Specificity of Types of Muscle Fibers
Type IIB and Type IIA Muscle Fiber Types and Specificity

11-B-Muscle-Fibers-Ed-MartelType IIB muscle fibers are fast twitch glycolytic and are the speed producers.  Type IIA muscle fibers are fast twitch oxidative and are intermediate speed producers.  Structured training has been proven to make our recruitment of muscle types more efficient.  The recruitment of muscle types depends on our nervous systems ability to recruit motor units.  The way to optimize motor unit recruitment with an overhead athlete is to provide a stable base for power.  The amount or percentage of high twitch glycolytic fibers in any athlete is a product of genetics.  We are born with the amount we have which is why everyone does not throw 100 mph.  An efficient movement pattern developed over time allows the athlete to conserve energy and throw harder with less effort.  Your maximum velocity depends on your mechanics and where in the throwing motion you apply speed.  This is exactly what our program will accomplish.  We will incorporate our knowledge of specificity of training to maximize your ability to accelerate the ball in the most efficient way available.  There are no shortcuts and perfect repetition is the only way to reach your goals.

You need to Correct athletes before you Create athletes.  This is the philosophy and foundation of The OAI program.
