BEIJING: Chinese researchers have unveiled compelling evidence that moderate exercise longevity benefits hold the key to healthy ageing. A study by Sun Yat-sen University analysed data from 20,924 participants aged 50 and above, revealing crucial insights into physical activity, sedentary behaviour, and their impacts on lifespan and ageing.
The findings, derived from the Guangzhou Biobank Cohort Study, show that moderate physical activity significantly enhances longevity. Compared to low activity levels, engaging in moderate exercise increases the likelihood of living longer by an impressive 56%. The study highlights that the frequency, duration, and intensity of moderate activity directly contribute to better outcomes.
Interestingly, vigorous physical activity does not offer similar benefits. In fact, extended periods of vigorous exercise may inversely affect longevity and even accelerate ageing.
The researchers also explored how exercise influences ageing. Regular moderate physical activity was found to reduce the risk of accelerated ageing by over five years. Conversely, prolonged vigorous exercise was linked to a higher risk of accelerated ageing over the same period.
Another critical finding is the role of lipids. The study suggests that moderate exercise exerts protective effects on longevity and slows ageing, partly through its impact on lipid profiles. However, sedentary behaviour remains a significant risk factor, contributing negatively to accelerated ageing.
This research reinforces the long-standing advice to “sit less and move more” as a cornerstone of healthy living. By promoting moderate exercise, individuals can enjoy extended lifespans and mitigate the risks of premature ageing.
The study underscores the importance of incorporating sustainable, moderate-intensity activities like walking or cycling into daily routines to optimise health and longevity.
