Abstract
PURPOSE: The purpose of this investigation was to determine if there was a relationship between VO2peak measured during a graded maximal treadmill test using the Bruce Protocol and a graded maximal CPR compression test. METHODS: Fifteen male subjects (age 23 +/- 4 yrs; body mass: 81.06 +/- 11.40 kg; BMI: 25.86 +/- 3.03 kg/m2) underwent the following conditions: 1) Incremental Work Test (IWT) using a CPR simulator. The cadence of CPR compressions was increased every 30 sec until volitional fatigue 2) Treadmill VO2max (TM): incremental maximal oxygen consumption test using the Bruce Protocol. During all conditions oxygen consumption (VO2) and Heart Rate (HR) were measured using a Parvo-Medics True One 2400 Metabolic Measurement System (Sandy, Utah). RESULTS: The VO2peak measured during maximal graded treadmill testing using the Bruce Protocol averaged 38.13 ml/kg/min +/- 5.98. The VO2peak measured during maximal graded CPR compression testing averaged 14.76 ml/kg/min +/- 3.46. No relationship was observed between VO2peak measurements of graded maximal treadmill testing and graded maximal CPR compression testing (R = 0.87; p =.768). CONCLUSIONS: No relationship existed between VO2peak measured during graded maximal treadmill testing using the Bruce Protocol and VO2peak measured during graded maximal CPR compression testing. Aerobic power capabilities during CPR performance appear to be mode specific.
