Physical Changes Associated With Aging
Most age-related biological functions peak at age 30 and begin to decline linearly after that (see table Some Age-Related Physiological Changes); this decrease can be significant during stressful situations but has little or no effect on daily activities. Therefore, more than the normal aging process, diseases are mainly responsible for losing function in old age.
In many cases, this deterioration associated with aging can be secondary at least in part to lifestyle, behavior, diet, and environment, and therefore can be altered. For example, aerobic exercise may prevent or partially reverse the decline in maximal exercise capacity (oxygen uptake per unit time or Vo2max), muscle strength, and glucose tolerance in healthy older people. Healthy but sedentary.
Regular Physical Activity
Only about 10% of older people participate in regular physical activity for> 30 minutes 5 times a week (usual recommendation). Between 35 and 45% practice a minimum of exercise. Seniors tend to be less active than other age groups for many reasons, the most common of which are illnesses that limit their physical activity.
The Benefits Of Physical Activity
The benefits of physical activity for the elderly are numerous and far outweigh the risks (e.g., falls, torn ligaments, muscle strains). The advantages are as follows
- Reduced death rates, even among smokers and obese people
- Preservation of skeletal aerobic capacity, muscle strength, and bone density, contributing to increased mobility and independence
- Reduced Risk Of Obesity
- Prevention and treatment of cardiovascular disease (including rehabilitation after a heart attack), diabetes, osteoporosis, colon cancer, and psychiatric illnesses (especially mood disorders)
- Prevention of falls and associated injuries through increased muscle strength, balance, coordination, joint function, and endurance
- Increased functional capacity
- Possibility of social interaction
- Greater sense of well-being
- Maybe better quality of sleep
Physical activity remains one of the few interventions that be able to restore lost physiological capacity.
The non-modifiable effects of aging may be less severe and more robust. Healthier aging can be achieved in many people. Today, people over 65 are more beneficial than their ancestors and stay that way longer.
