Cardiovascular surgeon Dr. Jeremy London has identified two key metrics that significantly impact heart health and longevity: VO2 max and muscle mass. In a video shared with over a million followers on social media, London explained how these factors contribute to extended health span and lifespan. VO2 max, a measure of the body’s ability to utilize oxygen during intense exercise, is highlighted as the top indicator of longevity. London, who is based in Savannah, Georgia, noted that scientists have observed substantial improvements in cardiovascular health and increased lifespan among individuals with higher VO2 max levels.
London added that muscle mass is another critical element, as it plays a vital role in maintaining independence and the ability to perform daily activities as one ages. He emphasized that building muscle mass doesn’t always require intense weightlifting or strenuous exercise, and recommended a variety of activities such as dancing, swimming, walking, or yoga. The key, he said, is consistency and finding a balance between what one needs and what they enjoy for physical activity. By maintaining these two metrics, individuals can significantly enhance their overall health and longevity.
London’s insights are supported by recent research from Harvard Medical School, which confirmed the correlation between higher VO2 max levels and better physical fitness, as well as a lower risk of cardiovascular disease. The research underscores the importance of regular physical activity in keeping VO2 max levels high throughout one’s life. He also pointed out that even those who have not exercised in a long time can still benefit from incorporating simple, accessible forms of physical activity into their routines. The focus is on making exercise a sustainable and enjoyable part of daily life, which in turn supports long-term health and longevity.
