Sport for persons is promptly and naturally evolving as social phenomenon. This fact is documented worldwide variety of evidence. It is not only about the status and popularity of the Paralympic Games, it is not only dynamically growing number of disabled athletes and the growing range of adaptive sports, sports programs and various levels of competitions, but side by side with it the development of relevant national and international organizations and institutions, and even in some cases linking or merging sports platforms of ablebodied and handicapped athletes. Sport in the context of disabled athletes become parallely extroverted device demonstrations of their athletic abilities and also introverted medium having a positive influence on the biological, psychological and sociological human nature. On the other hand disabled people sport activity involvement is unfortunately very low.

The purpose of the research is to study the possibility of predicting the development of aerobic endurance of athletes through a comparative analysis of the outcomes of genetic and computerized testing. Methods and organization of the research. In our research, we used scientific and methodological literature, as well as the outcomes of competitive activity and genetic analysis of a particular athlete. The total number of survey respondents was 158 people including athletes (n = 85) and coaches (n = 73). Results and discussion. Some authors find the relationship between the ability to develop and manifest endurance and the presence of the appropriate alleles of genes: ACE I, ACNT X, ACNT3 (RX, XX), ADRA2A, AMPDI C, PGC1A Gly, NFATC4, UCP2. Most studies reveal the relationship between the ACE gene and endurance supported by the I allele. Genetic foresight of the possibility of developing aerobic endurance of athletes can become the framework for the application of an individual approach in sport training, and contribute to the development of techniques aimed at the refinement of physical qualities. The modern approach to the coaching and competitive activities of athletes should include both genetic and functional studies of the human body. Conclusion. Sport forecast cannot be based solely on genetic testing results. The presence of polymorphisms in one or more genes associated with sport activity is the platform for good performance in a particular sport, but the actual manifestation of genetic predisposition depends on many factors. These factors include nutrition, daily routine and competent organization of the training process, which requires a high level of theoretical and practical competency of coaches in the field of biomedical education.

The optimization of sport equipment parts requires considerable time and high costs due to the high complexity of the development process. For this reason, we have developed a novel approach to decrease the cost and time for the optimization of the design, which consists of producing a first prototype by 3D printing, applying the forces that normally acts during the sport activity using a test bench, and then measuring the local deformations using 3D digital image correlation (DIC). The design parameters are then modified by topological optimization and then DIC is performed again on the new 3D-printed modified part. The DIC analysis of 3D-printed parts has shown a good agreement with that of the injection-molded ones. The deformation measured with DIC are also well correlated with those provided by finite element method (FEM) analysis, and therefore DIC analysis proves to be a powerful tool to validate FEM models.
