The purpose of this study was to verify what major muscles are during field hockey scoop motion on recuritment during scoop motion. 16 middle. school students(male, female.) were participated in the exercise test. The subject were divided into two group;male(N=8) and female(N=8). Electromyogram test was analyzed muscle type on recruitment during scoop motion by surface electrode. major muscle was measured by Integrated EMG in pre-test while scoop motion 12 set. The results of this study as follows: male group on scoop motion showed that major muscle of upper limb was measured left brachi oradialis, left trapezeius, right brachi oradialis, left deltoid, and major muscle of lower limb was right rectus femoris. right gastrocnemius. female group on scoop motion showed that major muscle of upper limb was measured left brachi oradialis, left trapezeius, left biceps brachi, left deltoid, and major muscle of lower limb was right rctus femoris, right biceps femoris.
