BIOMECHANICS OF BICYCLE PEDALLING
AbstractFive pedalling conditions were investigated for three test subjects using a six load component pedal dynamometer. EMG electrodes simultaneously monitored the activity of eight leg muscles. Both pedal dynamometer and EMG data were digitized by a minicomputer. A five-bar linkage model of the leg-bicycle system was used to calculate the joint moments of the leg. Data analysis entailed generating plots of joint moments due to pedal load only and acceleration only. Total moments were produced by superimposing the two moment histories . The separate moment histories, together with the pedal forces and IEMG results, enable a detailed picture of the biomechanics of bicycle pedalling.
