Key result
Endurance distance running in prepubertal boys was associated with greater maximal stroke and cardiac indices during progressive exercise compared to untrained controls.
Why the study?
Does progressive upright cycle exercise elicit different cardiac responses in trained male prepubertal distance runners compared to untrained control boys?
Population
22 male prepubertal boys, comprising trained distance runners (n=8) and untrained controls (n=14)
Comparison
Progressive upright cycle exercise to exhaustion vs Untrained control boys undergoing the same…

Does progressive upright cycle exercise elicit different cardiac responses in trained male prepubertal distance runners compared to untrained control boys?
Trained prepubertal distance runners exhibit a progressive increase in stroke volume during exercise, differing from untrained boys and showing quantitative differences compared to adult athletes.
Rowland et al. (1998) reported a cross-sectional. Endurance distance running vs. Untrained controls was evaluated on Cardiac variables (stroke index, cardiac index, stroke volume) during progressive upright cycle exercise. Endurance distance running in prepubertal boys was associated with greater maximal stroke and cardiac indices during progressive exercise compared to untrained controls.
