The Effect of Varying Eccentric Velocity on Muscle Hypertrophy

Resistance training is essential to muscle hypertrophy as it fatigues fibres through time-under-tension (TUT). As myocyte energy depletes, metabolites accrete, leading inflammation increase cell size, so adapted for future stimuli. TUT can be measured by varying eccentric velocities: i.e., the rate at which a lengthens under load. A longer period of lengthening will lead greater metabolite accretion and inflammation. However, unknown whether threshold or if gradually more growth. Through literature review experiment, this project investigates effect velocity on hypertrophy. Previous research in field physiology metabolism were explored, with an emphasis training. The supplementary experiment shoulder growth response medial deltoid exercise called lateral raises, where different velocities assigned groups. Individualistic daily calorie protein intake controlled ensure that sufficient nutrients available recovery performance. Surprisingly, post-experimental suggested high-velocity was best due levels force production. This consistent found group fast-velocity eccentric, lower TUT, experienced They also exhibited strength gain neuromuscular junction adaptation.
