Mood Effects of Blood Flow Restriction Resistance Exercise Among Basketball Players

This study compared the acute effects of resistance exercise with and without blood flow restriction (BFR) on basketball players’ mood states. A total of 11 male basketball players (M age = 19.9, SD = 2.8 years; M height = 180.8, SD = 7.8 cm; M weight = 71.1, SD = 9.1 kg; M body mass index = 22.1, SD = 1.9 kg/m2) were randomly assigned to two experimental conditions: (a) low-load resistance exercise with BFR (LLRE + BFR) and high-load resistance exercise (HLRE) without BFR. We measured mood state with the Brunel Mood Scale before and after each session. There was a significant interaction effect such that there was increased fatigue over time with LLRE + BFR ( p = .001, Δ% = 169.2). Regarding total mood disorder, there were significant pre and postexercise differences between athletes exposed to both the LLRE + BFR and HLRE conditions ( p = .048) and a decharacterization of the iceberg mood profile in the post-training LLRE + BFR condition. LLRE + BFR, compared to HLRE, promoted an acute negative effect on mood state, decharacterization of the iceberg profile, total mood disturbance, and increased participant fatigue, suggesting that this method of strength training should be avoided before sports competitions.

Transient Improvement

Distortion to hemodynamic and ischemic stimuli during blood flow restriction (BFR) exercise may influence regional vascular adaptation. We examined changes at the conduit, resistance, and capillary level in response to low load resistance exercise with BFR. Eleven males (22 ± 3 yr, 178 ± 4 cm, 78 ± 9 kg) completed 6 wk (3 days/wk) unilateral plantar flexion training with BFR at 30% 1 repetition maximum (1-RM). The contralateral leg acted as a nonexercised control (CON). Popliteal artery function [flow-mediated dilation, FMD%] and structure [maximal diameter] and resistance vessel structure [peak reactive hyperemia] were assessed using Doppler ultrasound before and at 2-wk intervals. Calf filtration capacity was assessed using venous occlusion plethysmography before and after training. BFR training elicited an early increase in peak reactive hyperemia (1,400 ± 278 vs. 1,716 ± 362 ml/min at 0 vs. 2 wk; t-test: P = 0.047), a transient improvement in popliteal FMD% (5.0 ± 2.1, 7.6 ± 2.9, 6.6 ± 2.1, 5.7 ± 1.6% at 0, 2, 4 and 6 wk, respectively; ANOVA: P = 0.002), and an increase in maximum diameter (6.06 ± 0.44 vs. 6.26 ± 0.39 mm at 0 vs. 6 wk; Bonferroni t-test: P = 0.048). Capillary filtration increased after 6 wk BFR training ( P = 0.043). No changes in the CON leg were observed. Adaptation occurred at all levels of the vascular tree in response to low load resistance exercise with BFR. Enhanced peak reactive hyperemia and transient improvement in popliteal artery function occurred before changes in artery structural capacity.

Flow Restriction

BACKGROUND During aging, a significant loss of muscle mass, strength, and power is associated with a decline in daily functional capacities. Traditionally, resistance training is prescribed to prevent or reverse the skeletal muscle weakness, but the required training intensity may be too demanding for older people with poor physical performance. Resistance exercise with blood flow moderation (KAATSU training), originally developed in Japan, combines resistance exercise with blood flow restriction. It has been reported that KAATSU training enhances muscle hypertrophy in many populations. However, few studies have evaluated the effects of resistance exercises with blood flow restriction in elderly people and how this affects vascular structure and function. OBJECTIVE The aim of this study was to evaluate (1) the acute and chronic effects of resistance exercise with blood flow restriction on vascular health in elderly people with low gait speed and (2) whether low-load resistance training with blood flow restriction elicits similar strength and gait speed gains to those elicited by conventional resistance training without blood flow restriction. METHODS This is an ongoing randomized controlled trial in elderly people with low gait speed. Overall, two study arms of 13 participants each perform resistance exercise with and without blood flow restriction. The 2 groups are as follows: the control group will perform conventional resistance exercise (60% of 1 repetition maximum) and the KAATSU group will perform the low-load resistance exercise with blood flow restriction (20% of 1 repetition maximum) for 12 weeks. Pulse wave velocity, venous occlusion plethysmography, and flow-mediated dilation are used to assess arterial stiffness, muscle blood flow, and endothelial function, respectively. The secondary outcomes are gait speed, strength, and quality of life. All measures will be performed before and after the training program. RESULTS This research study is in progress. Recruitment has started, and data collection is expected to finish in August 2020. CONCLUSIONS The findings of this study will have important implications for the rehabilitation of elderly people.

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.
