Abstract
The purpose of our study was to determine if vascular occlusion produced an additive
effect on muscle hypertrophy and strength performance with high strength training
loads. Sixteen physically active men were divided into two groups: high-intensity
(HI = 6 RM) and moderate-intensity training (MI = 12 RM). An occlusion cuff was attached
to the proximal end of the right thigh, so that blood flow was reduced during the
exercise. The left leg served as a control, thus was trained without vascular occlusion.
Knee extension 1 RM and quadriceps cross-sectional area (MRI) were evaluated pre-
and post-8 weeks of training. We only found a main time effect for both strength gains
and quadriceps hypertrophy (p < 0.001). Therefore, we conclude 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
Key words
hypertrophy - cross‐sectional area - leg extension
