Background: The purpose of present study was to determine comparison the effects of 4 weeks’ badminton specific training with and without blood flow restriction on NO, VEGF and HIF-1 in elite badminton athletes.Methods: for this purpose, 16 boys and girls badminton players with an average age of 16/58±1/72 height, 158±5/52 cm body mass index of 23/08±2/03 kg/m2 as a purposeful sample as a ststistical sample and selected vo2max basis and anaerobic power with purposeful allocation were divided into two groups: specialized badminton training with limited blood fiow and specialized badminton training without limited blood fiow were divided. Both groups performed specialized badminton exercises for one month, three sessions per week and each (90) minute session with an intensity of 14-17 RPE. Cuff pressure for the thighs during the exercise phase was between 160 and 220 mm Hg. Blood samples were taken to measure NO, VEGF and HIF-1α in the basic state and 48 hours after the last training session. 2 hours after eating, Rast test was performed to measure anaerobic power. Shapiro-Wilk test was used to determine the normality of group data distribution and independent t-test was used to determine the difference between groups and dependent t-test was used within the group (P<0/05).Results: The results of the present study showed that four weeks of specialized badminton training in both BFR and NBFR groups in professional badminton players led to a significant increase in NO, VEGF and HIF-1α indices and also no significant difference. It becomes anaerobic. Also, BFR training method is significant on the increase of NO, VEGF and HIF-1α indices compared to NBFR (p <0.05), while there is no difference significant between BFR and NBFR in changes in anaerobic power values (p <0.05).Conclusion: Based on this, it can be concluded that training with BFR is probably a good way to achieve more efficient training adaptations, especially adaptations of blood markers related to the cardiovascular system.
