Abstract
Aim: One of the methods used to improve sports performance is the use of carbohydrate mouth rinse. The purpose of this study is to investigate the effect of carbohydrate mouth rinse on the specific performance of trained soccer players.
Methods: Eighteen professional football players (22 ± 2 years) were randomized into two groups of carbohydrate mouth rinse (CMR) and placebo (P) in a fasted state after eight hours of sleep. During the two main test sessions, players were provided with either a color- and flavor-matched carbohydrate drink or a no-calorie drink (placebo) for a mouth rinse in a double-blind randomized crossover design. Players were asked to rinse the carbohydrate solution in their mouth for 10-15 seconds and then return it to the plastic cup. Sprint performance, maximum height jump, and 30-15 intermittent fitness test (30-15 IFT) were taken from the subjects.
Findings: Carbohydrate mouth rinse increased running distance in 15-30 IFT test. While there was no significant difference between the two groups in the performance of the 30-meter speed test and the maximum vertical jump.
Conclusion: Therefore, those soccer players who are unable to drink carbohydrate solutions due to digestive problems are advised to use the carbohydrate mouth rinse way to improve their performance during the game.

Abstract
Introduction
High-Intensity exercise is accompanied by inflammation and oxidative stress. This study aimed to investigate the effect of the FIFA test with curcumin supplementation on serum MDA, TAC, and CRP in male football assistant referees.
Method
In this semi-experimental study, 20 football assistant referees (mean age 28.56±3.75 years, height 179±4.21 cm, weight 72.78±7.08 kg) were selected voluntarily then were randomly assigned to the curcumin + FIFA test and the FIFA test groups. The test + supplement group, in addition to FIFA tests, received 5 grams of curcumin daily (2.5gram at morning and 2.5 gram at evening) for five days. Blood sampling was performed in three stages (before supplementation, two and a half day before, immediately after, and 48 hours after the FIFA Interval Physical Fitness Test) and serum levels of variables were measured using the spectrophotometric method. Repeated-measures ANOVA and Bonferoni post hoc tests were performed in SPSS26.
Results
There was significant increase in serum CRP, MDA, and TCA in both groups in the first post-test (P=0.000, P=0.041, P=0.008, P=0.009, P= 0.048, P=0.014). Also, in the second post-test of the test group, the increase in CRP and MDA levels remained significant (P = 0.000, P = 0.022). However, TAC became a non-significant increase (P=0.160), while its increase in the test + supplement group was still significant (P=0.013), and in the test + supplement group, MDA became a non-significant increase compared to the pre-test (P=0.186), while in the test group it still had a significant increase (P=0.022). In addition, there was a significant difference between the groups in CRP and TAC values (P=0.024, P=0.05) and a non-significant difference in MDA levels (P=0.129).
Conclusion
Curcumin modulates some of the inflammatory and oxidative stress indices induced by endurance exercise (the FIFA test).

Abstract
The purpose of this study was to compare effect of 4 weeks of strength training in two ways of accommodation and constant resistant methods on maximum strength and power of trained athletes. Sixteen Wushu athletes and wrestlers chosen from Tehran’s clubs with a mean age of 20.50 ±2.00years, height 174.34 ± 6.53cm, weight 70.22 ± 10.50 Kg, and body fat percent, 12.87 ±. 4. 23 participated in this study. After the initial testing of the variables of maximum strength (1RM), upper body power (medicine ball to throw, cm) lower body power (vertical jump, watt) Body fat percent (Skin Fold three point), limb circumference (cm) and Weight (kg), divided in two equal groups. Each group has done resistance strength training program for 4 weeks, three sessions per week, with 85% of their 1RM, with three sets and 5 repetitions with Squat and bench press exercises. But in case of accommodation group, 20% of their 1RM was used by chain through the full range of motion. At the end of the training, re-test of dependent variables were performed under similar conditions. Covariance analysis was used to compare the progressof power and strength between the two groups. This study showed that weight (p=0.391), limb circumferences (P=143), fat (P=0.413), the upper body power (P=0.267), lower body power (P=0.252) and the maximum upper body strength (P=0. 803) there was no significant difference between groups, but in case of maximum strength of lower body (P=0.04) there was significant difference between the two groups. In analyzing the results, although most variables did not show significant difference, but the effects sizeanalyzing of groups showed that in upper body power (ES=0.62), lower body power (ES= 0.64),upper body strength (ES=0.13)and lower body strength (ES=1.84), the results were in favor of accommodation group. This difference in the maximal strength in accommodation group were (62.15% in the upper body, 68.38% lower body) and in constant strength group (86.14% in the upper body, 84.21% in the lower body) respectively. Also the effect size of power for accommodation group were (97.6% upper body, 61.6% lower body) and in constant group (16.4% upper body, 67.4% lower body), respectively. This study showed that in order to increase maximal strength and power, accommodation training method is more effective than traditional constant training.

Abstract
High-intensity interval training (HIT) induces skeletal muscle metabolic and performance adaptations that
resemble traditional endurance training despite a low total exercise volume. On the other hand, fatty acid
oxidation is increases in skeletal muscle with endurance training. This process is regulated in several sites,
including the transport of fatty acids across the plasma membrane. The transportation across this membrane is
recognized to be primarily protein mediated. Therefore, the purpose of this study was to determine the effect of
low-volume high intensity interval training on protein content of sarcolemmal fatty acids transporters (FAT/CD36
and FABPpm) in young men. Twenty recreationally active young men were assigned to a HIT (n=10, 19.3 yr old,
67.2 kg body wt, and 172.7 cm ht) or Control (n=10, 19.7 yr old, 65.9 kg body wt, and 174.4 cm ht) group. HIT
group performed three training sessions per week over 4 weeks. Each session consisted of 8-11×60 s intervals
at ∼100% of peak power output elicited during a ramp VO2peak test separated by 75 s of recovery. Skeletal
muscle (vastus lateralis) biopsy samples were obtained before and after training. HIT increased (17.5%)VO2peak (p<0.05). Also, after 4 weeks low-volume HIT, sarcolemmal content of CD36 and FABPpm increased
14 and 25 percent ,respectively (p<0.05). Therefore, the results showed that the practical model of low-volume
HIT could increase aerobic capacity and sarcolemmal content of CD36 and FABPpm. The increase indicates
that the facilitation of in muscle fatty acid transportation can be adapted which in turn increases the fat oxidation
capacity.

Abstract
The incidence of lower extremity injuries in young soccer players is high, but the risk factors for injuries are unknown. Thus, the aim of this study was to investigate relationship between static lower extremity alignment and injuries in adolescent soccer players. Four teams (78 players) playing at Tehran Asia vision adolescence primer league (14-16 years old) participated in this study. Before entering the season Navicular drop, quadriceps angle, knee hyperextension, genu varum and body mass index was measured. Players were monitored for musculoskeletal injuries through a season (7-month period). overall injury rate was 8.7 injuries/1000 player-hours (95% CI=7.01-10.10). Logistic regression modeling indicated that Navicular drop in preferred foot (OR=4.5; p=0.001), Q angel in preferred leg (OR=2.77; p=0.048), and genu varum (OR=4.06; p=0.021) were all associated with injuries but no association was found in other parameters. Players had an approximately 4.5 times greater chance of suffering a lower extremity injury if they have Navicular drop greater than 1.5 centimeter and approximately 2.77 times greater chance of suffering injury if they have Q angel greater than 15.5 degrees. These findings show that multiple anatomic measures such as Navicular drop, genu varum and Q angle can predict soccer players’ injuries. Results of this study are valuable for coaches and players for injury prevention.

Abstract
Eotaxin, a pro-inflammatory Adipokine is secreted from adipose tissue, which its secretion increases in the obesity and cause neurodegeneration. BDNF is a neurological factor that interferes with cognitive function, fat and sugar metabolism, as well as the pathophysiology of obesity and metabolic syndrome in adulthood. The aim of this study was to investigate the Effect of Six Weeks of Interval Resistance Training on Eotaxin and Brain-Derived Neurotrophic Factor Serum Levels in Overweight young men. Twenty non-active students without regular exercise program from Kharazmi University were randomly selected and divided into two groups of training (n=10) and control (n=10). The training group performed Interval resistance Training for 6 weeks, 3 sessions per week and each session lasted 45 minutes. The training program included 7 moves with intensity of 30-40% of 1RM and velocity 2v for 10 seconds and rest intervals with intensity 30-40% 1RM and velocity v for 20 seconds. Blood samples were taken before and after 6 weeks of training to evaluate the serum Eotaxin and BDNF levels using the Sandwich ELISA. To analyze the data, the covariance test and Bonferron's post hoc test were used to compare the variables. The results of covariance analysis and Bonferroni test showed that 6 weeks of Interval resistance training caused a significant reduction in the weight (p=0.003), body mass index (p=0.004) Waist circumference (p=0.012) and fat percentage (p=0.001). Also, significant increase was observed in muscular endurance (p=0.001), serum BDNF levels in the training group compared to the control group (p=0.024), and serum Eotaxin levels in the training group decreased significantly (p=0.022). Correlation results showed a significant reverse relationship respectively between pre and post training Eotaxin and BDNF (p=0.015 r=-0.511, p=0.013 r=-0.586). Weight loss through six weeks of Interval Resistance training, which accompanied the loss of adipose tissue; resulted in a reduction in serum levels of Eotaxin and increased serum levels of BDNF.

Abstract
All sustained physical activities subject the body to various levels of fatigue. This is especially evident when running, which is one of the most popular forms of exercise and may be described as a reduction in maximum force production and power output . the purpose of this study was to investigate the effect of running in an exerted state on knee muscles power absorption and work during the stance phase of running. Sixteen healthy physical education male students with an average age 22 and SD 2.27 years and height 177 and SD 5.47 cm and mass 72.6 and SD 8.4 kg participated in this study voluntary. Kinetic and kinematic data recorded by using of video camera and force plate. The negative and positive power and work of muscles operating on knee has calculated using inverse dynamic equations in MATLAB2010 Software. Paired sample T test was done to statistical analysis in SPSS 2010 software (p≤0.05). The results of this study indicated that negative peak power and work significantly decreased 33.78% and 22.6% respectively. Although the positive peak power significantly decreased (p≤0.05), positive work didn’t change significantly (p=0.644). The results of this research indicated that the absorbing function of the muscles is decreased following fatigue and may be led to increase the injury risk of running.

Abstract
There is a large necessity for met analytic investigation of the blood pressure (BP) response to aquatic exercise training (AET) in hypertensive patients. was to quantify BP changes after (AET) and identify subgroups exhibiting the largest changes. Clinical trials investigating the impact of AET on hypertensive patients published in English and Persian research journals up to July 2020 were searched from google scholar, Pubmed, Science Direct, SID and magiran. Finally, 12 trials were analyzed to quantify effect sizes (difference in means with 95% confidence intervals) using Random Effects model. Subgroup analyses included gender, menopause status, number of sessions per week and training intensity categories. Simple random-effects meta-regression analysis (methods of moment approach) was performed to investigate the association between changes in BP and changes in both training duration and water temperature. AET decreased both SBP and DBP; -12/29 and -5/69 mm Hg respectively, regardless to hypertensive subjects’ characteristics, training session count per week and water temperature. A tendency for larger reductions in SBP with greater reductions in body weight (β1=0.38, P=0.003) and water temperature (β1=1-.29, P=0.012) were observed after AET. In addition, the magnitude of the effect of AET on both SBP and DBP were significant in all subgroups (except for SBP in males) (P <0.05). AET remarkably lowers both SBP and DBP in hypertensive emphasizing on the clinical importance of AET in controlling hypertension. Likewise; it seems more BP reductions could be inevitable in patients with lower body weight and also elevations in water temperature (up to 38 °C). However, more clinical trials still need to be provided because of the lack of evidence and also heterogeneity of the results.

Abstract
Wrestling is a high contact sport with a significant risk of injuries. Identifying risk factors can help preventing wrestler’s injuries. little is known about the contribution of balance and proprioception to sport injuries. The purpose of this study was to find out the relationship between dynamic balance and knee proprioception and the injuries in young wrestler.72 young wrestlers from Tehran primer league participated in this study. Before the start of season, proprioception was measured at 30°, 60° and 90° knee flexion using the Biodex Isokinetic pro 4 system. Dynamic balance was measured by Biodex balance system. Injuries were recorded by the team's medical staff. Logistic regression modeling indicated that there is no significant relation between Dynamic balance and proprioception of knee at 30 and 60 and at 90 degree and musculoskeletal injuries. Balance and proprioception testing, as performed in the present study, cannot be recommended as a screening test to predict injuries in young male wrestler.

Abstract
The purpose of this study was to compare the prevalence of injuries in the Iranian Football Premier League players before and after the outbreak of Coronavirus (COVID-19) through video analysis in the 2019-2020 season. The types of sports injuries were divided into acute and chronic categories based on the mechanism, and the injuries were analyzed by reviewing 143 videos from 239 matches. Prevalence, time of onset and affected area were recorded in a special sheet. According to the results, 219 injuries occurred before the outbreak of coronavirus and 276 injuries occurred after the outbreak of coronavirus. In the period before and after the outbreak of Corona virus, the lower limbs of the players (58/7%) were damaged more than other parts of their bodies. Also, the highest rate of injury occurred after the outbreak of coronavirus than before in the last minutes of the game (24/3%). Research Findings showed that the prevalence of injuries in Iranian Premier League football players in the post-outbreak period of Coronavirus increased due to home quarantine and closure of matches.

Abstract
Functional Movement Screen Test is one of the tests used to identify asymmetries and limitations in basic and fundamental movements. For time management and fast execution of this test, some researchers have suggested reducing the number of tests. The purpose of the present study was to investigate the internal consistency and correlation between components of this test. The present study was a correlational study. In this study, movement screen test was performed on 165 male and female students aged 18 to 25 years of Shahid Beheshti University using a special FMS kit. Results: The internal consistency of the test, measured by Cronbach's alpha method, was acceptable (α=0.71). The results of multivariate regression test showed that there was a low to medium correlation between the internal components of the test, but a high correlation was observed between the test components and the final FMS score. The results also showed a high correlation between the "four small movements" (Active leg raising, shoulder mobility, stability push up and rotary stability) and the total FMS score and a low correlation between the "three big movements" and the FMS score. Motor function screen test is a valid tool for evaluating motor performance. The results also show that in large communities such as students, and if there is a time limit, "four small movements" can be used instead of seven.

Abstract
The purpose of this research was to investigate the effectiveness of snorkeling on teaching basic swimming skills in non-swimmer children and teenagers with fear of water. This research was an experimental type with a pre-test and post-test design with a control group. The participants were 30 children (8.95±0.64 years old) and 30 teenagers (15.06±0.71 years old) non-swimmers who were afraid of water, and the participants of each group were randomly divided into two experimental and control groups (15 people in each group). After participating in the pre-test of skills of entering the water, opening the eyes in the water, gliding, orientation in the water and movement in the water and breath holding, all four groups entered a 20-session course of swimming training, so that the experimental group with snorkel and the control group without snorkel were taught basic swimming skills by an instructor. Then all four groups participated in the post-test. The data were analyzed by two-factor multivariate analysis of covariance (MANCOVA) and Benferoni's post hoc test. The results of the findings show that the main effects of age were not significant, but the main effects of training and the interactive effects of age and training were significant. Using a snorkel in children and teenagers did not have a significant effect on the skill of entering the water, opening the eyes in the water, but it had a significant and positive effect on the skills of gliding, orientation in the water and movement in the water. Also, the use of snorkel in children and teenagers had a significant and negative effect on breath holding skill. Considering that the results of the present study show the positive effects of using a snorkel on learning the skills of gliding and orientation in water and moving in water and its negative effect on breath holding skill in children and teenagers, it is recommended that the instructors who use snorkel to acclimatize children and teenagers to the water, provide additional training to improve the skill of holding their breath.

Abstract
This study investigates the impact of an anterior cruciate ligament (ACL) injury prevention program on the performance of elite female kabaddi players. Given the debilitating consequences of ACL injuries, the primary aim is to evaluate the effects of an eight-week prevention program on improving the performance of these athletes. This quasi-experimental research was conducted on 27 elite female kabaddi players (aged 18 to 24 years), who were divided into intervention and control groups. The intervention group underwent an eight-week injury prevention training program. The tests included T-test, 20-meter run, Y-balance test, flexibility, hopping, and movement screening. Data analysis was performed using Levene's test and ANCOVA. The results of the ANCOVA indicated that the intervention group scored significantly better than the control group in the Y-balance test for both the right (p=0.002) and left (p=0.001) legs, single-leg hopping (right leg: p=0.004 and left leg: p=0.001), crossover hopping for the right leg (p=0.023), and the sit-and-reach flexibility test (p=0.003). However, no significant differences were observed in the speed, agility, triple hopping, and functional movement screening (FMS) tests. Results: The findings suggest that the eight-week PEP program has a significant impact on dynamic balance for both the right and left legs, hopping (single-leg and crossover hopping for the right leg), and hamstring and lower back flexibility in elite female kabaddi players. However, it did not have a significant effect on left leg hopping, speed, agility, or FMS scores.

Abstract
Introduction and Objective: Ankle injuries are among the most common sports-related injuries, often caused by factors such as "direct contact with a player or the ground, tackles that push the ankle inward or outward, and during jumping and landing." Among these injuries, lateral ankle sprains are one of the most prevalent types, frequently associated with ankle instability. The aim of this study was to compare the effects of balance training and hopping exercises on the proprioception of athletes with functional ankle instability.
Methods: A total of 30 basketball, volleyball, and handball athletes with functional ankle instability, with a mean age of 24.58 ± 3.626 years and a body mass index (BMI) of 25.681 ± 2.126, were randomly assigned to two groups in a clinical trial. The first group (n=15) performed hopping exercises, while the second group (n=15) performed balance training. Proprioception of their ankle joints was assessed at baseline and after six weeks of training. Data analysis was conducted using paired t-tests and ANCOVA via SPSS version 20.
Results: Both balance training and hopping exercises significantly reduced the absolute error in reconstructing dorsiflexion and plantarflexion angles of the ankle (p<0.05). Additionally, the reduction in absolute error for these angles was significantly greater in the hopping group compared to the balance training group (p<0.05).
Conclusion: The findings indicate that both balance training and hopping exercises improve ankle joint proprioception in athletes with functional ankle instability. However, hopping exercises demonstrated greater effectiveness compared to balance training.
