Write the Fick equation used to compute VO2 using the following format by filling in the correct terms for A, B, and C: VO2 = (A × B) × C. Use the Fick equation as the basis for your explanation of the following scenario. Bill is a well-trained competitive bicyclist. His VO2 max performed on a progressive bicycle test is 73 ml·kg-1·min-1, and his VO2 max performed on a progressive running test is 62 ml·kg-1·min-1. Bob is a well-trained runner. His VO2 max performed on a progressive running test is 75 ml·kg-1·min-1, and his VO2 max performed on a progressive bicycle test is 64 ml·kg-1·min-1. Explain, using the Fick equation as the basis, the significant difference in the VO2 max values for both Bill and Bob when using a bicycling test versus a running test.

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) = 0.062*(age) + 0.118*(HR) - 0.02*(time) + 5.381. If a person is 27 years old, blood pressure of 112 bpm, and a walking time of 15 minutes, what is his/her expected maximum oxygen uptake?

Cardio-respiratory health is widely recognized as an important component of general physical well-being. Direct measurement of maximum oxygen inhalation (VO2 max) is the best individual measurement, although it is slow and expensive, so a prediction equation from other measurements that is easy to determine is desired. Consider the variables: y = VO2 max (L/min) x1 = weight (kg) x2 = age (years) x3 = time needed to walk one mile (min) x4 = heart rate (beats per min) y = 6 + 0.69x1 - 0.05x2 - 0.08x3 - 0.01x4 What is the expected value of the maximum oxygen inhalation with 84 kg of weight, 23 years of age, 8 minutes of walking, and a heart rate of 130 beats/min? Round your answer 0.XX to two decimal places.
