Metabolic Equivalents during Scooter Exercise

Abstract

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 (VO(2)), 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 VO(2) (ml.kg(-1).min(-1))x[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 VO(2) (Y, ml.kg(-1).min(-1)) is Y=0.062X+8.655, and the regression equation between HR (X, beats.min(-1)) and VO(2)reserve (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.

The physiological and perceptual responses of stand‐up paddle board exercise in a laboratory‐ and field‐setting

“…As expected, EE increased linearly with SUP stroke rate (Table 2), however, with research seldom investigating similar responses to fixed-or self-paced SUP exercise (whether in laboratory-or field-settings), we are unable to directly compare our results with existing EE SUP data. Nonetheless, similar EEs have been reported for recreational surfing (∼7 to 8 kcal min −1 [Meir, Lowdon, Davie, Geebng, & Victoia, 1991;Watsford, Murphy, & Coutts, 2006]) and scootering (3.8-6.4 kcal min −1 [Kijima, Arimoto, & Muramatsu, 2007;Willmott & Maxwell, 2019]).…”

The metabolic and physiological responses to scootering exercise in a field-setting

“…The five scootering speeds chosen were: 6.0, 7.5, 9.0, 10.5 and 12.0 km/hr, which equated to 100, 125, 150, 175 and 200 m/min in line with previous study methods and recommendations of faster speeds (Kijima et al, 2007). The participants completed scootering around a 100 m oval circuit, where experimenters provided pacing times for each stage of the trial.…”

“…Participation in scootering exercise has increased in popularity over the past two decades (Kijima et al, 2001(Kijima et al, , 2007 and may contribute to physical activity (PA) guidelines (e.g. 150-mins of moderate-intensity, 75-mins of vigorous-intensity or a combination thereof per week [O'Donovan et al, 2010;Departments of Health, 2011]), potentially improving cardiorespiratory fitness if scootering speeds (e.g.…”

“…exercise intensity) provide sufficient physiological stimulus (e.g. >65% of heart rate maximum [HRmax]) (Pollock et al, 1998;Kijima et al, 2001Kijima et al, , 2007Arimoto et al, 2002). However, active transport is reportedly declining internationally in children (Tremblay et al, 2014;Ridley and Olds, 2016) and the prevalence of sedentary lifestyles and physical inactivity among adolescents and young adults is increasing (Rey-López et al, 2008;Hallal et al, 2012).…”

“…Moreover, specific and incremental scootering speeds are required to quantify the metabolic responses in association with current PA guidelines. Consequently, Kijima et al (2007) reported the EE (67-85 cal/kg/min) and METs (3.9-5.0) for 10-mins scootering at speeds ranging 4.8-8.4 km/hr, and found these values correspond to moderate-intensity exercise for most healthy adults (O'Donovan et al, 2010;Departments of Health, 2011). However, whilst faster scootering speeds may help improve cardiorespiratory fitness, little ecological validity exists as current research regarding scootering has been confined to a motorised-treadmill, where differences in energetic cost may occur between laboratory and outdoor conditions (Jones and Doust, 1996), and thus further investigation is required.…”
