Application of force to an object in excess of the force it was intended or designed to withstand. It has the potential for causing permanent deformation or damage to the structure or its support.
A greater than normal stress or demand placed on a physiological system or organ, typically resulting in an increase in strength or function.
Method used to increase the workload beyond the body’s normal capacity or to improve and develop muscular strength and endurance.
A training principle in which those being trained are required to work at a level beyond normal demands.
Placing a greater-than-normal amount of stress (within reason) on the body in an attempt to make it function at a higher capacity.
Key training concept that states that the demands placed on the cardiovascular or muscular system must be systematically and progressively increased over a period of time to cause physiologic adaptation (that is, development or improvement).
