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 issue 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 could alter mitochondrial function.
The resistance training was done on standard gym equipment. The twice- weekly sessions ran an hour in length and involved 30 contractions of each muscle group Involved. Strength was tested based on knee extension, and tissue samples were taken from thigh muscles (“Exercise reverses aging,” 2012). Results In the rent study snowed Tanat multinational satisfaction was ten most common a ?catheter?o to emerge from the gene expression profile. Exercise resulted in a reversal of the genetic profile back to levels similar to those seen in the younger adults.
Furthermore, the resistance training increased the older group?was muscle strength. Before exercise training, the older adults were 59% weaker than the younger adults; but after training, the strength of the older adults improved by about 50%, such that they were only 38% weaker than the young adults. This study gives people one more reason to get physically active. Not only will it help attain or maintain a healthy weight and reduce the risk of disability due to arthritis, this study now shows that it may actually reverse the biologic aging that takes place in muscle cells (“Exercise reverses aging,” 2012).
Being physically fit after age 60 helps you live longer, regardless of your body’s fat content. In my opinion, I think fitness is an important part to know when studying human aging because of all the benefits it has on aging. Knowing what can help the elderly feel better about themselves is very important. Keeping them motivated and active will keep them feeling better and at a rower risk of disease and immobility. If a person is planning on going too field working with older adults it is important to keep some type of physical activity available for them.
I think if more older adults knew about the awesome benefits staying active has, they would be more willing to exercise and stay mobile. If I get into a field working with older adults for example a nursing home I think I would incorporate my findings into providing a better physical activity program to meet the requirements of each individual. There are many physical and emotional problems that can occur during aging. The more active you are the more chance you have of keeping on top of these problems and not having them affect you in your later years in life.
Many of the physical and emotional problems of aging include depression, hip and Joint problems, arthritis, heart problems, breathing problems, and lack of mobility or flexibility. During the aging process starting some type of fitness program should first require a visit to your doctor so that you can make sure that whatever activity you are planning to add to your lifestyle is doctor approved. You want to be sure that your physical condition is going to allow you to safely incorporate fitness onto your lifestyle and the aging of your body.
