Effects of muscle fatigue and temperature on electromechanical delay.
The effect of repeated maximal isometric knee extensions on electromechanical delay (EMD) and associated muscle temperature changes were investigated on seven college aged subjects. The exercise produced a significant reduction in muscle contraction force, rate of force development and muscle conduction velocity, whilst the muscle temperature increased by 2.1 degrees C. The EMD increased from a...
متن کاملInfluence of Passive Muscle Tension on Electromechanical Delay in Humans
BACKGROUND Electromechanical delay is the time lag between onsets of muscle activation and muscle force production and reflects both electro-chemical processes and mechanical processes. The aims of the present study were two-fold: to experimentally determine the slack length of each head of the biceps brachii using elastography and to determine the influence of the length of biceps brachii on e...
متن کاملInfraspinatus Electromechanical Delay on Shoulder Instabilities
Shoulder instability is a major complaint in overhead athletes. The shoulder joint stability is provided mainly by rotator cuff muscles. The Electromechanical Delay (EMD) may be an important parameter in the responsiveness of a muscle. The aim of this study was to measure and compare the infraspinatus EMD in healthy and unstable shoulders and in dominant and non-dominant shoulders. We did not f...
متن کاملThe Effect of Bronchial Asthma on Interatrial Electromechanical Delay Coupling Obtained Using Tissue Doppler Imaging
Background: Asthma is a predisposing factor for the development of atrial fibrillation. Asthma disturbs the electrophysiology in the right and left atrium. The aim of this study was to evaluate atrial electromechanical delay by coupling obtained from tissue Doppler imaging (TDI) in children. Methods: A cross-sectional study was conducted on 50 patients with Bronchial Asthma, compared with 50 hea...
متن کاملDetection of the electromechanical delay and its components during voluntary isometric contraction of the quadriceps femoris muscle
Electromechanical delay (EMD) was described as a time elapsed between first trigger and force output. Various results have been reported based on the measurement method with observed inconsistent results when the trigger is elicited by voluntary contraction. However, mechanomyographic (MMG) sensor placed far away on the skin from the contracting muscle was used to detect muscle fiber motion and...
