The Overload Principle is a fundamental concept in exercise physiology that states in order to improve physical fitness, the body must be subjected to stress beyond its current capabilities. This principle guides the progressive increase of exercise intensity, duration, or frequency to stimulate adaptation and enhance performance.

fundamental concept

Exercise physiology is the study of how the body's structures and functions are altered when exposed to acute and chronic bouts of physical activity. It examines the body's responses at the molecular, cellular, and systemic levels, aiming to optimize performance, improve health, and prevent or treat diseases.

Physical fitness is a state of health and well-being that allows individuals to perform daily activities with vigor, reduce the risk of chronic diseases, and improve mental health. It encompasses various components such as cardiovascular endurance, muscular strength, flexibility, and body composition, all of which can be improved through regular physical activity and a balanced diet.

Duration is a measure of the sensitivity of the price of a financial asset, typically a bond, to changes in interest rates, expressed in years. It provides investors with an estimate of the potential price volatility and helps in managing interest rate risk within a portfolio.

Frequency is a fundamental concept in physics and engineering that refers to the number of occurrences of a repeating event per unit of time. It is crucial in understanding wave phenomena, signal processing, and various applications across different scientific disciplines.
