In sports science, genetic testing has become a valuable tool for understanding the genetic foundations of athletic ability. This study investigates whether genetic testing may be used to customize training plans for French swimmers to optimize performance, reduce injury risk, and improve recovery. Coaches can determine genetic predispositions pertaining to muscle composition, metabolism, injury risk, and recovery capacity by analyzing the genetic profile of an athlete. With the use of this data, individualized training plans that target deficiencies, build on strengths and increase success rates in the pool may be created. The research was based on primary data analysis to determine whether the research used Smart PLS software and generated results, including descriptive statistics, and correlation coefficient analysis, which also explains the smart PLS Algorithm Model between them. Event specialization, dietary optimization, injury avoidance, recovery optimization, talent discovery, and long-term athlete development are some of the main uses of genetic testing. French swimming programs can acquire a competitive advantage and set up their athletes for success on the international scene by incorporating genetic information into coaching procedures. A discussion of the ethical issues surrounding the use of genetic data in sports is included, focusing on the value of informed consent and private rights. The overall research found the positive and significant role of genetic testing in tailoring training programs for French swimmers. Genetic testing has great potential to enhance training regimens and bring forth the hidden talent of French swimmers, solidifying France's standing as a dominant force in the world of competitive swimming.
