Sports talent cannot be equated with an "all or nothing" concept. It is characterized by a dynamic process in which both heredity and environmental development play key roles. The precise balance between these two factors is almost impossible to determine, as it likely varies not only between different sports but also within specific roles in the same sport. The ultimate success of an athlete at the peak of their career is closely linked to the quality of training during the early stages of their development. For decades, experts have been seeking answers to questions about the optimal training process throughout all stages of an athlete's development. One of the most controversial issues in this discussion relates to early specialization, debating whether focused training in a single discipline from an early age is essential for achieving top results, or whether it poses a risk to long-term development and the health of the athlete. The primary goal of this work is to highlight the key characteristics of multilateral development. Special emphasis is placed on the impact of multilateral development on an athlete's career. The ultimate goal includes not only encouraging new scientific research on this topic but also developing strategies that will enable its practical application. The focus is on connecting theoretical knowledge with real-world sports environments to ensure that innovative approaches contribute to improving training processes and the long-term development of athletes.
