Amir Abbasi Shahin Riyahi Malayeri Seyed Kazem Mousavi SadatiBackground: The purpose of the present study is to investigate the effect of one session of exhaustive activity with supplementation of beta-alanine on the level of carnosine and muscle strength of upper and lower extremities of bodybuilding athletes. Materials and Met MoreBackground: The purpose of the present study is to investigate the effect of one session of exhaustive activity with supplementation of beta-alanine on the level of carnosine and muscle strength of upper and lower extremities of bodybuilding athletes. Materials and Methods: Twenty bodybuilders were randomly divided into two equal groups of 10 who were taking supplemental beta-alanine and placebo. The experimental group consumed beta-alanine for 21 days and the placebo group received dextrose. The level of carnosine and muscle strength of the upper and lower extremities were measured before and after supplementation. Blood sampling was done before and after supplementation after session of exhaustive workout. Paired t-test and ANCOVA were used for data analysis using SPSS 21 software at a significant level (p <0.05). Results: The results of paired t-test showed that in all three variables of lactate, carnosine and growth hormone only in the beta-alanine group, a significant change was observed between pre-test and post-test (P <0.05). And amount of these variables in the post-test showed a significant difference compared to the pre-test. Also, ANCOVA test results indicated that there was a significant difference between the two groups of beta-alanine and placebo in all three variables (P <0.05). Conclusion: Beta-alanine supplementation with an exhaustive exercise session increases the level of carnosine in blood and hence increases the fatigue tolerance of bodybuilding athletes and ultimately improves the muscle strength of the upper and lower extremities of athletes and bodybuilders. Therefore, bodybuilders can use this supplement to improve their performance. Manuscript profile -

According to these findings, the purpose of the present research study is investigating the effect of one session of exhaustive exercise and caffeine consumption on muscle fatigue levels and anaerobic power of the professional female karatekas. Materials and Methods: In this experimental study, 30 professional female karatekas who had at least been present in the Karate national team selected camp once, were chosen based on the entrance criteria and the purposive sampling. The samples were randomly divided into three homogeneous groups consisting of 10 individuals (two groups receiving the 6 and 9 milligrams of caffeine supplement for each kilogram of body weight) and the placebo (6 milligrams of dextrose for each kilogram of body weight). The blood samples were taken prior to and after the anaerobic exhaustive test of Cunningham and Faulkner. The data were analyzed using analysis of covariance (ANCOVA). Results: The results of the study revealed that there was a significant difference between the control and 9-miligram caffeine groups in all variables (P0.005). Finally, the results of the study demonstrated that there was a significant difference resulting from the effect of 6 and 9-milligrams caffeine amounts on the levels of lactate, lactate dehydrogenase, creatine kinase, peak, average, anaerobic power and fatigue of the professional female karatekas (P0.005), though, there was no significant difference among the lactic acid, PH and the anaerobic power drop (P×0.005). Conclusion: According to the results of the study, it is recommended that female karatekas use the 9-miligram dosage caffeine supplement for reducing the levels of muscle fatigue and increasing the anaerobic power and blood PH.

The aim of this study is to compare the effect of selected Pilates, Pilates with Traband and Pilates exercises with both factors such as strength and flexibility of the lower extremities of non-athlete 50-60 years old. Materials and Methods: Thirty participants in this study have been randomly divided into three groups: quasi-experimental, Pilates (10), Pilates Traband (10) and Pilates (10). Before the beginning of the exercises, the strength of the lower limbs and static acceptance and the range of motion of extension and flexion of the thigh have been measured using the test of 30 sitting on a chair, static acceptance and goniometer, respectively. Moreover, all three groups as participated in a course of exercise. These exercises have performed for 8 weeks, 3 sessions per week for 1 hour and have performed after the participants. Data have been analyzed using paired t-test and ANOVA. Results: As result, all three groups show the significant progress due to exercise but there is not any significant variance between the groups, as none of the methods is not better than other training methods. Conclusion: performing Pilates exercises, Weight and Traband based on the availability of training equipment and facilities, is beneficial for the elderly, and this exercise may reduce the negative physical consequences and consequent treatment costs, and helps to slow down the aging process and is effective in improving the daily activities of the elderly.

Materials and Methods: The present study was quasi-experimental with post-test pretest design. The participants of the study were 45 futsal students from the selected high school teams of Tehran cities who were selected according to the inclusion criteria. After homogenization, participants were divided into three groups based on body mass index (15 people in Bosobal training group, 15 people in balance Disc training group and 15 people in control group). After recording the demographic characteristics of the subjects, all subjects were subjected to a static equilibrium (dynamic stroke test) and dynamic equilibrium test (Y balance test). The experimental group received eight-week exercises with Balance pod and bosu ball. However, the subjects in the control group did not have specific training. Finally, all subjects after the end of the training period were tested and the data were analyzed by covariance test at the level of α=0.05. Results: The results of this study showed that eight weeks of bosu ball exercises and balance pod had a positive and significant effect on both the static equilibrium and the dynamic balance of the subjects (P = 0.001). Also, there was no statistically significant difference between the two groups of the bosu ball exercises and balance pod exercises in the static equilibrium (P = 0.505) and dynamic balance (P = .295). Conclusion: According to the results of the study, it is suggested that athletes with functional ankle instability, coaches, therapists and science specialists Rehabilitation use balance pod exercises and bosu ball in order of increase static and dynamic balance.
