  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. تفاصيل المقالة

  در پژوهش حاضر، رابطة فراشناخت با احساس خستگی، به واسطه راهبردهای مقابله‌ای و کمال گرایی مورد بررسی قرار گرفت. این پژوهش در گروه تحقیقات توصیفی و از نوع همبستگی است. به این منظور، 400 نفر از بین دانشجویان کارشناسی دانشگاه تبریز به روش نمونه گیری تصادفی خوشه ای چند مرحله أکثر

  در پژوهش حاضر، رابطة فراشناخت با احساس خستگی، به واسطه راهبردهای مقابله‌ای و کمال گرایی مورد بررسی قرار گرفت. این پژوهش در گروه تحقیقات توصیفی و از نوع همبستگی است. به این منظور، 400 نفر از بین دانشجویان کارشناسی دانشگاه تبریز به روش نمونه گیری تصادفی خوشه ای چند مرحله ای انتخاب شدند. شرکت کنندگان مقیاس تأثیر خستگي (FIS)، فرم کوتاه پرسشنامه فراشناخت ولز (MCQ-30)، پرسشنامة کمال گرایی هیل (PI)، و پرسشنامة راهبردهای مقابله ای (WOCQ) فولکمن و لازاروس را تکمیل کردند. تجزیه و تحلیل داده ها به روش تحلیل مسیر، نشان داد که مسیر علّی غیرمستقیمِ فراشناخت، به‌واسطه کمال گرایی، به طور معنادار بر احساس خستگی اثر دارد (01/0>P). همچنین، کمال گرایی به واسطة راهبرد مقابله ای هیجان محور، بر خستگی اثر غیرمستقیم دارد (01/0>P). بر اساس نتایج این پژوهش، تمرکز بر نقش واسطه ای کمال گرایی در مداخلات درمانیِ افراد مبتلا به سندرم خستگی مزمن، می تواند بخش مهمی از درمان این افراد را تشکیل دهد. تفاصيل المقالة

  Background: The aim of this study was to investigate the effect of one cycle of regular yoga exercises on body posture, fatigue severity, pain and trunk kinematics in girls with erectile dysfunction. Materials and Methods: The present study was an applied study that was performed by quasi-experimental method with pretest-posttest with a control group. The statistical population of this study included all girls aged 25-35 years living in Rasht with erectile dysfunction that 24 people were selected as a sample based on G-Power software based on entry and exit criteria in a targeted and accessible manner. An equal number (12 experimental and 12 control) were divided. The experimental group underwent Iangar yoga for 3 weeks each week for eight weeks, and the control group performed only their daily activities. Then, in order to measure the pre-test and post-test of the head-forward variables, dorsal kyphosis, lumbar lordosis from a flexible ruler, to measure fatigue severity from the MFIS fatigue questionnaire, for back pain from the visual pain intensity scale (vas) and to measure upper rotation Shoulder and shoulder protection by Diota (1990) method and the total shoulder protection on the dominant and non-dominant side was considered as the distance between the two shoulders. Data were analyzed using paired t-test at the significance level of P≥0.05. Results: The results of paired t-test showed a significant effect of eight weeks of yoga exercises on head forward reduction, dorsal kyphosis, lumbar lordosis, fatigue severity, low back pain, upper scapular rotation, scapular protrusion and distance between two scapulae (p≤ 0.001). Conclusion: According to the research findings, it can be concluded that yoga exercises in girls with dorsal kyphosis and cervical and lumbar lordosis in order to strengthen the stabilizing muscles of the spine as well as strengthening the scapular retractor muscles and stretching the anterior chest muscles while reducing the kyphosis angle. Cervical and lumbar lordosis improves the position of the scapula and consequently increases the range of motion of the upper limb. تفاصيل المقالة

  Background and Aim: Chronic back pain is a common problem in the world, which is the most frequent among middle-aged women. The present study was conducted with the aim of investigating the effect of eight weeks of corrective exercises along with water therapy on reducing pain, fatigue, life expectancy and trunk kinematic indices in women with chronic low back pain. Material and Methods: The research sample includes 30 of these people who were randomly selected and then randomly divided into two groups of 15 people, control and experimental. In this study, the amount of back pain was evaluated with the help of a visual pain assessment questionnaire. Also, the quality of life of the subjects was evaluated with the help of the World Health Organization quality of life questionnaire - short form and the intensity of fatigue with the help of the MFIS questionnaire. After evaluating the variables, the subjects were divided into two control and training groups, and the training group did the training program for 8 weeks and 3 sessions per week. The control group also did their daily activities during this period. In this study, the normality of the distributions was investigated using the Shapiro-Wilk test. In order to test the research hypotheses under normal conditions, analysis of covariance (between groups) and correlation t (within groups) were used. Results: The results of this study showed that applying an eight-week corrective exercise program along with water therapy is effective in reducing fatigue and quality of life in addition to reducing pain (P < 0.05). Conclusion: The results of this study showed the effect of corrective exercises along with water therapy on reducing back pain, improving quality of life and trunk kinematics in middle-aged women. Based on this, it seems that applying the exercises of the present study can be effective in improving the quality of life in middle-aged women with back pain تفاصيل المقالة
