Background and Aim: In today's world, physical activity along with balanced nutrition is definitely necessary to improve the quality of life and provide health. The purpose of this research is to investigate the effect of garlic consumption on serum glutathione, lactate dehydrogenase and creatine kinase in inactive people after a residual activity session. Materials and Methods: Ten healthy inactive students with an average age of 25.6±2.6 years and a body mass index of 23.5±1.7 kg/m2 randomly participated in this research. Subjects performed Bruce's training protocol twice with an interval of one week. Then the subjects consumed the supplement or placebo (1000mg capsule containing garlic powder or flour as a placebo) and then performed the residual activity. Independent and dependent t test was used to analyze the data at a significance level of 0.05. Results: Statistical results showed that the level of glutathione decreased significantly in both groups after exercise (P=0.001) and in the garlic supplement consuming group compared to the placebo group (P=0.001). The level of lactate dehydrogenase and creatine kinase increased in both the supplement (P=0.001) and placebo (P=0.001) groups after the residual activity, and there was no significant difference in the supplement user group compared to the placebo group (08 /0=P). Conclusion: The present research showed that acute consumption of garlic, probably by activating the glutathione peroxidase enzyme, increases the absorption of this antioxidant in response to the residual activity. Also, Bruce's residual-building exercise causes cell damage, and taking garlic supplements has no effect on the occurrence of cell damage.

Background and Aim: Today, training on various training surfaces is one of the most important concerns of coaches for improving sports performance, which has rarely been considered in sport teams. The purpose of this study was to investigate the effect of six-week of specific volleyball training on ground surfaces (concrete, floor and sand) on some selected factors of physical fitness in volleyball male players. Materials and Methods: Thirty-six male volleyball players (average age, 16.11±0.82 years) were purposefully selected and randomly divided into three training groups including training on concrete, floor, and sand surfaces. The repeated effort performance test (jump and real-time, time and ideal jump) with four repetitions and rest between repetitions at players’ movement speed between 4 to 8 seconds was used. All tests were performed before and after the training programs. One-way analysis of variance and Tukey’s tests were used at the significance level of p≤0.05. Results: Anaerobic power, explosive power (Jumping record) and time reduction in the repeated performance test significantly increased in the both sand and flooring groups compared to the concrete group. Moreover, agility and dynamic balance in the sand and flooring group had a significant decrease and increase, respectively, as compared to the concrete group. Additionally, dynamic balance showed more increased in the sand group than in the floor group. Conclusion: Specific volleyball exercises on sand compared to other surfaces by increasing training overload caused neuro-muscular adaptations and finally improved sports performance and physical fitness of volleyball players. Accordingly, coaches can use sand surfaces to maximize the benefits of training and prevent injury and pain to players.

Background and Aim: Since saffron has potential properties such as antioxidant and anti-inflammatory effects, it can play a role in modulating inflammatory factors caused by intense sports activities. Therefore, the aim of this research was to investigate the short-term effect of saffron extract consumption on the serum levels of interleukin-6 (IL-6), tumor necrosis factor alpha (TNF-α) and cortisol in young men after an intense exercise session. Materials and Methods: The present research was semi-experimental. Twenty-four male students were randomly divided into two groups (saffron and placebo). Blood sampling was done before and immediately after 30 minutes of vigorous activity with an intensity of 85% of the maximum heart rate stored on the treadmill. After completing the pre-test, the saffron group consumed 400 mg of saffron extract for 15 days, and the placebo group consumed the same amount of starch flour. Then, like the pre-test, two blood samples were taken again before and immediately after intense activity. IL-6 and TNF-α serum levels were determined by ELISA method and cortisol by radioimmunoassay method. Extraction of the results was done using covariance analysis test at a significance level of p≤0.05. Results: After the implementation of the intense aerobic protocol, the concentration of cortisol (p₌0.01) and TNF-α (p₌0.02) in the saffron supplement group was significantly lower than the placebo group; However, there was no statistically significant difference in serum IL-6 levels between the two groups (p<0.49). Conclusion: short-term consumption of saffron before intense activities can moderate the release of some inflammatory indicators and cortisol, and is desirable for athletes involved in intense activities.

Background and Aim: Increased oxidative stress due to exercise as well as the body’s ability to deal with its complications cause different levels of health and disease in people. Therefore, this study aimed to evaluate the effect of two weeks of curcumin supplementation on serum level of malondialdehyde (MDA) and superoxide dismutase (SOD) indices after a session of intense intermittent training in overweight and obese girls. Materials and Methods: Twenty two overweight and obese girls (mean age: 21±1.79 years; weight: 68.80±7.81 kg; body mass index: 31.18±1.96 kg/m2) as purposefully selected and randomly divided into two homogeneous groups (experimental and placebo) according to age and body mass index. The experimental group was underwent intense acute intermittent activity (shuttle run activity protocol; 85 to 95% heart rate percent) and curcumin supplement (80 mg/day post-lunch). The results were extracted using repeated measures ANOVA, one-way ANOVA, and LSD post hoc tests at the level of p<0.05. Results: Intense intermittent activity caused a significant increase in MDA (p=0.001) and a significant decrease in SOD (p=0.001) while two weeks of curcumin supplementation caused a significant decrease in MDA (p=0.009) and a significant increase in SOD (p=0.01). On the other hand, two weeks of curcumin supplementation before intense intermittent activity did not significantly change MDA (p=0.06) and SOD (p=0.21). Conclusion: Two weeks of curcumin supplementation could inhibits lipid peroxidation.

Background and Aim: Caffeine is a widely used physiological stimulant worldwide that athletes use to increase strength and delay fatigue, which is currently available in the form of energy drinks and dietary supplements. Therefore, the present study was conducted to investigate the effect of fatigue and caffeine supplementation on balance and some physical and skill fitness characteristics of young football players in Sarayan city. Materials and Methods: In this way, 24 football players with an age range of 18 to 25 years, at least four to five years of continuous activity were purposefully selected and randomly divided into experimental and control groups. All participants firstly performed the dynamic balance, explosive power (Sargent jump test), agility (Illinois test), and Moore–Christian shooting & passing performance test. Further, the experimental group received caffeine capsules (six mg/kg/day) and the control group received starch capsules (six mg/kg/day). Moreover, the Bangsbo protocol was performed with 42 of two-minute cycles to create simulated fatigue in football players. After the implementation of the fatigue protocol and similar to the pre-test, all the tests were repeated. The results were extracted using independent and dependent t-test at the significant level of p≤0.05. Results: Muscle fatigue significantly decreasing effect on dynamic balance (p=0.001), vertical jump (p=0.001), shooting skill (p=0.001), but no significantly changes were observed on agility (p=0.39) and passing skill (p=0.11), while caffeine had no effect on these changes. Conclusion: Consumption of six mg per kg of body weight caffeine may not have been effective and therefore, it seems that football players can improve their physical fitness characteristics from higher doses of caffeine instead of lower doses to be more effective. Further studies are needed to reach a definitive conclusion.

Background and Aim: Exercising without proper recovery is likely to leave sports-related injuries or cause pain to the athletes. Therefore, the aim of present study was conducted to investigate the effect of six weeks of dedicated football training and various recovery methods on the speed, vertical jump and muscle damage of football players. Materials and Methods: Thirty six young and elite football players of Birjand city were selected purposefully and randomly divided into 4 groups of passive recovery, active recovery, floating in cold water and massage. Subjects first took a 20-meter back and forth running session to the point of exhaustion and then participated in a 20-minute recovery procedure. After that, they practiced football for 6 weeks, and then they did a session of instrument making, and at the end they participated in one of the 20-minute recovery methods. The lactate dehydrogenase (LDH) and creatine kinase (CK) indices were measured by Elisa, velocity by the double-run Bangsbo velocity test, and anaerobic power by the Sargent jump test. The results were extracted using analysis of variance with repeated measures, dependent t-test, and tuky test at the p<0.05 level. Results: Inactive recovery and massage methods following 6 weeks of special football training reduced LDH enzyme (p=0.01 & p=0.04 respectively) and massage recovery method reduced CK enzyme (p=0.001) in participants. On the other hand, cold water recovery improved athletes’ speed (p=0.01), but cold water recovery and massage methods improved vertical jump (p=0.01). Conclusion: The immersion in cold water and active recovery between training sessions accelerates the recovery of physical functions (speed and explosive power) and reduces the indicators of muscle damage (CK & LDH) of football players.

Background and Aim: Low back pain (LBP) is one of the common disorders that causes impairment of daily activities of the Person. Ever various methods have been used in the treatment, but in the case of a comprehensive treatment, researchers generally have not achieved consensus. Hence aim of this study was to compare the effect of two treatment methods Kinesio Taping and sole reflexology on the pain severity and disability of patients with chronic nonspecific low back pain. Materials and Methods: In this semi-experimental experiment 30 male patients with chronic nonspecific low back pain aged 20-40 years were randomly divided into three groups of Kinesio Taping (n=10), sole reflexology (n=10) and control group (n=10). The treatment period lasted 6 weeks and each week consisted of 3 sessions. Place paste Kinesio taping start below the hip bone And then continued the paraspinal muscles And on how to reflexology the spine point on the foot massage was given by massage techniques. In order to assess the pain severity and disability, the VAS and Oswestry Questionnaires were used respectively before and after the treatment. For data analysis, paired t-test and ANOVA was applied at the significance level of P≤0.05. Results: Comparison within and between groups showed an effectiveness of both methods Kinesio taping and foot reflexology on pain and disability (p=0.001). Comparing results of Tukey test Group Kinesio taping significantly better pain relief than the reflexology group showed after intervention (p=0.001) But the amount of disability in people Kinesio taping and reflexology thousand, a difference was observed between the two groups (p= 0.93). Conclusion: Kinesio Taping and sole reflexology can be effective in reducing pain and disability in patients with nonspecific chronic low back pain, but Kinesio Taping greater pain reduction in patients towards sole reflexology.

Background and Aim: The aim of this study was to assess the muscle architectural parameters such as muscle thickness, pennation angle and fascicle length of the biceps, brachii, and triceps brachii (long head) muscles in table tennis players. Materials and Methods: 16 table tennis players and 10 inactive individuals participated in the study, with no significant differences for their age, height, weight, and arm length parameters. Muscle thickness and pennation angle in 50%, 60% and 70% of arm length sites was measured and fascicle length was estimated by B-mode ultrasonography images. Results: The results indicated significantly greater muscle thickness for biceps brachii only in 60% and 70% sites in table tennis players. They also showed significantly greater muscle thickness, lesser pennation angle, and greater fascicle length in all sites of triceps brachii. Conclusion: It seems that muscle architectural parameters developed in table tennis players arm muscles to help them to perform their high speed movements. However, muscle thickness of biceps brachii and triceps brachii at different arm sites showed dissimilar adaptations.
