Introduction: Studies have shown that anterior cruciate ligament injury causes long-term periods of disability and long-term effects; Therefore, it is necessary to adopt preventive measures as well as to have studies that determine the effect of injury prevention programs in improving the performance level of players. Therefore, the purpose of this study was to investigate the effect of eight weeks of the anterior cruciate ligament injury prevention program on the function of elite female kabaddi athletes.
Materials and Methods: This research is semi-experimental based on the application of the intervention variable. 27 female kabaddi athletes with an age range of 18-24 years were randomly divided into two intervention and control groups. The intervention group performed prevention injury and enhance performance program exercises for 8 weeks. The tests were taken before and after eight weeks of the PEP program. These evaluations included T-test, 20-meter sprint test, Y-balance test, sitting and reaching flexibility test, hopping test and functional movement screening test. leven's statistical test was used to check the homogeneity of variances and ANCOVA test was used to evaluate and compare the data.
Findings: The results of the covariance analysis test showed that the intervention group had significantly better scores compared to the control group in the Y-balance tests of the right (p=0.002) and left leg (p=0.001), single leg hopping with right leg (p=0.004) and left leg (p=0.000), crossover hopping with right leg (p=0.023) and sit and reach flexibility test (p=0.003) after eight weeks of exercises In addition, in the tests of sprinting (p=0.649), agility (p=0.073), triple hopping with left leg (p=0.784) and right leg (p=0.204), crossover hopping with left leg (p=0.540) and functional movement screening test (p=0.943) did not show any significant difference between the two groups.
Results: The results of this research showed that the eight-week prevention injury and enhance performance program  has a significant effect on the dynamic balance of the right and left legs, hopping (single leg hopping and crossover hopping of the right leg), and the flexibility of the hamstrings and lower back of elite female kabaddi athletes; But hopping (triple hopping and left leg crossover hopping), speed, agility and FMS test scores have no significant effect.

Introduction and aim: One of the serious challenges in sports is injury prediction methods that can help prevent and reduce injuries. Therefore, the purpose of this research was to answer the question, of Do functional movement screen, Y balance, and landing error scoring system tests have the power to predict sports injuries in female student athletes? Methodology: This study was a prospective cohort study. The population of the current research was university female athletes, and the research sample was 124 female student athletes participating in the 15th Iranian Student Sports Olympiad who were evaluated in an available manner. The Y balance test, landing error scoring system, and functional movement screening test were taken from the subjects before the Olympiad, and the injuries of the athletes during the competitions were recorded by the data collection form. In order to statistically analyze the data, the logistic regression test and Pearson correlation coefficient were used. Results: The results of the research showed that a total of 26 injuries were registered during the competition in 124 subjects. None of the predictor variables had the ability to predict the criterion variable (p>0.05). Conclusion: In general conclusion based on the results of this research, it is not possible to predict general injury using functional tests.

Due to the necessity of screening injury the aim of this study was to screen the scores of Functional movement screening tests in active and inactive subject . The study population consisted of University Students aged 18 to 25 years out of which 50 students (25 active and 25 inactive) were selected. Functional Movement Screen by Cook were used for functional screening. After the normality of the overall scores for FMS, Independed-Samples T-Test was used in SPSS (version 16) to analyze the data at significant level of 0/05. According to the findings, overall scores of FMS was significantly different between active and inactive subjects (P=0/001). Cut-off point of 17 was obtained for all subjects. There was no significant difference in shoulder mobility and straight leg raise test scores in the active and inactive people but there was significant difference among the scores of other five tests This prospective study shows that due to the overall score FMS inactive people than in active people are more prone to injury.

Judo is one of the most popular martial arts in the world. Researchers reported a higher risk of injuries during training rather than the time of competition. So, the safe and effective training methods should be considered. As development and application of injury prevention approaches and athletic performance enhancement is necessary, the purpose of this study was to investigate the effect of 8-week Judo Specific Functional Training on the injury risk factors and athletic performance in non-elite male judokas. 46 non-elite judokas participated in this study. Subjects were randomly divided into two groups of experimental (23:N) and control (23:N). For a period of 8 weeks, the experimental group attended a special judo functional training program designed by the researchers. At the same time, the control group participated in the usual judo training program presented by the coaches. The exercises were performed 3 sessions per week and 90 minutes per session. The subjects participated in pre- and post-tests. After data collection, in order to approve data normality and compare the variables, Shapiro-wilk, ANCOVA analysis was implemented at the significant level (p≤0.05) using SPSS version 21. The results showed that scores of functional movement screening (p=0.001), upper extremity Y balance test (p=0.001), vertical jump (p=0.001) and special judo fitness test (p=0.001) significantly increased among the experimental group in comparison to the Control group. This Judo specific functional training program simultaneously modifies or decreases the injury risk factors and improves the athletic performance and has more efficiency and effectiveness rather than the usual judo training program.

Aim: Neuropathy control and management is an objective in therapeutic exercises prescribed for patients with Type 2 diabetic peripheral neuropathy. We examined the effects of 12-week integrated exercises (IE) on glycemic control and peripheral sensation criteria in patients with diabetic neuropathy. Methods: Based on scores of MNSI, we assigned 40 patients into two equal paired random groups (control vs. IE). Pre and post-tests were administered before and after three months of intervention for 3 sessions per week with a time of 60 minutes in the first week and gradually increased with the duration and volume of training to 90 minutes in the final session.
 Results: Repeated measures ANOVA showed no significant interaction between FBS of the groups (P = .26), but significant interactions were observed between the levels of 2 hrs pp G , 4 pm G, HbA1c, Diapason, Monofilament, and Thermofeel in favor of the IE group (P <.05). Conclusion: At the beginning of the IE, we used massage and foam roller to release pain, and improve blood circulation as well as sensation in the neuropathic areas. This may have helped the patients perform the aerobic and resistance exercises more easily Therefore, better glycemic control and peripheral sensation was achieved. Verification of the long-term effects of this training strategy requires further study.
