Benefits of Exercise

Learning Outcomes

  • Identify the benefits of regular exercise, for both body and brain

Longevity

Exercise, even after age fifty, can add healthy, active years to one’s life. Studies continue to show that it’s never too late to start exercising and that even small improvements in physical fitness can significantly lower the risk of death. Simply walking regularly can prolong your life.

Moderately fit people—even if they smoke or have high blood pressure—have a lower mortality rate than the least fit. Resistance training, also known as strength training, is important because it’s the only form of exercise that can slow and even reverse the decline of muscle mass, bone density, and strength. Adding workouts that focus on speed and agility can be especially protective for older people. Flexibility exercises help reduce the stiffness and loss of balance that accompanies aging.

Avoiding Diabetes

Diabetes, particularly type 2, is reaching epidemic proportions throughout the world as more and more cultures adopt Western-style diets (which tend to be high in sugar and fat). Aerobic exercise is proving to have significant and particular benefits for people with both type 1 and type 2 diabetes; it increases sensitivity to insulin, lowers blood pressure, improves cholesterol levels, and decreases body fat. In fact, studies show that people who engage in regular, moderate aerobic exercise (e.g., brisk walking or biking) lower their risk for diabetes even if they do not lose weight. Anyone on insulin or who has complications from diabetes should get advice from a physician before embarking on a workout program.
