The objective of this study was to investigate the relationship between the rectified filtered electromyography (RFEMG) and force output from the quadriceps. The subjects consisted of 11 normal young students (3 males and 8 females) whose mean age was 19.9±0.9 years. RFEMG was obtained from the rectus femoris, vastus medialis and vastus lateralis during isometric contractions which are performed at 10%, 30%, 50% and 70% of maximal voluntary contraction (MVC) at 90° knee flexion angle. Relative values of the RFEMG in each muscle were calculated (%RFEMG) and were compared with other at four submaximal voluntary contractions. The %RFEMG of the vastus lateralis was signifi¬cantly higher than that of the rectus femoris at 10% MVC, whereas no significant differences among three muscles were found at 30%, 50% and 70% MVC.
