During the Covid-19 pandemic, the use of online sports programs became popular. The purpose of this study was to investigate the effect of eight weeks of online body balance program on anxiety, depression, and aggression of children with attention deficit/hyperactivity disorder (ADHD). Body balance is a sport based on yoga, tai chi, and Pilates. The present study was a semi-experimental and applied type of study. The participants of the present study were 30 volunteer children with ADHD who were divided into two experimental (15 people) and control (15 people) groups by random assignment method. Aggression, depression, and anxiety variables were evaluated by Bass and Perry questionnaire, Maria Kvas children's depression questionnaire, and Revised Children's Manifest Anxiety Scale. The experimental group performed online body balance training for 8 weeks (3 sessions per week for 60 minutes) online, and the control group did their current activities. In order to investigate intra-group and inter-group differences, repeated measures ANOVA at the error level of 0.05 was used by SPSS software. The results showed there was significant difference in the average level of symptoms of depression, anxiety and aggression in the pre-test and post-test stages (P≤0.05), between the two control and experimental groups (P≤0.05) and the interaction effect of time and group (P≤0.05). The results of Tukey's test showed that there was a significant reduction of these symptoms between the two experimental and control groups in the variables of depression symptoms (-5.500), anxiety symptoms (-5.133) and aggression symptoms (-13.133). Based on the results of this research, eight weeks of body balance training reduced depression, aggression and anxiety symptoms in 7-9 year old children with attention deficit/hyperactivity disorder. Therefore, the improvement of mental disorders caused by this disease in children following the body balance exercise program emphasizes the importance of using this intervention method for children with ADHD.

The present study seeks to compare life satisfaction, happiness and self-esteem of female athletes and non-athletes aged 20 to 65 years in Tabriz. The present study is a causal-comparative study. The statistical population of the present study was all female athletes and non-athletes in the age range of 20-65 years in Tabriz. From this statistical population, 349 female athletes and 135 non-athletes were selected as a sample using Morgan Table and cluster random sampling method. Cooper-Smith standard self-esteem, Satisfaction with Life Scale (SWLS) and Oxford Happiness (OHI) questionnaires were used in this study. The results of independent t-test, one-way analysis of variance and Friedman test showed that women athletes have higher life satisfaction, happiness and self-esteem than non-athletes. Also, with increasing duration of sports activities, women’s rate of happiness is also on the rise, and the first five years of exercise have had the greatest impact on women's self-esteem.

Background: Exposure to high altitude causes significant stress in the functioning of cardiovascular and respiratory systems.Aim: The aim of this study was to investigate the changes in systolic and diastolic blood pressure (BP), heart rate (HR) and pulmonary volumes during the classic ascent of Damavand 5671 m peak.Materials and Methods: 14 healthy male climbers (age = 23.85±5.93 years, height = 175.5±5.91 cm, weight =71.35±8.20 kg) participated voluntarily in this study. BP, HR and lung volumes were measured in basic (2000 M), BC (3100 m) the first day, C1 (3650 m) the first day, BC (3100 m) the second day after the one-night stopover, C1 (3650 m) the second day, C2 (4100 m) the second day, C2 (4100 M) third day after the one-night stopover, C3 (5000 m) and, peak (5671 m). Data were compared by repeated measures test at the significant level of P≤0.05 and Bonferroni post hoc test.Results: The results of repeated measures analysis were significant for HR, systolic BP, diastolic BP and MVV (P<0.05), but not significant for FVC and FEV1 (P≥0.05). BP was high in the base camp and the first camp and gradually decreased. HR continued to increase significantly with increasing altitude. MVV increased with increasing altitude and is reduced after the one-night stopover in each height.Conclusion: It can be concluded that climbing with classic method increased the HR and decreased systolic and diastolic BP of climbers. It was able to induce adaptation in lung volumes of climbers.

Background: Housewives build a significant part of society. They play a key role in strengthening the foundation of the family and nurturing the next generation of any country, so it is very important to pay attention to mental health of this population.   Aim: This study investigated effects of a period of Hatha yoga-based mindfulness practice on distress tolerance and subjective wellbeing of housewives. Materials and Methods: Participants were 38 housewives between 31 to 52 years who were randomly divided into two experimental groups including face-to-face (i.e., presence on the grass, n=17) and online (via Sky room, n=21). A 6-week Hatha Yoga-based mindfulness training was held simultaneously in twelve sessions for both groups. Distress Tolerance Scale (DTS) and Keyes and Magyar-Moe’s Subjective Well-being Scale were used. Results: The results of analysis of covariance showed that all subscales of distress tolerance and subjective well-being of housewives in the face-to-face group were significantly higher than the online group. Moreover, the results of paired t-test showed that the means of post-test of all subscales of distress tolerance and subjective well-being of housewives were significantly higher than the means of pre-test. But in the online group, the means of pre-test and post-test did not differ significantly in all variables. Conclusion: Our findings emphasize that, in order to improve metacognitive processes, yoga-based mindfulness training in online method cannot replace face-to-face method.
