Background : Chronic low back pain (LBP) is one of the most frequent causes of disability in women. Aim: The main purpose of the current study was to compare the effects of yoga, TRX, and exercise-related combination programs on pain and lordosis in women with increased lordosis and LBP. Materials and Methods: In this study, 40 women based on the study's criteria were included in the pre-intervention assessments and randomly divided into three experimental groups (yoga, TRX, and exercise-related combination programs) and control group. At this stage, the lordosis angle of participants was measured using a flexible ruler, and their pain was also measured via the Oswestry Disability Index. Furthermore, the experimental groups performed selected exercises for 60 min/session for three sessions/week for six weeks. Results : Our results demonstrated that there was a statistically significant difference between the yoga, TRX, and exercise-related combination programs in lumbar lordosis ( P = 0.003) and pain levels in women with LBP ( P = 0.007). Also, lumbar lordotic angle showed a significant reduction only in the combined groups subsequent to the period ( P = 0.003). Conclusion : In conclusion, the current findings illustrated that exercise-related combination program than other modalities could be used as an exercise-related treatment method to ameliorate lordosis angle and pain in women with LBP.

Background: Functional Movement Screening (FMS) is a tool to determine the individual's potential for the possibility of sports injury. Aim: The purpose of this study was to determine the relationship between functional movement screening scores with flexibility factors, speed and agility in male students in Lorestan province. Materials and Methods: 370 male volunteer students aged 15 to 17 years participated in this study. Spearman correlation coefficient was used to determine the relationship among flexibility, power, speed and agility. Results: The present study showed that there were significant relation between scoring screen for functional movement and flexibility of the left leg, long jumping, high jumping in 15- year- old students. There were significant relations between scoring screen for functional movement and flexibility, flexibility of the right leg, flexibility of the left leg, long jumping, high jumping in 16- year- old students. In addition, in the 17- year- old students, there were significant relation between scoring screen for functional movement and flexibility of left leg, flexibility of the right leg and height jumping. Conclusion: In general, there were significant relation between FMS scores and flexibility and power in three groups of students. The probable cause of this connection can be attributed to in- line lunge tests, Hurdle step, active straight-leg-raise and deep squat, which are directly related to flexibility and power. Therefore, in order to improve the FMS scores of students, it is recommended that students be flexible and able to include in their training program

Purpose: Cell homeostasis is an essential factor in maintaining cellular health and intracellular mechanisms, which can also be associated with inflammatory factors and increased stress for muscle cell health. Calcium is also a necessary factor in cell health and is to establish homeostasis in the body . This study aimed to investigate the effect of high-intensity training on serum calcium levels in combat women. Method: For this purpose, 18 women karateka in the age range of 17 to 23 years were randomly divided into 2 groups: control (n=7) and exercise ((n=11). The exercise group performed proper exercises to improve karate and aerobic techniques for 6 weeks in the intensities of more than 80% of the maximum heart rate reserve.  Physiological indices and blood samples were measured 24 hours before and 48 hours after the training protocol.  To measure calcium cell biomarker, the Pars Azmoon calcium kit was used.  Research data were analysed by covariance test at the significant level (P≤0.05) using SPSS software version 25 . Results: After six weeks of high-intensity training, there was a significant difference in serum calcium levels in the exercise group compared to the control group (P = 0.002).  Also, the results within the group showed a significant increase in serum calcium (P = 0.016) in the exercise group compared to baseline conditions. Conclusions: High intensity training seems to increase serum calcium in female athletes, and this can lead to precursors to cellular disorders, muscle damage and increase inflammatory factors and ultimately decrease the performance of female athletes. However, more research is essential in this regard .

Purpose: The aim of this study was to compare the effects of three methods of endurance, resistance and concurrent training on aerobic fitness and body composition male students with overweight. Methods: Forty five overweight male who were resident of Shahed university dormitory were purposefully selected and randomly assigned into following groups: endurance, resistance and concurrent training. Each Group performed their own protocol for 8 weeks, 3 times per week with specified intensity and duration. Before starting the protocol and 24 hours after the last training session, body composition parameters and aerobic fitness were measured at same condition. Data were analyzed using analysis of covariance. Results: The findings showed that three methods of endurance, resistance and concurrent training protocol had a significant effects on aerobic fitness and body composition parameters. In comparing the difference between groups of three methods of endurance, resistance and concurrent training on aerobic fitness and body composition parameters were significantly different and the variables of aerobic fitness and body composition parameters of concurrent training was more effective than two other exercises. Innovation this research is identical the work out of training (time) in the 3 protocol that to compare intergroup among the most effective way to same time identification. Conclusion: It seems that eight weeks of endurance, strength and concurrent exercise training have effects on aerobic fitness and body composition parameters male students with overweight but all three types of exercise separately with diet modification could be improved aerobic fitness and body composition indices.
