Term
Define the overload principle and how does it work
Definition
Training concept that the demands placed on a system (cardiorespiratory or muscular) must be increased systematically and progressively over time to cause physiological adaptation (development or improvement)
It works if muscle cells are overloaded beyond their normal use, such as in strength-training programs, the cells increase in size (hypertrophy) and strength
