Do Heavy Lifting Stimulate Fast Twitch Muscle Fibres?

i do think that you should continue training even when you've injured a leg, because studies have shown over and over again you do get contralateral benefits. In others, 20 19 journal of physiology, they took ten recreationally trained young men. They performed four resistance exercise conditions. The idea is that only a heavy lifting is going to stimulate those high threshold motor units, those fast twitch muscle fibres.
