Aim: Due to improved Anaerobic performance following creatine or caffeine supplementation and ambiguity and contradiction regarding consecutive effect of creatine and caffeine supplementation, the purpose of this study was to examine the effect of creatine and caffeine consecutive supplementation on lactate and adrenaline, cortisol, insulin like growth factor (IGF-1) hormones response to anaerobic test in young female handball players. Method: 30 club female handball players were randomly assigned to 4 groups: placebo, creatine (Cr group consumed 20 g of creatine, 4 doses 5 g per day for 7 days), caffeine (capsule containing 6 mg/kg Caff) and creatine-caffeine (Cr group consumed 20 g of creatine, 4 doses 5 g per day for 7 days and capsule containing 6 mg/kg Caff). 50 minutes following ingestion of the capsules (Caff/Placebo), 5ml blood sample obtained from brachial vein subjects to measure aforementioned hormones and values recorded as pre-test. Then, subjects performed the RAST protocol. Again, blood samplings were taken immediately following the protocol and as post-test values were recorded. Results: Changes of plasma levels of lactate in creatine group at posttest was higher than the control group (P<0.05), but there was no difference in serum levels of cortisol between intervention groups and serum levels of adrenaline in caffeine group at posttest was higher than the control group. Also, serum levels of IGF-1 in caffeine group was lower than the control group. Moreover, fatigue index and maximum power in caffeine group were higher than the control group and compared to the other groups (P<0.05). Conclusion: Consecutive consumption of creatine and caffeine on lactate and anabolic-catabolic hormones response likely had not ergogenic effect and only lactate response in creatine group and hormonal changes and anaerobic performance in caffeine group were significant.

Aim: The effect of concurrent training on the levels of hormone factors related to appetite and glucose metabolism are unclear. The aim of this study was to evaluate the effect of three months of concurrent training on Nesfatin, Resistin, Visfatin and peptide YY levels in obese women. Method: Twenty-six healthy obese women (age: 24.74 ± 4.38 years, body mass index: 31.50 ± 3.64 kg/m2) were randomly selected to participate in this study; then randomly assigned in two experimental (n=11) and control (n=10) groups. The training program was performed for three months, three sessions (15 to 30 minutes per session) at 60% of maximum heart rate and intensity endurance exercise on a cycle ergometer at 60% of one repetition maximum endurance exercise in resistance exercise at the same time. Plasma nesfatin, resistin, visfatin and PYY levels were assessed before and 48 hours after the training period. Data were analyzed using depended and independent t test at P≤0.05. Results: Nesfatin and PYY levels in the experimental group significantly were higher in post- test compared to control group (P<0.05). Resistin and visfatin levels in the experimental group in post-test significantly lower than control group (P<0.05). Conclusion: Based on the findings, concurrent training increases the levels of resistin and PYY, but decreases the visfatin and nesfatin levels. These training effects may have positive on appetite depressing and insulin resistance; also have prevent the incidence of obesity and diabetes problems.

Aim: Interleukin 13 is a cytokine that can be generated during type 2 immune responses and increased as an inflammatory factor in attention deficit hyperactivity disorder.
The aim of this study was to investigate the effect of 6 weeks high intensity interval training on interleukin 13 levels and insulin resistance in adolescents with attention deficit hyperactivity disorder (ADHD).
Method: In this quasi-experimental research, thirty adolescent boys (mean age: 12.7±5.3 years; body mass index: 25.7±3.2) and thirty adolescent girls (mean age: 12.6±5.4 years; body mass index: 26.3±2.8) with ADHD were randomly allocated to high intensity interval training and control groups. The high intensity interval group performed three HIIT sessions per week for 6 weeks. Each session consisted of four to six repeats of maximal sprint running within a 20-m area with 20-30s recoveries. At the beginning and end of the sixth week interleukin 13 levels and insulin resistance index were assessed. Data were analyzed with ANCOVA with SPSS16 at the significant levels of p<0.05.
Results: Data analysis showed that high intensity interval training decreased significantly anthropometric indices, interleukin 13 and insulin resistance index in experimental group.
Conclusion: The present study revealed that high intensity interval training as an effective method has a positive impact on weight loss, increased level of serum interleukin 13 and insulin resistance index in adolescents with ADHD.

Aim: Clinical studies indicated that types of exercise might have different effects on cardiac health and function. The effect of strength and endurance exercises-induced cardiac release proteins on its health is no clear. Thus, the aim of the present study was to compare the Galectin-3 and NT-ProBNP levels in strength and endurance elite athletes.
Method: Fifteen elite body builders (mean ± SD age of 23.0 ± 1.4 years and BMI: 24.1 ± 1.4 kg/m2) and fifteen elite endurance runners (mean ± SD age of 21.4 ± 3.0 years and BMI: 21.7 ± 2.0 kg/m2) with at least 3 years of tournament playing were participated in this study as the subject. Anthropometric and body composition parameters were measured. Fasting blood sample was taken for galectin-3 and NT-ProBNP measurements. Data were analyzed by Mann-Whitney U test. Data analyses were performed using SPSS software for windows (version 17) and the level of significance in all statistical analyses was set at P≤0.05.
Results: The results indicated that galectin-3 and NT-ProBNP were higher in the strength elite athletes than the endurance elite athletes were (P<0.05).
Conclusion: In conclusion, it seems that type of exercise is effective on blood galectin-3 and NT-ProBNP concentrations.

Aim: The purpose of this study was to determine the effect of ischemic preconditioning (IPC) in different time periods and limbs on lactate and rating the perceived exertion after strenuous exercise in judoists.
Method: In a randomized, crossover study, 13 male judo athletes were volunterd (more than 4 years of judo practice) took part in this study and performed two spacial judo fitness test (SJFT) with 90 second between trials in seven conditions: IPC in hands 5 and 20 min before exercise, IPC in legs 5 and 20 min before exercise, IPC in hands and legs 5 and 20 min before exercise and a sham intervention. IPC treatment consisted of 3, 5 min bouts of ischemia, followed each by 5 min of reperfusion. Rating the perceived exertion immediately after each test and lactate response were measureal after 5, 10 and 15 min of exercise. One-way repeated measures ANOVA and Bonferroni post-hoc test used.
Results: IPC in hands and legs 20 min before exercise decreased lactate accumulation in 10 and 15 min after exercise and rate of perceives exertion than sham condition.
Conclusion: If remote ischemic preconditioning applied in more muscular mass and 20 min before exercise, it improves lactate metabolism and rating of perceived exertion in judo athletes.

Aim: Curcumin is as an anti-inflammatory and antioxidant agent. The aim of this study was to evaluate the effect of curcumin supplementation on muscle damage indices following intensive eccentric exercise.
Method: Ten healthy, nonsmoking, active young men participated in this cross over study. Participants were randomized in a double-blind placebo-controlled fashion in two placebo (P), and curcumin (C) groups. After first blood sampling, subjects did a session of intensive squat exercise. Immediately after exercise, a second blood sampling was collected. Afterward, subjects took 150 mg curcumin or placebo, and sampling was performed 24, 48, and 72h after exercise blood sampling was done again. After a two weeks recovery period and with the change of supplements the test were repeated. Creatine Kinase (CK), and bilirubin were measured as muscle damage markers. Visual Analogue Scale (VAS), Range of Motion of the knee (ROM), and tissue swelling were measured at all time series.
Results: CK significantly decreased in C group 24h after exercise compared with the P group (P<0.05). Bilirubin significantly decreased in C group 72h after exercise compared with the P group (P<0.05). VAS was increased in both in both group exercise, but showed significant decrease in C group compared with P group 48 and 72h after exercise (P<0.05).
Conclusion: It seems 150mg curcumin supplementation after a session of intensive eccentric exercise ameliorate pain and muscle damage through its analgesic, anti-inflammatory, and anti-oxidative properties..
