The Truth About Exercise and Longevity: Is More Always Better?

 

 

1. Exercise and Moratality : What the Research Says

A recent study from the University of Jyväskylä in Finland challenges the widely accepted belief that more exercise leads to a longer life. The research, published in the European Journal of Epidemiology, analyzed data from over 22,750 twins born before 1958. The study tracked their physical activity levels through surveys conducted in 1975, 1981, and 1990, and followed their mortality rates until the end of 2020.

 

The findings indicate that those who exercised at a moderate level had the lowest mortality rates. Surprisingly, individuals who exercised the most did not live significantly longer than those who were less active. In fact, the group that exercised the least had a mortality rate up to 7% lower than the most active group.

 

 

 

2. The Relationship Between Exercise and Biological Aging

Researchers also analyzed biological aging using blood samples and found a U-shaped correlation between exercise and aging. Those who exercised too little or too much showed faster biological aging. The most active individuals had a biological age 1.3 years older than those who exercised in moderation. This suggests that excessive exercise may accelerate aging rather than slow it down.

 

 

3. Does WHO’s Exercise Recommendation Reduce Mortality?

 

The World Health Organization (WHO) recommends 150-300 minutes of moderate exercise or 75-150 minutes of vigorous exercise per week. However, the study found that following these guidelines did not significantly lower mortality rates or reduce the genetic risk of cardiovascular disease. Even twins who maintained the recommended level of exercise for 15 years showed no significant difference in mortality compared to their less active siblings.

 

 

 

4. Exercise and Cardiovascular Disease: The Role of Genetics

While exercise is known to improve metabolic and cardiovascular health, the study suggests that genetic factors play a significant role in cardiovascular diseases. The research estimates that genetic predisposition accounts for 40-60% of the risk for conditions such as hypertension, heart disease, and stroke. Experts emphasize that while exercise and a healthy lifestyle contribute to overall well-being, they cannot completely eliminate genetic risks. Individuals with a family history of cardiovascular disease should undergo regular check-ups and follow personalized treatment plans.

 

 

5. Conclusion

This study challenges the notion that exercising more guarantees a longer life. While moderate exercise has clear health benefits, excessive exercise may not necessarily contribute to longevity. The findings highlight the importance of a balanced approach to physical activity, emphasizing that moderation is key. Although exercise may not directly reduce genetic risks or extend lifespan, it remains crucial for improving overall health and metabolic function.
