Abstract
|
|
|
|
There were no significant differences in lumbar spine, femur and forearm BMD values among the three groups. However, the forearm BMD in the moderate activity group and low activity group groups were significantly different when the dominant hand and non-dominant hand were compared (p<0.05). In addition, walking, a form of weight-bearing exercise, is strongly recommended to improve bone health and prevent osteopenia in adolescents. Therefore we conclude that high amounts of daily walking could enhance the non-dominant hand BMD even though anatomically, the forearm bone is not a gravitational burden-bearing bone.
