Abstract
PURPOSE: We used a within-subject cross-over design to examine the impact of exercise modality, i.e. resistance (RT) and endurance (END), on the acute impact of exercise on endothelial function. Secondly, we examined whether 4-week exercise training altered the exercise-induced change in endothelial function in healthy individuals. METHODS: Forty young healthy men (21±2 years) reported to our laboratory to complete assessment of endothelial function (using the brachial artery flow-mediated dilation test [FMD]) before and immediately after a single bout of RT (leg-extension) or END (cycling). Subsequently, participants completed a 4-week period of training (12 sessions), followed by evaluation of the FMD before and after a single bout of exercise. Following a 3-week washout, participants repeated these experiments with the different exercise modality (in a balanced cross-over design). RESULTS: An Exercise*Modality-interaction effect was found (P=0.003), with post-hoc analysis revealing a decrease in FMD after END (P=0.03 and P<0.001, pre and post training respectively), but no change in FMD after RT (P=0.06 and P=0.39, before and after the training intervention respectively). Four weeks of exercise training did not alter the acute effect of exercise on FMD (Acute*Training*Modality effect: P=0.63), an effect independent of the modality of exercise (Acute*Training interaction: P=0.46 and P=0.11 in RT and END respectively). CONCLUSION: We found that exercise modality, but not exercise training, alters the effect of acute exercise on endothelial function in healthy subjects. Specifically, endurance exercise, but not resistance exercise, causes a decrease in brachial artery endothelial function, which was unaffected by 4 weeks of training.
