Muscular Endurance

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. In case your wondering what slow twitch muscle fibers are, I will explain. 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. It is important to pay attention to muscular endurance if you play any sort of sports, or are involved in any sort of physical activity thats lasts for quite a while. For example, such sports as hockey, football, tennis, etc. Another acitivity that is very dependant on muscular endurance is cross country running, in fact it is probably the best example of muscular endurance, as it involves very little muscular strength or flexibilty. If you are looking to improve muscular endurance, the best way would be to involve yourself in just about any cardivascular activity, such as running, biking, and playing sports. Even walking will help you stay healthy and condition your leg muscles, to a point. If you are looking to improve the endurance of your upper body, bodyweight exercises such as chin-ups, push-ups, triceps dips, etc., will improve this, and your strength as well. Different sports require different levels of muscular endurance. While each program will vary according to the athlete's needs, muscular endurance can be split into 3 groups:

Power Endurance
Athletes like baseball pitchers, sprinters, 50-m freestyle swimmers, martial artists, wrestlers, fencers, tennis players and so on must produce powerful movements and repeat them several times with little or no rest. In
