Declining fitness was once expected at about age 35 – now we know it doesn’t have to.
Why grow old gracefully? Even though Ponce de Leon’s efforts to find the fountain of youth were futile, may individuals have continued his crusade.
Aging is a fact of life, and surprisingly, scientists do not know a great deal about this process. For most individuals, the celebration of their 35 birthday begins to mark the decline of physiological functions.
How your body changes
Increase in your fat storage with a reduction in muscle and bone mass results in an elevation in percentage of body fat. A large part of these changes can be accounted for by a less active lifestyle and a drop in basal metabolism. This means that fewer calories are required to maintain body weight, while at the same time, fewer calories are expended.
Decreases in reaction time can be observed under laboratory conditions, but you probably won’t notice this unless you are in your 50’s. This slowing is a result of decreases in nerve conduction velocities and an increase in the time required for the brain to process the information and to select the appropriate response.
The amount of blood your heart can pump per minute also declines along with an individual’s maximum breathing capacity. These factors explain why endurance capacity decreases.
Women are particularly prone to osteoporosis or the thinning of bones. This problem can begin as early as age 25, and speeds up as menopause is approached. It is during the first few years after menopause that the rate at which bone density is lost is tremendously accelerated.
Decreases in flexibility result from a loss of elasticity in the connective tissue. That’s one of the main reasons which explains why a person will experience initial joint stiffness after being idle ir remaining in a set position for a relatively short period of time.
The wearing away of the cartilage which attaches to the ends of the bones, will affect everyone sooner or later. Some evidence suggests that activities which demand repeated pounding, or those which require extremely heavy loads to be moved, place tremendous stress on the joints and ten to accelerate this process.
Exercise for youth
Before you give up all hope and flood the personnel department with requests information about early retirement, results of studies which compare sedentary and active people whose ages from 40-80 years old are encouraging.
The research suggests that you use it or lose it. Exercise strengthens the heart and reduces your risks of cardiovascular disease. Information does suggest that exercise can postpone the onset of normal age- related deterioration. Exercise improves blood flow to the brain.
Well-designed exercise programs are important for all individuals, but they take on even greater emphasis as one ages. The body is less forgiving when over-used and requires a longer period of time to fully recover from work.
Tailor your exercise program to meet your goals, make it fun!
