The physical activity recommendation for older adults is similar to the recommendations from the American College of Sports Medicine and the American Heart Association for the general public. These recommendations include getting 30 minutes of exercise five days per week. The recommendations differ in that older adults need activities that increase flexibility, improve balance and increase heart rate through moderate-intensity aerobic activities such as water aerobics.
Population
The U.S. Bureau of the Census reports that the 2010 population of adults older than the age of 65 will double from 40 million to 80 million by the year 2040. This increase of older adults has led to a greater number of active older adults. This increase in activity has led to a number of studies to determine the effects of physical activity on older adults.
Water Aerobics
Water aerobics is a form of exercise that takes place in a pool or body of water. Participants can choose from shallow- or deep-water aerobics. Water aerobic classes consist of a warm up, aerobic workout, taper and a cool-down period. The main piece of equipment in water aerobics is your body. The water provides resistance as you move your body.
Benefits
The benefits of water aerobics include minimized stress on joints and back, reduced impact while jumping, there is no age barrier, overweight individuals can easily exercise and endurance is increased as the lungs and heart are strengthened. Other benefits include reduction of arthritis, lower risk of cancer, improved mental health and a lower risk of heart disease.
Warnings
Physical activity should be encouraged in old age because it results in a higher level of function and survival, however as with all exercise programs it is important to check with your doctor before beginning. Older adults have a greater risk of heart disease or other illnesses which may affect the type of exercise program that is suitable for you.
