Abstract
The purpose of this study was to investigate the effect of high-intensity a nd low-intensity resistance training upon bone mineral density (BMD) by com paring the BMD of young male powerlifters (n = 5), recreational trainees (n = 5), and controls (n = 5). Lumbar spine (L2-L4), proximal femur, and whol e body BMDs were measured using dual-energy X-ray absorptiometry (DXA). The high-intensity group showed a significantly greater BMD when the whole bod y and trochanter regions were measured than the low-intensity and control g roup. The BMD of the lumbar spine, femoral neck, and Ward's triangle was gr eater in the high-intensity group compared with the control group. There wa s no significant BMD difference between the low-intensity and control group except at the trochanter region. These results suggest that high-intensity resistance training is effective for increasing BMD, but low-intensity res istance training is not.
