Vascular and Inflammatory Acute Responses after a Resistance Exercise Session in Young Women with Excessive Adiposity
BACKGROUND: Endothelial dysfunction and low-grade inflammation are both positively associated to states of excessive adiposity but reports on the acute effects of resistance exercise on these variables are still lacking. We evaluated these acute effects of resistance exercise on vascular reactivity and on the inflammatory profile in young women. METHODS: Participants were divided into two groups: lean Controls (n=16) and Overweight (n=16). The resistance exercise session consisted of unilateral elbow flexions for five sets of 10 repetitions at 70% of one repetition maximum. Blood pressure, heart rate, forearm blood flow, vascular conductance, cytokines, adipopeptides and endothelin-1 were evaluated at rest and during the acute post-exercise period. RESULTS: The overweight group had higher forearm blood flow at rest (p=0.03) and during post-exercise (p<0.001) while forearm vascular conductance was higher only during post-exercise, at 20 (p=0.02) and 40 min (p<0.001). Endothelial-dependent vasodilation was higher during the post-exercise period in the Overweight group compared to controls (p=0.01). In the Overweight group, the resistance exercise session reduced interleukin-6 (p=0.02) and leptin (p<0.001) but increased endothelin-1 levels (p=0.02). CONCLUSIONS: We conclude that the single resistance exercise session elicited an acute increment of baseline vascular reactivity and an increased endothelial-dependent vasodilation with concomitant changes in inflammatory profile and endothelin-1 in our tested women with excessive adiposity.
