Brief Summary:
The effects of active commuting with an e-bike, as compared with a "classic" bike, on cardiorespiratory fitness and vascular health are largely unknown. To assess whether active commuting with an e-bike or a classic bike increases peak oxygen consumption (VO2peak) in untrained and overweight individuals.

Condition or disease Intervention/treatment Phase
Physical Activity Obesity Behavioral: Commuting to work Not Applicable

Detailed Description:
Riding an electrically assisted bicycle (e-bike) is thought to be suitable to increase physical activity in daily life, to promote health, and to increase cardiorespiratory fitness in normal-weight individuals. The positive effect of commuting to work by a normal bike on cardiorespiratory fitness has been shown to be an important predictor of cardiovascular mortality in previous studies. We thought to improve maximal oxygen uptake by commuting to work by e-bike vs. classic bike. Besides cardiorespiratory fitness we assessed arterial stiffness as brachial-ankle pulse wave velocity as an independent predictor of cardiovascular events and all-cause mortality.
