What is muscular endurance?

Muscular endurance is the ability of muscles to produce relatively low levels of force for a prolonged period of time. Improving muscular endurance is extremely important for helping us to maintain good posture. The ability to maintain good posture during exercise is critical to preventing increased stress and reducing the potential for injury to our joints and connective tissues.

Muscular endurance is the ability of a muscle or group of muscles to sustain repeated contractions against a resistance for an extended period of time. Muscular endurance is very important for people playing sports and who have to sustain an activity for long periods of time. Muscular endurance is determined by how well your slow twitch muscle fibers are developed. There are generally two types of muscle fibers in your body, slow twitch and fast twitch. Slow twitch muscle fibers cannot exert as much force as fast twitch, but can sustain an effort over a much greater period of time. Fast twitch muscle fibers can exert a great amount of force but for a very limited amount of time. Therefore, slow twitch equals endurance, while fast twitch equals strength.
