Background and aim: Pain is one of the most common reasons that oblige people to refer to a doctor. With regard to beta-endorphin effect on pain reduction, the aim of this study is investigation of the effect of beta -endorphin serum level on amendment of dysmenorrhea factors after eight weeks aerobic exercise. Materials and Methods: This is a Clinical Trial. The sample included 22 subjects with moderate to severe dysmenorrhea, which randomly divided to two control group (n=10) and exercise group (n=12). Aerobic exercise program included aerobic activity with severity of 60-75% of maximum heart rate for 24 sessions (three sessions per week, each session lasting 45-60 minutes). Serum level of beta-endorphin was measured before and after the exercise intervention. Dependent and independent student t-test was used to investigate the intragroup and intergroup differences of beta-endorphin. Pearson correlation test was used to estimate the relation of variables of study. Results: Findings of study showed that exercise intervention made a significant increasing on the serum level of beta-endorphin. Also there is a significant negative relationship between serum level of beta-endorphin and intensity and perception of pain. But any significant relation with duration of pain was not observed. Conclusion: In general, it seems that increasing of beta-endorphin levels, which was created following the exercise, can have a role in analgesia and reduction of the indicators of dysmenorrhea pain.

Background: Menstrual is an inevitable reality and a part of life for millions of young women around the world. The aim of this study was to evaluate the effects of aerobic exercise on serum level beta - endorphin and pain perception of dysmenorrhea in sedentary adolescent girls.
Materials and Methods: This quasi-experimental study was conducted on 22 subjects with moderate to severe dysmenorrheal and were in age range of 14 to 17 years. They were randomly assigned to a control group (n=10) and experimental (n=12) one. Aerobic exercise program included an aerobic activity with 60-75% of maximum heart rate for 24 sessions (three sessions per week, each session lasting 45-60 min). Before and after the exercise serum level of beta-endorphin was measured. In order to investigate differences within and between groups, Dependent Student t-test and independent student t-test were used.
Results: Our findings showed that exercise intervention significantly increased serum levels of beta - endorphin and decreased pain perception index.
Conclusion: The results indicated that aerobic exercise can cause a euphoric state resulting from a rise in blood concentration of beta -endorphin and improve the perception of the pain of dysmenorrhea.

Background: The aim of this study was to investigate the effect of aerobic exercise in water on cortisol levels and TGF-β in men with multiple sclerosis (MS).
Materials and Methods: This study was a quasi-experimental and applied method with pre and posttest. The study population was 30 male patients with MS referred to a neurologist in Mashhad, Iran; who were randomly divided into two groups (experimental and control). Exercise program for the experimental group consisted of 24 40-minute sessions of aerobic exercise in water for eight weeks, with a frequency of three times per week. So that, based on the principle of overload, after every eight sessions, 10 minutes was added to exercise program. Before and after the exercise program, blood samples were taken from the patients for measurement of cortisol and TGF-β levels. Data were analyzed by independent sample t-test (between-group differences) and paired t-test (within-group differences), and P≤0.05 was statistically considered significant.
Results: The results indicated that there was a significant difference between the two groups in cortisol levels; so that the exercise program significantly decreased cortisol levels (P=0.001). On the other hand, there was no significant difference in TGF-β levels.
Conclusion: The results showed that MS patients can benefit from a longer period of aerobic exercise in water, to improve their own immune system via reduction in TGF-β level.
