MRI Evaluation of Right Ventricular Adaptation to Resistance Versus Endurance Training: a 6-month Randomised Trial

To determine whether 6-months of controlled, supervised, intensive endurance (E) or resistance (R) training induces RV adaptation. Twenty-three young male subjects were randomized into either E (n=10) or R training groups (n=13) and completed a 6-month intensive, progressive training intervention, a...

Description
Summary:To determine whether 6-months of controlled, supervised, intensive endurance (E) or resistance (R) training induces RV adaptation. Twenty-three young male subjects were randomized into either E (n=10) or R training groups (n=13) and completed a 6-month intensive, progressive training intervention, attending 3x1 hr fully supervised sessions per week. Variables included MRI-assessed cardiac morphology, body composition, aerobic fitness and muscular strength. Aerobic fitness significantly improved in E (3.55+ or -0.22 to 3.79+ or -0.18 L.min-1, P=0.024) but was unchanged in R. Muscular strength significantly improved in both groups, but to a greater extent in R (27.3+ or -4.6 vs. 37.5+ or -4.9%, P
