Homework SourseAlpha performed a stepping exercise for 23 minutes onto a 16
Alpha performed a stepping exercise for 23 minutes onto a 16 inch box at a cadence of 108 bpm. Alpha weighs 225 lbs. Alpha\'s average net VO2 was 3.17 LO2/min and his average net VCO2 was 2.77 LCO2/min. Calculate Alpha\'s mechanical efficiency during this bout of exercise. Round your answer to the first decimal place.

Solution
Ans-
We want her heart beat to equal 120 so set the equation equal to that, her heart beat is already 50 bpm so thats a base we have to start off with, for every minute the heart rate increases by 5, so at one minute it will increase 5, at two minutes 10, etc...so that the increased heartbeat equals 5x.
2) 453.6 * 1/3= 151.2 grams. If 1 lb = 453.6 g, then multiply both sides by 1/3 to get your answer.
3) X gallons/second * 20 seconds=50 gallons
x= 2.5 gallons/second
Your flow rate is x gallons/second and you have 20 seconds to get fifty gallons.
