Improving physical fitness and emotional well-being in adolescents of low socioeconomic status in Chile: results of a school-based controlled trial.
Regular physical exercise may improve a variety of physiological and psychological factors in depressive persons. However, there is little experimental evidence to support this assumption for adolescent populations. We conducted a randomized controlled trial to investigate the effect of physical exercise on depressive state, the excretions of stress hormones and physiological fitness variables in adolescent females with depressive symptoms.
                Forty-nine female volunteers (aged 18-20 years; mean 18.8 +/- 0.7 years) with mild-to-moderate depressive symptoms, as measured by the Centre for Epidemiologic Studies Depression (CES-D) scale, were randomly assigned to either an exercise regimen or usual daily activities for 8 weeks. The subjects were then crossed over to the alternate regimen for an additional 8-week period. The exercise program consisted of five 50-min sessions per week of a group jogging training at a mild intensity. The variables measured were CES-D rating scale, urinary cortisol and epinephrine levels, and cardiorespiratory factors at rest and during exercise endurance test.
                After the sessions of exercise the CES-D total depressive score showed a significant decrease, whereas no effect was observed after the period of usual daily activities (ANOVA). Twenty-four hour excretions of cortisol and epinephrine in urine were reduced due to the exercise regimen. The training group had a significantly reduced resting heart rate and increased peak oxygen uptake and lung capacity.
                The findings of this study suggest that a group jogging exercise may be effective in improving depressive state, hormonal response to stress and physiological fitness of adolescent females with depressive symptoms. Previous observational and interventional studies have suggested that regular physical exercise may be associated with reduced symptoms of depression. However, the extent to which exercise training may reduce depressive symptoms in older patients with major depressive disorder (MDD) has not been systematically evaluated.
                To assess the effectiveness of an aerobic exercise program compared with standard medication (ie, antidepressants) for treatment of MDD in older patients, we conducted a 16-week randomized controlled trial.
                One hundred fifty-six men and women with MDD (age, > or = 50 years) were assigned randomly to a program of aerobic exercise, antidepressants (sertraline hydrochloride), or combined exercise and medication. Subjects underwent comprehensive evaluations of depression, including the presence and severity of MDD using Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria and Hamilton Rating Scale for Depression (HAM-D) and Beck Depression Inventory (BDI) scores before and after treatment. Secondary outcome measures included aerobic capacity, life satisfaction, self-esteem, anxiety, and dysfunctional cognitions.
                After 16 weeks of treatment, the groups did not differ statistically on HAM-D or BDI scores (P = .67); adjustment for baseline levels of depression yielded an essentially identical result. Growth curve models revealed that all groups exhibited statistically and clinically significant reductions on HAM-D and BDI scores. However, patients receiving medication alone exhibited the fastest initial response; among patients receiving combination therapy, those with less severe depressive symptoms initially showed a more rapid response than those with initially more severe depressive symptoms.
                An exercise training program may be considered an alternative to antidepressants for treatment of depression in older persons. Although antidepressants may facilitate a more rapid initial therapeutic response than exercise, after 16 weeks of treatment exercise was equally effective in reducing depression among patients with MDD. To evaluate the effects of a physical exercise programme for children with asthma on an outpatient basis.
                Intervention study: a randomized pretest-post-test control group design.
                Forty-seven children with clinically diagnosed asthma participated in the intervention study, including 34 boys and 13 girls, from 8 to 13 years of age (mean age 10.6).
                The physical exercise programme consisted of regular group exercises and home exercises for a period of three months. It was based on a theoretical model describing the relationships between physical competence (condition), perceived physical competence, self-esteem and coping behaviour.
                Maximum incremental exercise test, endurance test, the Self-Perception Profile for Children (CBSK), the Asthma Coping Test (ACBT), lung function and exercise-induced bronchoconstriction.
                The results showed significant effects of the intervention programme on physical condition. There was a significant improvement of 15 W on the maximal workload (Wmax) (p < 0.001), of 7% on VO2max (oxygen uptake) (p = 0.002) and a significant decrease on heart rate submaximal of 6% (p = 0.001). There was also a significant improvement of 50% in running time measured with the endurance test (p = 0.021). Furthermore, a significant effect of the intervention was seen on coping with asthma (p = 0.003).
                It was concluded that participation in the physical exercise programme not only enhanced physical fitness, but also improved coping behaviour with asthma. Two clinical trials have been conducted in a sample of depressed patients to determine whether the addition of an aerobic exercise programme to their usual treatment improved outcome after 12 weeks. In the first trial, an aerobic exercise group had a superior outcome compared with a control group in terms of trait anxiety and a standard psychiatric interview. A second trial was then conducted to compare an aerobic exercise programme with low intensity exercise. Both groups showed improvement but there were no significant differences between the groups. In neither trial was there any correlation between the extent of change in the subjects' physical fitness due to aerobic exercise and the extent of the improvement of psychiatric scores. To evaluate the short-term effects of exercise in patients with major depression.
                Prospective, randomised, controlled study.
                A university hospital.
                A consecutive series of 38 inpatients with a major depression episode undergoing standard clinical antidepressant drug treatment.
                Patients were randomly assigned to an exercise (walking, n = 20) or placebo (low-intensity stretching and relaxation exercises, n = 18) group. Training was carried out for 10 days. Main outcome measurements: Severity of depression assessed with the Bech-Rafaelsen Melancholy Scale (BRMS) and the Center for Epidemiologic Studies Depression scale (CES-D).
                After 10 days, reduction of depression scores in the exercise group was significantly larger than in the placebo group (BRMS: 36% v 18%; CES-D: 41% v 21%; p for both = 0.01); the proportion of patients with a clinical response (reduction in the BRMS scores by more than six points) was also larger for the exercise group (65% v 22%, p<0.01).
                Endurance exercise may help to achieve substantial improvement in the mood of selected patients with major depression in a short time. Depression is common in later life.
                To determine whether exercise is effective as an adjunct to antidepressant therapy in reducing depressive symptoms in older people.
                Patients were randomised to attend either exercise classes or health education talks for 10 weeks. Assessments were made "blind" at baseline, and at 10 and 34 weeks. The primary outcome was seen with the 17-item Hamilton Rating Scale for Depression (HRSD). Secondary outcomes were seen with the Geriatric Depression Scale, Clinical Global Impression and Patient Global Impression.
                At 10 weeks a significantly higher proportion of the exercise group (55% v. 33%) experienced a greater than 30% decline in depression according to HRSD (OR=2.51, P=0.05, 95% CI 1.00-6.38).
                Because exercise was associated with a modest improvement in depressive symptoms at 10 weeks, older people with poorly responsive depressive disorder should be encouraged to attend group exercise activities. We conducted a proof-of-concept, randomized, controlled trial to investigate the effects of a supervised exercise therapy intervention on psychopathologic outcomes in obese adolescents.
                The participant sample consisted of 81 adolescents (age: 11-16 years) who had been referred to a children's hospital for evaluation of obesity or who responded to a community advertisement. Participants were assigned randomly to exercise therapy, an equal-contact exercise placebo intervention, or usual care. Intervention participants attended 3 one-on-one sessions per week for 8 weeks and then completed a home program for another 6 weeks. Outcomes included self-perceptions (self-esteem), depression, affect, physical activity, aerobic fitness, and BMI.
                A total of 18 of 81 participants were categorized as morbidly obese (BMI SD score: > 3.5; adult equivalent BMI: > or = 40). At baseline, 30.3% of participants had a Children's Depression Inventory score of > or = 13, and 27% reported recent suicidal ideation. Repeated-measures mixed analysis of covariance (controlling for baseline scores) revealed significant changes in physical self-worth, associated measures of self-esteem, and physical activity over time, consistently favoring exercise therapy. There were no significant changes in BMI.
                Findings confirmed psychopathologic conditions as a serious health concern in obese and morbidly obese adolescents. Our study is the first randomized, controlled trial to demonstrate that a brief supervised exercise therapy intervention has the potential to improve psychopathologic outcomes significantly and to increase physical activity in obese adolescents, relative to usual care. Since physical exercise programs have the potential to help cancer patients regain physical fitness and may exert a range of positive consequences for recovery and psychological well-being, the impact of a physical exercise program was investigated in this prospective study.
                Women with primary nonmetastatic breast cancer after a minimum 4-week period post chemotherapy and/or radiotherapy completion were randomly assigned to one of 2 groups: intervention group (IG) (n = 30) and waiting group (WG) (n = 28). The 10-week twice weekly exercise group program consisted of gymnastics, movement games, relaxation, walking, and jogging. Anxiety, depression, body image, and quality of life were measured using standardized questionnaires. Maximal oxygen uptake (VO(2)max/kg) was assessed as a measure of physical fitness.
                Patients in the IG improved significantly over time with regard to anxiety (p = 0.03, d = 0.45), depression (p = 0.05, d = 0.43), individual body image (p = 0.006, d = 0.44), and VO(2)max/kg (p < 0.001, d = 0.50), whereas no improvements were observed in the WG. However, this randomized controlled trial failed to demonstrate significant intervention effects in quality of life and social body image.
                This prospective study provided evidence for the effectiveness of a 10-week physical exercise intervention to significantly improve psychosocial wellbeing, individual body image, and physical fitness.

Among adolescents, physical activity is associated with benefits in the prevention and control of emotional distress, and improvement of self-esteem. Countries in transitional epidemiological scenarios, such as Chile, need to develop effective strategies to improve physical activity as a way to face the epidemic of chronic diseases. The objective of this study was to evaluate the effects of a school-based physical activity program on physical fitness and mental health status of adolescents living in a low socioeconomic status area in Santiago, Chile. A quasi-experimental design was used to evaluate the effects of the program over one academic year. The study included 198 students aged 15 years old. Two ninth grade classes were randomly selected as the intervention group, with two classes of the same grade as controls. A social planning approach was used to develop the intervention. The program was designed and implemented based on student preferences, teachers' expertise and local resources. Changes in physiological and mental health status were assessed. After the intervention, maximum oxygen capacity achieved a significant increase of 8.5% in the intervention versus 1.8% in the control group (p < 0.0001). Speed and jump performance scores improved significantly more in the intervention versus the control group (p > 0.01). Anxiety score decreased 13.7% in the intervention group versus 2.8% in the control group (p < 0.01), and self-esteem score increased 2.3% in the intervention group and decreased 0.1% in the control group after the end of the program (p < 0.0001). No significant change was observed in the depressive score. Student participation and compliance with the program was > 80%. To conclude, a school-based program to improve physical activity in adolescents of low socioeconomic status, obtained a high level of participation and achieved significant benefits in terms of physical fitness and mental health status.
Whilst there appears to be a small effect in favour of exercise in reducing depression and anxiety scores in the general population of children and adolescents, the small number of studies included and the clinical diversity of participants, interventions and methods of measurement limit the ability to draw conclusions. It makes little difference whether the exercise is of high or low intensity. The effect of exercise for children in treatment for anxiety and depression is unknown as the evidence base is scarce.
