The aim of this study was to examine the positive effects of forced andvoluntary exercises as a non-pharmacological factor on modified behaviorsdue to stress of separation from mother. In the present study, 48 male babyrats were selected and separated from their mothers from day 2 to 14 for 180minutes. On the 21st day, these rats were randomly divided into 4 groups.The groups included maternal stress, control, treadmill, running wheel (RW).The first group experienced stress of separation from their mothers from day2 to 14 and the control group was kept from the beginning with theirmothers. The exercise groups also began to exercise since their 21st birthday. Then, the groups conducted behavioral anxiety and rodent depressiontests including EPM, Splash, FST, and Open Field. The obtained data werestatistically analyzed by t and ANOVA methods at a significance level(P<0.05). Behavioral tests showed that the stress of separation from themother caused depression behaviors. On the other hand, voluntary exercisecaused antidepressant effects compared with the stress group while nosignificant changes were observed between the effect of forced exercise andthe stress group. The results showed that exercise, especially voluntaryexercise, reduces stress during adolescence, and reduces depression andanxiety behaviors in adulthood.

Physical activity has physiological, psychological, and social positive effects. However, the relationship between physical activities and depression of the elderly in the country is unknown. This study was designed to examine the relationship between physical activity and depression. The statistical population consisted of the elderly of Arak city in 2013 and 263 subjects participate in the study. Data were collected with demographic characteristics questionnaire, Geriatric Depression Scale-short form, and Rapid Assessment of Physical Activity (RAPA) and analyzed with Pearson correlation coefficient, linear regression analysis, t test, ANCOVA test with SPSS-16 software. Findings indicated a significant relationship between depression and age, employment, fall history, economic status, physical activity, education, perceived health (P≤0.05). Variables of physical activity, fall history in the past year, economic status, and perceived health predicted depression (R2=0.358; P≤0.05). Mean score of physical activity in the male elderly was significantly higher than their female counterparts, and mean score of physical activity in 60-69-year-old group was significantly higher than their counterparts in 70-79 and ≤ 80-year-old groups (P≤0.05). There were no significant differences between age and gender and mean score of depression. These findings emphasize the importance of the effect of physical activity on depression in the elderly.

The purpose of this study was to investigate general health condition, outbreak of depression and body mass index (BMI) in athlete and non-athlete students of Tehran University. Both female and male junior students participated in this study and 200 students, 50 athletes and 50 non-athletes were selected. In order to determine general health and outbreak of depression, questionnaires of general health and Beck's depression test were used, and in order to determine BMI, height and weight of the subjects were measured. In order to analyze the data, two-way ANOVA test and Pearson correlation coefficient were used. The results of this study showed no significant difference in the average value of BMI between athlete and non-athlete students based on their gender (P=0.09), but there was a significant difference in BMI between female and male students. No significant interaction was observed between gender and physical activity in BMI index. There was a significant difference in general health between athlete and non-athlete students based on their gender (P=0.007). There were no significant differences among general health subscales, BMI and Beck scores of students based on their gender and physical activity. However, there was a significant relationship between GHQ28 subscales and Beck scores based on gender and physical activity.
