Cardiovascular Health Implications
Practical take-away: for the vast majority of the population, increased cardio is of paramount importance. Veteran ultra endurance athletes should consider possible negative health outcomes until more definitive information is presented.
“An exercise-induced increase in soluble Suppression of Tumorigenicity (sST2) was observed in all marathon runners with sST2 concentrations exceeding cut-off values both at baseline (48%) and finish (94%). Faster runners had higher sST2 concentrations.” This biomarker shows that marathon running potentially puts excess strain on the heart.
