McMaster University researchers studying the mystery of why some weightlifters’ muscles grow much more quickly than others’ have found new answers through a novel experiment in which subjects worked out one leg and immobilized the other. By comparing the genetic responses of the muscles to exercise, the research team identified a set of 141 genes that are involved in regulating skeletal muscle growth. The findings generate new knowledge in the fight against debilitating muscle loss in older adults.
