Summary To compare the hypotensive effect and performance responses between different resistance training intensities and different exercise orders in apparently healthy women, thirteen apparently healthy women performed four resistance training sessions in randomized order. One group performed the resistance training exercises with 60% of 1RM (SeqA60%): leg press (LG), chest press (CP), leg extension (LE), lat pull down (PD), leg curl (LC) and biceps curl (BC). Another group performed the resistance training exercises with 80% of 1RM (SeqA80%) with the same exercise order. Two other groups performed the resistance training exercises with 60% (SeqB60%) and 80% of 1RM (SeqB80%), however, in another sequence of exercises: CP, PD, BC or LG, LE, LC. The blood pressure was measured before, and at every 15 min until 60 min postexercise. The different intensities and different exercise orders resulted in a significant hypotensive effect in systolic and diastolic blood pressures that remained until 15 min. In addition, significant reductions in systolic blood pressure were observed at 30 min for SeqA in both intensities and for SeqB with intensities of 80% of 1RM. However, there was no significant difference between intensities and different prescription orders (P>0·05). Although the current study showed significant decreases in systolic and diastolic blood pressures after different resistance training sessions, the manipulation of intensity and exercise sequence, such as those used in the present study, was not able to generate significant changes in the duration and magnitude of hypotensive effect.
