Summary The sport of badminton has attracted a lot of fans due to its attractiveness, movements and hard and high-pressure exercises. For these reasons, it has led experts to consider using new training methods to improve players' performance. One of these training methods is to limit the blood flow known as Katsu exercises. In this training method, the blood flow to the muscle during training is restricted and stopped by closing a flexible rubber cuff or tourniquet around the proximal part of the arm or thigh, which causes blood pools and ischemic conditions. ¬ شد. Therefore, the aim of this study was to compare the effect of four weeks of specialized badminton training with blood flow obstruction on performance and some motor and psychological characteristics in skilled badminton players. For this purpose, in the form of a quasi-experimental design with pre-test and post-test design, elite male and female badminton players of East Azerbaijan province (10 girls and 10 boys with an age range of 15 to 20 years) were selected and completely randomly in One of the two groups of exercises with limited blood flow and exercise without restriction of blood flow and exercise program three sessions per week for four weeks and each session 60 minutes (pressure in the first week 140, second week 180, third week 220 and fourth week 260 ) Did. In the pre-test of all physical fitness factors (agility, dynamic and static balance, height jump, anaerobic power), fatigue through Borg fatigue test, SASI Psych mental fitness questionnaire), Watson and Friend social anxiety questionnaire examined Is placed. The statistical method used is the statistical method of repeated covariance with intergroup factor. Results: The results showed that performing badminton exercises with and without blood flow restriction caused differences in the factors of minimum strength, average strength, agility and dynamic balance between study groups (p <0.05). However, there was no difference between peak power factors, explosive power (high jump) and fatigue between study groups (p <0.05). Also, based on the results of this study, performing badminton exercises with and without calorie restriction caused a difference in the total motivation score of the subjects (p <0.05) but no difference was observed in the level of anxiety (p <0.05). Conclusion: According to the findings of this study, it can be concluded that performing exercises with restricted blood flow compared to the group without restricted blood flow improved motivation and fitness factors specific to badminton. Perhaps the reason for the lack of significant differences between study groups in other factors (anxiety, explosive power and peak power) is due to the level of progress of the athletes participating in this study, which has a high level of performance along with a high ability to Overcome anxiety
