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.

OBJECTIVE: Verify the influence of different exercise orders on the performance of the number of maximal repetitions in older women.
METHODS: Twelve older women (65.7 ± 5.6 years, 66.9 ± 9.5 kg, 1.56 ± 0.67 m, 27.4 ± 3.6 kg/m2) underwent four nonconsecutive visits and two different orders of Resistance Training. At the first visit, the volunteers were submitted to anamnesis, anthropometric evaluation and a 10RM test. On the second visit, a re-test of 10RM was performed. On the third and fourth visits, the volunteers performed two exercise sequences: sequence A: bench press, latissimus pulldown close grip, biceps curl, triceps extension; for sequence B the order was inverted. Performance was measured by the number of repetitions in each exercise. To determine differences in performance for sequence A vs. sequence B, repeated measures were performed by two-way ANOVA followed by the Tuckey post-hoc test.
RESULTS: The number of repetitions of each exercise varied significantly for the bench press, biceps curl and triceps extension between the exercise sequences.
CONCLUSIONS: The order of the exercises performed in a resistance training session can affect the performance in the number of repetitions in older women.
