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

Related Questions
I have a question about the episode 250 ‒ Training principles for longevity | Andy Galpin, Ph.D. (PART II) and the clip Muscle Fiber Activation. When talking about strength, Andy Galpin said it's all about total force. Is it more about training your nervous system through intensity, with fewer repetitions but as much frequency as you want? Am I correct in understanding that you are training the nervous system to recruit more fibers efficiently to produce higher total force? How did I do in understanding this concept?
