Speed 101 Training Improves Aerobic and Anaerobic Performance Research has shown that there are two types of muscle fibers known as slow and fast twitch. Slow twitch muscle fibers are smaller and are powered by aerobic metabolism chemistry. Fast twitch muscle fibers are larger and powered by anaerobic metabolism chemistry. Generally, a muscle with a higher percentage of fast twitch fibers reacts more quickly but fatigues sooner. Slow twitch fibers provide longer lasting power but are relatively slow to react. The Speed 101 program strives to achieve a balance between slow and fast twitch muscle development through a series of core physical exercises and the use of specialized speed and strength training equipment. For All Sports and Athletes Speed 101 is applicable to all sports and athletes, male and female. Whether for soccer or football, tennis or baseball; Speed 101 is designed to improve speed and agility, strength and stamina - factors critical to all sports. Exercises, Drills, Specialized Equipment and Fun! A variety of exercises, drills and specialized equipment are used to improve general conditioning and muscle toning, aerobic capacity and anaerobic efficiency leading to significant improvements in strength, agility and speed. SPARQ Certified Rating (New!) The SPARQ Rating is a number that identifies overall athletic ability and is used by top coaches and trainers around the nation as an indicator of an athletes potential on the field. . |
