Calibration Variability of 15 High Use Life Fitness Cycle Ergometers

Abstract

The US Navy uses the Life Fitness 95 CI Classic and the Life Fitness 95C Version 4 cycle ergometers as a cardio testing alternative to the 1.5 mile run. The cardio alternative test involves a maximum calorie burn in 12 minutes. Although both of these ergometers have been validated for calorie burn accuracy, the variability from one ergometer to the next, as well as the long term stability of the calibration of the ergometers is not known. Fifteen high use (679-4938 hours) Life Fitness 95 CI Classic and the Life Fitness 95C Version 4 cycle ergometers were assessed using a vacuumed Ergometer Calibrator. The ergometers were driven for 10 minutes at 100, 200, and 300 watts and the calories burned as displayed on the ergometer display was recorded. The indicated calories burned reported at 100, 200, and 300 watts were 71.53 plus or minus 3.7, 129.67 plus or minus 3.87, and 191.60 plus or minus 4.31 Kilocalories respectively.
