed the shorter time than the unskilled and beginner groups. For deltoid, the skilled and unskilled groups showed the shorter time than the beginner group. The muscle activity duration time of trapezius and latissnnrs dorsi turned out to have no influence on shooting Biceps brachii showed the shorter limn and higher EMG and this made the effective shooting for the skilled group comparing with other groups. The amount of set up ∼ release`s muscle activity duration time is in the following order : beginner group, unskilled group, skilled group.
