Step 1
Let's analyze each option: * **Talk test:** This is a simple and practical method to gauge exercise intensity. If you can talk comfortably, your intensity is likely moderate. If you can only speak a few words at a time, it's vigorous. If you can't talk at all, Show more…

In a stress test for elite athletes, a physical system is used to measure the performance of the individual. Indicate which of these signals are analog signals: Temperature ⇒ Type: Temperature, Range: from 18ºC to 22ºC (only integer and half-integer values are measured) O2 Saturation ⇒ Type: Voltage, Range: [1-5 mV] Performance ⇒ Type: Real number; Range: [0-1] VO2 ⇒ Type: Liters/minute; Range: [2-7.5 l/min] Respiratory Rate ⇒ Type: Numerical; Range: integers from 8 to 40 Activity level (accelerometer) ⇒ Type: Current, Range: [0-7 mA]

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 (VO2) = 0.068*(age) + 0.064*(HR) + 0.026*(time) + 6.071. If a person is 50 years old, blood pressure of 132 bpm, and a walking time of 15 minutes, what is his/her expected maximum oxygen uptake?
