Acute Blood Pressure Response to Different Resistance Programs in Trained Men

ABSTRACT

Abstract Background Resistance training is used in different exercise programs, with different objectives and different levels of physical fitness. Training-related variables, such as volume, rest time and intensity, can affect the response of blood pressure (BP), but studies on the effect of these variables on BP are still needed. Objective To evaluate the acute response of BP in trained individuals undergoing two different methods of resistance training. Methods The sample was divided into three groups (1) the German volume training (GVT) (n= 15), which consisted of 10 series of 10 repetitions at 50% of 1-repetition maximum (RM) with intervals of 30 seconds; (2) the sarcoplasm stimulating training (SST) (n= 16), performed at 8 RM and 85% of 1-RM and interval of 10 seconds until failure, followed by removal of 20% of weight and repetition of the whole series (total of three sets), and the control group (CG) (n= 15) who underwent BP measurements only. The two-way repeated measures ANOVA was used for analysis of variations, and a p< 0.05 was considered statistically significant. Results In the within-group analysis, a significant lowering of systolic blood pressure (SBP) was found at 10 minutes (125.4±10.8 mmHg, p= 0.045) and 20 minutes (124.5±8.5 mmHg, p= 0.044) post-training compared with immediately after training. In the between-group comparison, higher SBP values were observed immediately after training in the SST group (142.1±28.2, p= 0.048) compared with the CG. Conclusion High-volume and high-intensity resistance training programs did not cause abnormal changes in blood pressure. (Int J Cardiovasc Sci. 2021; [online].ahead print, PP.0-0)
