Title: Strategy of postural stabilisation using unstable surface and water barrel. Objectives: The aim of this study is to investigate the level of muscle actiavtion of choosen muscles during lunge on unstable surface or with using water barrel. Investigation of the postural strategy used during lunge orn unstable surface or with the water barrel and creation of methodology for measurment and data analysis. Methods: Into this pilot study, there were picked 5 people (athletes). Data for outcomes where used from 3 athletes. The measurement of level of muscle activation were done by surface electromyography over gluteus medius muscle and musculi multifidii bilaterally.For data procession was used software Origin 2012 Postural stability was measured through force plates by Kistler and gained data were procesed by using software programmes Bioware, MS Excel and Matlab. For data analysis from EMG measurement was used simple comparasion of outcomes. Stabilometry outcomes were analysed by statistical methode t-test. Results: The results indicate greater level of muscle activation during lunge with aquabag than lunge on unstable surface for most of the measured muscles. The only exception, where level of muscle activity was higher, was multifidi muscle on rear leg. Another outcome proved that the postural... |
