초록
The purpose of this study was to investigate exercise intensity of TRX and each muscles by comparing muscle activity occurred through resistance training and TRX. The exercise of this study consisted of the upper body(bench press, low row), lower body(squat, leg curl) and abdominal muscle(crunch) using TRX and weight machine. In exercises for upper body, the TRX chest press with descending phase showed significantly higher triceps brachii muscle than 80%/1RM the bench press with same phase conducted on the flat ground. There was no difference of the muscle activity between seated row and TRX low row. In exercises for lower limb, 80%/1RM squat with ascending and descending phase showed significantly greater rectus femoris, vestus lateralis, and vestus medialis muscle activities than TRX squat. There was no difference of the muscle activities between leg curl row and TRX leg curl. In exercises for abdominal muscles, there was no difference of the muscle activities between crunch and TRX crunch. There is significant difference between the TRX squat and 80%/1RM squat. However, the other muscle activity was not significantly different between TRX and weight machine exercise. It shows that TRX is not only effective for core muscle strength, but also upper and lower body strength. But performing TRX squat that it makes little instability, it needs to be modified into alternate conformation such as one leg squat increasing instability much more.
