Answer:
The correct answer is option D, that is, aerobic.
Explanation:
The aerobic fitness signifies a measure of the tendency of the body to take oxygen from the atmosphere and utilize it to generate energy for the cells of the muscles. Various elements affect aerobic fitness like cardiac function, the efficiency of the lungs, genetic makeup, and gender age.
Aerobic fitness refers to the tendency of the body to use and transport oxygen. It is determined by VO2 max, that is, the maximum concentration of oxygen one can utilize at the time of intense exercise. VO2 max is affected by both primary and secondary constituents. The primary component comprises the tendency of the heart, lungs, and the vascular system to deliver oxygen to the muscles through the bloodstream.
While the secondary constituents comprise the tendency of the cells of the muscles to extract oxygen from the blood and utilize it to produce ATP, the energy currency of the cells.
