Using a simple biomechanics model, the human heart rate is expressed as HR = 70 + 0.8W, where W is the workload in watts. If the workload increases by 50 watts from a baseline of 70 bpm, what is (a) the predicted change in heart rate and (b) the heart rate at 150 watts?
A 50-watt increase yields an HR increase of 0.8*50 = 40 bpm. At 150 watts, HR = 70 + 0.8*150 = 70 + 120 = 190 bpm.
