Background: Dysmenorrhea or painful menstruation is considered as the most prevalent problem in women. Therefore, this study aimed to evaluate the effects of eight-week yoga exercises in water on the intensity and duration of pain in female students with primary dysmenorrhea.Methods: In this clinical trial study, we recruited 40 female students aged 18 to 26 years old with primary dysmenorrhea. They were divided into experimental and control groups. Both groups completed the pre- and post-test questionnaires. The experimental group participated in an eight-week yoga exercise plan in water. Shapiro-Wilk test was used for the assessment of the normality of the data. The Wilcoxon test was employed to compare the data. P≤0.05 was considered statistically significant. Also, this clinical trial was registered in the Iranian Registry of Clinical Trials with the code of IRCT20120215009014N245.Results: After eight weeks of yoga practice in water, a significant decrease was observed in the severity of pain (P=0.001), pain duration (P=0.001), and the number of painkillers used in the experimental (P=0.001) group whereas no significant changes were found in the controls.Conclusion: Doing yoga exercises in water can be an appropriate strategy to help reduce the severity and duration of pain and the number of pills used by females with primary dysmenorrhea.

Background: patellofemoral pain syndrome (PFPS) is one of the most common knee injuries, which is caused by the abnormal position of patella. The present study was conducted to compare the effects of an eight-week training in both Total Resistance exercise (TRX) and physioball groups on the amount of pain and motor function of non-athletic women with patellofemoral pain syndrome. Methods: In this semi-experimental study, 30 non-athletic women suffering from patellofemoral pain syndrome were randomly divided into two groups. The first group performed TRX exercises (15 people), and the second group performed physioball exercises (15 people). Both groups received 3 practice sessions per week for a period of 8 weeks. The visual analog scale (VAS), pain scale and Kujala Patellofemoral questionnaire (KPQ) were employed before and after the exercise to assess the pain and motor function. Paired T-test and independent t-test were used. The significance level was considered as P≤0.05. Results: The results revealed that there was no significant difference between functional disability (P=0.14) before and after the exercise protocol (pre- and post-test) in the physioball group. Meanwhile, there was a significant difference in pain (P=0.028). The results for the TRX group indicated that there was a significant difference in pain (P=0.001) and functional disability (P=0.001) between pre- and post-test exercises. Conclusion: The findings of our study revealed that the eight weeks of the strength training program (TRX and physioball) might be beneficial in a conservative treatment plan for reducing the pain intensity and improving the functional disability for subjects with PFPS.

Background: Ankle sprain is one of the most common injuries in taekwondo fighters. This study aimed to investigate the effect of eight-week functional training on soft surfaces on the balance and electromyographic activity of the muscles of female taekwondo fighters. Methods: In this randomized field trial study conducted in Tehran, we selected 16 female taekwondo athletes and assigned them to experimental and control groups. The experimental group performed functional exercises on soft surfaces for eight weeks and three sessions per week. We collected the electromyography activity of muscles by a 16-Channel wireless Electromyography Model V 4.24 (Bayamed Company, Iran) in the biomechanics laboratory of the Allameh Tabataba’i University. Before and after the functional training protocol, we recorded the electrical activity of tibialis anterior, medial and lateral gastrocnemius, rectus femoris, and biceps femoris muscles of stance leg while performing Dollyo Chagi. We analyzed the data using ANCOVA at a significant level of P≤0.05. Results: Eight-week taekwondo training on soft surfaces was significantly effective in reducing the Center of Pressure displacement (P=0.002 and P=0.045) and standard deviation (P=0.023 and P=0.022) concerning internal-external and anteriorposterior directions, respectively. Moreover, we observed an increase in the electromyographic activity of medial gastrocnemius muscle at 100 ms before foot initial contact (P=0.030). Conclusions: The results of this study showed that functional taekwondo training on soft surfaces was able to increase the balance of athletes and augment the feed-forward electrical activity of medial gastrocnemius muscle. Therefore, it seems that these exercises can be used to prevent ankle injuries in these athletes.
