Key result
In a 45-year observational study of 54 male marathon runners, extreme high-intensity and sustained exercise was associated with low CVD incidence and extended longevity versus the general population.
Why the study?
Does prolonged high-intensity marathon running increase cardiovascular disease mortality or reduce longevity in male runners compared to the general population?
Population
54 male long-distance marathon runners from a Southern California men's running club
Comparison

Does prolonged high-intensity marathon running increase cardiovascular disease mortality or reduce longevity in male runners compared to the general population?
Long-term, high-intensity marathon running was associated with low cardiovascular disease incidence and extended longevity in a small cohort of male runners, challenging the notion that extreme exercise is cardiotoxic.
Benjamin L. Rosin (2017) conducted an observational in Cardiovascular disease (n=54). Marathon running (high and sustained intensity exercise) vs. General population was evaluated on Incidence of death from cardiovascular disease and age at death. In a 45-year observational study of 54 male marathon runners, extreme high-intensity and sustained exercise was associated with low CVD incidence and extended longevity versus the general population.
