Further evidence is emerging that e-scooters are far from being active transport and, if used extensively, can actually be harmful to health.
Scientists at the University of Kent in the UK have for the first time measured the energy expenditure of riders in a controlled laboratory setting by analysing gases in the breath.
This study compared a 15-minute bout of e-scooter riding to time-matched resting and walking conditions, using a treadmill.
The study used the MET (metabolic equivalent task) standard method to assess activity level as well as measuring the subjective experience of post-walking and e-scooter conditions.
The study revealed that walking at a pace of 4.8km/h on a treadmill without incline expended 3.7 METs (a moderate intensity activity) while riding an e-scooter on a treadmill at 12km/h expended 1.6 METs (a light intensity activity), not a great deal more effort than the 1.0 MET expended by lying down.
This suggests riding an e-scooter expends fractionally greater METs than driving a car and riding public transport (1.3 METs) but less than conventional cycling (8 METs) and e-bike riding (4–7 METs).
"Based on the findings presented here, we support the notion that acute e-scooter use cannot be considered to elicit health benefits and is not active travel,” the researchers said.
"As such, prolonged and frequent use of e-scooters as an alternative to active transport could result in a decline in physical activity, be detrimental to long-term public health and therefore not be recommended.
"Increasing electric micro-mobility transport infrastructure appears counterproductive within a health agenda, especially as recognised active transport has been linked to health-enhancing physical activity for over 20 years.
"The gap between existing transport provision and the first–last mile, connecting traditional public transport to end destination, presents an ideal opportunity to promote active transportation,” they concluded.
Bicycle Network previously reported on similar findings from the University of University of Tennessee.
