Clinically speaking, we begin to age from the moment of conception. As we approach our middle years, if our bodies are not well cared for, the effects of normal aging begin to become apparent. Various organs and systems begin to display deterioration. The effects of this deterioration present themselves as heart disease, arthritis, elevated blood pressure and low back problems to name a few. Other changes that occur include decreases in hormone production and elasticity begins to diminish in muscles, skin and blood vessels. Many of these adverse effects of aging can be reversed or slowed with the intervention of a proper and regular exercise routine. No matter how well one maintains oneself, the physiological process of aging will take its toll. Exercise does not stop the biological clock, but it can slow it considerably. Proper exercise is imperative in maximizing
physiological capacity.
Most researchers believe that the maximum life span in humans is slightly over 110 years. This life span has remained unchanged for 300 years in spite of tremendous advances in public health. Scientists suggest that we should not experience a steady decline in health starting in our 30s, but rather live successfully into our 80s before bodily systems start to break down.
Average life expectancy in the United States has increased dramatically in this century, from about 47 years in 1900 to about 75 years in 1990. This increase is mostly due to improvements in sanitation, the discovery of antibiotics, and advancements in medical care; but as scientists make headway against chronic diseases such as cancer and heart disease, some think it can be extended even further.
Maximum human life span seems to be another matter. There is no evidence that it has changed in thousands of years despite fabled fountains of youth and biblical tales of long-lived patriarchs. However, the dream of extending life span has shifted from legend to laboratory in recent years as more gerontologists than ever are exploring the genes, cells and organs involved in the aging process. With each passing day they uncover more secrets to healthy living and longevity. Physical activity is one of them.
According to a study done at Stanford University, longtime runners live longer lives and have less pain, disability and disease than their sedentary peers. The longtime runners in this study were leaner, needed less medication and had fewer joint problems than non-runners of the same age. This evidence is proof positive that living an active life is beneficial.
The past surgeon general has estimated that close to 85% of our most dreaded diseases could be prevented with appropriate lifestyle changes, including a good diet and regular exercise. Healthy lifestyles behaviors and sensible exercise would not only prevent disease and untimely death but would improve the quality of one’s life! No one wants to just survive; everyone wants to live fully. Regular exercise will foster that goal!
Being Sedentary Can Be Hazardous To Your Health
The following list includes information and facts regarding the adverse effects associated with physical inactivity.
Inactivity and poor diet cause at least 300,000 deaths a year in the United States.
Adults who are less active are at greater risk of dying of heart disease and developing diabetes, colon cancer and high blood pressure.
More than 60% of U.S. adults do not engage in the recommended amount of physical activity.
Approximately 40% of U.S. adults are not active at all.
Physical inactivity is more common among women than men, African American and Hispanic adults than whites, older than younger adults, and the less affluent than more affluent individuals.
Social support from family and friends is consistently and positively related to regular physical activity.
Inactivity increases with age. By age 75, about one in three men and one in two women engage in no physical activity.
People with disabilities are less likely to engage in regular moderate physical activity than people with no physical disabilities, yet they have similar needs to promote health and prevent lifestyle-related diseases.
