The purpose of this study was to determine the metabolic equivalents (METs) for scooter exercise (riding a scooter, scootering) and to examine the energy expenditure and the heart rate response, so that the results can be used in health promotion activities. Eighteen young adults (10 males and 8 females) participated in scootering on a treadmill at three different speeds for six minutes each. Before, during, and after the exercise, pulmonary ventilation, oxygen uptake (VO₂), carbon dioxide product, respiratory exchange ratio (R), and heart rate (HR) were measured. These measurements kept steady states from the 3rd to 6th minute of each different speed session. The MET values acquired during scootering at 80 m·min⁻¹, 110 m·min⁻¹, and 140 m·min⁻¹ were 3.9, 4.3, and 5.0, respectively. Calculated using VO₂ (ml·kg⁻¹·min⁻¹)×[4.0+R], the energy consumption for scootering at each speed was 67.0±10.6, 73.3±10.2, and 84.8±7.9 cal·kg⁻¹·min⁻¹, respectively. The regression equation between scootering speed (X, m·min⁻¹) and VO₂ (Y, ml·kg⁻¹·min⁻¹) is Y=0.062X+8.655, and the regression equation between HR (X, beats·min⁻¹) and VO₂reserve (Y, %) is Y=0.458X−11.264. These equations can be applied to both females and males. Thus, scootering at 80 to 140 m·min⁻¹ might not be sufficient to improve the cardiorespiratory fitness of young male adults similar to the participants, but it may contribute many healthy benefits to most female adults and even male adults, and improve their health and fitness at the faster speeds.
