Background and Aims: Nowadays, suspended exercises have been considered as an effective way to improve Core stability in healthy individuals and those with musculoskeletal disorders. However, the activity of different Core muscles while performing suspended exercises has not been investigated yet. Therefore, the purpose of the present study was to compare electromyographic activity of selected Core muscles while performing selected Core stability exercises using TRX. Materials and Methods: A total of 15 healthy physically active female students participated in the current study. Each participant performed three repetitions of each of bridge, plank, and lunge exercises with the feet placed inside the TRX foot straps. Simultaneously, surface electromyographic data was collected on rectus abdominis, external oblique, erector spine lumbalis, and superficial lumbar multifidus. Resulting row data was amplitude normalized and the root mean square was then determined. Repeatedmeasure analysis of variance was used to determine any differences across the three exercises on a test group (p=0. 05). Results: Different levels of muscle activation were observed during the three different exercises. Rectus abdominis activation was the greatest during plank exercise, while superficial lumbar multifidus activity peaked during feet suspended lunge and bridging. Conclusion: Considering the levels of activity of all investigated muscles, plank seems to have the highest and lunge the least impact on improving the stability of Core region.

Background: Women may experience different problems in every aspect of their sexual life throughout their lives,therefore, it is essential to check women's sexual health and try to improve it. The present research aims to assess Core stability trainings on postpartum mothers' sexual desire. Materials and Methods: This quasi-experimental research was conducted by random sampling on 72 mothers who referred to comprehensive health centers in Isfahan in 2019 in postpartum period. The samples were divided into experimental and control groups by random placement method (blocking). Core stability exercises were performed in the experimental group for 24 sessions. The demographic questionnaire and Female Sexual Function Index (FSFI) were filled out in two stages (before and one month after the intervention) by the samples, and the data were analyzed by Mann-Whitney, independent t-test, paired t-test, Chi-square. Results: The result of this study showed that the average sCore of the sexual desire after intervention in the experimental group was significantly higher than that in the control group (p = 0. 03). The average sCore of the sexual desire after the intervention in the experimental group was significantly higher than that before the intervention (p < 0. 001). The average sCores of the sexual desire before and after the intervention in the control group were not significantly different (p = 0. 40). Conclusions: Eight weeks of Core stabilization exercises can improve endurance of the pelvic floor muscles and the central part of the body, subsequently promoting females' sexual desire. The findings of this study can be considered in the fields of education, health, clinical, and policy.
