Question

What does cardiorespiratory fitness measure?

Answer 1

VO2 max is considered to be the most valid measure of cardiorespiratory fitness. It measures the capacity of the heart, lungs, and blood to transport oxygen to the working muscles, and measures the utilization of oxygen by the muscles during exercise. One way to test is using the Rockport Fitness test.

Answer 2

Cardiorespiratory fitness (CRF) is responsible for assessing the ability of the respiratory and circulatory systems to provide sufficient oxygen to the skeletal muscles during prolonged physical activity.

Explanation:

It is proven that physical activity are very effective in order to increase cardiovrespiratory fitness. The primary measure of CRF is VO2 max.

There are several advantages of cardiorespiratory fitness that includes:

1. It can reduce several risks related to lungs and heart such as lung cancer and stroke.
2. Cardiorespiratory fitness  also improves functioning of lungs and heart condition.
3. CRF is potentially a stronger mortality indicator than other known risk factors such as smoking, high blood pressure, high cholesterol and type 2 diabetes.
4. CRF can also help to improve risk prediction validity and can modify traditional risk factors.
