A new study has been released showing the importance of continued exercise as we age.
It is commonly believed that with aging comes an inevitable decline from vitality to frailty. This includes feeling weak and often the loss of independence. These declines may have more to do with lifestyle choices, including sedentary living and poor nutrition, than the absolute potential of musculoskeletal aging
We found that chronic intense exercise preserved muscle mass and prevented fat infiltration of muscle in masters athletes. Although changes in body composition were observed, including increased total BF, there was no decline in absolute muscle mass and the fat infiltration of muscle itself, IMAT, was not increased. These findings are in contrast with studies conducted in well-functioning men and women aged 70 to 79 years who are not considered masters athletes. In a study by Delmonico et al,19 both aging men and women were reported to have experienced an age-related increase in fatty infiltration of mid-thigh skeletal muscle.
Other studies suggest that is never too late to start – just twelve weeks of resistance exercises can have a noticeable improvement in quality of life for seniors.
Exercise can help you feel mentally better – sitting for long periods is linked to poor mental health (via Conditioning Research) . Regular exercise – without overtraining – has been shown to reduce the incidence of cold and flu.
As well as proving that exercise does improve health, we’re starting to learn more of the reasons of why. Researchers have discovered the hormone irisin which rises with exercise and stimulates the development of brown fat and reduces glucose sensitivity .
