Post-Exercise Hypotension between Different Protocols of Resistance Training for Beginners.

Evidence indicates that resistance training (RT) promotes post-exercise hypotension (PEH), which is considered important in preventing hypertension (HTN). But, the most efficient RT protocol to keep blood pressure normal is still unclear. The aim of this study was to analyze and compare the impact of different RT protocols on PEH. Twelve male and female subjects (22.0 ± 1 yrs of age with a mass body index of 24.9 ± 2 m²) participated in this study. The sample size was calculated using the GPower 3.0.10 software for a statistical power of 80% with an alpha of 5% (P≤0.05). The subjects performed in randomized order two experimental RT protocols: (a) the strength training (ST) protocol suggested for beginners (80% 1-RM); and (b) the muscular endurance (ME) protocol (65% 1-RM). Heart rate and blood pressure were measured before and every 15 min of recovery after the session (up to 60 min). While both protocols resulted in PEH, the ST protocol produced a longer PEH response than did the ME protocol. Therefore, the findings indicate that for beginners, the ST protocol is more effective in producing PEH. [ABSTRACT FROM AUTHOR]
