The aim of this study was to register and compare muscle activation patterns during sitting down in four situations with different positions of the lower and upper limbs. Muscle activity was registered with the use of 8-channel surface polyelectromyography (Noraxon - Myosystem 1400A). We tested the following muscles bilaterally during sitting down (tibialis anterior muscle, medial head of the gastrocnemius muscle, gluteus maximus muscle, erectores spinae muscles). It was registered, that the medial head of the gastrocnemius muscle and/or erectores spinae muscles were activated as the first ones in both groups of the subjects under study in the most of the studied postural situations. We registered differences in timing among different studied body and limb positions. There was revealed a great variability in the sequence of muscle activation depending on upper and lower limbs position."@en . . "ZAATAR, AMR MOHAMED ZAKI" . . "41" .
