摘要

电动自行车现在不仅用于通勤,还用于运动、康复和工作。骑行者通过调节助力和传动装置来应对不同的条件,并达到所需的身体负荷。由于速度更快、响应时间更短以及条件各异,骑行者、自行车和环境之间的这种互动可能会变得复杂,从而可能导致不适。一项针对 21 名非运动员的研究探讨了在 66 个不同坡度阻力的模拟室内骑行过程中,骑行者如何管理电动自行车的物理负荷。参与者控制电动自行车以保持中等强度,并收集了有关电动自行车控制潜伏期、控制次数、可接受的踩踏功率、心率和感知消耗的数据。平均而言,骑行者在坡度变化后 5.3 秒进行控制调整,并使用 2.7 次控制尝试达到可接受的踩踏功率。研究发现,在不同的坡度上,最可接受的踩踏功率是相似的,这表明首选负荷是一致的。参与者的目标是在受到外部干扰的情况下保持稳定的踩踏功率,达到中等运动强度(最大心率为 66.9%,感知用力率为 12.1)。研究结果表明,可以估算出个人的首选负荷,这可以为今后在参与式人体工程学中保持这种负荷和改善电动自行车骑行体验的研究提供参考。

Optimizing E-bike controls for human-bike interaction to enhance riding experience and efficiency
E-bikes are now used for sports, rehabilitation, and work, not just commuting. Riders adjust power assistance and transmission to handle different conditions and reach their desired physical load. This interaction between the rider, bike, and environment can become complex due to faster speeds, shorter response times, and varying conditions, potentially leading to discomfort. A study with 21 non-athletes explored how riders manage the physical load on e-bikes during a simulated indoor riding session with 66 stages of varying slope resistance. Participants controlled the e-bike to maintain a moderate intensity, and data on latency of e-bike control, number of controls, acceptable pedaling power, heart rate, and perceived exertion were collected. On average, riders made their control adjustment 5.3 s after a slope change and used 2.7 control attempts to reach an acceptable pedaling power. The study found that the most acceptable pedaling power were similar across different slopes, suggesting a consistent preferred load. Participants aimed to maintain stable pedaling power despite external disturbances, targeting a moderate exercise intensity (66.9% maximal heart rate and a rate of perceived exertion of 12.1). The findings indicate that it's possible to estimate a personal preferred load, which could inform future studies on maintaining this load and improving the e-bike riding experience in participatory ergonomics.
