In the first study, investigators looked at whether exercise training could activate progenitor cells — immature cells that can divide into other cells and help repair tissue. Fifty men with moderate-to-severe heart failure were randomized to receive either six months of exercise training under the supervision of a physician, or to be sent to a control group that remained inactive. At the end of six months, biopsies of the patients' thigh quadriceps revealed that the number of progenitor cells in the exercise group increased by 109 percent, progenitor cells turning into muscle cells increased by 166 percent, and progenitor cells actively dividing to form new cells and repair damage to the muscle increased sixfold. For the second study, 37 men with severe heart failure were randomly assigned to receive three months of exercise or to remain inactive. But regular exercise was linked to an average 35 percent increase in exercise capacity, giving the men about 75 percent of the capacity seen in healthy people of the same age.
