In order to study of the effects of vigorous and moderate aerobic exercises on the general health of non-active men, 43 individuals volunteered in this research. They were divided into two experimental groups and a control group by Simple random sampling.  Duration of training was 8 weeks and subjects 3 sessions per week and each session 30-45 minutes performed assigned aerobic exercises. Experimental group I (n=15) carried out vigorous aerobic exercise, and experimental group II (n=16) carried out moderate aerobic exercise, at 80-85 and 60-65% of maximal reserve heart rate respectively. Control group (n=12) didn’t perform any physical activity through research. General health of participants were evaluated by general health questionnaire (GHQ-28) of Goldber & Hillier in the initial and after 8 weeks of exercise. We applied one-way analysis of variance and LSD test for revelation results of study.  Results showed significantly  improvement in physical signs (P<0.04), anexiety and sleeping disorder (P<0.03), along with significantly increases in maximal oxygen uptake (P<0.05) and significantly decreases in waist circumference (P<0.04) after 8 weeks of vigorous aerobic exercises. In addition, we observed an inclination for improvement in the general health of moderate aerobic exercise group.  Based on the results, performing of vigorous aerobic exercise upto 80-85% of maximal reserve heart rate can improve general health, physical fitness and body composition of non- active men.

Production of the reactive oxidative species (ROS) as free radicals resaults in oxidative stress and therefore cell structural damage following the exercise. This study aimed to investigate the effect of a single endurance exercise session on the lipid peroxidation biomarker, malondealdehyde (MDA) and serum total antioxidant capacity (TAC) in wistar rats. Thus 14 wistar rats aged 4 month were assigned randomly into one of 2 groups: rest (n=7), and endurance exercise (n=7). All groups were subjected a familiarization treadmill protocol for two weeks that started with walking and progress to the running speed 10 m/min. Finally, rats in endurance exercise group exercised at 70%vo2max. The running speed were 25 m/min at a gradient 5% in endurance group. Blood samples taken following the exercise from rested and exercised groups.  Serum total antioxidant capacity (TAC) and serum malondealdehyde (MDA), were measured. Results showed: The MDA increased significantly following endurance exercise in the endurance group compare to the rest group (p</01). The TAC increased significantly following endurance exercise in the endurance group compare to the rest group (p</05).

The objective of this research is the comparison on Conflict Management style And leadership style of Physical Education Managers In Education Office And In Physical Education Office In Mazandaran Province. The method of study is as descriptive research. The gathering of data to be through a questionnaire. The questionnaire reliability and validity were achieved at researcher and others. (Fred Luthans & OCCI[1] standard questionnaire) to do so , 17 Physical Education Managers In Education Office and 32 Physical Education Managers In Physical Education Office were selected to population. Both the Conflict Management style and leadership style questionnaire were perfected to objectives. Data analysis were done using descriptive statistics and Independent Sample Test, T tests. For the analysis of data is used to spss (13) and Excel 2003 soft ware . The following results were obtained: 1) There are a relation between Conflict Management style And leadership style of Physical Education Managers In Physical Education Office (P2) There are a relation between Conflict Management style And leadership style of Physical Education Managers In Education Office (P3) There are no significant difference between Conflict Management style in Physical Education Managers (P4) ) There are a significant difference between leadership style in Physical Education Managers (P Key words: Conflict Management styles , Employee-oriented leadership style , task-oriented leadership style.

The purpose of this study was the estimate the blood lipid variables use of %BF and LBM indicators of  young studenst. for this reason, 31 number of boy student in physical education, voluntarily was chosed.Their age , hight ,weight, percent of body fat,Lean body mass of subjects was, 23.872.06 years, 173.586.81 centimeters, 64.143.96 kilograms,9/322/30 percent, 58.373.51 kilograms. The acquired data were analyzed by using pearson correlation coefficient and correlation coefficiens meaningful test (tr). Conclutions showed that, There was not meaningful correlation among percent of body fat with cholesterol(p=0.112), Triglycerid (p=0.700), LDL-C(p=0.127) and HDL-C(p=0.550) . While There was meaningful correlation among Lean body mass with LDL-C(p=0.016) ,There was not meaningful correlation among Lean body mass with TG (p=0.778), TC(p=0.119), HDL-C(p=0.669). with due attention to Conclutions this study can conclude,That can not estimate the blood Lipid variables to make use of %BF and LBM indicators.

It has been suggested that regular aerobic training is resulted to hematological changes. However, there is not a general agreement about the effect of a single session of weight circuit exercise. The purpose of this study was to investigate weight circuit exercise on hematological responses. Fourteen physical education students (age 20.57 ± 0.51 years, 78.25 ± 5.01 in weight, 175± 2.2 cm in height, and 25.27± 1.18 kg/m2) volunteered to participate in the present study. Subjects were asked to perform nonstop weight circuit exercises (10exercise at 60% 1RM, 20s time for each, 3 circuits with 3min rest between circuits). Blood samples were taken at pre and immediately after exercise while the subjects were overnight fast (at least 12h). White blood cells (WBC) and its related variables red blood cells and its related variables, platelets (PLT), RDW, MPV, P-LCR, and PDW were measured. Data were analyzed by using paired sample student T-test. Data were given as a Mean ± SE. The differences were accepted at alpha £0.05. Significant changes were found in WBC counts, MCV, PLT, RDW, MPV, and P-LCR. RDW significantly decreased. Insignificant changes were observed in other mentioned variables. The present findings indicate that single weight circuit exercise can be accounted as a stimulus for hematological responses. Further research need to clarify mechanisms which are involved such changes.
