The paper focuses on the evaluation of physical and mechanical features of ageing glass fibers chopped strands reinforced polymeric composite, denoted MAT300. First, the samples were analyzed with chroma meter in order to determine the coefficients of color change. Then, the control samples were subjected to three points bending since the other samples were exposed to ultraviolet radiation UV-A radiation for 216 hours. After ageing, the color parameters were measured and the bending test was performed in the laboratory of the Department of Mechanical Engineering at the Transylvania University of Braşov, on the LS100 Lloyd's Instruments type test machine. Results showed the characteristic curves of the fibers glass chopped strands MAT samples, the values of the modulus of longitudinal elasticity, the strain and the breaking stress. Also, the color parameters (lightness, greenness and yellowness scale) were measured, both before and after test, in the rupture zone, considering that the sample break is accompanied by the delamination of the fiber and matrix layers.
Sports training is a long-lasting complex process, organized according to the level of performance and the proposed competitive objective. The study aims at highlighting the planning aspects of the sports training in the preparation of ice hockey players. Training planning is organized according to the team's performance level and the targeted result, thus, it can be classified as follows: stage one, anatomical adaptation, stage two, pre-competition stage, competition stage and the transitional stage. The content of each stage is structured and distributed based on the type of effort specific to the hockey game and the main parameters of effort (volume, intensity, complexity). The research methods used for the elaboration of the study are: the study of specialized literature and the pedagogical observation. Sports training is a pedagogical process, which implies compliance with basic principles that ensure the achievement of the established sporting performance, when the methods and means of training are well chosen, adapted and individualised according to the player's bio-mental-physical abilities and his background on the position in the team.In conclusion, in the course of the sports training process, the physical, physiological, mental and intellectual potential of the sportsman will be improved, through planning and periodization elements, which ensure the achievement of high-level sports performance.
In sport, the technical-tactical component is part of the training process of athletes and has a different degree of involvement, depending on the sports branch in question. Ice hockey is a game in which technical-tactical training strategies are decisive in achieving the proposed performance goal. The effectiveness of the implementation of technical-tactical strategies depends mainly on the level of physical training of the team, as this ensures the necessary energy support for the use of tactical elements with higher efficiency indices.During the study conducted by us, we intend to highlight, for the Romanian national ice hockey team - senior level, the incidence of the technical-tactical strategies that we have designed in achieving the performance objective already set - advancing in a superior Group within the World Ice Hockey Championship. The research methods we used were the following: analysis of the literature of specialty, the observation method, the pedagogical experiment method and the statistical method. The independent variable that we have used consists in the implementation of technical-tactical strategies to Romania's national ice hockey team. The results of the research showed the weight of training components during a competitive year. In the pedagogical experiment that we have conducted, the technical-tactical training has an important place in the training process, the individual and collective technical-tactical training weighing the most.After the final evaluation the technical-tactical training strategies were proven effective and led, along with other components of the training, to the achievement of the targeted objective.
