“…In this study BLa 2 was not different between the conditions. Unchanged BLa 2 between conditions is likely the result of RSE being completed at maximal intensity, and this observation is supported by recent research investigating leg or arm-cycling RSE with BFR that is volume equated (16,19) or completed to exhaustion (37)(38)(39). Similar BLa 2 was observed in all conditions despite lower mean power output during C-BFR and I-BFR REST than during Non-BFR.…”

Mckee, JR, Girard, O, Peiffer, JJ, and Scott, BR. Manipulating internal and external loads during repeated cycling sprints: A comparison of continuous and intermittent blood flow restriction. J Strength Cond Res XX(X): 000–000, 2023—This study examined the impact of blood flow restriction (BFR) application method (continuous vs. intermittent) during repeated-sprint exercise (RSE) on performance, physiological, and perceptual responses. Twelve adult male semi-professional Australian football players completed 4 RSE sessions (3 × [5 × 5-second maximal sprints:25-second passive recovery], 3-minute rest between the sets) with BFR applied continuously (C-BFR; excluding interset rest periods), intermittently during only sprints (I-BFRWORK), or intraset rest periods (I-BFRREST) or not at all (Non-BFR). An alpha level of p < 0.05 was used to determine significance. Mean power output was greater for Non-BFR ( p < 0.001, d z = 1.58 ), I-BFRWORK ( p = 0.002, d z = 0.63 ), and I-BFRREST ( p = 0.003, d z = 0.69 ) than for C-BFR and for Non-BFR ( p = 0.043, d z = 0.55 ) compared with I-BFRREST. Blood lactate concentration ( p = 0.166) did not differ between the conditions. Mean oxygen consumption was higher during Non-BFR ( p < 0.001, d z = 1.29 and 2.31; respectively) and I-BFRWORK (p < 0.001, d z = 0.74 and 1.63; respectively) than during I-BFRREST and C-BFR and for I-BFRREST ( p = 0.002, d z = 0.57) compared with C-BFR. Ratings of perceived exertion were greater for I-BFRREST ( p = 0.042, d z = 0.51) and C-BFR ( p = 0.011, d z = 0.90) than for Non-BFR and during C-BFR ( p = 0.023, d z = 0.54) compared with I-BFRWORK. Applying C-BFR or I-BFRREST reduced mechanical output and cardiorespiratory demands of RSE and were perceived as more difficult. Practitioners should be aware that BFR application method influences internal and external demands during RSE.

“…A study by Manimmanakorn et al (2013) demonstrated that low-loading resistant exercise combined with BFRT significantly improved 0–5m and 0–10 m sprint abilities in female netball players. Possible explanations for the improvement in sprint performance are related to positive muscle responses, leading to increasing lower-limb power output ( Doma et al, 2020 ; Ienaga et al, 2022 ). Metabolic accumulation (e.g., lactic acid) caused by restricting blood flow led to cell swell and promotes the secretion of growth hormone, resulting in increases in the muscle cross-sectional area and motor unit recruitment ( Takarada et al, 2000 ).…”

Purpose: The aim of this study was to explore the acute effects of Blood Flow Restriction Training (BFRT), Whole-Body Vibration (WBV), and BFRT + WBV on the 20 m sprint, muscle activation, and metabolic accumulation in male sprinters.Method: Sixteen male sprinters randomly performed BFRT, WBV, or BFRT + WBV interventions with 72 h intervals. Electromyography (EMG) signals were collected before and during interventions. Fingertip blood was taken before, immediately after, and 15 min after the intervention. 20 m sprint was performed before and 3 min after the intervention.Results: 1) 0–10m and 0–20 m sprint performance were significantly improved after WBV and BFRT + WBV interventions (p < 0.05), 0–20 m sprint performance was significantly improved after all three interventions (p < 0.05), 2) After BFRT + WBV intervention, the EMG amplitude of the vastus lateralis and soleus were significantly improved. Greater increases in EMG activity of the tibialis anterior muscle (p < 0.05)and blood lactate (p < 0.05)were observed following BFRT intervention compared to BFRT + WBV intervention.Conclusion: For sprint performance, BFRT and WBV had similar post-activation enhancement effects to BFRT + WBV, and the metabolic accumulation immediately following the BFRT were higher than that following BFRT + WBV in male sprinters.

“…These authors found significant increases in the expression of HIF-1α only in the L-IEH group. Ienaga et al 15 investigated the effects of L-IEH during an SIT training consisting of three sets of 6 s maximum sprints with 24 s rest between sprints and 5 min rest between sets. They found higher deoxyhaemoglobin and lower tissue saturation index (StO 2 ) in L-IEH.…”

High-intensity interval training (HIIT) is a popular method for optimising sports performance and, more recently, improving health-related parameters. The inclusion of hypoxia during HIIT can promote additional gains compared with normoxia. However, reductions in the effort intensities compared with the same training performed in normoxia have been reported. Studies have reported that adding hypoxia during periods of inter-effort recovery (IEH) enables maintenance of the intensity of efforts. It also promotes additional gains from exposure to hypoxia. Our call is for researchers to consider IEH in experiments involving different models of HIIT. Additionally, we consider the need to answer the following questions: What is the clinically relevant minimum dose of exposure to hypoxia during the recovery periods between efforts so that favourable adaptations of parameters are associated with health and sports performance? How does the intensity of exertion influence the responses to hypoxia exposure during recovery periods? What are the chronic effects of different models of HIIT and hypoxia recovery on sports performance?
