Squat was the most representative exercise for effective muscle development because it strengthens hip, thigh, and core muscle that are important for running, jump, and lift motion. The aim of this study was to investigate how leg stance types in squat exercise affect muscle activity, ground reaction force(GRF) and knee pain scale. Twelve weight lifters performed squat exercise with 0°, 15° and 45° leg angle 85% of 1RM. To yield the factor, we utilize force platform, electromyography(EMG) and display equipment and select eight kinds of muscles(rectus femoris, vastus lateralis, vastus medialis, glutus maximus, biceps femoris, semitendinosus, lumbar erector spinae). As a result of this study, there was not significant difference in muscle activity and GRF factor. However, muscle activity is inclined to be high and it takes the shortest time for GRF maximum impulse at 15° stance angle. Also, the degree of knee pain scale is the lowest at 15° stance angle. According to these results, 15° stance angle in squat exercise may be the most efficient form
