AB BackgroundResistance training is hardly recommended for postmenopausal women to counteract negativeeffects of hormonal changes. However, some concern exists about the marked hemodynamicresponses caused by high-load resistance exercises. In this regard, studies onyoung, healthy, physically active individuals suggest that set configuration can modulateacute cardiovascular, metabolic, and cardiac autonomic responses caused by resistancetraining sessions, but this has not yet been explored in postmenopausal women.MethodsA sample of 60 physically active postmenopausal women (30 normotensive, 30 hypertensive)will participate in this crossover study. After a medical exam, ergometry, familiarizationsession, and two testing sessions, participants will complete three experimental sessionsand one control session in a randomized order. Each experimental session includes 36 repetitionsof four exercises (horizontal leg press, bench press, prone leg curl, and lat pulldown)differing in set configuration: 9 sets of 4 repetitions (i.e., 33% intensity of effort) with45 s of inter-set recovery, 6 sets of 6 repetitions (50% intensity of effort) with 72 s, and 4 setsof 9 repetitions (75% intensity of effort) with 120 s; with 4 min rest between exercises. Beforeand immediately after each session, arterial stiffness, hemodynamic variables, cardiac autonomicmodulation, baroreflex sensitivity, sympathetic vasomotor tone, and resting oxygenuptake will be evaluated. Furthermore, perceived effort, mechanical performance (e.g.,power, velocity), heart rate, and lactatemia will be collected throughout sessions. Theimpact of set configuration on these variables will be analyzed, along with comparisonsbetween normotensive and hypertensive women. DiscussionCardiovascular responses to resistance exercise have been scarcely studied in females,particularly postmenopausal women. The results of this study will provide information aboutthe modulating role of set structure on metabolic and cardiovascular responses of normotensiveand hypertensive postmenopausal women to resistance training.
