Skeletal Muscle Adaptations

The application of blood flow restriction (BFR) during resistance exercise is increasingly recognized for its ability to improve rehabilitation and for its effectiveness in increasing muscle hypertrophy and strength among healthy populations. However, direct comparison of the skeletal muscle adaptations to low-load resistance exercise (LL-RE) and low-load BFR resistance exercise (LL-BFR) performed to task failure is lacking. Using a within-subject design, we examined whole muscle group and skeletal muscle adaptations to 6 wk of LL-RE and LL-BFR training to repetition failure. Muscle strength and size outcomes were similar for both types of training, despite ~33% lower total exercise volume (load × repetition) with LL-BFR than LL-RE (28,544 ± 1,771 vs. 18,949 ± 1,541 kg, P = 0.004). After training, only LL-BFR improved the average power output throughout the midportion of a voluntary muscle endurance task. Specifically, LL-BFR training sustained an 18% greater power output from baseline and resulted in a greater change from baseline than LL-RE (19 ± 3 vs. 3 ± 4 W, P = 0.008). This improvement occurred despite histological analysis revealing similar increases in capillary content of type I muscle fibers following LL-RE and LL-BFR training, which was primarily driven by increased capillary contacts (4.53 ± 0.23 before training vs. 5.33 ± 0.27 and 5.17 ± 0.25 after LL-RE and LL-BFR, respectively, both P < 0.05). Moreover, maximally supported mitochondrial respiratory capacity increased only in the LL-RE leg by 30% from baseline ( P = 0.006). Overall, low-load resistance training increased indexes of muscle oxidative capacity and strength, which were not further augmented with the application of BFR. However, performance on a muscle endurance test was improved following BFR training.

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.
