USING PVDF FILMS AS FLEXIBLE PIEZOELECTRIC GENERATORS FOR BIOMECHANICAL ENERGY HARVESTING

The purpose of the study was to extend knowledge about the parametrization of traction spiral stabilization using muscle chains in the educational process. The participants were 26 students aged 19 to 25 years who attended the Technical University in Kosice. After getting information about the aim and content of the research the students participated in pretest and posttest sessions aimed to assess postural parameters (Shoulder Height Left, Shoulder Height Right, Shoulder 2 Shoulder Caliper, Neck Back Height, Neck Front Height) using the full body 3D scanner TC2 NX 16. The experimental factor was an intervention exercise program based on the SM system (SM – stabilization, mobilization = SPS method – Spiralstabilization of the spine). This program took place over 11 weeks during physical education classes. However, the effect of this variable on postural parameters was difficult to determine. Therefore, the individual analysis of collected data seemed to be necessary. Our practical experience has shown that individual approach plays an important role. The correlations between particular pairs of parameters were determined using the Pearson’s correlation coefficient. The results showed a significant correlation between SHL and S2SC (Shoulder Height Left and Shoulder 2 Shoulder Caliper) during the stabilization phase (posttest). The interpreted data and actually increasing number of movement patterns in university students create the need to study the anatomical structures both theoretically and practically. Therefore, it will be necessary to design and administer a compensatory exercise intervention for the population concerned.
