Background and purpose: Recent reports suggest that increased homocysteine is a risk factor for heart disease. On the other hand, regular exercise and supplementation of omega-3 fatty acids have been effective in reducing these diseases. The purpose of this study was to evaluate the interaction effect of 8 weeks of aerobic training and omega-3 fatty acid supplementation on plasma homocysteine concentration in elderly men. Materials and methods: The statistical sample for this experimental study consisted of 36 male non-athletes in the age range of 57.37±3.37 years. They were selected from Genaveh, Iran, and randomly divided into 4 groups: exercise with omega-3 supplements, exercise with placebo, omega-3 supplementation, and placebo intake. The 8-week endurance exercise program included 3 sessions per week with pre-determined duration (30-45 minutes) and intensity (55-70% HRmax). Daily dosage of omega-3 fatty acid supplementation was 2000 mg. Blood samples were taken after 14 hours of fasting before the study and 48 hours after the last training session. Results: The results showed that, despite a decline by 3.6% in the exercise + omega-3 fatty acids group, 12.4% in the placebo + exercise group (due to higher basal values of this group), and 2.8% in the omega-3 supplement group, moderate-intensity aerobic exercise and omega-3 fatty acid supplementation could not create a significant decrease in plasma homocysteine concentration (p≥0.05). Conclusion: This study showed that aerobic exercise and omega-3 fatty acid supplementation are associated with a non-significant but tangible decrease in plasma homocysteine concentration as a new risk factor for cardiovascular diseases.

Background and Purpose: Addict women face more mental problems than healthy women، and the issue is less attended. Applying inexpensive، easily accessible preventive measures like aerobic training can improve their mental health. The present study was to investigate the effect of aerobic training on the mental health of addict women in the central prison of Zahedan، Iran.
Methods and Materials: This experimental study involved the addict women in the central prison of Zahedan، Iran in 2008. Thirty addict women were randomly selected and assigned into two equal groups (15 controls and 15 experimental). The Goldberg General Health Questionnaire (GHQ 28) and Demographic Characteristics Questionnaire were used for Data collection. The experimental group was trained for 8 weeks، three weekly sessions of 45 minutes. Both groups completed the questionnaires before and after the 8-week training for the evaluation of their mental health status. The data were analyzed in SPSS 15 using descriptive statistics (frequency، mean and standard deviation) as well as the dependent and independent t-test.
Results: Results showed that after eight weeks of aerobic training program، symptoms significantly improved: physical symptoms (from 12.20±6.37 to 4/±53±2/83)، anxiety (from 14.47±4.50 to 4.33±2.13)، depression (from 11.67±6.78 to 3.60±3.25) and mental health (from 48.20±15.50 to 18.87±6.71) (p≤0.05). However، the social functioning of the participants did not significantly change (from 10.33±4.43 to 7.70±3.80).
Conclusion: The results indicated aerobic training had an effective role in improving the mental health of addict women.
