초록

The purpose of this study was to investigate the impacts of body muscle mass and bone density on ability to ambulatory ability college students in adulthood instead of elderly. The subjects were University Student (N=34). muscle mass, Bone Density and Ambulatory Ability were measured in this study.
Measured parts of the body were 4 part of the leg, arm, trunk and whole body. Ambulatory Ability was measured during the 6-minute Walking Test.
The result indicated that arm muscle mass, leg muscle mass, trunk muscle mass, and whole body muscle mass of male students showed significant positive correlation (0.355~0.566) with walking distance (p<.05). However, it showed a significant correlation only in trunk bone mineral density among whole body mineral density (0.437, p<.05), and arm bone mineral density, leg bone mineral density, and whole body mineral density did not show any significant correlation. Maximum walking speed of male students did not show significant correlation with either muscle mass (0.029~0.140) or bone mineral density (0.091~0.306). In addition, among muscle mass of male college students, body muscle mass results were analyzed to be an important factor that can predict the walking distance from ambulatory ability by 32%.
In Conclusion, So far, muscle mass, muscle strength and bone density of elderly has been reported to affect the ambulatory ability. However, the conclusion of this study suggests that difference between body muscle mass also had a close relationship with the ambulatory ability of not only elderly but also college students in their adulthood as well. And it became clear that the whole body muscle mass is an important factor that can predict ambulatory ability among University students.
