WebbEndurance athletes or long-distance runners have 90 to 95 percent slow- twitch muscle fibers. According to American Council on Exercise, slow-twitch fibers. are slighter and less powerful but more resilient to fatigue than fast-twitch fibers. So, they rely on oxygen to function properly. WebbThe amount stored depends on the animal species as well as on muscle fiber composition. It is well documented that triglycerides in the fast-twitch red muscle and to a lesser extent in the slow-twitch muscle, but not those in the fast-twitch white muscle, are mobilized during prolonged exercise.
