The aim of this study was to compare the intervals of time between adjacent zero crossings (ZCI), an alternative frequency-temporal parameter, with the root-mean-square (RMS) value and the median frequency (Fmed) from the surface EMG (sEMG) signal in muscle fatigue analysis. Twenty right-handed volunteers performed isometric contractions of right biceps brachii muscle while sEMG signals were collected...
Resistance exercise is essential to improve or maintain muscle performance. Vibration training has been suggested as an alternative option for muscle conditioning, aiming especially at improving muscle strength and power. Several studies link the effects of vibration training to enhanced neuromuscular stimulation, measured by electromyography (EMG) and typically ascribed to involuntary reflex mechanisms...
We investigated muscle activation levels or patterns determined during two-joint arm movements. Twelve subjects were instructed to move their right (dominant) wrists in a horizontal plane. Surface electromyographic activities were recorded from the brachioradialis, biceps brachii, and triceps brachii. The muscle activation level was demonstrated as a function of both the elbow and shoulder torque...
