Load-dependent postrace SV reduction with preserved EF; hypothesis-generating for transient effects of prolonged exercise in recreational runners.
Does prolonged exercise alter left ventricular function and cTnT levels in recreational marathon runners?
Prolonged exercise in recreational marathon runners causes a load-dependent decrease in stroke volume and frequent cTnT elevation, but no load-independent depression in LV systolic function.
George et al. (2004) studied this question.
