The Effect Of Elbow Flexion Speed And Partial Limb Occlusion On Emg Activity, John Sampson, Herbert Groeller, Darryl Mcandrew, R Achttien, J Stege

Darryl J McAndrew

This investigation aimed to determine the neuromuscular response of the bicep brachii during heavy (6RM) dynamic resistance exercise performed to volitional exhaustion. Electromyographic (EMG) activity was compared in twelve male subjects performing dominant-limb elbow flexion exercise during four conditions: i) Explosive concentric and eccentric (SSC); ii) Explosive concentric, control eccentric (EC); iii) control (C); and iv) control with limb occlusion (CO) (110mmHg). CO and SSC are reported to increase motor unit activity when compared to control exercise (2 second flexion, 2 second extension). It was hypothesised that EMG activity will be higher in conditions of explosive exercise. Surface EMG activity …
