Cardiorespiratory fitness is most likely to improve due to which of the following types of exercise? A. bicycling B. weight lifting C. push-ups D. sit-ups Please select the best answer from the ch


The correct answer is A. bicycling


The ability of lungs and heart to supply sufficient oxygen for the working muscle during an extended period of aerobic activity is called cardiorespiratory fitness.

Aerobic exercise is the best exercise that can help in improving cardiorespiratory fitness. Aerobic exercise helps in increasing cardiorespiratory fitness because during aerobic exercise the respiratory rate and heart rate enhances.  

Bicycling is one of the best aerobic exercises by which we can improve our cardiorespiratory fitness. Therefore the correct answer is A.






Aerobic exercise like running, jogging or swimming.

Cardiorespiratory fitness is most likely to improve due to (A) bicycling.

Further Explanation:

Cardiorespiratory fitness is the ability of the lungs to convert the deoxygenated blood to oxygenated blood. The heart to pumps oxygenated blood to the cells that need oxygen and increases the ability of the muscles to produce energy. The delivery of oxygen in the working muscles can be affected by factors such as stroke volume, cardiac output, heart rate etc. Participation in activities that help in energy build up like jogging, bicycling etc. can increase the heart rate. Thus, increasing the cardiovascular fitness. The heart rate increases followed by increase in the oxygen rich blood into the cells that need oxygen.

Bicycling is categorized as a type of aerobic activity. Bicycling for 30 minutes or more can strengthen the muscles of the heart and also the ability of the lungs to convert deoxygenated blood into oxygenated blood. The consistency in such activities can improve the cardiorespiratory fitness. Weighttraining is the common type of exercise that can develop the skeletal muscle's size as well as strength. The force of gravity from the weighted bars is utilized and the force that opposite the force of gravity is used by the muscles for strength as well as increasing the size of the skeletal muscle. Push-ups and sit-ups are the form of exercise that uses the persons on body weight to strengthen the muscles involved in the push up. The chest muscles, abdominals, triceps, biceps, forearms etc. are involved in the push-ups.

Thus, cardiorespiratory fitness is most likely to improve due to bicycling.

The cardiorespiratory fitness can be improved by bicycling.


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.

Cardio-respiratory fitness, respiratory system, circulatory system, blood pressure, stamina, physical activity, jogging, running, cycling, hiking, walking, lungs, heart.

The correct answer would be, Bicycling.

Cardiorespiratory fitness is most likely to improve due to Bicycling.


During a physical activity like running, jogging, or doing workouts involving cardiovascular activities, the circulatory and respiratory systems of the body provide oxygen to the skeletal muscles.

Bicycling is an exercise due to which the cardiorespiratory fitness is improved.

When oxygen reaches the muscles, the risk of cardiovascular disease is decreased. Also the body is able to do larger muscle exercises due to increased flexibility, and the efficiency of the respiratory system also increases.

But more blood is pumped through the body due to cardiorespiratory activities is not the benefit of doing the physical activities.
