Research on how human balance and control bicycles are inconclusive, largely due to the small number of participants in the previous studies. Therefore, the aim of this study was to test the hypotheses that 1) cycling lateral deviation amplitude will reliably show differences between more and less experienced cyclists and 2) more experienced will exhibit slower and smaller steering motions compared to the less experienced cyclists. Twenty-eight experienced and inexperienced cyclists rode a bicycle in a straight line. Lateral deviation, steering and roll were measured. Intersession reliability of the deviation was high with Cronbach's alpha values higher than 0.75. The amplitude, variability and rate of steering and roll parameters showed statistically significant differences between the groups. The test used in this study is sensitive to detect differences between more and less experienced cyclists and can be used for further research that aims to test the effect of a specific intervention addressing rider control. We also showed that steering and roll angle, which were described before as two of the main motor control actions in bicycle control, differ in the variability, amplitude and rate between more and less experienced cyclists. The results of the present study have practical implications for improving bicycle rider control and increasing the safety of cyclists.
关于人类如何保持平衡以及操控自行车的研究尚无定论，这主要是由于之前的研究参与者数量较少。因此，本研究的目的是检验以下假设：1）骑行时的横向偏差幅度能够可靠地显示经验丰富和经验不足的骑行者之间的差异；2）与经验不足的骑行者相比，经验丰富的骑行者转向动作会更慢且幅度更小。28名经验丰富和经验不足的骑行者沿直线骑行。测量了横向偏差、转向和侧倾。偏差的组内信度较高，克朗巴哈系数值高于0.75。转向和侧倾参数的幅度、变异性和速率在两组之间显示出统计学上的显著差异。本研究中使用的测试对于检测经验丰富和经验不足的骑行者之间的差异很敏感，可用于进一步研究旨在测试特定干预措施对骑行者操控影响的研究。我们还表明，之前被描述为自行车操控中两个主要运动控制动作的转向和侧倾角，在经验丰富和经验不足的骑行者之间的变异性、幅度和速率有所不同。本研究结果对于改善自行车骑行者的操控以及提高骑行者的安全性具有实际意义。
