Research Abstract	This study examined that the effect of exercise intensity and duration on energy metabolism in muscles that are not directly involved in exercise (so-called nonexercising muscle) during aerobic exercise by using near-infrered spectroscopy. Moreover this study examined whether walking at moderate intensity has an effect on increasing energy metabolism in nonexercising muscle. This study indicated that the energy metabolism in nonexercising muscle significantly increased 15-20 minutes after the beginning of exercise and that higher intensity exercise produced a larger increased in energy metabolism in nonexercising muscle during exercise. In addition, this study indicated that walking increased energy metabolism in nonexercising muscle to 1.3 fold over resting value. These findings of this study were considered to potentially provide new viewpoints about exercise prescription.
