Pumped Up for Life

Seniors Riding BicyclesWith age, our skeletal muscles tend to lose mass and strength in a phenomenon known as sarcopenia.

Roger Fielding, director of the Nutrition, Exercise Physiology and Sarcopenia Laboratory at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts, points out that in aging populations, physical activity has been shown to retard muscle loss and maintain the ability to function. He recommends including one or two sessions of strength or resistance training per week, in addition to a regular daily regimen of aerobic activities such as walking, biking or swimming. “We really think exercise is a way to preserve independence in older adults,” he told the Boston Globe recently.
