Dose Effects

Our previous study reported that metabolic stress in skeletal muscle achieved by combining moderate blood flow restriction (BFR) with low-intensity resistance exercise at 20% of one repetition maximum (1 RM) could not reach the level achieved by high-intensity resistance exercise. Since the previous protocol is typical of current regimens of this type, we sought in this study to optimize the exercise protocol for low-intensity resistance exercise with BFR by examining the dose effects of exercise intensity and pressure. Twelve healthy subjects participated in this study. They were asked to perform unilateral plantar flexion for 2 min (30 repetitions/min) under six different conditions: two resistance exercises (20% 1 RM and 65% 1 RM) without BFR, and four BFR protocols. The four BFR protocols included three different exercise intensities (20, 30, and 40% 1 RM) with moderate pressure (MP) using 130% of systolic blood pressure (147 ± 17 mmHg, mean ± SD) and 20% 1 RM with high pressure at 200 mmHg. Intramuscular metabolites and pH were obtained by 31P-magnetic resonance spectroscopy. Significant dose effects on intramuscular metabolites and pH were observed for exercise intensity ( P < 0.001) but not for BFR pressure. The BFR protocol combining 30% 1 RM with MP had similar results as the high-intensity load at 65% 1 RM. Intramuscular metabolic stress during BFR exercise might be susceptible to increasing exercise intensity. To replace high-intensity resistance exercise, the BFR protocol might require an intensity of ≥30% 1 RM.

AbstractIntroduction: The blood flow restriction method is a training method that is based on the partial occlusion of circulation during a workout. This technique combines low-intensity exercise with the occlusion of the bloodstream which produces results similar to high-intensity training.Aim: We aimed to identify the areas in which this method is applicable, its potential benefits and effects, recommendations regarding the rules of use for maximal effects (dosage, intensity, etc.), and also possible contraindications or warnings regarding the use of this method.Methods: We have analyzed a number of 20 articles on this topic from the field literature of the last 10 years, using ”google academic” as a search engine.Results: After this study we concluded that blood flow restriction is a method with wide applicability in the field of sports training, but also in the recovery process; however, it requires attention in choosing the necessary equipment. For healthy individuals, best training adaptations occur when combining low-load blood flow restriction resistance exercise with traditional high-load resistance exercise.Conclusion: Low-intensity resistance exercise with blood flow restriction is as effective as high-intensity training (for strength and muscle mass gains), but only the high-intensity protocol promotes significant hypotensive responses after exercise.

Introduction: Low-intensity resistance exercises with blood flow restriction are known to be effective in promoting muscular strength and hypertrophy; however, there is a paucity of evidence on their acute hemodynamic responses. Objective: To compare the changes in muscular oxyhemoglobin (O2Hb), deoxyhemoglobin (HHb) concentrations, and O2 saturation (StO2) during low load exercise under free blood flow (FreeBF) and blood flow restriction (BFR). Methods: Fifteen healthy males were subjected to bilateral knee extension tests under FreeBF and BFR conditions, in a random order. The knee extension exercise included four sets of 15 repetitions at 20% of one-repetition maximum, with 30s interval between the sets. In the BFR condition, subjects exercised with a cuff positioned on the proximal thigh and inflated to 50% of total occlusion pressure. Changes in the O2Hb, HHb, total hemoglobin (tHb), and StO2 in vastus lateralis muscle were monitored using near-infrared spectroscopy. Results: A two-way repeated-measures ANOVA revealed significant main effects for sets for all variables (P < 0.05). Moreover, the values in StO2 during sets 2, 3, and 4 in BFR conditions were significantly lower than those in freeBF. Significant differences were also seen between the exercise conditions during rest intervals for HHb (rest intervals 2, 3, and 4) and tHb (rest interval 3; P < 0.05). There were no significant interactions between conditions and sets or conditions and intervals for O2Hb. Conclusion: Low-intensity resistance exercise performed with BFR significantly decreased the acute muscle StO2 and increased total muscle hemoglobin.
