Abstract
Aim: The purpose of this study was to examine the response of the visfatin to acute endurance exercise pre and post 8-weeks trainingin untrained obese healthy men. Method: Twenty two subjects (age 29.06±3.83 years, weight 90.96±4.68 kg, height 171.3±4.88 cm, and BMI 30.76±1.8 ...

Aim: The purpose of this study was to examine the response of the visfatin to acute endurance exercise pre and post 8-weeks trainingin untrained obese healthy men. Method: Twenty two subjects (age 29.06±3.83 years, weight 90.96±4.68 kg, height 171.3±4.88 cm, and BMI 30.76±1.8 kg/m2) were volunteered to participate in the current study. The subjects were divided randomly into two experimental (n=11) and control (n=11) groups. Experimental group participated in 8-week endurance training program three times per week. Exercise intensity increased from 60 percent of maximum heart rate to 65 to 70 percent after 4thweeks until the end of training program. Acute exercise test (cycle ergometer exercise, 30 min at 60 percent of maximum heart rate) were employed before and after training period. Blood samples were collected before, immediately, and 30 min after acute exercise at before and after endurance training period to measure plasma visfatin variations. Results: The results by two-way Anova with analysis showed before training period, visfation levels changes were not sigificant after acute exercise , immediately and 30 min aftery in both groups. Conclusion: These data indicate that endurance training is associated with decrease in resting plasma visfatin and body fat in obese men. Moreover, one bout of endurance training can decrease the plasma visfatin in response to acute exercise.

Aim: Recently, energy drink consumption by athletes has become increasingly popular. Athletes believe that energy drinks can be used to enhance their performance during training and competition due to their potentially ergogenic ingredients such as carbohydrates, caffeine, sodium and taurine, among others. Therefore, the purpose of this study was to determine the effectiveness of the acute ingestion of a taurine and caffeine-containing drink on Wingate cycle performance and blood lactate levels in active men. Method: A sample of 19 active male students (age: 8/0±3/22years, height7/6±2/71: cm, weight: 4/5±9/175kg) from Mazandaran University were selected. This research was conducted on two separate sessions with four days rest in between. In the first session, all of the subjects participated in the Wingate test, after having a standard breakfast, and after the blood taking (before and 2 min after test) and hand muscle esterangth measurement. In the second session, subjects were randomly divided in three groups (taurine and caffeine-containing drink, placebo and no drink groups). Immediately after having breakfast (forty minutes prior to test beginning), each group received 6 ml/kg.bw of related beverages. Results: In the taurine and caffeine-containing drink group, minimum (p=0/017) and mean (p=0/029) power was increased and blood lactate before (p=0/357) and after (p=0/920) the test, was unchanged Conlusion: In conclusion a commercially-available taurine and caffeine-containing drink (Red Bull) enhances anaerobic power of active male.
