Abstract :
Today, the use of dietary supplements by athletes to perform better athletic skills has earned a special reputation through acceleration of losing weight and fat loss. Therefore, the aim of this study was to investigate the effects of Keratin on body composition swimmers. In this study, 20 male swimmers in aged between 20 to 30 years were selected as subjects. The participants had been explained about what they should be doing and consent was signed by them. Then, the factors of height, weight and body composition were measured. Subjects were matched regarding their age, weight and height then they were randomly assigned to the experimental group including 10 subjects and a control group including 10 subjects. The experimental group and the control group were trained during of 8 weeks (3 sessions per week, meeting one hour). The Creatine group was consumption 20 grams of Creatine in four servings of 5 grams in grape juice where in the first serving was in the morning, the second serving was before a workout at 14:15 (45 minutes before the workout), the third serving was at a few time after the exercise about 16:30 and the fourth serving was before sleeping, but the days when they had no practice, they were taking only in the morning. The placebo group, consumed four servings of 4 grams (2 grams of rice flour and 2 grams of starch) dissolved in apple juice at the same time as in the Creatine group. Body fat percentage of both groups was measured by using calipers and measured three-point method and then training protocol was carried out and all the practice sessions was done to repeat this protocol. Then after 8-weeks swimming training, percentage of body fat were measured and recorded again. After analyzing data using independent t-test and t-test results showed that the group that had consumed Creatine was significant decrease in body fat percentage in the post-test compared with pre-test and so between the two groups, group taking Creatine were significant decrease in percent body fat compared with exercise training.
