The Original of Size Principle and Its Influence on Strength Training

Size principle is very important basically theory for strength training.This paper tries to review the background and the original references related to the size principle,the main purpose is to deepen understand the theory of size principle and to inspire the strength training practice.Applying HistCite software,we analyzed the development and influence of the size principle in sport science field.This paper finally put forward that in strength training,it is necessary to follow the principle of heavy load,the principle of exhaustive training load,in order to recruit more muscle fibers to participate in sports,better develop strength ability.At the same time,traditional strength and core strength training are discussed under the guidance of recruitment theory.It suggests that core strength training is a kind of coordination and stability training,it is one of the beneficial supplements of traditional resistance strength training.Stimulating the growth of the muscle fibers and recruitment must be done by resistance force.Traditional resistance training plays a fundamental role to improve the strength power.
