Key result
Participation in a long-distance ski race was associated with a lower risk of death, myocardial infarction, or stroke compared with non-skiers (HR 0.56; 95% CI 0.54-0.58).

Ski race participation was associated with lower CVD incidence; supports lifestyle hypothesis but leaves causality open in observational data.

Participation in a long-distance ski race, indicative of a highly active lifestyle, is associated with a significantly lower risk of cardiovascular disease and all-cause mortality compared to the general population.
Hållmarker et al. (2018) conducted a cohort in cardiovascular diseases (n=399,630). Participation in a long-distance ski race vs. Non-skiers was evaluated on death, myocardial infarction, or stroke (HR 0.56, 95% CI 0.54-0.58). Participation in a long-distance ski race was associated with a lower risk of death, myocardial infarction, or stroke compared with non-skiers (HR 0.56; 95% CI 0.54-0.58).
