According to recent studies in sports science, the functional condition of boxers accounts for approximately 25% of their overall fitness level, which directly impacts their performance in competition. Weight control (due to weight categories) is one of the key factors in combat sports. The existence of weight categories also determines the specifics of the training process, as athletes in different weight groups have distinct fighting styles. Forced weight loss is often used in the pre-competition period to reach the required weight category. This, in turn, is accompanied by a reduction in the percentage of adipose tissue to critically low levels. As a result, there is a decrease in VO₂max, disruption of functional systems, and a decrease in performance. Maintaining optimal body composition enables the effective utilisation of the body's functional reserves. The aim of this study was to investigate the relationship between the percentage of adipose tissue and the level of functional abilities in combat sports athletes, as well as to determine the optimal range of fat mass that ensures the highest performance. The study involved 52 athletes (boxing – n=37; kickboxing – n=15) aged 18-29, representing different weight categories and having different levels of qualification (Candidate Master of Sports, Master of Sports of Ukraine, Master of Sports of Ukraine of international class, Honored Master of Sports). A total of 121 human examinations were conducted as part of the study. Literature analysis, anthropometric and bioimpedance measurements of body composition (InBody 770, Republic of Korea), ergospirometric tests with Oxycon Mobile, Vyntus CPX, Care Fusion (Germany) gas analyzers, and mathematical statistics methods were used. The study was conducted in compliance with bioethical standards. All study participants signed informed consent forms for data collection and processing. The results confirmed the significant impact of fat mass percentage on VO₂max. The optimal fat mass range is 10±3%, within which maximum functional capacity is observed. This emphasises the importance of maintaining an optimal level of fat tissue in the context of athletic training.
