Fatigue responses of human triceps surae muscles during repetitive maximal isometric contractions

Abstract: Nine healthy men (22-45 yr) completed 100 repetitive maximal isometric contractions of the ankle plantar flexor muscles in two knee positions of full extension (K0) and flexion at 90 degrees (K90), positions that varied the contribution of the gastrocnemii. Electromyographic activity was recorded from the medial and lateral gastrocnemii and soleus muscles by using surface electrodes. Plantar flexion torque in K0 was greater and decreased more rapidly than in K90. The electromyographic amplitude decreased over … Show more

“…A técnica da eletromiogra a de superfície tem sido aplicada para sugerir a contribuição de cada músculo na produção do torque de exão plantar, baseada na relação EMG-força 12,16 . A relação EMGforça deve ser aplicada com restrições, mas é bem aceita para contrações isométricas 17 .…”

“…In addition, the different force produced by the GM muscle during knee flexion might also have an influence. It is expected from GM muscle contributed to a higher torque output when the knee was extended at the end of the ECC muscle action 27 . Thus, perhaps an extent of the neural drive to the GM muscle was masked because the analysis of the neuromuscular responses was carried out for the full range of motion and not the final angles of the knee flexion.…”
