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
Background: GDNF protein is involved in neurocognitive plasticity and sarcopenia, and the increase of GDNF due to resistance training leads to healthier aging and delays sarcopenia, and TRX resistance training improves the performance and morale of the elderly. The purpose of this research is the effect of six weeks of TRX training on the level of GDNF protein in the serum of elderly women.
Materials and methods: The purpose of the research is applied with a semi-experimental method including pre-test - post-test with control group and field and laboratory data. 28 elderly women aged 55 to 75 years old from the retirement center of Shahid Rajaee Tarbiat University of Tehran were randomly assigned to two experimental groups (15 people) with an average age of 60.86 ± 5.60, weight 75.00 ± 11.95, BMI ± 4.22 27.65 and six weeks of TRX training and the control group (13 people) with an average age of 64.38 ± 4.03, weight 72.69 ± 4.95, BMI 28.33 ± 2.18 and no training were divided. In the first and sixth weeks, both groups were tested for upper body strength, lower body strength and GDNF protein level by ELISA method.Shapiro-Wilk test was used to check the normality of data distribution, Levine's test for homogeneity of variances and one-way analysis of covariance test at a significance level of P < 0.05 was used to test hypotheses and statistical calculations were performed with spss24.
Results: In the results of covariance analysis of upper body and lower body strength, there is a significant difference between the two groups at the level of P <0.05. By removing the effect of the pre-test variable, there is a significant difference between the amount of GDNF protein in the experimental and control groups. By comparing the adjusted averages in the experimental and control groups, the amount of GDNF protein in the experimental group (443.102 ± 15.751) is significantly higher than the control group (209.756 ± 17.029) (P < 0.05).
Conclusion: Six weeks of TRX training had a significant effect on the amount of GDNF protein, upper and lower body strength of elderly women, and it can probably be effective in reducing or delaying sarcopenia.

Abstract
In this study, the effects of vibration training on physical fitness factors in elderly
females investigated. 40 subjects with age 61/09±6/24 yrs, weight 65/84±11/98
kg, height 156/99±5/06 cm and body mass index 26/64±4/23 kg/m2 voluntary
participated in this study and were divided in vibration (n=16), non-vibration
(n=14) and control (n=10) groups. The vibration group performed exercises on
the device (JET VIB) for 10 days with 35-40Hz frequency, 12 mm amplitude and
eight positions. The non-vibration group performed the same exercises (in
position, set and time) on the turned off device. The control group did not
exercise during the study. Leg and hand strength (dynamometer), flexibility (sit
and reach), balance (standing time on one leg) and body composition (skinfold
with caliper) were measured. Paired sample t test and one way ANOVA used
for data analysis. In within group analysis, vibration group showed significant
increase in right (p=0/02) and left hand strength (p=0/01), leg strength
(p=0/008), Flexibility (p=0/005) and left leg balance (p=0/006). In non vibration
group just significant increase in right hand strength (p=0/01). There was no
significant change in control group. Between group analysis showed, significant
increase in right (p=0/006) and left hand strength (p=0/003), leg strength
(p=0/004) and left leg balance (p=0/01) in vibration group comparison with to
other groups. There was no significant change in right leg balance (p=0/),
Flexibility (p=0/005) and body composition in any of groups. Due to the results
short term vibration training can improve flexibility, strength and balance in
elderly subjects.

Abstract
Abstract
The purpose of this study was to investigate the relationship between success
on an over 6000m summit and results of physical fitness tests that normally are
performed by mountaineering federation to select mountaineers for climbing
high mountains. Therefore in this study, relationship between the results of
these tests in 8 female climbers (age, 34.4±8.7year, height, 163.9±5.9cm, body
mass, 60.6±3.8kg) and their performance and success while ascending Mera
Peak (6654m) were assessed. Results showed that none of the cooper test,
long jump, chin up, and sit up tests; and also weekly training volume, age, body
mass, BMI, and percent of body fat were significantly correlated to climbing
ability at altitude, summiting, or incidence of acute mountain sickness.
Summiting was only related to climbing ability over 5000m in 2 days before
summiting (p=0.039) and sleeping history over 3000m (p=0.002). In conclusion,
physical fitness near to sea level could not guaranty climbing ability, summiting,
and healthy mood at high altitude. Climbing and sleeping history at high altitude
may be better criteria for a successful upcoming climb.

Abstract
The aim of present study was comparison of advanced physical fitness profile between Olympic soccer team members of Iran according to playing position. 29 Invited soccer players to the 17th national Olympic soccer team of Iran dispatched to 17th Asian Olympics Games, Incheon 2014 )mean age of 20.39± 2.01 yrs(, divided into five group of goalkeepers, defenders, midfield players, wingers and attackers according to playing position participated in the study. Body composition parameters (including body mass index, body fat percentage), isokinetic force (peak torque, agonist/antagonist ratio, work fatigue, total work of extension and flexion), aerobic power by analysis of respiratory gases and anaerobic power and fatigue index by Wingate test were packaged for data collection. Descriptive statistics (i.e., mean ± standard deviation) and inferential statistics (i.e., one way ANOVA with Hopkins post hoc after subtracting data of pre- post) used for analysis data. While it was unbelievable the findings did not show any significant difference between five groups of present study. It seems that Olympic soccer team players of Iran has not prepared in a conditioning principle and based on playing position for participate in 17th Asian games. Moreover it supposed that national players spent most of the preparation periods & specific based conditioning workouts on their clubs, hence due to the short time of conditioning in the national camps trainings, players have not dispatched to the games with favorable preparation.

Abstract
This study focuses on the design, construction, and validation of a digital-adjustable, weight-free home fitness device for muscle training. The research adopted a mixed-methods approach, providing a comprehensive evaluation of the device's performance. Initially, existing equipment and resistance training methods were analyzed, gathering essential information for the preliminary design. Three-dimensional models and prototypes were developed using software such as Rhino Cross 6 and AutoCAD 2018. For validation, the device’s resistance was tested with a digital dynamometer in eight different settings, yielding a high validity with a correlation coefficient of 0.9. The reliability of the device was also assessed across three exercises (seated leg extension, seated chest press, and seated biceps curl) with 10 kg weights, repeated five times, resulting in a reliability coefficient of 0.8. These results indicate the device's high accuracy and consistent resistance. With precise digital adjustments and the capability for varied strength exercises, this device enables users to conduct effective, high-quality workouts at home, contributing to muscle strengthening and improved fitness.

Abstract
It seems that aerobic exercise in water is more effective in promoting motor fitness factors due to its greater resistance force compared to the dry environment. Accordingly, the aim of this study was to compare the effect of aerobic exercise in water and land on the physical fitness of inactive girls.
Thirty non-athletic girls were randomly divided into two groups water and Land (n=15), and performed aerobic activity for six weeks (3 sessions/week) with 60-70% of maximum heart rate. Before and after aerobic activity, was calculated their explosive power using the vertical jump (Sargent), agility (4×9test), reaction (reaction time test), and the balance (static balance test). For compare pre- and post-test, and to compare post-test results in water and land, One-way ANOVA (p≤0.05).
After aerobic activity (water and land) compared to before, significant improvement was found in the values of explosive power (p=0.001), agility (p=0.001) and static balance (p=0.003), while the comparison of training in water and land did not show a significant difference (p>0.05).
It seems that aerobic activity (water and land) can affect explosive power, agility and static balance, but no effect on reaction, also there is no difference between the two environments.
