Evaluation of energy expenditure on the Woodway curve treadmill

Abstract

This study was designed to 1) compare the caloric expenditure values displayed on the Curve's console to directly measured values, and 2) if there was a significant difference between displayed and measured values, to develop a regression equation to more accurately predict energy expenditure on the Curve. Fifty-five volunteers (27 male and 28 female) walked or ran on the Curve treadmill at four different speeds (between 2-8 mph) for five minutes at each speed. The caloric expenditure values displayed on the Curve's console were recorded and compared to measured calories using a Jaeger Oxycon portable metabolic analyzer. Across the speeds tested, the Curve console systematically overestimated measured caloric expenditure by 67-117%.
