A multicenter pilot study found that structured physical activity improved physical functioning in sedentary elderly individuals. Participants who exercised regularly showed significant improvements in walking distance and reduced risk of major mobility disability.
A new study found that exercising regularly can lead to more effective weight loss than following a calorie-restricted diet, as exercise helps preserve muscle mass and improve aerobic capacity. Those who exercised lost between 9-10% of their body weight, while dieters lost 9-10%, but also experienced reduced muscle mass.
