        Introduction: The purpose of this study was to comparison of SSG and sprint on testosterone, cortisol, blood cell count, and physical fitness indices in teenage soccer players. Material & Methods: In this experimental study, thirty-six teenage athletes (13.55±0.53) were randomly divided into control, SSG, and sprint groups. The subjects in the sprint group underwent 45-minutes short bursts of sprinting. The SSG group exercise program 45-minutes consisted of 8×3 minutes with 3 minutes of active recovery between sets was performed on a small Football pitch without a goalkeeper. In contrast, the control group continued their usual routine activities for 4 weeks (3days/week). Basal levels of K-TEST, RSA, and YO-Y0 tests, as well as blood indices of testosterone and cortisol and blood cells, were measured before commencement and after 4 weeks of training. Results: The results indicate that sprint training led to a significant increase in testosterone, T/C ratio, RBC, and WBC compared to the control group and significantly decrease in cortisol and agility performance. SSG also caused a significant increase in testosterone, testosterone to cortisol ratio, RBC, WBC, SII, and aerobic performance, with a significant decrease in cortisol and agility performance. Additionally, in the control group, cortisol showed a significant increase, and the testosterone to cortisol ratio was significantly decreased (p<0.05). Conclusion: The present study revealed that both sprint and SSG training individually can have desirable effects on testosterone, cortisol, T/C ratio, WBC, and RBC and agility test. Sprint and SSG were found to be effective for these factors. The SSG training program increases WBC, SII and aerobic performance. Manuscript profile

        Introduction: The aim of this study was to investigate the effect of simultaneous resistance aerobic training on selected indicators of body composition, maximal oxygen consumption and thyroid hormones in sedentary overweight and obese women with hypothyroidism. Material & Methods: In this semi-experimental study, 24 women with hypothyroidism were randomly divided into two control groups (number = 12 people; body mass index: 31.33±3.62 kg/m2) and experimental (number= 12 people; body mass index: 32.33 ± 4.05 kg/m2) were divided. The experimental group did 8 weeks of simultaneous aerobic-resistance training. Each session consisted of 30 minutes of aerobic training (80-55% of maximum heart rate) and 30 minutes of resistance training. Before and after the 8-week training period, body composition measurements (weight, body mass index, waist-to-hip ratio, and fat percentage), maximum oxygen consumption (Rockport 1609-meter walking test) and blood hormone measurements (TSH and T4) to It was done. Statistical information was measured by SPSS software version 26 and the statistical level α<0.05 was considered. Results: Compared to the pre-test in the experimental group, there was a significant decrease in the variable of weight (p=0.01), body mass index (p=0.008), body fat percentage (p=0.002), TSH (p=0.005) and a significant increase in maximum oxygen consumption (p=0.002), T4 (p=0.01) was seen, but no significant difference was observed in the variable of waist circumference to hip circumference. In the inter-group comparison, there was no significant difference in all the variables in the pre-test, and in the post-test comparison, there was a significant decrease in the experimental group compared to the control group, but there was no change in the waist-to-hip ratio variable. Conclusions: These findings show that resistance aerobic exercise has an effect on selected indicators of body composition, maximal oxygen consumption, and thyroid hormones in sedentary, overweight and obese women with hypothyroidism.

        Introduction: The purpose of this study was to determine the difference between two methods of high-intensity aerobic and strength training on the levels of testosterone, cortisol, (IGF1) and immunoglobulin (IgG) in professional taekwondo athletes. Material & Methods: The present research method was semi-experimental and had a pre- and post-test approach. The statistical population of this research was the professional taekwondo athletes of Rasht city with an average age of 22 ± 1.5 years. To collect information on testosterone and cortisol levels by immunoassay method (GMB kit; (IGF1) by ELISA method and serum immunoglobulin G (IgG) values by nephlometry method (blood sampling) in three stages and three consecutive weeks (24 One hour after specialized Taekwondo training (pre-test), 24 hours after high-intensity strength training and 24 hours after high-intensity aerobic training (post-tests) in the fasting state from the subjects' brachial vein by a laboratory science specialist. was received and then two aerobic exercise protocols (80% Vo2Max) and high intensity strength (80% 1RM) were implemented on the sample people during two different sessions and for 45 minutes. Results: The findings showed that there is a difference between the effect of two methods of high-intensity aerobic training and high-intensity strength training on the levels of testosterone, cortisol, insulin-like growth hormone ( IGF1) and immunoglobulin (IgG) of professional Taekwondo athletes, there is a significant difference (p < 0.05). Conclusions: According to the findings, serum testosterone levels may increase slightly after high-intensity strength training and then high-intensity aerobic training. find Serum cortisol levels decrease after high-intensity aerobic training but increase after high-intensity strength training, and it is possible that insulin-like growth factor-1 (Igf1) serum levels decrease after high-intensity strength training. But after the high-intensity aerobic training test, there should not be many changes. Serum levels of immunoglobulin G have little changes and decrease after high-intensity aerobic and strength training. Manuscript profile

        Muscle pain after resistance activities, which occurs due to the destruction of sarcolema, increases the serum levels of LDH and CK enzymes as indicators of muscle damage. The results have shown that the use of food supplements such as glutamine can be useful in reducing the serum indicators of muscle damage. The aim of the present study is to determine the effect of glutamine supplementation on serum indicators of muscle damage, including the serum levels of LDH and CK enzymes following a session of resistance activity. The present experimental study was carried out using an animal model in the form of a 3 group&rsquo;s research design with a control group. To this end, 30 six-week-old adult male Wistar rats were kept under controlled conditions for 2 weeks and were then divided into three equal groups, including control, and resistance activity with/ without glutamine supplementation. The glutamine supplementation group received the prepared emulsion by gavage of 200 mg/kg of body weight. After five days, both experimental groups participated in a session of resistance activity (namely, climbing a smooth ramp with one and a half meters height and a 85&deg; decline) with 4 sets, 5 repetitions, 30 seconds of rest between repetitions and 2 minutes of rest between sets. The initial load was considered equal to 50% of the rats&#039; body weight. One-way analysis of variance and Bonferroni&#039;s post hoc test were used at a significance level of p &ge; 0.05. The levels of CK and LDH enzymes were different in groups. A five-day glutamine supplementation before performing a session of resistance activity can cause a lower increase in the serum levels of CK and LDH enzymes as serum indicators of muscle damage, which indicates the protective effect of glutamine in maintaining the integrity and structure of cell membrane.

        Abstract Objective: The present study aimed at the effect of two types of resistance and functional training programs on myostatin and follistatin of young active men. Materials and Methods: In the study, 45 active young men with an age range of 18 to 28 years were selected as available and placed in three groups of intense functional exercises, traditional resistance exercises and control. Bleeding was done in two stages: pre-Test (24 hours before the start of the intervention period) and post-test (48 hours after the end of the intervention period). The training phase took place in eight weeks and three sessions each week. The data collected was analyzed by T-dependent method, covariance and benfronian tracking test. Findings: The results of the present study showed that intense functional training and traditional resistance training had a significant effect on the reduction of myostatin in young active men. Participants in the intense performance training group were statistically lower in myostatin compared to participants in the traditional resistance training group. Intense functional training and traditional resistance training had a significant effect on the increase in follistatin in young active men. Participants in the intense performance training group were statistically higher than participants in the traditional follistatin resistance training group. Intense functional training and traditional resistance training had a significant impact on increasing the strength of the lower and upper limbs of active young men. Participants in the intense performance training group had statistically higher lower and upper limb strength compared to participants in the traditional resistance training group. Conclusion: Overall, the results of the present study showed that 8 weeks of traditional HIFT and resistance training improved protein synthesis factors and improved the performance of young athletes.
