The Accelerometer Mmg Measurement Approach, in Monitoring the Muscular Fatigue
This research aimed to appreciate whether the mechanomyogram (MMG) may be used to monitor the muscle behavior under fatiguing exercise. The electromyogram (EMG) and MMG were simultaneously recorded from the Biceps and from the Brachioradialis muscles, with surface electrodes EMG, and accelerometer based transducers – MMG, from sixteen subjects. The conclusions are consistent in validating the u...
متن کاملDischarge characteristics of biceps brachii motor units at recruitment when older adults sustained an isometric contraction.
The purpose of this study was to compare the discharge characteristics of motor units recruited during an isometric contraction that was sustained with the elbow flexor muscles by older adults at target forces that were less than the recruitment threshold force of each isolated motor unit. The discharge times of 27 single motor units were recorded from the biceps brachii in 11 old adults (78.8 ...
متن کاملGender Effects in Surface Electromyographic Activity of the Biceps Brachii Muscle During Prolonged Isometric Contraction
The muscle activity, electromyographic (EMG) signal steadiness and relationships between the EMG signal and endurance time among males and females have long been investigated and continue to be a subject of controversy. The aim of this study was to explore the electromyographic effects on the biceps brachii (BB) muscle of male and female subjects during prolonged isometric contraction (for 90 s...
متن کاملLocalized Electrical Impedance Myography of the Biceps Brachii Muscle during Different Levels of Isometric Contraction and Fatigue
This study assessed changes in electrical impedance myography (EIM) at different levels of isometric muscle contraction as well as during exhaustive exercise at 60% maximum voluntary contraction (MVC) until task failure. The EIM was performed on the biceps brachii muscle of 19 healthy subjects. The results showed that there was a significant difference between the muscle resistance (R) measured...
متن کاملreproducibility of maximum voluntary isometric contraction in "empty can" position during surface electromyographic analysis of shoulder muscles
objective: due to the frequent use of surface electromyography as a tool for the study of muscle function, to accurately compare electromyographic data from different muscles and different subjects, it is necessary to normalize the integrated data obtained from each muscle. the most common normalization technique is the use of maximum voluntary isometric contraction (mvic) of a predetermined is...
