The contentious question of whether electric mountain bikes (e-MTBs) require physical exertion comparable to their conventional counterparts has received fresh empirical insight. A recent investigation, detailed in the scientific periodical Retos, scrutinized the physiological variations experienced by riders switching between traditional mountain bikes and e-MTBs. The study meticulously measured parameters such as heart rate, power output, and subjective perceived exertion under authentic trail conditions.
Helmed by Professor Juan Carlos Redondo Castán from the University of León, the research team also included specialists from the University of Valladolid and the Universidad Europea Miguel de Cervantes. Over a span of 16 weeks, the team conducted extensive fieldwork on mountainous terrains, deliberately moving away from controlled laboratory environments to capture genuine responses during recreational cycling.
Influence of Terrain and Assistance Level on Physiological Metrics
The core findings reveal that the degree of electrical assistance provided by the e-bike, alongside the nature of the terrain, significantly modulates the rider’s cardiovascular and muscular exertion. Unlike prior assumptions that e-bikes might undermine physical effort, the data demonstrate a nuanced interaction wherein assistance levels adjust power output and heart rate variably depending on route difficulty.
The measured heart rates were not uniformly diminished when riding the e-MTB; rather, they fluctuated in response to the terrain’s demands and the assistance settings chosen by the riders. Similarly, power output, a critical indicator of muscular work, showed complex patterns that correlated with the electrical support and environmental challenges encountered along the trails.
This comprehensive field study, with its rigorous methodology and real-world applicability, adds a significant layer of nuance to the ongoing discourse about e-bikes’ impact on physical performance. The interdisciplinary approach, combining expertise from multiple Spanish universities, ensures robust analysis and credible conclusions backed by empirical evidence.
