Aging And Fitness Paper

I chose to do my research paper on Aging and Fitness. I choose this because I am an active person along with my fiancé and would like to find out the effects of staying active while you age. I’ve heard if you stay fit, you live longer. Is this really true? I want to know if it is how much longer a person can live versus a person who does not get much physical activity. Aging and Fitness is related to human aging in general through many ways. Regular exercise helps prevent the risk of disease and also keeps a person mobile. Since disease and immobility leads too often to death in older people, staying active helps a person live a longer life.
It 's never too late to start exercising. By being physically active, elderly people have
Once started, the benefits of exercise will be noticed, including improved sleep and self-esteem. Exercise and physical activity can improve or maintain your strength and fitness, make it easier to do the things you want to do, help your balance and walking, help with feelings of depression or anxiety and improve your mood, maintain your thinking skills (cognitive function) as you get older, prevent or treat diseases such as diabetes, heart disease, high blood pressure, breast and colon cancer, and osteoporosis ("Exercise and age,"
A study done by the Arthritis Foundation have suggested that dysfunction of mitochondria, the “powerhouse” of the cell, is involved in the loss of muscle mass and functional impairment commonly seen in older people. Studies have shown that in older adults, there is a decline in mitochondrial function with age. A group of 25 healthy older men and women (average age of 70 years) had muscle tissue samples taken and compared to the gene profile from muscle samples taken from 26 younger healthy men and women (average age 21 years). Fourteen of the older adults completed six months of twice-weekly resistance training and the results were then compared to the younger adults. The older adults were relatively active (golfing, walking, gardening, tennis, cycling three or more times a week but were not competitive athletes) and healthy; the younger adults were relatively inactive or participated in modest recreational activities, and none were athletes. These inclusion criteria allowed the investigators to study the effect of aging with subjects selected to be matched for activity level and not merely the effect of inactivity. None of participants took medication or had diseases that
