“…Therefore, it may be suggested that there may be an interaction between resistive load, cuff width and cuff pressure, which determines the magnitude of acute changes in performance during exercise under BFR, which is also consistent with previous studies (Loenneke et al, 2012b;Rossow et al, 2012). A possible explanation for the increases in PV of the bar for both I-BFR and C-BFR, may be ischemic preconditioning (de Souza et al, 2019). Ischemic preconditioning is a noninvasive technique inducing transient peripheral hypoxia and subsequently enhancing tissue tolerance against ischemiareperfusion (Paradis-Deschênes et al, 2016).…”

“…However, the effects of previous ischemia would be expected to be enhanced in each subsequent set, which was not the case in the present study, as improvements in PV were observed in only the first four loads. An additional factor which may influence peak performance in both I-BFR and C-BFR may be related with the bidirectional brain-body integration mechanism, which may promote physiological responses through mechanical-sensory receptors (Taylor et al, 2010;Cromwell and Panksepp, 2011;de Souza et al, 2019) thus increasing resistance exercise performance (de Souza et al, 2019). Such physiological responses may potentially explain the significant increase in PV for conditions under BFR compared to NO-BFR.…”

This study evaluated the effects of continuous and intermittent blood flow restriction (BFR) with 70% of full arterial occlusion pressure on bar velocity during the bench press exercise against a wide range of resistive loads. Eleven strength-trained males (age: 23.5 ± 1.4 years; resistance training experience: 2.8 ± 0.8 years, maximal bench press strength – 1RM = 101.8 ± 13.9 kg; body mass = 79.8 ± 10.4 kg), performed three different testing protocols in random and counterbalanced order: without BFR (NO-BFR); intermittent BFR (I-BFR) and continuous BFR (C-BFR). During each experimental session, subjects performed eight sets of two repetitions each, with increasing loads from 20 to 90% 1RM (10% steps), and 3 min rest between each set. In the C-BFR condition occlusion was kept throughout the trial, while in the I-BFR, occlusion was released during each 3 min rest interval. Peak bar velocity (PV) during the bench press exercise was higher by 12–17% in both I-BFR and C-BFR compared with NO-BFR only at the loads of 20, 30, 40, and 50% 1RM (p < 0.001), while performance at higher loads remained unchanged. Mean bar velocity (MV) was unaffected by occlusion (p = 0.342). These results indicate that BFR during bench press exercise increases PV and this may be used as an enhanced stimulus during explosive resistance training. At higher workloads, bench press performance was not negatively affected by BFR, indicating that the benefits of exercise under occlusion can be obtained while explosive performance is not impaired.

“…Specifically, recovery of power production and sprint performance were improved. Compared with other IR studies [ 25 , 26 ], the authors used a short protocol (two bouts of 3 min of ischemia followed by 3 min of reperfusion; 2 cycles × 3 min). Based on this protocol, Northey et al [ 27 ] evaluated the velocity of recovery applying the PEIC immediately after a fatiguing resistance exercise protocol.…”

It has been demonstrated that brief cycles of ischemia followed by reperfusion (IR) applied before exercise can improve performance and, IR intervention, applied immediately after exercise (post-exercise ischemic conditioning—PEIC) exerts a potential ergogenic effect to accelerate recovery. Thus, the purpose of this systematic review with meta-analysis was to identify the effects of PEIC on exercise performance, recovery and the responses of associated physiological parameters, such as creatine kinase, perceived recovery and muscle soreness, over 24 h after its application. From 3281 studies, six involving 106 subjects fulfilled the inclusion criteria. Compared to sham (cuff administration with low pressure) and control interventions (no cuff administration), PEIC led to faster performance recovery (p = 0.004; ES = −0.49) and lower increase in creatine kinase (p < 0.001; effect size (ES) = −0.74) and muscle soreness (p < 0.001; ES = −0.88) over 24 h. The effectiveness of this intervention is more pronounced in subjects with low/moderate fitness level and at least a total time of 10 min of ischemia (e.g., two cycles of 5 min) is necessary to promote positive effects.
