In futsal, fast and explosive movements play an important role in the optimal exercise implementation. Thus, improving the evaluation of anaerobic performance techniques in futsal players is very notable. The aim of the present study was to investigate the correlation between RAST test and Wingate test for evaluation of anaerobic performance indicators in Female Futsal players. A total of 25 women with an average age of 21.72 years and with mean body mass index 21.83kg/m2 and mean percentage of body fat 25.66 percent were selected. For evaluation of the anaerobic performance the RAST test and Wingate test on cycloergometer was used. Then, maximal power, minimal power, average power, fatigue index and heart rate after the end of two tests were calculated. Pearson correlation coefficient was used to determine the relationship between the RAST and Wingate test's indices. Results in a significant level (p<0.05) were tested. According to this study, the average correlation coefficient between maximal power, minimal power and average power of Wingate test and RAST test was observed. There was no significant difference in the fatigue index between two tests. In fact, the RAST test can help sports club coaches to measure anaerobic power in amateur level to select players with optimal anaerobic power in futsal.

Due to the lack of study on the transition effect of the lower body to upper body plyometric training, the aim of this study was to investigate the effect of upper and lower body plyometric training on upper-body electromyography activity in young athletes.

36 male students were selected and divided into three groups: - control; - Upper body plyometric; and - Upper-lower body plyometric (mixed) training. Plyometric exercise protocol (4 weeks/ 3 sessions) included push-up plyometric (4 sets/ 10 repetitions) performed by both groups. The mixed group also continued lower-body plyometric exercise (4 sets/ 10 repetitions on obstacles). At the beginning and end of the course, First, anthropometric tests (fat and fat free mass); and functional (Wingate, overhead medicine ball throwing, and deadlift) was performed simultaneously with electromyography data evaluating.

The physiological work doesn't changed significantly in selected muscles (p>0.05). The median of frequency was significantly reduced in the mixed group compared other groups (p<0.05). In addition, there was no difference in anthropometric, overhead medicine ball throwing, absolute and relative mean anaerobic power between groups (p>0.05). In the deadlift, the mixed group had better significantly records than the upper body group (p<0.05). In the relative anaerobic peak power, there was significant differences between training groups with control (p<0.05).

Based on the findings regarding the confirmed role of lower body plyometric training on the transmission of force into the upper body, it is recommended that athletes use lower body plyometric along with upper body plyometric training.

The aim of this study was to investigate the effect of six weeks of High intensity interval training (HIIT) program and citrulline malate (CM) supplement on nitric oxide levels and exercise performance in elite wrestlers.

In a randomized, placebo-controlled design, 28 elite males’ wrestlers (age, 21.9±2.4 y; height 174.5±3.8 cm) were randomly assigned to CM+training, placebo+training and training, while also all groups participating in 6 weeks of HIIT based on wrestling techniques. Participants completed testing sessions for body composition and aerobic and anaerobic tests before and after 6 weeks of HIIT program. Venous blood samples were obtained before and after 6 weeks.

Nitric Oxide level after six weeks of HIIT and CM supplementation showed significant increase comparing to placebo+training (P=0.001) and training (P=0.035) groups. There is no significant difference between other groups for NO (P> 0.05). There was a significant difference between upper body anaerobic power (peak power, Mean power and fatigue index) of CM group and placebo group (P=0.22), and there was no significant difference between the other groups (P>0.05). Among all body composition data after six week HIIT just FFM of CM+training group showed significant increase comparing placebo and training group (P<0.05).

Daily CM supplementation during six weeks of HIIT training increases serum NO levels and upper body anaerobic power in elite male wrestlers comparing HIIT alone.

The purpose of this study was to investigate the effects of creatine supplementation on some of performance and structural parameters in young wrestlers. For this purpose ninteen young wrestlers with mean weight 67/87±7/935 kg and age 22/75±3/72years were randomly assigned in a double-blind method to either creatine (CT, n=10) or placebo (PL, n=9) treatment group. The CT group ingested 5g of creatine four times a day for five days. The PL. group followed the same supplementation schedule except  they were given glucose as a placebo. Dependent variables included weight, fat free mass (FFM) and performance parameters that contain maximum isometrice strength (MIS) by dynamometer and peak power(PP), mean power(MP) and total work were measured by five 30 seconds arm wingate test with 30 seconds recovery interval between sets. Statistical analyses were done using SPSS/13.5. The effect of exercise protocol was tested using paired t test and independent t tests for comparisons data. Statistical significance was set at p<0.05. Results of the independent "t"-test indicated that the creatine supplementation had no significant change for both CT and PL groups between pre- and post-test in total performance parameters. As well as mean difference body weight and FFM had no significant between CT and PL groups. Whereas body weight in CT group increased abought 0/3 Kg ,it decreased in PL group. This study suggests that short-term creatine supplementation did not significantly change performance and structural parameters during the repeated bouts of maximal exercise in young wrestlers.
