WebApr 29, 2024 · The percentage of oxidative fibres was higher and that of glycolytic fibres was lower in Mashen pigs than in Large White pigs, which was consistent with the slow growth rate, low feed utilization rate, and low lean meat rate of Mashen pigs. This indicated that the muscle of Mashen pigs exhibits a high ability to use fat as a source of energy. WebPower athletes have a higher ratio of fast-twitch fibers (e.g., sprinters 70-75% type II), whereas for endurance athletes have more slow-twitch fibers (e.g., marathon/distance runners 70-80% type I) (2).
