In order to compare the acute effects of OR and Megabasic (two energy drinks)
by a placebo, 24 volunteer male athletes (age: 24.3±2.03 yrs, height
173.56±7.02cm and weight 75.43±3.07kg) participated in two consecutive
RAST tests by 40 min rest interval in between within 3 randomly divided groups.
There were six times blood sampling (before and also 2 and 4 min after than
both tests) in order to analyze blood lactate and PH levels (Gas analyzer) and
also the anaerobic indices (Peak, mean and mean power) was calculated. The
data corresponding to each group’s blood factors was compared by ANOVA for
repeated measurements (post hoc: Bonferoni), their changes between two
consecutive RAST tests was compared by ANOVA (post hoc: LSD) and
anaerobic power data for each group was compared using pair sample t test at
0.05 significance level. Results: Significant changes were observed in blood
lactate and PH levels during repeated measurements in both RAST tests at all
groups (p<0.05). There were also significant differences in the amount of the
changes in between the measurements between groups (p<0.05). Additionally,
Peak and min power only significantly increased in second RAST test rather
than first one and mean power also significantly decreased in both energy drink
groups between the first and second RAST tests (p<0.05). Conclusions:
Consumption of the OR can affect anaerobic power during short term repeated
interval activities. However, there are evident differences in between multiple
brands of energy drinks with regard to the amount of the modifications in the
changes at both blood lactate and PH levels, in spite of this fact that there is
any consensus in this field because of the lack of comprehensive researches.

The aim of this study was designing a specific upper body anaerobic power test for wrestlers and determining validity, reliability and objectivity of the designed test. In order to assess the anaerobic power of wrestlers on the basis of upper body Wingate test, Twenty two wrestlers (age=23/40±3/20 year, height=173/13±6/97 cm, weight=74/55±3/88 kg) of Tehran wrestling team (most of them were Asian champion) were participated in this study. Mean, maximum and minimum of anaerobic power and fatigue indices assessed by both tests. In order to analysis the correlation between power indices and physiological indices (blood lactate and heart rate), Pearson correlation has been used, and the differences between blood lactate after 2 min in both tests assessed. The result indicated that there was significant correlation between maximum (p=0/001 r=0/739), mean (p=0/001 r=0/670) and minimum (p=0/01 r=0/650) of power and fatigue indices (p=0/003 r=0/610) obtained by designed test and Wingate test. The result showed that there was significant correlation between heart rate immediately after doing both tests (p=0/001, r=0/705) and also the result show that there was not significant correlation between blood lactate after 2 min. of doing both tests (p=0/07 r=0/353). Statistical analyses also showed no difference between the blood lactate after 2 min of doing both tests. Analyzing the validity of designed test, revealed that there was significant correlation between max (p=0/000 r=0/840), mean (p=0/000 r=0/861) and minimum (p=0/000 r=0/830) power and fatigue indices (p=0/000 r=772) after performing twice of designed test. In analysis objectively of the designed test, the result revealed that there was significant correlation between max (p=0/000 r=0/832), mean (p=0/000 r=0/858) and minimum (p=0/000 r=0/805) power and fatigue indices (p=0/000 r=0/832) which was done by two different tester. It can be concluded that in respect to Wingate upper body test, the designed test in this study is valid and reliable test to measure the anaerobic power of wrestlers.

One of the most important success factors in most athletic competitions, receiving aerobic power (speed,
agility and jumping) high. Basketball is a great combination of short and long term activities that depend on
aerobic fitness. Anaerobic fitness of many players during the match determines tactical the performance.
The purpose of the present study to investigate the effects of strength exercises on anaerobic power and
some the variables related Traband it. The subjects consisted of 30 basketball players Young, randomly into
two equal groups of 15 subjects (experimental and control) were randomly assigned to 6 weeks and 3
sessions the Exercises were done in a week. To analyze the data, independent samples T-test and paired
sample T-test used at a significance level p ≤ 0/05. Later for six weeks of exercises, significant differences
between the records obtained from the anaerobic power the variables (speed, agility, vertical jump) were
observed between the two groups. The present study showed that the strength exercises with the variables
Traband improve anaerobic power in young basketball players and And according to the results of seem to
exercises Traband useful method for improving performance of the anaerobic the athletes.

The aim of present study was comparison of advanced physical fitness profile between Olympic soccer team members of Iran according to playing position. 29 Invited soccer players to the 17th national Olympic soccer team of Iran dispatched to 17th Asian Olympics Games, Incheon 2014 )mean age of 20.39± 2.01 yrs(, divided into five group of goalkeepers, defenders, midfield players, wingers and attackers according to playing position participated in the study. Body composition parameters (including body mass index, body fat percentage), isokinetic force (peak torque, agonist/antagonist ratio, work fatigue, total work of extension and flexion), aerobic power by analysis of respiratory gases and anaerobic power and fatigue index by Wingate test were packaged for data collection. Descriptive statistics (i.e., mean ± standard deviation) and inferential statistics (i.e., one way ANOVA with Hopkins post hoc after subtracting data  of pre- post) used for analysis data. While it was unbelievable the findings did not show any significant difference between five groups of present study. It seems that Olympic soccer team players of Iran has not prepared in a conditioning principle and based on playing position for participate in 17th Asian games. Moreover it supposed that national players spent most of the preparation periods & specific based conditioning workouts on their clubs, hence due to the short time of conditioning in the national camps trainings, players have not dispatched to the games with favorable preparation.

The purpos of this study was to determine the effect of  twelve session of high intensity cycle training with blood flow restriction on aerobic and anaerobic performance of active student men. To this purpose, 24 valentear active students men from physical eduction faculty of kharazmi university aged 19-23 years old, students (mean ± SD weight: 67.89±6 kg, height: 173.92±5.41cm, and  BMI: 22.7±6.84kg/m2) divided into three groups of blood flow restriction (BFR) (n=8), none blood flow restriction(NBFR) (n=8) and control group (n=8). The exercise consisted of cycling at 80% Wmax for ten 1-min bouts, with a 2-min rest between bouts with 50% Wmax (total time, 30 min). Before and after implementation of the training protocol, Astrand Test to check the aerobic  performance and Wingate test to check anaerobic performance was conducted. To data analysis, the independent t-test, analysis of variance test and post hoc test (LSD) was used. Results indicated that two weeks of high intensity cycling with and without blood flow restriction does have a significant impact on VO2max(p=0.000) and Wmax(p=0.000) and time to exhaustion (p=0.001). The results indicate a further increase in aerobic performance components, in exercise with blood flow restriction training group compared to the unrestricted blood flow training group. The results olso indicated that tow weeks of cycle training with occlusion does not have a significant impact on peak anaerobic power(p=0.064), average anaerobic power(p=0.058) and minimum anaerobic power(p=0.826). In general, the results showed a partial restriction of blood during cycling interval training have affect on aerobic adaptations, but  does not affect on anaerobic adaptations.
