JYVÄSKYLÄ, Finland – While exercise is widely recognized as a cornerstone of a healthy lifestyle, a new study from Finland suggests that more isn’t always better.researchers found that excessive physical activity may not provide additional health benefits and, in some instances, could accelerate biological aging.
The research, conducted by the University of Jyväskylä, examined the correlation between long-term physical activity, mortality risk, biological aging, and genetic predispositions. The findings challenge the notion that maximizing exercise intensity and duration invariably leads to improved health outcomes.
Optimal activity Level: Moderation is Key
The study analyzed data from 22,750 Finnish twins born before 1958. Participants’ physical activity levels were recorded in 1975, 1981, and 1990, and their mortality data was tracked until 2020.
Based on their activity levels over the 15-year period, participants were categorized into four groups:
- Sedentary (inactive)
- Moderately active
- Active
- Very active
The results indicated that the moderately active group had the lowest risk of death, approximately 7% lower than the sedentary group. However, increasing activity to high or very high levels did not yield further reductions in mortality risk.
“Pre-existing conditions can limit physical activity and ultimately cause death, not as of lack of sports itself,” said Associate Professor Elina Sillanpää from the Faculty of Sports and Health.She added that this could affect the short-term results in seeing the relationship between activity and death.
WHO Guidelines: Not a Guaranteed Mortality Shield
the study also assessed whether adherence to World Health Association (WHO) physical activity guidelines correlated with reduced mortality or genetic disease risk.The WHO recommends a minimum of:
- 150-300 minutes of moderate-intensity activity per week, or
- 75-150 minutes of vigorous-intensity activity per week
The study found that meeting these guidelines did not significantly decrease the risk of death or genetic diseases. Moreover, among identical twin pairs, no significant difference in mortality rates was observed between active and inactive twins.
“The relationship between physical activity and death that we have believed to originate from observational studies that are vulnerable to bias,” said Laura Joensuu, post -courtoral researcher involved in this study. “When we eliminate various sources of bias and see in the long run, we did not find evidence that complying with physical activity guidelines directly reduced genetic risk or mortality rates.”
Biological Aging: A U-Shaped Curve
Researchers also investigated the relationship between physical activity and biological aging, using epigenetic clocks to estimate participants’ biological age based on genetic markers in blood samples.
The findings revealed a U-shaped pattern: both the least active and the most active individuals exhibited accelerated biological aging.
“The fastest biological aging actually occurs in those who are the least and most exercise,” explained Sillanpää. This underscores the importance of balance in maintaining long-term health.
The study also noted that other lifestyle factors,such as smoking and alcohol consumption,exert a substantial influence on aging and health outcomes,possibly exceeding the impact of physical activity alone.
genetic Factors and Institutional Collaboration
The research incorporated genetic analysis of 4,897 twins, including 180 identical twin pairs, along with blood pressure assessments and heart disease risk evaluations based on polygenic risk scores. Biological aging levels were assessed in blood samples from 1,153 twins.
The Genactive Research Group, led by Elina Sillanpää, conducted the study in collaboration with the Faculty of Sports and Health Sciences and the Finnish Molecular Institute at Helsinki University.
Balance Over Extremes
The study suggests that moderate physical activity is sufficient to maximize health benefits and longevity. researchers emphasize the importance of a balanced lifestyle, encompassing various factors beyond exercise duration or intensity.
Sillanpää stated,”Exercise is still important,but don’t forget that other factors such as eating patterns,healthy living habits,and genetics also play a big role.”
The findings encourage individuals to reconsider their approach to exercise, focusing on balance and moderation rather than solely pursuing high-intensity or prolonged activity.
Moderate Exercise for longevity: What the Finnish Study Reveals
Q: What are the main takeaways from the Finnish study on exercise and longevity?
A: The key finding of the study, conducted by researchers at the University of Jyväskylä, is that more exercise isn’t always better. The study suggests that moderate physical activity is optimal for maximizing health benefits and potentially increasing longevity.Actually, excessive exercise may not provide additional benefits and, in some instances, could even accelerate biological aging. Balance and moderation appear to be key.

Q: What specific exercise categories were analyzed in the study, and how did mortality risk differ between them?
A: The study tracked the activity levels of over 22,000 Finnish twins. Participants were categorized into four groups based on their activity levels, recorded in 1975, 1981, and 1990:
- Sedentary (inactive)
- Moderately active
- Active
- Very active
The results showed that the moderately active group had the lowest risk of death. Increasing activity to high or very high levels in the study did not result yield further reductions in mortality risk.

Q: Did the study support the World Health Organization (WHO) guidelines for physical activity?
A: Interestingly, the study found that simply meeting WHO physical activity guidelines did not significantly decrease the risk of death or genetic diseases. The WHO recommends a minimum of:
- 150-300 minutes of moderate-intensity activity per week, or
- 75-150 minutes of vigorous-intensity activity per week
Furthermore, comparing identical twins, there were no notable differences in mortality rates between active and inactive twins.

Q: How did the study measure biological aging and what were the concerning findings?
A: Researchers used epigenetic clocks, which are based on genetic markers in blood samples, to estimate the biological age of the participants. The most striking finding was a U-shaped pattern. Surprisingly, both the least active *and* the most active individuals exhibited accelerated biological aging. This suggests that both insufficient and excessive exercise may negatively impact longevity.

Q: what other lifestyle factors were found to impact health outcomes?
A: The study also highlighted the significant impact of other lifestyle factors, such as smoking and alcohol consumption, on aging and health outcomes.These factors appeared to have a substantial influence, perhaps even exceeding the impact of physical activity alone. This reinforces the concept of holistic health.

Q: could pre-existing conditions have influenced the study’s outcomes?
A: associate Professor Elina Sillanpää pointed out that pre-existing conditions can limit physical activity and could also cause death. This could, in turn affect the short-term results when trying to analyze the relationship between activity and death alone.

Q: What is the significance of this study’s findings?
A: The study emphasizes the importance of a balanced lifestyle. It suggests that moderate physical activity might potentially be enough to maximize health benefits and longevity, rather than pushing for extreme levels of exercise.

Q: What do the researchers recommend in light of these findings?
A: The researchers encourage a balanced approach to health that goes beyond just exercise. Professor Sillanpää stated, “Exercise is still significant, but don’t forget that other factors such as eating patterns, healthy living habits, and genetics also play a big role.” The focus should be on a holistic approach that incorporates exercise,a healthy diet,and other wellness practices.
