Effect of exercise intensity on bone density, strength, and calcium turnover in older women

Article Abstract:

This study compares the effects of high-intensity strength training and a low-intensity walking program on bone density, calcium turnover, and muscle strength in older women. No significant group differences were found for bone density, but high-intensity training was significantly more effective in improving muscle strength.

The influence of direct supervision of resistance training on strength performance

Article Abstract:

This study examines the effects of supervision on the results of a heavy-resistance training program. Results indicate that directly supervised training resulted in significantly greater training loads, larger slope increases in bench presses, and greater gains in maximal strength when compared to an unsupervised control group.
