Acute Hemodynamic Responses in Resistance Exercise: Effect of Number of Sets. JEPonline 2014;17(2):53-59. This study analyzed the effect of resistance exercise sets on resting and exercise heart rate (HR), systolic blood pressure (SBP), and double product (RPP) in 10 trained women. The 6 months of resistance training consisted of 4 series of 10 repetition maximum (RM) using a horizontal leg-press exercise with 2 min of rest between bouts. A one way ANOVA and the post hoc Tuckey test (P≤0.05) were used to find statistical significance. The findings indicate that SBP, HR, and RPP responses were significantly increased from rest to exercise. Systolic blood pressure was significantly increased between the 3rd and 4th sets vs. the 1st set. The number of sets increased SBP, but only when more than 2 sets were performed. The time of execution of each set and the rest interval between the sets was not high enough to induce a significant increase in HR and RPP.
