However, there are several reports regarding sports injury in cycling, including knee pain, quadriceps tendonitis, stress fracture and foot disease. The causes to induce injuries might be improper cycling posture, insufficient warm-up and overuse. Therefore, the objective of this study was to measure the biomechanics parameters during seated on a stationary cycling. This study developed the force and torque measuring system for recording three-dimensional forces and moments on the pedal. First of all, a material compression test machine was used to validate the pedal system. Also, the kinematics and kinetics of the lower limbs during the ACSM sub-maximal bicycle test were evaluated. This study have been developed and validated a bicycle pedal measuring system for the kinetics of lower extremity, and the experimental results of human motion analysis showed that the peak knee flexion moment was 0.5 Nm/Kg, and the peak knee extension moment was 0.13 Nm/Kg. The results were very similar to previous studies, indicating that the developed pedal can accurately measure force and moment of lower extremity. In the future, this system and the model would help coaches and athletes to prevent bicycle injuries and increase the efficiency of bicycle training. And the relevant results could be widely used in various styles of indoor and outdoor cycling.859893 bytesapplication/pdf固定式腳踏車; 運動學; 動力學Stationary cycling; Kinematics; Kineticsreport
