Background: Research on the application of technology in sports in Romania is completely lacking, and the existing studies at the international level have mainly been carried out in recent years. We considered it appropriate to highlight the best practice models of technology application in sports that can be multiplied, adapted, improved, and widely used. The paper aims to identify the use of technology and devices in sports, with an emphasis on their role in training and competitions with the aim of improving sports performance, to provide sports specialists, organizations, and authorities with a wide range of information regarding the connection between sport and technology. The results obtained regarding the application of technology in sports refer mainly to the following: techniques and technologies used in training and competition (portable localization technology and global positioning systems (GPS); Virtual Reality (VR) technology; video analysis; digital technologies integrated into sports training); aspects of sports training targeted through the use of technology (use of technology for athlete health, recovery, and injury management; use of technology for monitoring sports performance and various body indicators); training optimization and ecological dynamics and the sustainable development of sports. Conclusions: Unitary research, at a European or even global level, in a uniform theoretical and practical framework, could lead to much more efficient training with large increases in sports performance. The coaches and specialists working with the athlete determine the specificity of some elements of the training, depending on the characteristics of each athlete. Large clubs could become a factor in generating and disseminating knowledge related to training and competition monitoring, sports performance enhancement, and health, recovery, and injury management. Research directions for the use of technology in sport and the formation of connections with other fields can be extended. For example, combined technologies assisted by specialized software can be used. Creativity must be the starting point for the use and combination of existing technologies in sports and for the creation of new ones. Their creation and use involve the teamwork of athletes, coaches, and specialists from different fields, such as sports, physiology, psychology, biomechanics, informatics, etc.

The paper presents a general description of chains and chain transmissions, their advantages and disadvantages. A triple chain wheel is then projected into the CATIA V5 program. A static analysis of some wheel mounting variants on a camshaft with the Generative Structural Analysis module in the CATIA V5 program is then made. The orientation-fastening variants with a wedge, two feathers or three screws positioned equidistant at 120 degrees on a diameter are analysed. As a result of the finite element analysis, the conclusion is that the three-screw variant is the most appropriate. Material stresses and deformations are smaller, simpler processability, fewer types of components are present overall, maintenance is simpler, and the excentricity of the assembly is lower, with lower vibrations in operation.
