  Background: The results of some research studies have revealed the positive effect of the caffeine consumption on the muscle fatigue and anaerobic power of the athletes. 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 (P0.005). 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 (P0.005), 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.

  Background: Changes in the human body due to the aging process, especially the loss of strength and flexibility of the lower limbs can increase the risk of falls. 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.

  Background: Muscle damage caused by exercise occurs in all sports activities with eccentric contractions. The aim of the research was the effect of consuming chocolate milk on muscle damage enzymes of men professional football players. Materials and Methods: 22 male soccer players (24.5 ± 1.2 years old) were voluntarily and randomly placed in two experimental and control groups. The training protocol for two weeks, 3 sessions per week and each session for 60-90 minutes included speed/plyometric training (ladder legs, agility training and coordination training) followed by resistance training. Subjects used 672 ml of chocolate milk supplement after training. Blood samples were taken before starting the research protocol and 48 hours after the last training session. Analysis of covariance test was used at a significance level of p<0. 05. Results: Consuming chocolate milk caused a significant decrease in CK, LDH, AST, ALT, ALP and muscle pain in male soccer players (P = 0.001). Conclusion: According to the results, chocolate milk supplement can be used as a factor in reducing muscle damage enzymes in male football players. Manuscript profile
