Research from University of Copenhagen reveals critical window for exercise in aging individuals
You’ve likely encountered the saying that it’s never too late to start exercising. While this holds some truth, recent research from the University of Copenhagen suggests that there is indeed a critical window that begins to close as we age, according to one of the study’s researchers.
Casper Søndenbroe, a Ph.D. in muscle physiology and aging, notes that specific nerve cells in the spinal cord can be preserved through physical activity. Should these neurons deteriorate, a significant decline in muscle strength may occur as we grow older. The findings indicate that if individuals wait too long to begin training, they might not be able to prevent the loss of these essential nerve cells.
Motor neurons play a vital role in controlling movement and signaling muscles to generate force. There comes a point, Søndenbroe warns, when it may be too late to salvage optimal aging.
He suggests that ideally, individuals should begin exercising before the age of 50, as the deterioration of nerve cells likely begins around age 60. To counteract this loss, he recommends engaging in activities like running or strength training two to three times a week.
He emphasizes the importance of strength in performing daily tasks as we age, as many may struggle with rising from a chair or navigating stairs without falling.
However, Søndenbroe reassures those who haven’t yet started exercising, affirming that any physical activity will be beneficial. He suggests prioritizing strength training, particularly for older adults, to enhance muscle strength.
Ultimately, he encourages individuals to begin incorporating exercise into their lives earlier rather than postponing it.
