WebbSlow-twitch fibers use oxygen more efficiently and tend to contract more slowly. By contrast, fast-twitch muscle fibers fatigue faster, but they contract more powerfully and quickly. Your body determines which type of muscle to use depending on the amount of force you need to exert. For instance, fast-twitch fibers are put to use when you swim ... Webb3 jan. 2024 · For example: A kayaker on the Danish national team who was struggling in sprint events used the results of his muscle testing (which showed that his upper body had 90% slow-twitch muscle) to switch to endurance races. This switch allowed him to become one of the most competitive kayakers in the world. Webbthat splits ATP. Fast-twitch fibers have a more rapid ATPase (splitting of ATP into ADP + Pi) ability. Fast-twitch fibers also pump Ca2+ ions back into the sarcoplasmic reticulum very quickly, so these cells have much faster twitches than the slower variety. Thus, fast-twitch fibers can complete multiple contractions much more rapidly than slow ... phoebe east
