Surface electromyograms of agonist and antagonist muscles during force development of maximal isometric exercises—effects of instruction Surface integrated electromyograms (iEMG) of agonist and antagonist muscles were studied during the rising phase of maximal isometric efforts (elbow flexio...

The present study examined the effect of agonist activation and antagonist co-activation on the shape of the knee extension moment–angle relationship in adults and children. Isometric knee extension maximum voluntary contractions (MVCs) were performed at every 5° of knee flexion between 55° and ...
Incomplete activation in the supine position has been proposed as the reason for this discrepancy, but differences in antagonistic co-activation could also be responsible due to altered hamstrings length. We examined the role of agonist and antagonist muscles in explaining the isometric knee extension ...
Commonality and cross talk between recordings were also examined. Results. Cross talk between recordings was deemed negligible despite significant levels of commonality between the agonist and antagonist SEMG, which was attributed to common drive. SEMG RMS amplitude increased significantly for all muscles ...
The onset of the ANTslw was delayed with increasing movement distance. Our results indicate that movement distance is controlled, at the motoneuron pool level, by the interval of a set of pulses sent to the agonist and antagonist muscles in association with pulse amplitude modulation to the ...

Electromyographic activity increased significantly between ∼30% and 40% in both triceps and biceps with vibrations. It is speculated that a similar increase in muscle activity between agonist and antagonist, in combination with an unequal increase in muscle moment arms about the elbow joint, limit...
the need for research-grade yet clinically feasible options, we designed a new load cell device and testing protocol to Quantify Hallux Extension strength (QuHalEx). We aim to describe the device, protocol and initial validation. In benchtop testing, we used eight precision weights to apply ...
2.2. Experimental Setup Participants were seated at a table in front of a handgrip dynamometer (MIE Medical Research Ltd., Leeds, UK) suspended above the table top by a custom-built aluminum frame (Figure 1A). With their right elbow supported by a foam pad, participants gripped the hand...
