Following on their e-bike physical activity work, LEVER researchers Cherry, Wen, and Bassett are setting out to identify the level of physical activity of e-scooter users. They followed a similar approach to their earlier e-bike study. Here, they directly measure ventilation rates (using a Cosmed Fitmate) while riding a scooter, walking and driving the same course as the previous study. In addition, they conducted a fixed-maneuver trial of muscle activity on each mode using an EMG device, assessing activity of 15 muscle groups. As expected, scooter riding metabolic activity seems to fall between walking and driving. Upper limb and trunk muscle groups are higher for scooter riding than other modes.
