Comparing professional futsal practice sessions with and without blood restriction on angiogenesis and angiostatin stimulation in active young men

The aim of this study was comparing professional futsal practice sessions with and without blood flow restriction on angiogenesis and angiostatin stimulation in active young men. Among physical education students, 12 volunteer selected and randomly divided into two groups of exercise with and without blood restriction. All of the subjects did the 3 vs. 3 professional futsal practice in 6 repetition of two minutes. One minute determined as resting time between the repetitions. In exercise group with blood restriction, a cuff on the thighs with pressure of 140 Mm Hg were applied. The blood samples were collected before and after the exercise sessions to determine the ratio and values of VEGF and endostatin concentration. Elisa method was used to measure the variables. To determine within and between group differences, Paired T test and Independent T test were used respectively at significance level of 0.05. The results showed no significant differences for the measured variables between the groups. However, VEGF significantly decreased in the two groups after exercise session (P=0.002). The ratio of VEGF to endostatin significantly increased in exercise with blood flow restriction group (P=0.002), but not in the Exercise group (P=0.006). Interestingly, the endostatin concentration increased significantly after the trial (BFR: P=0.003, NONBFR: P=0.005). Blood lactate was significantly higher in exercise group with blood restriction(P=0.003). In conclusion, a professional futsal practice session can decrease blood level of VEGF and increase its endostatin.
