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: Upper crossed syndrome (UCS) is believed to be a prevalent deformity among female beauticians. This study designed to investigate the effect of 12 weeks of corrective exercises on the postural angles, namely, forward shoulder, forward head, and kyphosis of female beauticians with UCS.Methods: In this clinical trial study, 40 females were selected through purposive sampling. This study was conducted in Tehran between September 2020 and March 2021. Photogrammetric method was employed to measure forward head and forward shoulder angles. Thoracic kyphosis angle was measured using flexible ruler. The participants were assigned to two groups employing simple randomization. The intervention group carried out corrective exercises for 12 weeks. Paired-sample t-test and analysis of covariance (ANCOVA), at the significance level of p <0.05, were used for data analysis. The clinical trial registration number of this study is IRCT20180626040244N2.Results: The within group comparisons revealed significant changes in all of the postural variables (P=0.001), including forward head, forward shoulder, and thoracic kyphosis of the intervention group. The between group comparisons indicated that a 12-week corrective exercise program significantly decreased forward head (P=0.001) and shoulder (P=0.001), and thoracic kyphosis (P=0.001) angles.Conclusion: The substantial reduction in forward shoulder, forward head, and thoracic kyphosis angles after corrective exercises indicated the effectiveness of these exercises in correcting the postural abnormalities in the beautician females.

Background: Low back pain (LBP) is one of the prevalent injuries among athletes. This study aimed to compare the mechanical energy transfer of gait in female athletes with and without non-specific chronic low back pain. Methods: In this cross-sectional study, based on convenience sampling method, we selected a total of 14 females with NSCLBP and 14 females without a history of LBP who referred to Tehran physiotherapy clinics . To capture marker trajectories and ground reaction forces, we used a Vicon 6 camera motion capture system (Vicon MX, Oxford Metrics, UK), which was synchronized with two ground embedded force plates (Kistler, Winterthur, Switzerland). We performed gait analysis in the biomechanics laboratory of the University of Social Welfare and Rehabilitation Sciences. The independent t-test analyzed the data. All analyses were performed at a confidence level of 95% (p <0.05).Results: The mechanical energy transfer in female athletes with LBP differed from athletes without LBP (P=0.037). There were no significant statistical differences between the ankle and knee joints regarding mechanical energy transfer (P>0.05). Conclusion: Our study showed that female athletes with LBP had higher eccentric mechanical energy compensation coefficient in the hip joint, which is possibly a compensatory mechanism for lumbosacral region disorders.

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.
