Heart attacks and lower-limb function in master endurance athletes
Key result
Top-level master endurance athletes had a significantly lower risk of myocardial infarction compared with healthy controls over 11 years (0.7% vs 5.3%; OR 0.15; 95% CI 0.03-0.67; P=0.0059).
Why the study?
Does long-term competitive endurance sports training reduce the risk of myocardial infarction and lower-limb disability in middle-aged men?

Main Result
Odds Ratio: 0.15 (95% CI 0.03–0.67)
Absolute Event Rate: 0.7% vs 5.3%
p-value: p=0.0059
Long-term competitive endurance training in middle-aged men is associated with a significantly reduced risk of myocardial infarction and lower-limb disability, despite a higher prevalence of knee osteoarthritis.

Kujala et al. (1999) conducted a cohort in Healthy adults (n=457). Competitive endurance sports vs. Healthy nonsmoking controls was evaluated on Myocardial infarctions (OR 0.15, 95% CI 0.03-0.67, p=0.0059). Top-level master endurance athletes had a significantly lower risk of myocardial infarction compared with healthy controls over 11 years (0.7% vs 5.3%; OR 0.15; 95% CI 0.03-0.67; P=0.0059).
