1. You conducted the YMCA cycle ergometer submaximal test on Katherine. Her exercise HR at the end of stage 1 was 108 bpm. She completed two additional stages with an exercise HR at the end of stage 2 of 133 bpm and stage 3 of 149 bpm. Estimate her maximum HR and 85% of estimated HRmax. Identify her work rate for stages 2 and 3 below with the appropriate units. Then, plot the appropriate HR values in the graph below and determine her estimated maximum work rate and VO₂max. Finally, convert the estimated absolute VO₂max identified from the graph to relative VO₂.
