heartcapacity
Heart capacity refers to the maximum amount of blood the heart can pump out with each beat, also known as stroke volume, and the total amount of blood it can pump per minute, known as cardiac output. Stroke volume is influenced by factors such as the size of the heart's ventricles and the force of their contractions. Cardiac output is the product of stroke volume and heart rate, meaning it increases with both a stronger beat and a faster beat.
Athletes often exhibit increased heart capacity due to physiological adaptations from regular training. Their hearts can
Medical conditions can also affect heart capacity. Heart failure, for example, is characterized by a reduced
