Abstract

|
|
The Purpose of this study was ta investigate the change of bone density by Partial weight bearing and non-weight bearing exercise. Twelve female volunteers in good health (between 20 and 30 years of age) were studied as subjects. Subjects were divided into three groups; an experimental group 1(n =4 swimming group), group 2(n = 4 bicycle group) and control group=4. Before and after 11weeks(five times a week), the subjects were examined for change of bond density using a dual energy X-ray absorptiometry. The results were summarized as fellows T . There was increase in bone density of femoral neck in the group that swam but there was no difference in lumbar, femoral neck and femoral ward’’s triangle region (P<0.05) 2. There was increase in hone density of femoral ward’’s triangle in the group that swam but there was no difference in lumbar, femoral neck and femoral ward’’s triangle region(P<0.05) 3. After a aerobic exercise by partial weight bearing and non-weight bearing , there was no difference in the part of excessive muscle’’s exercise but there is the increase of the bone density in figures.
