Resumen:
Low-moderate intensity aerobic exercise (e.g., brisk walking for 30–60 min/day) has well-documented beneficial cardiovascular effects, whereas those of strenuous endurance exercise (SEE) e.g., marathon running, are more controversial. Notably, the increasing popularity of SEE has contributed to the growth of sports-related sudden cardiac death (SCD) over the last decade. In this regard, Pineda et al. have underlined the importance of appropriate precompetition screening in order to minimize the risk of SCD during sport events.
