Cycling is one of the most practiced sports in the world, both professionally and an amateur level.

Epidemiological studies have shown that cycling is an activity with a high incidence of overuse injuries and is a sport with the highest absolute number of accidents per year, followed by basketball and football. The study of the cyclist's posture during pedal stroke is crucial in order to better identify not only the biomechanical factors limiting the performance but also those predisposing to the injury. Abnormalities in pelvic movements during cycling are related to improper bicycle fit and related pathologies. Through a Motion Capture System, the gold standard in evaluating biomechanical parameters in sport performance, our purpose aims to investigate the differences in pelvis kinematics during the different phases of the crank cycle.Ten (10) healthy experienced cyclists were collected at different pedaling rates: lower (60 bpm), middle (90 bpm) and higher (120 bpm). Each athlete used his own race bike positioned on a professional cycletrainer. After recording the data, we extrapolated the kinematic parameters of the pelvis. Through statistical analysis we compared the three different pedaling conditions. Our results showed that the lowest swing in the pelvis occurs at 90 rpm. Although this pedaling rate is not the lowest, it represents the safest for injuries’ prevention and the most comfortable for the cyclist. Motion capture is therefore a valuable tool for analyzing the kinematics of the pedaling cycle.

Abstract

Cycling is one of the most practiced sports in the world, both professionally and an amateur level. Cycling for many kilometers in a training session puts the body under severe metabolic and biomechanical stress. Epidemiological studies have shown that cycling is an activity with a high incidence of overuse injuries and is a sport with the highest absolute number of accidents per year, followed by basketball and football. The study of the cyclist's posture during pedal stroke is crucial in order to better identify not only the biomechanical factors limiting the performance but also those predisposing to the injury. Abnormalities in pelvic movements during cycling are related to improper bicycle fit and related pathologies. Through a Motion Capture System, the gold standard in evaluating biomechanical parameters in sport performance, our purpose aims to investigate the differences in pelvis kinematics during the different phases of the crank cycle.Ten (10) healthy experienced cyclists were collected at different pedaling rates: lower (60 bpm), middle (90 bpm) and higher (120 bpm). Each athlete used his own race bike positioned on a professional cycletrainer. After recording the data, we extrapolated the kinematic parameters of the pelvis. Through statistical analysis we compared the three different pedaling conditions. Our results showed that the lowest swing in the pelvis occurs at 90 rpm. Although this pedaling rate is not the lowest, it represents the safest for injuries’ prevention and the most comfortable for the cyclist. Motion capture is therefore a valuable tool for analyzing the kinematics of the pedaling cycle.
