A 45 year old female (145 lbs body weight) completed two stages (300 kgm/min and 600 kgm/min) of a submaximal cycle ergometer test. Her steady state heart rate for stage 1 = 140 bpm. Her steady state heart rate for stage 2 = 165 bpm. Knowing predicted Max VO2 = m(HRmax – HR2) + VO22 where m(slope) = (VO22 – VO21)/(HR2 – HR1); Calculate this persons predicted Max VO2. Hint: You must know the oxygen cost (VO2) for each workload. Cycle Ergometer Metabolic Equation: VO2 (ml/kg/min) = [(1.8 * work rate) / Body weight] + 7
A. 21.59 ml.kg-1 min-1
B. 24.15 ml.kg-1.min-1
C. 26.67 ml.kg-1. min-1
D. 19.78 ml.kg-1.min-1
E. Not enough information is given to calculate predicted Max VO2
