A Preliminary Study on Determination of Saddle Height by using Knee Angle Method During Maximal and Submaximal Pedaling
The purpose of this study was to identify the applicability of the knee angle method during submaximal (SUB)and maximal (MAX) pedaling, and to compare with the movement of hip and ankle joint. Six cyclists(age: 34.6±5.6years, height: 174.2±5.7cm, weight: 84.8±7.6kg, career: 15.8±9.2years) participated in this experiment. 3D motion analysis system was used to acquire the movement ofo lwer limb. Using these motion data, hip ,knee and ankle joint angle were calculated. To compare SUB and MAX pedaling pattern, knee joint angle, minimum angle and range of motion (ROM) of each joint were used. eRsult showed that the knee angle method can be applied regardless of changes of cadence, in other words, both knee angles were in the range from 25° to 35° suggested by knee angle method. There were significant differences in the timing of minimum ankle joint of MAX and those of SUB, but those were not directly related to the changes of the knee joint angle. To clarify those causes, it is necessary to perform further studyu sing ankle strategy for improving pedaling and preventing injury.
