Vascular
Occlusion at low intensity has been shown to produce increases in muscle
hypertrophy but what about high intensity exercise. At high forces, muscle contraction per se may restrict blood
flow to a similar extent as external vascular occlusion, thus negating any
additional effects of cuff occlusion to high strength training loads. Researchers assigned subjects to 4 groups: A.
high intensity-no occlusion, B) High Intensity with occlusion, C.) Moderate
Intensity- no occlusion, D.) Moderate Intensity-Occlusion. Both the HI and the MI groups performed
unilateral knee extension exercise training. The HI group trained with a load
of 6 RM and the MI group with a load of 12 RM, corresponding to ~ 80%
and 60% 1RM,
respectively. At the end of the study,
In the present study, they not find an additive training effect on muscle
hypertrophy and strength gains when vascular occlusion was combined with
training intensities that mimic a real
world setting. Strength
gains and quadriceps hypertrophy increased without
any correlation to vascular
occlusion. Therefore, they concluded that vascular occlusion in combination
with high-intensity strength training does not augment muscle strength or
hypertrophy when compared to high-intensity strength training
alone.
