Muscle Fiber Activation
Andy explains the principle of all or none, which means that when a muscle fiber contracts, it contracts with 100% effort. The only way to regulate force production is to increase or decrease the total amount of motor units that are activated. This principle is used in post activation potentiation, where you activate higher threshold motor units to jump with more force and velocity.In this clip
