The purpose of this study was to compare the systolic blood pressure (SBP) and diastolic blood pressure (DBP) responses during two different strength training (ST) surfaces: stable (SST) and unstable (UST). Fifteen trained normotensive women performed 4 nonconsecutive 10RM load test sessions (test and retest for both surface methods) for a whole-body workout. After the load tests, subjects performed two training sessions (SST and UST) with 3 sets of each exercise with loads of 85% of 10RM with a 2-min rest between sets and exercises. The ANOVA two-way showed the same pattern of magnitude reduction on SBP after both training sessions (SST and UST). However, a prolonged reduction of SBP was evident from the SST method (~60 min). For DBP, there were no significant differences between workouts. Thus, although a ST session might trigger a general post-exercise hypotensive effect regardless of the surface method applied (SST and UST), it seems that this effect is more durable after sessions performed with the traditional SST.
