the saddle vertical force dramatically decreased, which may have triggered the sit-to-stand transition This spontaneous transition occurred at minimum saddle vertical force of about 1 N.kg -1 . Furthermore, the strong relationship between saddle vertical force and cycling power for a given pedaling cadence suggests that SSTP can be predicted. Non-optimal behaviors were observed around the power corresponding to SSTP by studying handlebar and pedal forces, suggesting that the spontaneous choice to rise in the standing position may be a solution to reduce these constraints. In addition, this study suggests that improving bike settings and considering the specificities imposed by high force pedaling on the whole body during training may improve cycling performance, Clinicians, researchers, and manufacturers trying to understand the etiology of groin injuries and erectile dysfunction associated with cycling (Bressel and Larson, 2003. ,
2010) should also consider the factors associated with saddle forces ,
