STRENGTH INCREASES NEARLY 175 PERCENT: In one of two studies at the Tufts University Research Center, nine women and men, ages 87 to 101, strengthened their arms and legs by exercising with weight machines. In eight weeks, they increased the strength in the front thigh muscles by an average of almost 175 percent.
IMPRESSIVE RESULTS FOR WOMEN: The second Tufts study divided 40 postmenopausal women, none of whom were on hormone replacement therapy, into two groups, one that lifted weights and one that did not. The group that didn’t lift lost bone and muscle mass; the other group increased its average strength to the equivalent of women 15 to 20 years younger.
