Introduction: There is empirical evidence that training with bimanual grip can improve tennis’s technical and tactical level. However, this practice lacks a scientific study supporting its fundamentals and methodological arguments for effective training. Objective: Investigate the influences of two-handed grip training on balance and motor coordination in tennis players. Methods: The study was conducted by literature data collection, experimental testing, and mathematical statistics. A bimanual grip training protocol was designed and tested on volunteer athletes. Biomarkers were collected, discussed, and analyzed inter- and intra-group statistically. Results: After 5 weeks of basic training, there were significant differences in homeostatic control and physical agility between the experimental and control groups. After training, the dynamic balance ability of the experimental group athletes was significantly improved. Conclusion: The study results show that training, according to the proposed protocol, can benefit athletes' dynamic balance and motor coordination, improving motor coordination and balance in practical sports movements. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.
