Researchers at the University of Copenhagen found that strength training strengthens the connections between nerves and muscles, thereby protecting motor neurons in the spinal cord. The work was published in the American Journal of Physiology: Cell Physiology.

People start losing muscle mass rapidly around the age of 40. Part of the contraction of muscle fibers is due to the destruction of motor neurons in the spinal cord. While this process cannot be stopped, the authors have shown that it can be significantly slowed down.

The study involved 38 healthy elderly men. They completed a 16-week course of intense weight training. Participants performed leg presses, leg extensions, and forearm exercises. Another 20 healthy older men did not exercise and served as a control group. The average age of the participants was 72 years.

The workouts were performed three times a week. Midway through and at the end of the study, participants performed a muscle biopsy and found an increase in the content of biomarkers showing the connection between muscles and the nervous system. Researchers have shown that it’s never too late to start exercising, even if you’re 65 or 70.

Although this study was conducted in men, the results are likely to be true for women as well.
