Single muscle fiber adaptations with marathon training. Therefore, having a higher percentage of slow-twitch fibers would suit endurance activities such as running or cycling. Read our Peloton Tread review to learn about our experience. As for the MCAT (which this video was targeted for), some topics are more superficial. We make a lot more energy By adopting slower reps, you can stimulate muscles for longer, which could contribute toward muscle growth. Your slow-twitch muscle fibers are working hard whenever youre doing an activity or exercise that needs muscles to work or even stay still for a long time. Type I fibers produce less force and are slower to produce maximal tension (lower myosin ATPase activity) compared to type II fibers. But some muscles have more slow-twitch fibers because they have to do the same job for a long time. Fast twitch muscles are optimal for short, quick bursts of energy. DOI: Daniel Bubnis, M.S., NASM-CPT, NASE Level II-CSS. Skeletal muscles contain both types of fibers, but the ratios can differ depending on a variety of factors including muscle function, age and training. present in greater quantities.
