Different Types of Sitting Postureand Response of the Axial System
PROMĚNLIVÉ TYPY SEDŮ A ODEZVA AXIÁLNÍHOSYSTÉMU
Na souboru 23 studentů byla pomocí Moire metody, barografického vyšetření a EMG vyšetřenízkoumaná odezva axiálního systému na uměle navozené typy sedů. Byly zvoleny tři druhy sedů(nekorigovaný sed bez použití pomůcek, sed na sedacím klínu a sed na labilní ploše – míč overball).Doba měření pro každý typ sedu byla 2 minuty. Výsledky ukázaly klíčové postavení pánve. Břišnísvaly se nejvíce aktivovaly v poloze na míči. Rozložení tlaku na sedací hrboly se snížilo na sedacímklínu.

Overview
By means of Moire method, barographic examination, and EMG examination the response of axialsystem on artificially evoked types of sitting positions was investigated in the complex of 23 students.There were chosen three types of sitting positions (incorrected sitting position without the use ofaids, sitting position on a sitting wedge, and sitting on an unstable surface – overball). The time ofmeasuring for each type of the sitting position were 2 minutes. Results showed the key position ofpelvis. Abdominal muscles were the most activated in position on the ball. Spread of the pressureson sitting tubercles was lowered on the sitting wedge.
