abstract="Analysis of metabolic gas exchange and muscular output measures have enabled researchers to index activity intensity and energy expenditure for a myriad of  exercises. However, there is no current research that investigates the physiological  demands of riding electrically powered skateboards. The aim of this study was to  measure the energetic cost and muscular trends of riding a novel electrically  powered skateboard engineered to emulate snowboarding on dry-land. While riding the  skateboard, eight participants (aged 21-37 years, 1 female) donned a portable  breath-by-breath gas analyzer to measure energy expenditure (mean = 12.5, SD = 2  kcal/min), maximum heart rate (mean = 158, SD = 27 bpm), and metabolic equivalent  (mean = 10.5, SD = 2 kcal/kg/h). By comparison, snowboarding has a metabolic  equivalent (MET) of 8.0. Per the Compendium of Physical Activities guidelines, the  predicted MET values for riding an electrically powered skateboard qualifies as  vigorous-intensity activity. Four participants additionally wore a surface EMG  embedded garment to record the percentage of maximum voluntary contraction (%MVC) of  lower limb muscle groups. The inner quadriceps had the most pronounced mean peak  muscle activation of 145%MVC during frontside and 164%MVC during frontside turns. EMG recordings showed 11.7%MVC higher utilization during backside turns compared to  frontside turns while riding the electrically powered skateboard, which is similar  to trends observed in alpine snowboarders. Therefore, electrically powered  skateboards may be a promising technology for snowboarders and non-snowboarders  alike to burn calories and increase physical activity year-round.<p /> <p>Language: en</p>",
