Many people routinely have a routine in which they exercise once a week. They should be performed along with the purpose of the training. Stability training is often carried out for enhancement of performance in the field of sports. An appropriate load is important for athletic rehabilitation. Rehabilitation without gradual advancement characteristics can lead to various repercussions such as prolongation of period of return to play and recurrence injuries. It is therefore advisable to objectively assess the load exerted by each training method. However, the degree of alteration of muscle activity on change of the height and instability of feet on performing side bridges was unclear. Seventeen healthy male participants performed four kinds of side bridges (on the stable floor, stable 30cm stand, unstable floor, unstable 30cm stand). Muscle activity was measured and inspected at the time of the enforcement. Activity of the gluteus medius, external oblique muscle, internal oblique muscle and the multifidus lumborum muscle were measured with the help of a surface electromyogram. The gluteus medius significantly showed low activity on the stable 30cm stand in com-parison with the other conditions. The external oblique muscle, internal oblique muscle, and the multifidus lumborum muscle significantly showed significantly high activity underon the unstable condition. It was thought that by raising the feet on the platform, the activity of the gluteus medius muscle decreased. Besides, it was suggested that the activity of the trunk muscles mayight be markedly required highly needed underon the unstable condition.
