Abstract
The interaction between the nervous and muscular systems, and the enhancement of complex movements that reflect the performance needs in various sports. This research highlights the theoretical frameworks and practical applications in functional training, based on recent scientific evidence published in the last three years. The research focuses on the impact of various functional training patterns, such as exercises based on a specific timing "Every Minute on the Minute" (EMOM), time-based exercises (RFT/FT), exercises aimed at achieving the highest number of rounds (AMRAP), in addition to high-intensity functional training (HIFT), and their effect on specific physiological indicators including: maximum oxygen consumption (VO₂max), blood lactate concentration, respiratory rate response, and heart rate variability (HRV). The research also discusses the implications of applying these training patterns in enhancing fundamental motor skills, such as power output, speed, agility, and balance. The research concludes that functional training achieves measurable improvements in both physiological and skill performance, providing scientific recommendations for its efficient application according to the athlete's experience levels and the needs of their sport.
