Impact of static stretch and muscular contractions on force production within the human triceps surae muscle-tendon complex
… isokinetic dynamometry, electromyography (EMG), sonography and motion analysis were used in three studies on recreationally active human volunteers (n=20). In the first study, three 60-s passive stretches was found to significantly reduce concentric plantarflexor joint moment (5.0%; …

Relationship Between Metabolic By-Products and Nervous System Failure/Fatigue
… relationships between metabolic by-products and EMG characteristics following exercise. The first investigation sought to determine changes in EMG M-wave amplitude of the gastrocnemius following the calf raise exercise. There were no significant changes in M-wave EMG amplitude following exercise. …

The Acute and Chronic Muscle Adaptations Following six weeks of "No Load" and Traditional High Load Resistance Training
… 3.8 (0.6) cm, p<0.001]. For the biceps brachii EMG amplitude, the High load condition was greater than the No Load condition for the last three repetitions (p=0.019). Regarding the triceps brachii EMG amplitude, the No Load condition was significantly greater than the High Load condition for the …

Body dynamics and muscle activity during Chi running
… the gravitational moment about the ankle, and EMG amplitude and duration from four leg muscles. Although no significant differences were found between the two conditions for any of the dependent measures, there was a visible change in running form. A larger number of participants or a different …

Critical analysis of techniques for normalising electromyographic data : from laboratory to clinical research
… of muscle activity derived from surface EMG electrodes are variable due to both intrinsic and extrinsic factors. The intrinsic factors are endogenous in nature (features within the body) and include muscle fiber type, muscle fiber diameter and length, the amount of tissue between muscle …

Reliability of electromyography detection systems for the pelvic floor muscles
… reliability of three different electromyography (EMG) detection systems commonly used to acquire EMG data from the pelvic floor muscles (PFM) at rest, during maximum voluntary contractions (MVCs) and during a coughing task. Twelve nulliparous women between the ages of 24 and 40 participated in the …
