| Research Abstract |
Decrease in strength and atrophy of skeletal muscles with age hs been usually observed in elderly men and women. This may be due to the decreased walking ability of elderly people. It has not been clear, however, whether a cause-and-effect relationship exists between leg strength and walking ability. The purpose of the present study is to examine changes in walking style through the resistance training in elderly men and women. The nine subjects (4-male & 5-female, average 47 ye. old) who participated in this study were asked to do the resistance training for leg muscles for a period of 12 weeks. The measurements described below were carried out before and immediately after the training, to study the effects of the training. Isometric knee extension/flexion strength was measured by a Cybex machine. The style of normal walking in the sagittal plane was filmed using a video system (60 f/s). Hip, knee and ankle angles of the supporting leg were calculated in the following three phases in normal walking ; at the contact point of the heel (HC), at medium of the supporting phase (MID), and at the take-off point of the toe (TTO). Although the knee extension strength increased significantly (17%) by the training, the walking speed, the stride frequency and the stride length did not change. However, there are significant correlations between the increment of knee angles at TTO/HC phases in walking and the increment of knee extension strength. Thus, it was suggested from this result that the walking pattern involving an extended knee joint in supporting leg could be obtained by leg resistance training even in elderly men and women.
Furthermore, we have examined the basic experiment on the resistance training, and suggested the possibility of the resistance training in elderly men and women.
