The aim of the study was to elucidate the effect of weight training with regulated blood flow in the limbs on changes in active and non-active body mass parameters in mixed martial arts fighters. The research sample consisted of 12 male mixed martial arts fighters aged 18.91 ± 2.35 divided into experimental and control groups. Participants performed 2 weight training sessions without (control group) and with regulated blood flow in the limbs (experimental group) per week for 8 weeks. Body composition was measured by InBody 720 with a focus on skeletal muscle mass, body cell mass, body fat mass and percentage of body fat. Due to weight training with regulated blood flow in the limbs was observed statistically significant increase in skeletal muscle mass (p=0.046, r=0.813) and body cell mass BCM (p=0.046, r=0.813). Contrary to weight training without regulated blood flow in the limbs was observed statistically significant decrease in body fat mass (p=0.115, r=0.644) and percentage of body fat (p=0.116, r=0.642). Weight training with regulated blood flow in the limbs at low load intensity can enhance the level of skeletal muscle mass and body cell mass in mixed martial arts fighters, even without muscle failure. In relation to optimalization of non-active body mass parameters it appears to be insufficient.
