Question

Cardiorespiratory fitness is widely recognized as a major component of overall physical well-being. Direct measurement of maximal oxygen uptake (VO2max) is the single best measure of such fitness, but direct measurement is time-consuming and expensive. It is therefore desirable to have a prediction equation for VO2max in terms of easily obtained quantities. A sample is taken and variables measured are age (years), time necessary to walk 1 mile (mins), and heart rate at the end of the walk (bpm) in addition to the VO2 max uptake. The equation from a multiple regression is (V02) = 0.087*(age) + 0.216*(HR) - 0.046*(time) + 1.613. If a person is 43 years old, blood pressure of 123 bpm, and a walking time of 15 minutes, what is his/her expected maximum oxygen uptake?

Explanation / Answer

Given a person is 43 years old, blood pressure of 123 bpm, and a walking time of 15 minutes,

Maximum oxygen uptake = (0.087 * 43) + (0.216 * 123) - (0.046 * 15) = 29.619.

Hence, Option (4) is the correct choice. (Ans).
