Acute resistance exercise with blood flow restriction effects on heart rate, double product, oxygen saturation and perceived exertion

Abstract

The aim of this study was to compare the acute effect of resistance exercise (RE) with and without blood flow restriction (BFR) on heart rate (HR), double product (DP), oxygen saturation (SpO2 ) and rating of perceived exertion (RPE). Twenty-four men (21·79 ± 3·21 years) performed three experimental protocols in a random order (crossover): (i) high-intensity RE at 80% of 1RM (HI), (ii) low-intensity RE at 20% of 1RM (LI) and (iii) low-intensity RE at 20% of 1RM combined with partial blood flow restriction (LI+BFR). HR, blood pressure, SpO2 and RPE were assessed. The data were analysed using repeated measures analysis of variance and the Wilcoxon test for RPE. The results indicated that all protocols significantly increased HR, both immediately postexercise and during the subsequent 60 min (P<0·05), and postexercise DP (P<0·05), but there were no differences between protocols. The protocols of LI and LI+BFR reduced postexercise SpO2 (P = 0·033, P = 0·007), and the LI+BFR protocol presented a perception of greater exertion in the lower limbs compared with HI (P = 0·022). We conclude that RE performed at low intensity combined with BFR seems to reduce the SpO2 after exercise and increase HR and DP while maintaining a perception of greater exertion on the lower limbs.

Hemodynamic responses to strength exercise with blood flow restriction during different phases of the menstrual cycle

“…The primary results of the present study were as follows: i) the three groups exhibited increased SBP, HR and DP but did not exhibit differences on SpO2; ii) the LL and LL+BFR treatments resulted in greater hemodynamic increases compared with the HI treatment; and iii) the phases of the MC seem to influence only HR and DP. Nonetheless, we observed a significant increase in SBP, HR and DP among the three exercise groups, and between the few studies that evaluated these variables after RE with BFR (Araújo et al, 2014;Brandner, Kidgell, & Warmington, 2015;Neto et al, 2016;Okuno et al, 2014), two corroborate with our findings (Brandner et al, 2015;Neto et al, 2016). These authors reported increased SBP, DBP and MBP (Brandner et al, 2015) and HR and DP (Brandner et al, 2015;Neto et al, 2016) immediately after LL with BFR and after LL and HI exercises.…”

These authors reported increased SBP, DBP and MBP (Brandner et al, 2015) and HR and DP (Brandner et al, 2015;Neto et al, 2016) immediately after LL with BFR and after LL and HI exercises. Thus, we concluded that the increased values observed in the present study are within the normal patterns, which reinforces the safety of both continuous and intermittent BFR (Brandner et al, 2015).…”

“…The BFR training method has been used to increase strength (Laurentino et al, 2012;Silva et al, 2015;Vechin et al, 2015), muscle mass (Laurentino et al, 2012;Vechin et al, 2015), muscular endurance (Gil et al, 2017;Kacin & Strazar, 2011), and functional capacity (Araujo et al, 2015) and was shown to be safe (Araújo et al, 2014;Neto et al, 2015;Neto et al, 2016;Takano et al, 2005). In this scenario, gains in strength and muscle mass with the use of this technique have been shown to be as effective as high-intensity resistance training (HI; ≥ 80% of 1RM).…”

“…Some studies evaluated the acute effects of resistance exercises with BFR on systolic blood pressure (SBP), diastolic blood pressure (DBP), mean blood pressure (MBP), heart rate (HR), double product (DP) (Araújo et al, 2014;Neto et al, 2015;Neto et al, 2016;Okuno, Pedro, Leicht, Ramos, & Nakamura, 2014;Rossow et al, 2012;Rossow et al, 2011;Takano et al, 2005;Vieira, Chiappa, Umpierre, Stein, & Ribeiro, 2013) and oxygen saturation (SpO2) (Neto et al, 2016). However, no studies have evaluated these variables after sessions of resistance exercitation with BFR performed during the MC phases (follicular, ovulatory and luteal).…”
