The exercise is called drug-free exercise. Polypill Many doctors believe that exercise can benefit nearly everyone because it can prevent and treat many chronic diseases associated with aging at low cost. In addition, exercise-induced changes reprogram the epigenetic expression of fibers to a more youthful state. Therefore, the answer to the question “can exercise slow down muscle aging?” is “yes, it can,” according to research.
There’s mounting evidence that people of all ages who exercise regularly not only build stronger muscles, but also improve their overall health. It’s never too late to make healthy lifestyle changes.
Recent studies have shown that exercise Risk of deathand Cardiovascular diseaseas well Alzheimer’s and Parkinson’s Disease In older adults, reduced muscle strength and mass are associated with frailty, reduced quality of life, and Increased all-cause mortality.
“Exercise is the most powerful medicine we have,” says Kevin Muhlach, PhD, assistant professor at the Exercise Science Research Center at the University of Arkansas in Fayetteville, Arkansas.
Rewinding the clock in muscle fibers
Exercise may reverse the clock on aging muscle fibres by promoting epigenetic reprogramming of cell nuclei. Previous studies have shown that transcription factors can affect the expression of specific genes when they bind to specific DNA sequences.
Nobel Prize The medicine prize-winning research found that four transcription factors can revert specialized mature cells back into more youthful, flexible cells called pluripotent stem cells. These four factors are called Oct3/4, Klf4, Sox2, and Myc, and are referred to as OKSM for short.
Recent Research
Research published in Journal of Physiology Comparing the effects of OKSM factors on gene expression in muscle fibers from mice with and without exercise wheels, the effects of OKAM factors on muscle were also compared with the effects of single transcription factors. The researchers found that exercise induced the expression of Myc more strongly than other factors.
The researchers also looked at how exercise alone affected gene expression in muscle fibers in humans and old mice. Mice in the exercise group ran freely on an unweighted wheel for one week, then had weights added to the wheel over an eight-week period, gradually increasing the weight.
According to the researchers, the results suggest that exercise reprograms muscle fibres to a more youthful state by increasing the expression of Yamanaka factors, particularly the gene that makes Myc.
What does this mean?
The researchers believe that their work may one day help develop drugs to enhance muscle responses to exercise in bedridden people or astronauts in zero gravity, but they dismiss the idea of a drug that boosts Myc expression or replaces exercise.
Exercise has positive effects on the whole body, not just muscles, and because Myc is associated with cancer, artificially boosting its expression may carry inherent risks. Additionally, a pill could have unintended consequences, such as blocking some of the beneficial effects of exercise.
“There is evidence that ‘lifespan-extending’ drugs such as metformin and rapamycin block the positive effects of exercise, particularly in skeletal muscle,” Murak said, explaining that it is possible that the drugs block the epigenetic reprogramming of muscle that occurs with exercise.
Exercises for seniors
Older adults looking to start exercising for preventative reasons may benefit from low-impact, total-body exercise that focuses on the lower body and core.
Swimming has many benefits for seniors that are often overlooked. Swimming is low-impact and gentle on joints, increases flexibility in the neck, arms, hips and legs, and improves balance, coordination, posture and balance. Swimming is a total-body exercise that gets your heart rate up and keeps your cardiovascular system strong. Swimming helps increase bone density and improves stability, reducing the risk of falls. Swimming also helps relax the mind and body, relieve stress and improve the quality of your sleep.
Strength and Resistance Training It’s suitable for almost everyone and is recommended in the American Heart Association’s Physical Activity Guidelines for Adults.
Walking is perhaps the easiest form of exercise to do, and when combined with stretching, resistance and mobility training, most adults can walk anywhere, anytime, every day, which can improve their overall health and well-being.
