cardiac power-to-weight ratio
Measurement of cardiac output normalized to body weight, used to assess cardiovascular fitness efficiency.
Full Definition
Cardiac power-to-weight ratio represents the relationship between cardiac power output and an athlete's body weight, providing insight into cardiovascular efficiency and fitness level. This metric is particularly valuable in sports cardiology for comparing cardiovascular performance across athletes of different sizes and in monitoring training adaptations. The ratio is calculated by dividing cardiac power output (measured in watts) by body weight in kilograms, allowing for normalized comparison of cardiac performance.
Usage
Usage note: Not to be confused with general power-to-weight ratio used in mechanical contexts or cardiac output index which uses body surface area.
