Cardio is a health-related part of physical fitness that is achieved by physical exercise.

Many physical attributes, such as heart rate, stroke volume, cardiac output, and maximal oxygen consumption, impact a person’s delivery of oxygen to working mucles.

Understand the connection between cardiorespiratory fitness and other kinds of conditioning needs an understanding of the changes that occur as aerobic or anaerobic efficiency improvements.

General metabolism rises, muscle metabolism improves, haemoglobin rises, bloodstream buffers raise, venous return improves, stroke volume improves, and the  blood bed becomes more adaptable to varied demands as aerobic/anaerobic capacity rises.

Each of these cardiovascular fitness/cardiorespiratory conditioning results will have a major effect on muscular strength.
