Resistance training with 2-minute and 3-minute rest intervals resulted in a greater reduction in post-exercise blood pressure compared to 1-minute intervals (p<0.05).
RCT (n=18)
randomized counterbalanced order
Do longer rest intervals (2 or 3 minutes) during resistance training improve post-exercise blood pressure and heart rate variability compared to 1-minute rest intervals in physically active men?
Using 2-minute or 3-minute rest intervals during resistance training provides a better stimulus for acute post-exercise blood pressure reduction than 1-minute intervals in physically active men.
p-value: p=<0.05
The purpose of this study was to compare blood pressure and heart rate variability responses in physically active men after performing resistance training sessions with rest intervals of 1 min, 2 min and 3 min. Eighteen men (age, 21.6±1.1 years; body mass, 74.1±8.1 kg; body height, 175.3±7.1 cm) who performed 180min of physical activity per week participated in this study. After determining the 15RM loads for the squat, bench press, bent-over row and deadlift, participants performed a resistance training session. Participants performed three resistance training protocols in randomized counterbalanced order. Each experimental protocol comprised different rest intervals between sets of resistance training exercises (1min, 2min or 3min). During each experimental session, participants performed three sets with a 15RM load. Blood pressure and heart rate variability were measured before and for 2h after each session. The results demonstrated a greater blood pressure (p<0.05) reduction with a longer rest interval. There was no statistically significant difference in heart rate variability changes between groups. These results indicate that 2min and 3min rest intervals while using a 15RM load provide the best stimulus for a blood pressure reduction response after a resistance training session. Our findings suggest that strength and conditioning professionals should prescribe 2min or 3min rest intervals when resistance training is performed with a 15RM load if the aim is to obtain an acute reduction in blood pressure after a resistance training session.
Alemi et al. (Tue,) conducted a rct in Physically active men (n=18). Resistance training with 2 min or 3 min rest intervals vs. Resistance training with 1 min rest interval was evaluated on Blood pressure and heart rate variability (p=<0.05). Resistance training with 2-minute and 3-minute rest intervals resulted in a greater reduction in post-exercise blood pressure compared to 1-minute intervals (p<0.05).
