5. cardiorespiratory fitness(English)

   • reflects the ability of the muscles to perform dynamic work, relying on the respiratory and CV system for transport of oxygen (O2) to and carbon dioxide (CO2) from the working muscles. A small ventricle is strongly associated with low fitness because of the combined effect of a smaller resting stroke volume and an attenuated capacity to increase with exercise
