“The only and most important message from this study is that even a little exercise seems to be very helpful.”
Copenhagen Denmark- The secret to staying young may be to keep your muscles moving throughout your life. Researchers at the University of Copenhagen have found that physically active older people have more fatigue-resistant muscles and more stem cells that regenerate function.
According to the team, this is the first study to examine the activity of human muscles, stem cells, and nerves. They surveyed 46 elderly men with an average age of 73 years. These men fall into one of three categories: young sedentary men (15), older lifelong exercise (16), and older sedentary men (15).
Elderly participants who were regularly active in resistance exercises, ball games, racket sports, swimming, cycling, running, or boating had higher numbers of muscle stem cells in their bodies. Also called satellite cells, it plays a major role in muscle regeneration and muscle growth and prevents nerve deterioration.
Old but active is young and defeats inactive
During the study, each participant used a mechanical chair to perform a resistance exercise to extend the knee. The authors of the study measured the force produced by each person before taking blood samples and muscle biopsies from both feet. The results revealed that older lifelong exercisers outnumbered both groups of sedentary men.
“This is the first study in humans to discover that lifelong exercise at the recreational level can delay some of the harmful effects of aging. Using a muscle tissue biopsy, it is common. We have discovered the positive effects of exercise on the aging population. This is missing from the literature, as previous studies focused primarily on the minority group Master Athletes, “said lead author Caspersonden. Blow states in a media release.
“Our study is more representative of the general population over the age of 60 because the average person is more likely to participate in a mix of activities at a moderate level. Therefore, recreational activities are carried out. I wanted to investigate the relationship between the content of satellite cells in an individual and muscle health. It could be used as a biomarker to further investigate the relationship between exercise, aging, and muscle health. increase.”
“The only most important message from this study is that even a small amount of exercise seems to be of great help when it comes to protecting against age-related declines in muscle function. This is what more people say. It’s an encouraging discovery if you can drive yourself into an activity you’re enjoying. You’ll still learn a lot about the mechanisms and interactions between nerves and muscles, and how they change with age. We need to. Our research brings us one step closer, “the researchers conclude.
The authors of the study state that it is still necessary to investigate the effects of lifelong exercise on people over the age of 80. Future studies will also need to look at the relationship between women’s recreational activities and muscle health.
