The aim of this study was to investigate the role of information technology in adopting knowledge management in physical education faculties of Iran state universities. The statistical population of this study consisted of all board members of physical education faculties (N=150). As all the members were available, the sample equaled the population. The statistic used in data analysis was correlation (P≤0.05). This study used an applied, descriptive – analytical and method (p≤0.05) as well as structural equation modeling. A researcher-made knowledge management questionnaire (30 board members confirmed the reliability and 25 sport management professors confirmed the validity), review of related literature and field method were used to collect the data. The results showed that technology and IT infrastructures as well as the quality of speed to gain access to modern information and knowledge had the highest effect on knowledge detection (0.99). Personal computers in professors’ offices as well as access to internet and proper technological infrastructures had the highest effect on knowledge perspicuity (0.98). Connection infrastructures to accelerate information exchange and knowledge transfer had the highest effect on knowledge collaboration (0.99). Personal computers in professors’ offices as well as access to internet and proper technological infrastructures had the highest effect on knowledge evaluation (0.93). The effect of technology and information technology on knowledge issuance in physical education faculties had the highest effect on knowledge issuance (0.97).

The aim of this research is the study of influence of a football camping period on aerobic performance and efficiency indexes of respiratory organism.The 17 players of football team participated in this research (mean age 17.11±1.31).before participating in the practice period, they do increasing practice protocol to determine the maximal oxygen uptake, vVo2max, vLT and lung aerofication rate and equivalent of aerofication oxygen in two level of lactate threshold and the maximal oxygen uptake on treadmill that is joined to gas analyzer they participate in interrupted camping practice consist of 6/10 days camping. T test is used for analyzing the data. The results of research don’t show the meaningful difference. With comparing the performance in two tests, it seems the players don’t have enough readiness.

The aim of this research was to evaluate the existing condition of Iran physical education faculties and scientific centers and to present their strengths and weaknesses in comparison with the standards of university libraries. For this purpose, the conditions of these libraries were investigated using ‘goals and responsibilities, ‘human resource’, ‘organization and management’, ‘collection’, ‘organizing, ‘service’, ‘building and equipment’ and ‘budget’ indexes and then the obtained results were compared with the standards of Iran university libraries. The statistical population consisted of 10 university libraries and National Olympic Academy and SSRC libraries. To collect data, a questionnaire consisting of 68 questions in eight subscales was used. Another section of the questionnaire was allocated to personal information of libraries under study. The research used the application and field method. The obtained results were compared with ‘the standards of Iran university libraries’ and Excel and SPSS software was used to analyze the data. The results showed that Iran physical education university libraries and scientific centers had a proper condition regarding goals and responsibilities, organization and management, collection and library service while they did not have a proper condition regarding human resource, organizing library sources, building and equipment and especially budget when compared with the standards of university libraries.

The purpose of this research was to analysis about Performance management and curriculums of are teachers and students. Our sampling was 34 teachers and 137 student of physical education and sports science faculty of University of Tehran. In order to collect the data, we used questionnaire based on Likert scale. Mean, Percentage of frequencies, SD, K-S for normality and independent T-test use for analyzing the data and with spss11/5 software. The results indicated that there was no significant differences between the attitudes of two student groups (P=0/528) but the attitudes of two student groups with teachers were significant (P=0/000) and (P=0/000). Due to concerns about the weakness of the student’s skills necessary to participate in the labor market, the need to increase the number of specialist teachers, books and educational facilities are felt appropriate.

The aim of this study was to investigate the relationship between effort- reward imbalance and burnout among physical education teachers. Statistical samples were 189(89%) of teachers who had at least three year work experience in Kermanshah schools. Research design was cross- sectional using AMOS path way analysis. Participant completed demographic questionnaire, Maslach burnout inventory (MBI: Maslach, Jackson, & Leiter, 1996) and Siegris effort- reward imbalance questionnaire (ERIQ: Siegrist et al. 2004). Results showed there is significant relationship between effort- reward imbalance with over commitment. In addition, effort- reward imbalance had direct effect on emotional exhaustion and depersonalization. Moreover over-commitment had direct effect on emotional exhaustion. Therefore effort- reward imbalance could impact on teachers’ emotional exhaustion and depersonalization as core of burnout symptoms.

The purpose of this study was to compare the physiological Indices of Iranian elite female kayakers on treadmill and arm ergometer. Twelve Iranian elite female kayakers (age: 16.5±2 yrs, height: 166.7±4.4 cm, weight: 57.89±7.3 kg, body fat: 20.33±6 %) participated in this study. VO2max, heart rate and VO2 at lactate threshold, VO2 pulse (VO2/HR) and ventilation (VE) values measured by two increamental tests along with gas analization. Antropometric and body composition characters including height, sitting height, two hands distance, arm, thigh and leg lengths; arm, thigh, sholder and pelvis breadths; arm, thigh, chest, hip and leg girths; body fat percentage, musle mass and kayak performance evaluated by 12 kilometer kayaking test (K12 time) were also measured. Data were analyzed by t-student and Pearson correlation coefficient (α=0.05). There was significant correlation between all the physiological indices of kayakers in two test (p<0.05). Although VO2max measured by the arm ergometer was lower than VO2max measured by treadmill. In comparison with similar elite kayakers in other countries, Iranian elite female kayakers had lower height, weight and specially muscle mass. This findings can be a guidance for national coaches in selection of athletes who have suitable physiological, antropometric and body composition characteristics and as there were differences between Iranian elite female kayakers and their match in other countries, it is recommended to insert more resistance training within training programs of kayakers to increase strenght and muscle mass of their upper body.

in present era, efficiency and efficacy are the most important goal of organizations. Therefore, the purpose of present research is investigating the relationship between time management and creativity of physical education employees of Golestan province. Research this research is a field study and statistical population of it is composed of all employees of Golestan Province physical education offices (n= 180) of which 147 employees participated in this study. In order to evaluate creativity value of employees we used Amabile creativity questionnaire (1996). Time management skill was also evaluated through researcher made questionnaire which assesses time management based on 6 micro-scales: daily planning, confidence to long range planning, goal setting, control of time, tenacity and disorganization of plans. After using Calmograph Smirnoff and making sure of natural distribution of data (P > 0.05), in order to analyze the data we used t-test, multiple regression test to determine predicting variable of creativity and Peirson correlation coefficient in the level P < 0.05. the results of test indicated that there is a significant difference in long term planning (t= 2.35 & Sig = 0.004), time limitation management (t= 2.62 & Sig = 0.031), tenacity in plan execution (t= 3.71 & Sig = 0.006), disorganization in plans (t= 2.61 & Sig = 0.042) among two groups (P < 0.05), but in daily planning micro-scale (t= 1.47 & Sig= 0.08) and goal setting (t = 3.49 & Sig = 0.0671)no significant difference was observed. Also, the results of regression test indicated that the ability to manage time limitation (P < 0.01 & β = 0.27) and long term planning of employees (P < 0.01 & β = 0.23), the highest impact induced by employees’ creativity value.

The purpose of the study was to investigate the impacts of endurance, resistance and concurrent training on adiponectin resting levels of non-athlete men. Forty four obese non-athlete students (BMI > 25) voluntary participated in this study and were randomly based on BMI assigned to one of four groups: endurance training (ET, 22 ± 0/89 years, height 174/64 ± 4/72 cm, weight 90/55 ± 10/80 kg, N = 12); resistance training (RT, 21 ± 1/57 years, height 171/11 ± 5/51 cm, weight 92/22 ± 15/85 kg, N = 9); concurrent training (CT, 21/38 ± 2/06 years, height 173/65 ± 7/07 cm, weight 86/61 ± 15/05 kg, N = 13); and control group (CG, 21/44 ± 1/13 years, height 175/61 ± 5/09 cm, weight 90/00 ± 14/05 kg, N = 9). After primary measurement and 48 hours after the last training session blood samples were drawn with the subjects in the fasting and resting state for determination of the basic level of adiponectin. The subjects participated in E, R and C training for 8 weeks. The ET group ran 25 – 40 minutes a day ansd 3 days per week at 65 - 85% maximum heart rate. The exercise training session for the RT group consisted of three sets of 10 – 15 repetitions of weight training exercises of primary muscles group that increased progressively and repeated three sessions per week (including: chest press, squat, opening leg, knee flexion and extension, chest dumbbell press, leg press, seated rowing, and standing rowing). The CT group exactly trained the sum of the ET and RT groups. Correlated samples t-test and one way analysis of variation were used to compare within and between groups differences respectively. The result of the present study showed that after 8 weeks training the diponectin levels of subjects increased in three groups of training but this increase was not significant. The level of adiponectin in CT group increased more than ET and RT groups. Also, there were no significant differences in content of adiponectin among groups. In general, slightly increases in adiponectin levels in training groups, especially CT group may indicate the most potential of CT group in increasing the levels of adiponectin in non-trained men. However there are need more related researches to indentify the effect of concurrent training.
