Background and Aim: Beach soccer as a new exciting and popular field of sport is spreading rapidly around the world. However, so far, limited accurate and documented information is available about the physical and physiological needs of this sport. The purpose of this study was to investigate the changes in resting levels of some inflammatory, muscle damage, aerobic and anaerobic indices of beach soccer players in the pre-season, mid-season and end of the premier league season. Materials and Methods: In this quasi-experimental study with repeated measures design, 13 elite beach soccer players (Mean± SD: age 24.64±4.01 year, body mass index 22.76±2.36 kg/m2 and maximum oxygen consumption 38.60±5.48 ml/kg/min) were selected. Measurements of aerobic and anaerobic power and alanin amino teransferase (ALT), aspartat amino teransferse (AST), certain phosphokinase (CPK) and lactate dehydrogenase (LDH) indices were measured in the 98-99 pro league in pre-season, mid-season and also at the end of the season. The repeated measure analysis of variance and Bonferroni tests were used to examine the changes at the significant level of p<0.05. Results: Significant increase in ALT (p=0.04) and also decrease in anaerobic power (p=0.001) was observed from pre-season to the end of the season. LDH levels showed a significant increase in the mid-season compared to the pre-season (p=0.04) and as the same the significant decrease also was found at the end of the season compared to the mid-season (p=0.01). However, no significant changes were observed in AST (p=0.50), CPK (p=0.15) and aerobic power (p=0.11) during the competition season. Conclusion: Due to the physiological pressure for beach soccer players at different stages, it is recommended that players in this field should be monitored for biochemical and functional parameters during the competition season, and based on that, training, nutrition and recovery programs could be optimized.

Background and Aim: The purpose of this study was to identify the effects of ginseng supplementation and six weeksof resistance training on aerobic and anaerobic factors of non-active students at the university of Shahrood. Materialsand Methods: In this way, 50 students of Shahrood university with an age average of 19±2 years and the body mass index average of 22±3 kg/m2 voluntarily participated in the study. The subjects were divided randomly into four groups including training+supplement (13 people), training+placebo (13 people), supplement (12 people), and control (12 people) groups. Training groups were performed a designed protocol three times per week for 6 weeks. Before and after the training program, the Bruce aerobic test, the Wingate anaerobic test and body composition were measured. The Kolmogorov-Smirnov test was used for evaluating of normal distribution of data and then the paired t-test and repeated measure ANOVA test (4×2) were applied for detection of significant differences (p<0.05) between groups. Results: The peak anaerobic power (p=0.02) and maximum aerobic power (p=0.001) were significantly increased in the training groups, however, average aerobic power (p=0.12), minimum aerobic power (p=0.09) and fatigue index (p=0.32) did not show any significant differences between groups. Conclusion: Compared to the resistance training intervention, resistance training along with ginseng supplement may have a greater role in improving aerobic and anaerobic power in non-active male students.

Background and Aim: The aim of the current study was to compare the aerobic and anaerobic power, body mass index and fat distribution percent in athletic and non-athletics students in Islamic Azad University-Kashmar branch. Materials and Methods: 30 elite athlete students (20-25 years) involving in different sports and 30 non -athlete students as control group were randomly selected. The aerobic power was measured using an ergometer, Sargent jumping test also was used to measure anaerobic power. Caliper was also used to measure percent distribution of body fat from chest, abdomen and hip regions. The body mass index (BMI) calculated by dividing weight (kg) by the square of height (meter). Independent t- test used to analyze data with a significant level at p≤ 0.05 with SPSS software. Results: The result of current study showed that there is no significant difference between BMI and aerobic power in athlete students and non - athlete students. However, anaerobic power of athlete students was significantly higher (p=0.03) than non-athlete students. Conversely, percent body fat in non - athlete students was significantly greater (p=0.001) than the athlete students. Conclusion: sports exercise in student career and university campus increases the anaerobic power and also decreases subcutaneous fat in athlete than non-athlete students.
