Physical activity and public health: a recommendation from the Centers for Disease Control and Prevention and the American College of Sports Medicine
Article Abstract:
Adults should engage in 30 minutes daily of moderate-intensity physical activity, according to recommendations released by the Centers for Disease Control and Prevention (CDC) and the American College of Sports Medicine. A committee composed of members of the CDC and the American College of Sports Medicine reviewed available medical information and concluded that daily moderate-intensity physical activity significantly reduces the risk of death from certain diseases including coronary heart disease, high blood pressure and colon cancer. The committee's research indicates that short bursts of physical activity can be accumulated during the day to reach the 30-minute total. Thirty minutes of moderate-intensity exercise is the equivalent of a brisk two-mile walk. Other activities that may contribute to the total amount of exercise include gardening, housework and active playing with children.

Moderate-intensity exercise and self-rated quality of sleep in older adults: a randomized controlled trial
Article Abstract:
Older adults who have trouble sleeping may benefit from a regular exercise program. Researchers randomly assigned 29 women and 14 men between the ages of 50 and 76 to moderate-intensity exercise or no exercise (the control group). The exercise consisted of brisk walking or low-impact aerobics 4 times a week for 30 or 40 minutes. After 16 weeks, those in the exercise group reported better quality sleep that lasted almost an hour longer and spent less time napping. They also fell asleep faster compared to their baseline value. Those in the control group experienced no change in sleep habits.
