Abstract
Introduction and aim: Fatigue of injury-prone athletes and their placement in situations such as performing shear maneuvers increases the risk of anterior cruciate ligament injury. Therefore, this research aims to answer the question, does functional fatigue change the effect of neuromuscular training on kinetic variables during cutting in injury-prone male athletes?
Methodology: The current research is semi-experimental and was carried out in two control and experimental groups as a pre-test and post-test design with and without fatigue before and after neuromuscular exercises. 32 males student-athletes aged 18 to 25 with trunk control defects were purposefully selected and randomly placed in the control group (16 people) and the experimental group (16 people). The force plane was used to measure ground reaction forces. Analysis of variance test was used for statistical analysis at a level smaller than P<0.05.
Results: The results of the present study showed a significant improvement in ground reaction force variables in the post-test of the experimental group compared to the pre-test (P<0.05). While none of these variables had significant changes in the control group (P>0.05).
Conclusion: It seems that doing trunk and hip neuromuscular training in athletes with a trunk control defect leads to a significant improvement in the stability of the trunk control, so in the conditions with and without fatigue, they were able to show a significant improvement in the selected parameters of the ground reaction forces. Therefore, this training method can probably be recommended as a beneficial method for athletes and the mentioned conditions

Abstract
Introduction and purpose: The landing error scoring system is a valid and reliable tool for functional assessment of jump-landing movement. The aim of the present study was to investigate the effectiveness of sports training on the landing error scoring system in athletes.
Methodology: Searching between 2014 and 2024 from IranDoc, Magiran, PubMed, Google Scholar, SPORTDiscus, Scopus, PEDro and (ISI) Institute for Scientific Information databases using the combination of jump-landing keywords. Landing mechanics, landing kinetics and kinematics, injury prevention, training, rehabilitation and landing error scoring system were done. A total of 88 articles related to this field were found, after reviewing and screening through the inclusion criteria, 8 articles were reviewed in full text.
Results: Various exercises, including neuromuscular, suspension, knee injury prevention, fatigue and kinesiotype, have been used to be effective on the landing error scoring system test. As a result of corrective exercises and fatigue, the experimental groups showed an improvement and a decrease in the jump-landing movement performance in the landing error scoring system, respectively.
Discussion and conclusion: It seems that in order to prevent jump-landing movement errors and possible injuries caused by it, exercises should be done that, in addition to increasing concentration and coordination in movement, make athletes resistant to factors such as danger.

Abstract
Introdiction and Aim: Nowadays, due to the epidemic of sports supplements, the effects of these
supplements on athletic performance require analysis and evaluation.The aim of the present study was to
investigate the effect of arginine supplementation for one week on oxygen uptake kinetics and time to
exhaustion in female taekwondo athletes.
Method: In this semi-experimental study with pretest – posttest design, eighty female taekwondo athletes
(age: 19.88±2.33 y, height: 167.53±6.04 cm, weight: 60.98±2.4 kg) were randomly assigned to argenine
supplementation (n=9) or placebo (n=9) groups. Subjects performed the incremental test (initially, the work
load 50 watts and 30 watts increase in workload every minutes, as long as subjects will be able to maintain
the highest pedal rate and the failure to reach). To simulate a taekwondo match day test session consisted
of three maximal incremental test intervals (1 to 2 hours). The experimental group was supplemented with
6g arginine powder and placebo group received 6g microcrystalline cellulose each day for one week.
Seven days after, post test accordingly pretest was used by all subjects. Pulmonary gas exchange was
measured by gas analyzer to breath-by breath method. Oxygen uptake kinetics variables (oxygen deficit,
time constant 1, time constant 2) were evaluated by gas analyzer with breath-by breath method. Data was
analyzed using two ways ANOVA.
Results: The time to exhaustion was extended following consumption of arginine (p<0.05). Also the
findings showed that arginine supplementation resulted in a speeding of the oxygen uptake kinetic (oxygen
deficit, time constant 1, time constant 2) (p<0.05).
Conclusion: It seems that arginine supplementation improves oxygen kinetics factors and time to
exhaustion in female taekwondo athletes.

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
Background and Objective: The movement patterns play a key role in the incidence of non-contact ACL injuries. This study attempts to investigate the effect of the +11 program on the jump-landing pattern in female amateur soccer players. Methods: 30 female amateur soccer players were randomly divided into experimental and control groups (15 people in each group). The experimental group performed the +11 program 3 times per week for 16 weeks whereas the control group maintained their regular warm-up method during the study. The jump-landing pattern of the players was investigated by a Special football jump-landing task using the landing error scoring system. Results: The results of the study showed that the 16 weeks of implementation of the +11 program significantly improved the jump-landing error scores of the players in the experimental group. Also, comparison of the results between experimental and control groups showed that there is a significant difference between the two groups. Conclusion: It can be concluded that the +11 program could improve the jump-landing pattern of the female soccer players in pre_ participation evaluation (PPE). Therefore, trainers are advised to use this program as an alternative to regular warm-ups in order to prevent injury.

Abstract
Upper-crossed syndrome is one of the most common disorders of the upper body, which is associated with 45-65% of shoulder pain. This study has been conducted to investigate the effect of corrective exercises focused on chain reactions, on scapular position, proprioception and shoulder functional stability of female students with UCS. 30 female students between 14 and 18 years of age in Urmia city who had the mentioned disorder were selected using the purposive sampling method and were randomly divided into two experimental groups (15 people) and control (15 people). A tape measure was used to evaluate the distance between the median of the sternum to the coracoid ridge and the posterior-lateral distance of the acromion to the thoracic vertebra (scapular position), the Layton flexometer to measure proprioception, the Y Balance Test to evaluate the function of the upper limb, and the goniometer, tape measure and flexible ruler, respectively were used to measure head and shoulder forward angle and kyphosis. Independent and dependent t-tests were used to compare inter-group and intra-group means, respectively. The present study showed that the effect of corrective exercises on scapular position, proprioception and shoulder functional stability of female students with UCS was significant.
