The reliability of electromechanical delay during squat jump

Original language description

EMD as a factor influencing the speed of muscle force production, measured during squat jump, can be used as a relevant substitution for isometric or isokinetic assessment. The purpose of this study was to examine the reliability of measurement of EMD in knee muscles (biceps femoris, semitendinosus, rectus femoris) during a vertical jump. Thirteen volunteers unfamiliar with the squat jump participated in this study and were measured 2 times, with rest periods of 7 days between measurements. EMD was calculated using a force platform and electromyography. Intraclass correlation coefficients ranged (ICC) from 0.69 to 0.78, indicating high reliability for the rectus femoris (RF) and semitendinosus (ST) and moderate reliability for the biceps femoris (BF). Absolute reliability expressed by standard error of the measure (SEM) ranged for RF 28.11, BF 23.18 and ST 21.20, better used as a coefficient of variation (CV of SEM) for RF 22.81%, BF 25.19% and ST 19.72%. These findings provide researchers and clinicians with another method for relatively fast measurement of EMD using portable devices.
