The purpose of this study is to test influence of regular walking exercise using a Walking-Training Machine on the ability to recover from a perturbation. As a perturbation in the walking exercise, one of the training machine's two belts had it is speed reduced suddenly and at random. In experiment 1, the perturbation group was compared with the control group in order to show a clear effect. In experiments 2 and 3, the amelioration coefficient of the young group was compared with that of the elderly adults group using different methods. For experiments 2, the exercise walking speed was increased incrementally between groups, with the perturbation in the test being the same. For experiments 3, the exercise walking speed for each group was kept the same, with the perturbation intensity being increased. As a result, in experiment 1, the knee extensor maximal torque contraction time of improvement rate was high in the perturbation group. In experiment 2, the one-leg balance with eyes closed and the knee extensor muscles power amelioration was significant in the elderly adults group in comparison with the young group. In addition, is experiment 3, the one-leg balance with eyes open and the 10m maximum gait speed showed significant improvement in the elderly adults group. Improvement of body function was recognized by intervening in this exercise. The strengths and the speeds of the perturbations are important to canalize into postural control. It produced interaction in these elements to give irritation due to the perturbation in this walking exercise. Such strategies can adapt themselves to change in the environment flexibly. As a future experiment, it would be beneficial easy training to do dynamic balance practice at the time of walking.
