1 - The Effect of One Session of the Exhaustive Exercise & Caffeine Consumption on Muscle Fatigue Levels & Anaerobic Power of the Professional Female Karatekas

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.

2 - Comparison of the effect of selected Pilates exercises, Traband training and weight training on strength and flexibility in elderly women

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.

So the purpose of this study was Evaluation of the relationship pattern of (MOPC) and (APFT) tests in measuring aerobic power of military students. Materials and Methods: 25 Officer Students (21-25 years) were purposefully selected. At first, the MOPC (3mile run, MOB, Bench Press, Barfix, Back Squat, Simulated Casualty Evacuation Test) was performed. next stage was to perform the APFT functional test (540 m run, sit-ups, modified barfix, push-ups, sit -reach, 45 m run and agility with 4 x 9-meter test). The test was performed at the 10-day interval as MOPC. Thirdly, after one week of performing the main tests, respiratory gases (VO2, VCO2), RQ, lactate threshold (equivalent to 92% of VO2max), THR, intensity (VO2max%), O2pluse and aerobic power (VO2max) of subjects were assessed by Bruce's progressive and exhaustive test. the assumption of normality was verified using the Kolmogorov-Smirnov test. Also, linear regression analysis was used to examine the relationship between the two performance tests and Statistical analysis was performed at the significant level (p <0.05). Results: : Subjects' VO2max had a relatively weak correlation with MOPC (R = 0.26 and SEE = 0.05) and APFT (R=0.06 and SEE=0.18), which was not statistically significant. A moderate correlation(R=0.49) was observed between the two students' performance tests, however, this proportion was not significant with respect to the coefficient of determination (R2 = 0.28). Conclusion: However, having adequate aerobic power for the military forces indicates optimal levels of cardiopulmonary fitness. But in terms of the level of specialized performance when performing the test, it is not able to evaluate proper motor readiness It is therefore suggested that the components of military performance tests be reviewed and refined. by increasing Ceramide expression.

4 - The Role of Conscious Control Propensity in Determining the Effects of Attentional Foci instructions

Materials and Methods: To determine the children’s conscious control propensity, the Movement Specific Reinvestment Scale was used. Seventy-two children in two high and low conscious control groups that each group divided to three sub-groups (internal, external, and control) entered the acquisition and transfer and retention tests in the basketball accuracy pass task. Results: The results showed that during the acquisition period, low and high conscious control propensity did not have any effect. Though there was a significant interaction between conscious control propensity and attentional foci in transfer and retention tests, but the main effects were not significant. Conclusion: Based on these results, children's motor learning is more effective when the instructions for attentional foci suited their natural tendencies. Manuscript profile
