Abstract
The aim of the study was to develop a motion analysis system to evaluate relations between the patella movements, activation muscles of the lower limb and pedal force during the pedaling motion. Four cyclists performed for 20 seconds at two pedaling rates (110-120 rpm and 80-90 rpm). The patella movements during the pedaling motion were measured using a camera motion capture system to track reflective markers. The value of surface electromyography (EMG) was measured by electrodes from the tensor of latae (TFL), vastus lateralis (VL), rectus femoris (RF), hamstrings (HAM) and gastrocnemius (GAS). Furthermore, the measurement of pedal force was conducted by a power meter (Pioneer Inc.). The developed analysis system, along with the measurements of the patella movement, EMG and pedal force, could evaluate the pedaling motion quantitatively.
