Abstract
Introduction and Purpose: The swimming start is very important for achieving better results in
competitions. The Purpose of this study was to compare the effects of two plyometric training techniques
both in aquatic and on land in two start techniques (grab and track) of butterfly swimming in Elite male
adolescent Swimmers.Methodology: 20 elite male swimmers divided into two groups of plyometric
exercises in water and land-based. Swimming performance variables including; anaerobic power of hands
and legs, 25 meter swimming record, The time of contact of head with water and the time of keeping
movement in water, Flying distance from the starting point to the end point of contact with water and the
distance of continuing movement after entering the water using both start techniques, the number of
movements of hands and legs in 13 meters butterfly swimming without start and glide. Data analysis was
performed with MANOVA test. Results: Significant difference was seen in the mean time of contact of head
with water in both start techniques (grab and track) of Butterfly swimming; in addition, there is significant
difference in mean number of hand movement and leg movement in butterfly swimming and the number of
hand and leg movement in full 13 meter butterfly swimming after polymeric exercise in two
groups.Discussion and conclusion: According to the findings of this study, using plyometric training
program led to an increase and improvement in the measured parameters, and use these exercises to
improve start swimming recommended

Abstract
The present study aimed to examine the effects of FIFA 11+ comprehensive warm-up program for referees on dynamic balance among male Iranian football referees and assistant referees. Fifty-two football referees and assistant referees who had no previous injury voluntarily participated in the present study. They were randomly assigned into an intervention group and a control one (26 participants each group). The intervention participants took part in a 17-week FIFA 11+ comprehensive warm-up program for referees while the control group performed their usual warm-up trainings during a half season. In order to estimate the dynamic balance of the referees in the pre-test and post-test, Y Balance Test was used. The collected data were analyzed using Descriptive statistics and ANOVA. The results of the present study indicated that the intervention and the control groups were significantly different in terms of dynamic balance in anterior and posteromedial directions and also the referees’ overall balance score before and after the study. However, no significant between them was observed in posteriolateral direction. According to the findings of the present study, it can be concluded that the FIFA 11+ comprehensive warm-up program for referees could improve the referees’ and the assistant referees’ dynamic balance.

Abstract
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.

Abstract
Given that more than 50 percent of patellofemoral pain syndrome include of overuse injuries, the aim of this study was to compare the vastus medialis muscle activity in individuals with patellofemoral pain syndrome after a period of strength and flexibility training with and without the electrophysiological feedback. A total of 30 subjects (15 men and 15 women) participated in this study. Subjects were divided into three group's control, therapeutic and therapeutic with electrophysiological feedback. One-way ANOVA was used to compare the activity of vastus medialis muscle in between groups. The results of this study showed that there was a significant difference between the groups in the activity of the vastus medialis muscle activity (P <0.05). The results of Tukey's post hoc test for intra-group comparisons showed that there was a significant difference between the control group with the therapeutic group (P = 0.024), the control group with the therapeutic group and the electrophysiological feedback (P=0.028) and the therapeutic group with the therapeutic group and the electrophysiological feedback (P<0.001). Conclusion: Regarding the results of this study, therapeutic exercises with electrophysiological feedback have a greater effect on the activity of vastus medialis than the therapeutic group in patients with patellofemoral pain syndrome.

Abstract
As Squat is a popular exercise for support of lower extremity muscles in order to injury prevention this study has been hold to comprise the electromyography of vastus medialis and vastus lateralis muscles in three Squat techniques of man soccer players. 15 soccer players, aged 18-25 years old, who had regular exercise more than two years did open, closed and lung Squats exercise while electromyography of vastus medialis and vastus lateralis muscles were recorded. Data analyzed by using dependent and independent T test and repeated measure ANOVA. There was not significant difference of vastus medialis and vastus lateralis muscles’ electromyography during getting up, going down phases and also for different squat techniques. The vastus lateralis muscle show more activity in all conditions. Though, it is recommended that vastus medialis has bold role for controlling of squat exercise, reduction of Q angle and participants’ knee varus in this study can be the reason of antithesis.
