Reproducibility of electromyographic and mechanical parameters of the triceps surae during submaximal and maximal plantar flexions.

摘要: Introduction Neuromuscular parameters must be reproducible to examine neuromuscular adaptations in interventional and clinical studies. The reproducibility of for the soleus (SOL), lateral gastrocnemius (LG), medial (MG) was assessed over a period 2 weeks. Methods Thirteen subjects (27.4 years, 69.5 kg) were tested numerous electromyographic (e.g., voluntary electrical evoked EMG) mechanical activation level) 3 test sessions. Results majority data (28 34) revealed moderate substantial reproducibility. Hmax20% /Mmax20% Vsup /Msup less LG than MG SOL. Muscle activity M-waves did not differ between muscles. ICC >0.79. Conclusions H-reflex during contraction should considered with caution. Mechanical on muscle level are reproducible. is sufficient
