Decreasing workloads in strength training makes it more tolerable for a broad range of people. When designed as blood-flow restriction training, similar gains in strength and muscle mass are achieved compared to traditional training. Adding high training loads to blood-flow restriction training only in the eccentric phase (BFR-ECC) might achieve superior gains in muscle strength while still maximizing tolerability of the training stimuli.
This study aims to investigate the acute physiological and perceptual response of blood-flow restriction training with eccentric loading in comparison to traditional eccentric training. The study recruits healthy individuals ≥ 18 years.
