Endurance cyclists demonstrated a faster cardiac response during the transition from rest to exercise, characterized by faster cardiac output, left ventricular filling, and untwisting.
Observational
What are the kinetics of left ventricular function during the transition from rest to constant-load exercise in endurance-trained subjects?
Left ventricular twisting mechanics play a key role in the more efficient acute cardiac response of endurance-trained athletes at the onset of exercise.
Our study assessed for the first time, to our knowledge, the kinetics of left ventricular function during the transition from rest to constant-load exercise in endurance-trained subjects. We observed a faster cardiac response in cyclists characterized by a faster response of cardiac output, left ventricular transmitral filling, basal rotation, and untwisting. This study highlighted the key role of left ventricular twisting mechanics in the more efficient acute cardiac response of endurance-trained athletes at onset of exercise.
Izem et al. (Thu,) conducted a observational in Endurance-trained subjects. Constant-load exercise was evaluated on Kinetics of left ventricular function. Endurance cyclists demonstrated a faster cardiac response during the transition from rest to exercise, characterized by faster cardiac output, left ventricular filling, and untwisting.
