Which of the following decreases as the result of cardiorespiratory training? ?

B.)Resting heart rate

Explanation:

Cardiorespiratory fitness refers to the ability of the body's circulatory and respiratory systems to supply blood that are rich in oxygen to skeletal muscles during sustained physical activity.

By observing regular exercise, the system of the body become more efficient which could result to enlargment of the heart muscle, increament in the number of small arteries in trained skeletal muscles that supply more blood to all the all muscles in action enablement of

blood to be pumped with each stroke.

During exercise,not only the respiratory system is improved but the heart beat rate is also improved by increasing the amount of oxygen that is inhaled and distributed to all the body tissue.Below are different benefits of cardiorespiratory fitness;

1.)Cardiorespiratory fitness brings about improvement in lung and heart condition.

2.)It brings reduction in the risk of heart disease and lung cancer,
