The research purpose was to assess the body composition parameters of athletes from the Russian Muay Thai national team and determine the relationship with achieving high sports results in the international arena.
Methods and organization of research. The study involved 39 athletes (20 men and 19 women), members of the Russian Muay Thai national team. Testing was conducted using the InBody 770 bioimpedance analyzer (manufacturer InBody Co., Ltd., South Korea) during a training camp in Kislovodsk. The following parameters were assessed: body mass index (BMI), percentage of body fat (PBF), skeletal muscle mass (SMM), basal metabolic rate (BMR), phase angle, and segmental lean mass analysis [4].
Results and discussion. Male national team athletes demonstrated an optimal ratio of muscle and fat mass (PBF 3.7-6.2% among team leaders, SMM >50% of total body weight). The female team showed an average PBF of 14.8-19.5% with minimal asymmetry in lean mass (difference less than 0.1 kg). The obtained morphological indicators correlate with high sports achievements: at the 2025 European Championships, the Russian team won 84 medals (46 gold) and secured 1st place in the team standings [2].
Conclusion. Bioimpedance analysis is an effective tool for monitoring the body composition of combat athletes, enabling optimization of the training process and competition preparation. The optimal morphological profile of the Russian Muay Thai national team athletes is one of the key factors of their success in the international arena [5].
