The purpose of this study was to analyze the reaction of electromyogram of the right leg muscle as skaters glide around the curved course of the short track, and to find out more effective and proper use of the muscle to enhance their performance. In this study, selected were three male backup national athletes in skating among those who are taking exercises in B skating center in order to analyze the electromyogram of the right leg in skating the curved course. The conclusions were as follows: 1. For the maximum electromyogram analyzed in low-speed skating, muscular activities were high in the order of vastus medialis and vastus lateralis, and this was also true of the average electromyogram. 2. For the maximum electromyogram analyzed in high-speed, vastus lateralis showed higher muscular activities than vastus medialis, and the average electromyogram also revealed the same phenomenon. 3. For the maximum electromyogram ratio of high-speed skating to low-speed skating by muscle, the inside of gastrocnemius showed the highest increase with 3.55±2.49 times; hamstring, 1.87±0.56 times; gluteus maximus, 1.62±0.30 times; vastus lateralis, 1.57±0.15 times; vastus medialis, 1.43±0.16 times; the outside of gastrocnemius, 1.21±0.15 times; tibialis anterior, 1.06±0.02 times. 4. For the average electromyogram ratio of high-speed skating to low-speed skating by muscle, the inside of gastrocnemius showed the highest increase with 2.04±0.52 times; gluteus maximus, 1.99±0.24 times; vastus lateralis, 1.88±0.39 times; the outside of gastrocnemius, 1.86±0.14 times; vastus medialis, 1.83±0.37 times; hamstring, 1.80±0.41 times; tibialis anterior, 1.01±0.02 times.
