Reasons why you can advise old ages to engage in exercise workout
Exercise and physical activity are great ways to feel better, boost your health and have fun. For most healthy adults, it is recommended that:
•At least 150 minutes a week of moderate aerobic activity or 75 minutes a week of vigorous aerobic activity, or a combination of moderate and vigorous activity. The guidelines suggest that you spread this exercise throughout the week. Examples include running, walking or swimming. Even small amounts of physical activity are helpful, and accumulated activity throughout the day adds up to provide health benefits.
•Strength training exercises for all major muscle groups at least two times a week. Examples include lifting free weights, using weight machines or doing body-weight training.
Some of the many benefits of regular exercise for older people include:
*Bone* – bone density begins to decline after the age of 40, but this loss accelerates around the age of 50 years. As a result of this bone loss, older people are more prone to bone fractures. Exercise may help to reduce the risk of bone loss and osteoporosis. Weight-bearing exercise, in particular, helps to keep bones healthy and strong.
*Heart and lungs* – moderate intensity exercise is most favourable: for example, exercising at about 70 per cent of the individual’s maximum heart rate (220 beats per minute minus your age). Studies show that cardiorespiratory fitness takes longer to achieve in an older person than a young person, but the physical benefits are similar. Regardless of age, people are able to improve their cardiorespiratory fitness through regular exercise.
*Muscle* – There is evidence to suggest that these changes are related to a sedentary lifestyle, rather than age. Muscle mass can increase in the older person after regularly exercising for a relatively short period of time.
*Joints* – the joints of the body require regular movement to remain supple and healthy. In particular, people with arthritis can benefit from aerobic and strengthening exercise programs.
Remember to check with your doctor before starting a new exercise program, especially if you have any concerns about your fitness, haven’t exercised for a long time, have chronic health problems, such as heart disease, diabetes or arthritis.
*Body fat levels* – carrying too much body fat has been associated with a range of diseases including cardiovascular disease and diabetes. Regular exercise burns kilojoules, increases muscle mass and speeds the metabolism. Together, these physiological changes help an older person maintain an appropriate weight for their height and build.
