Force needed to perform cycling is produced mostly by quadriceps muscles. However, previous studies have shown that the use of hamstring muscles increases the cycling performance. Cleat pedals facilitate the use hamstring muscles during cycling, however, have a safety problem of difficulty in detaching feet from the pedals. The purpose of this study was to create a new pedal that maintains the benefits of already existing cleat pedals while improving the safety. After 38 minutes of cycling, muscle fatigue was compared between the new pedals and flat pedals by analyzing the electromyographic signals of major lower limb muscles and the maximal performance rpm(MPR). Percentage decrease in MPR after cycling was found to be similar between the two pedals (6.8% for new pedal and 8.0% for flat pedal). However, the new pedal has shown better performance than the flat pedal as the MPR of the new pedal was higher (145 rpm for new pedal and 137 rpm for flat pedal). Also for the same rpm during cycling, the power ratio between new pedals and flat pedals showed that new pedals are more effective (Rectus Femoris 89%, Biceps Femoris 68%, Gastrocnemius 31%, Tibialis Anterior 47%).
