The aim of the study, study of Changes in adiponectin, leptin, and plasma lipid profile of Inactive men the  result 24 session, playing futsal. In this study, 20 healthy men 20 to 30 years old, the experimental group (age: 23/5±2/58, weight: 69/36±14/48, body composition: 22/82±4/41) of controls (age: 24/6±2, weight: 68/22±12/71, body composition: 21/99±3/58) inactive randomly divided into control and experimental groups. Experimental groups in each session, indoor futsal training program for eight weeks and will run three sessions per week, while the control group had normal activity. Before the training program, and 48 h after the last session of play, 5 ml blood samples for measurement of adiponectin, leptin, and plasma lipid profile, blood was collected from the participants. After 48 hours of the last training session before the test was re-sampled in the same conditions. T-test results showed that exercise increased adiponectin and high-density lipoprotein and decreased leptin, low density lipoprotein, lipoprotein (a), triglycerides and cholesterol are, however, differences in adiponectin was not significant (P≤0.05). Overall, this study can be taken that these exercises in a short period of eight weeks futsal, adiponectin does not cause significant changes but the significant changes in leptin, high-density lipoprotein, low density lipoprotein, lipoprotein (a), triglycerides and cholesterol in the blood plasma.

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.
