Why Exercise is the Ultimate Shield Against Muscle Ageing

Regular exercise may play a crucial role in maintaining muscle strength and slowing age-related decline, according to cardiovascular surgeon and scientist Dr Subodh Verma. The University of Toronto professor has highlighted the importance of physical activity in preserving mobility, improving overall health and supporting independence as people grow older. His comments come amid increasing scientific interest in how exercise affects muscle health and the ageing process.

Age-related loss of muscle mass and strength, known as sarcopenia, is a natural part of ageing. However, experts say the pace of muscle decline can vary significantly depending on lifestyle factors, including physical activity levels. Maintaining an active routine that includes strength training, aerobic exercise and regular movement can help older adults preserve muscle function and reduce the risk of mobility-related challenges.

In an Instagram video shared on July 8, Dr Verma discussed recent research examining the relationship between exercise and muscle ageing. The heart surgeon explained that physical activity does more than simply improve fitness levels; it can influence the health and performance of muscles by helping maintain strength and resilience over time. He highlighted exercise as an important tool for supporting healthier ageing.

Muscles play a vital role beyond movement. They contribute to balance, metabolism, energy regulation and overall physical independence. As people age, reduced muscle strength can increase the risk of falls, injuries and difficulty performing daily activities. According to health experts, consistent exercise can help counter these changes by stimulating muscle maintenance and improving functional capacity.

Dr Verma's explanation comes as researchers continue studying the concept of biological ageing and whether lifestyle habits can influence how quickly tissues deteriorate. Emerging evidence suggests that physically active individuals often show healthier muscle characteristics compared with those who lead sedentary lifestyles. However, experts note that exercise does not completely prevent ageing but may help the body remain stronger and more resilient.

A balanced fitness routine is generally considered most effective for maintaining muscle health. Resistance exercises such as weight training or bodyweight movements help strengthen muscles, while activities like walking, cycling and swimming support cardiovascular fitness. Flexibility and balance exercises can also improve mobility and reduce injury risks, particularly among older adults.

Dr Verma, known for his work in cardiovascular medicine and research, has frequently discussed the connection between lifestyle choices and long-term health outcomes. His message emphasises that exercise should be viewed not only as a way to improve physical appearance or athletic ability but also as a foundation for maintaining health throughout life.

While individual exercise needs vary based on age, health conditions and fitness levels, experts recommend adopting regular physical activity as part of a healthy lifestyle. Along with a balanced diet, adequate sleep and preventive healthcare, exercise remains one of the most effective strategies for supporting healthy ageing and preserving quality of life.
