Saffold KS, Hornikel B, MacDonald HV, Aguiar EJ, Wind SA, Winchester LJ. Acute Decrements in Performance and Recovery of the Distal Musculature with Automated Blood Flow Occlusion in the Proximal Limb. JEPonline 2023;26(1):40-52. Most blood flow restriction (BFR) devices use a set pressure to occlude flow, and the effects of these devices on post-exercise recovery in the distal musculature have not been thoroughly explored. This study evaluates the effect of BFR on fatigue during resistance exercise in the musculature distal to the occlusion site. Twenty participants (age: 23 [+ or -] 4 years) completed two exercise sessions with or without BFR in a crossover-design. The participants performed 3 sets of 15 repetitions of maximum ankle plantarflexion (PF) and dorsiflexion (DF) on an isokinetic dynamometer. Eighty percent limb occlusion pressure (LOP) was applied to the thigh during BFR. Isokinetic dynamometer metrics were evaluated during the exercise. Gastrocnemius cross sectional area (CSA) was measured pre-exercise and post-exercise. A toe-tap test, average step length test, and counter-movement jump test were employed to evaluate fatigue and recovery from pre-exercise to post-exercise. Repeated measures ANOVA was used to determine significant differences. BFR caused a significant reduction in peak torque (P = 0.009), average force (P KEY WORDS: Blood Flow Occlusion, BFR Performance, Distal Occlusion, Fatigue, Post-Exercise Recovery
INTRODUCTION Blood flow restriction (BFR) is well known for its ability to induce metabolic stress, resulting in adaptations in muscular strength and hypertrophy at loads well below the recommended 65% [...]
