In cycling, proper saddle height is important because it contributes to the mechanical work of the lower limb joints, thus altering pedaling efficiency. The appropriate method to select optimal saddle height is still unknown. This study was conducted to compare a static (anthropometric measurements) vs. a dynamic method (2D analysis) to adjust saddle height. Therefore, an examination of the relationship between saddle height, anthropometrics, pedaling angles, and hamstring flexibility was carried out. Saddle height outside of the recommended range (106-109% of inseam length) was observed in 56.5% of the subjects. Inappropriate knee flexion angles using the dynamic method were observed in 26% of subjects. The results of this study support the concept that adjusting saddle height to 106-109% of inseam length may not ensure an optimal knee flexion (30-40°). To solve these discrepancies, we applied a multiple linear regression to study the relationship between anthropometrics, pedaling angles, and saddle height. The results support the contention that saddle height, inseam length, and knee angle are highly related (R = 0.963, p < 0.001). We propose a novel equation that relates these factors to recommend an optimal saddle height (108.6-110.4% of inseam length).
在自行车运动中，合适的鞍座高度很重要，因为它有助于下肢关节的机械工作，从而改变蹬踏效率。选择最佳鞍座高度的合适方法仍不清楚。本研究旨在比较静态（人体测量）与动态方法（2D 分析）来调整鞍座高度。因此，对鞍座高度、人体测量、蹬踏角度和腘绳肌灵活性之间的关系进行了检查。研究中观察到 56.5%的受试者的鞍座高度超出了推荐范围（内腿长的 106-109%）。使用动态方法观察到 26%的受试者的膝关节屈曲角度不合适。本研究的结果支持这样一种观点，即调整鞍座高度至内腿长的 106-109%可能无法确保最佳的膝关节屈曲度（30-40°）。为了解决这些差异，我们应用多元线性回归来研究人体测量、蹬踏角度和鞍座高度之间的关系。结果支持这样一种观点，即鞍座高度、内腿长和膝关节角度高度相关（R = 0.963，p < 0.001）。我们提出了一个新的方程，将这些因素联系起来，以推荐最佳的鞍座高度（内腿长的 108.6-110.4%）。
