The cardiorespiratory fitness can be improved by bicycling.

Explanation:

Cardiorespiratory fitness is known to be the ability of the respiratory systems as well as circulatory system to provide oxygen to the muscles at the time of sustained physical activity. Cardiovascular or aerobic exercise aids in elevating the energy as well as stamina, aids in managing the blood pressure, improves the lipid profile, and also helps in burning extra calories in order to maintain the optimum weight.

Cardiovascular exercise refers to any activity which includes the large muscles of the body, is continuous as well as rhythmic in nature, and also challenges the lung as well as heart to function harder. Activities such as walking, cycling, running, jogging, aerobics, stairs climbing, and hiking are known to be pure aerobic activities.

The relationship between cardiovascular fitness and other sections of conditioning needs a review of changes which takes place with elevated aerobic or anaerobic capacity. As this capacity elevates, the general metabolism also increases, the muscle metabolism is enhanced, the levels of hemoglobin also elevate, the buffers found in the blood flow also rises, venous return gets better, stroke volume is also improved, and the blood is more adaptable to varying demands.
