Why the study?
Does ultra-endurance exercise cause transient myocardial injury and right ventricular dysfunction in athletes?
Population
27 athletes (20 male, 7 female) participating in an ultra-endurance triathlon
Comparison
Ultra-endurance triathlon vs Baseline measurements (1 week before the race)
Design
Cohort
Follow-up
1 week post-race

Transient post-race changes warrant no practice change; leaves open cumulative cardiac effects of repeated ultra-endurance events.
Does ultra-endurance exercise cause transient myocardial injury and right ventricular dysfunction in athletes?
Intense ultra-endurance exercise causes transient myocardial damage and a significant reduction in right ventricular function, which almost entirely resolves within one week.
Gerche et al. (2007) studied this question.
