Influence of muscle imbalances on the pelvic position in karate trainees

Title: Influence of muscle imbalances on the pelvic position in karate trainees Aim: : The aim of this thesis is to contribute to the solution surrounding the problematic of the position of the pelvis. Also to compare the difference between the positions developed by the influence of muscle imbalances in a group of children aged from 11 - 13 years in sports clubs specializing in karate together with children from 5th - 6th grades in primary schools in the Ústí nad Labem district, children who do sports just for fun and occasionally. Methods: : The main method of this empirical research was that of measuring the somatometric characteristics and the body composition (%BF) in children of middle school age, the method of examination by manual medicinal techniques for discovering the pelvic positions and the lumbar lordosis (Lewit, 2003) and the method of carrying out the diagnosis of the stabilisation function of abdominal muscles according to Kolář (2009) - the diaphragm test, the test of body flexion and the test of intraabdominal pressure. Another applied method was the 3D analysis of the movement for determining the range of the pelvic movement from maximal retroversion up to maximal anteversion. The movement of the pelvis in relation to the laboratory and the lumbar spine in relation to the pelvis..

Enhanced Adhesion of Electrospun Polycaprolactone Nanofibers to Plasma-Modified Polypropylene Fabric

Excellent adhesion of electrospun nanofiber (NF) to textile support is crucial for a broad range of their bioapplications, e.g., wound dressing development. We compared the effect of several low- and atmospheric pressure plasma modifications on the adhesion between two parts of composite—polycaprolactone (PCL) nanofibrous mat (functional part) and polypropylene (PP) spunbond fabric (support). The support fabrics were modified before electrospinning by low-pressure plasma oxygen treatment or amine plasma polymer thin film or treated by atmospheric pressure plasma slit jet (PSJ) in argon or argon/nitrogen. The adhesion was evaluated by tensile test and loop test adapted for thin NF mat measurement and the trends obtained by both tests largely agreed. Although all modifications improved the adhesion significantly (at least twice for PSJ treatments), low-pressure oxygen treatment showed to be the most effective as it strengthened adhesion by a factor of six. The adhesion improvement was ascribed to the synergic effect of high treatment homogeneity with the right ratio of surface functional groups and sufficient wettability. The low-pressure modified fabric also stayed long-term hydrophilic (ten months), even though surfaces usually return to a non-wettable state (hydrophobic recovery). In contrast to XPS, highly surface-sensitive water contact angle measurement proved suitable for monitoring subtle surface changes
