Associations between sedentary behaviour and metabolic parameters in patients with schizophrenia

This study examined the association between sedentary behaviour and metabolic parameters among patients with schizophrenia. A total of 76 patients and 38 healthy age-, gender- and BMI-matched volunteers were included. Participants were asked for their overall sitting and physical activity behaviour using the International Physical Activity Questionnaire. Patients were additionally screened for psychiatric symptoms and extrapyramidal side-effects of antipsychotic medication. On average, patients with schizophrenia spent 8.5h per day sitting (versus 6.21h in healthy controls). Patients sitting more than 10.4h per day had a higher BMI, waist circumference and fasting glucose concentrations and experienced more negative and cognitive symptoms than those sitting less than 5.8h per day. Overall sitting time was associated with a significantly greater likelihood of metabolic syndrome. A stepwise backward-elimination multivariate regression analysis demonstrated that sitting time is a significant predictor for BMI. Current results suggest patients with schizophrenia may benefit from reducing total sitting time.

Effects of an Exercise Programme on Anxiety in Adults with Intellectual Disabilities.

Although high anxiety is common in people with intellectual disabilities (ID) and the anxiolytic effects of exercise have been systematically recognised in clinical and non-clinical populations, research is scant concerning the role played by exercise on anxiety in people with ID. The purpose of this study was to investigate the effects of a 12-week exercise programme on anxiety states in a group of adults with ID. Twenty-seven individuals with mild to moderate ID were randomly assigned to an exercise group or a control group. The Zung Self-Rating Anxiety Scale adapted for individuals with ID and the State-Trait Anxiety Inventory form Y were used to assess trait and state anxiety. In comparison with the control group, the anxiety scores of people in the exercise group decreased significantly over time.

Relationships between Physical Self-Concept and Physical Fitness in Italian Adolescents

Physical self-concept exerts a central role in adolescence. In this phase of life, individuals experience many physical, mental, and emotional changes, and sex differences become evident. The purpose of this study was to examine the relationships between physical self-concept and actual indicators of physical fitness among youth in early adolescence. A total of 103 Italian boys and girls, ages 12 to 15 years (M = 13.2, SD = 0.7) were studied. Physical self-concept was assessed using the Physical Self-Description Questionnaire, EUROFIT tests were used to measure physical fitness, and BMI was calculated based on height and weight measurements. Results showed several significant correlations between the variables, revealed some sex differences on physical self-concept and fitness, and indicated significant correlations between EUROFIT scores and physical self-concept variables.

An impaired health related muscular fitness contributes to a reduced walking capacity in patients with schizophrenia: a cross-sectional study

BackgroundPatients with schizophrenia report muscle weakness. The relation of this muscle weakness with performing daily life activities such as walking is however not yet studied. The aim of this study was to quantify walking capacity and health related muscular fitness in patients with schizophrenia compared with age-, gender and body mass index (BMI)-matched healthy controls. Secondly, we identified variables that could explain the variability in walking capacity and in health related muscular fitness in patients with schizophrenia.MethodsA total of 100 patients with schizophrenia and 40 healthy volunteers were initially screened. Eighty patients with schizophrenia (36.8±10.0 years) and the 40 age-, gender- and body mass index (BMI)-matched healthy volunteers (37.1±10.3 years) were finally included. All participants performed a standing broad jump test (SBJ) and a six-minute walk test (6MWT) and filled out the International Physical Activity Questionnaire. Patients additionally had a fasting metabolic laboratory screening and were assessed for psychiatric symptoms.ResultsPatients with schizophrenia did have lower 6MWT (17.9%, p<0.001) [effect size (ES)=−1.01] and SBJ (14.1%, p<0.001) (ES=−0.57) scores. Patients were also less physically active (1291.0±1201.8 metabolic equivalent-minutes/week versus 2463.1±1365.3, p<0.001) (ES=−0.91) than controls. Schizophrenia patients with metabolic syndrome (MetS) (35%) had a 23.9% lower (p<0.001) SBJ-score and 22.4% (p<0.001) lower 6MWT-score than those without MetS. In multiple regression analysis, 71.8% of the variance in 6MWT was explained by muscular fitness, BMI, presence of MetS and physical activity participation, while 53.9% of the variance in SBJ-score was explained by age, illness duration, BMI and physical activity participation.ConclusionsThe walking capacity and health-related muscular fitness are impaired in patients with schizophrenia and both should be a major focus in daily clinical practice and future research.

Exercise intervention to reduce depressive symptoms in adults with intellectual disabilities.

People with intellectual disabilities are often reported as having depressive symptoms. Although the antidepressant effect of exercise has been systematically recognized, research concerning the role of exercise on depressive symptoms in people with intellectual disabilities is still scant. A 12-wk. exercise intervention for depressive symptoms in a group of adults with intellectual disabilities was conducted. Participants were 16 men and 11 women, randomly assigned to an exercise group (n = 14) or to a control group (n = 13). The Zung Self-Rating Depression Scale adapted for people with intellectual disabilities was administered at baseline, after 6 wk. and at the end of the intervention. There were statistically significant reductions in scores for the exercise group compared with the control group. Results support the notion that exercise can improve well-being in people with intellectual disabilities.

Physical activity practice, body image and visual impairment: A comparison between Brazilian and Italian children and adolescents

The aim of this study was to analyze the physical activity and body image of children and adolescents with visual impairment (VI) in Brazil and Italy. For this, 41 children and adolescents with VI (19 Brazilian and 22 Italian) aged 10.22 ± 2.19 years old (18 girls and 23 boys) answered the Physical Activity Questionnaire for Children (PAQ-C), the Offer Self-Image Questionnaire (OSIQ), and an instrument with information about the disability, body weight and height. We analyzed the relationship between data from PAQ-C and OSIQ, as well as the gender, level of disability (blindness or low vision) and country using independent Mann-Whitney test. Body mass index (BMI) values were higher for Brazilian youths, with more than half of them classified as overweight and obese. Italian youths exhibited values of body image that were more positive and only 27% presented overweight or obesity. Blind children and adolescents were less active than those with low vision, but no differences were found between countries or genders. In Brazil, we detected significant correlations (p>0.05) between physical activity, body image and BMI, which more active youths presenting lower values of BMI and a better perception of body image. Physical activity seems to have a positive influence on body image and BMI for children and adolescents with VI, thus it should be encouraged especially for those with higher disability degrees.

Peer-victimization during physical education and enjoyment of physical activity.

This study examined the relations between peer-victimization during sport practice and physical activity enjoyment. 395 students (219 boys, 176 girls) from a middle school, ages 12 to 13 years (M = 12.2), were surveyed. Few correlations between peer-victimization during sport practice and physical activity enjoyment variables were negative. Linear regression analysis was also conducted, highlighting a subtle influence of peer-victimization during practice of sports on enjoyment of physical activity. Peer-victimization during practice of sports seems to be a poor predictor of low enjoyment of physical activity.

Formação de professores para a educação especial: uma discussão sobre os modelos brasileiro e italiano

As public policies advance in the direction of mass producing inclusion of special educational needs students in regular schools, discussions have emerged about changes that are required in teacher preparation to meet this new demand. The aim of this study was to discuss Brazilian and Italian models of teacher preparation for those working in special education. To this end, we conducted a documentary study, analyzing legal texts related to the topic from both countries. Italy was the first country in Europe to promote the end of special schools and the inclusion of all students with disabilities in regular schools. Furthermore, in this country there are clear government guidelines regarding teacher preparation to work with students with special educational needs. On the other hand in Brazil, despite the great advances regarding public policies that support teacher preparation, specific parameters on the minimum content necessary for providing teachers with the subsidies they need to promote quality inclusion are still lacking.

A contribution to the validation of the Wii Balance Board for the assessment of standing balance

Abstract Valid and reliable accessible measures of balance are required in a health-related fitness test battery, both in the general population and in groups with special needs. For this purpose, the capability of the Wii Balance Board (WBB) in evaluating standing balance was analysed and compared with a laboratory-graded force platform (FP). A 30-s double limb standing test with open and closed eyes was performed by 28 individuals (12 male and 16 female, mean age = 23.8, SD = ±2.7 years). A simple method of acquisition of the centre of pressure (CoP) over time was applied to compare WBB and FP simultaneously on the same signal. User-defined software was developed to obtain the CoP from WBB over time and the resulting related measures and graphical representations. The comparison of measures, such as sway path and maximum oscillations along the anterior–posterior and medial–lateral direction, obtained with the FP and the WBB shows that the latter, in conjunction with the user-defined developed software, can be appropriate, considering prescribed limits, and an easy-to-use tool for evaluating standing balance.

Physical activity practice among children and adolescents with visual impairment – influence of parental support and perceived barriers

Abstract Purpose: To analyze the practice of physical activity among children and adolescents with visual impairments (VI), regarding the possible influence of parental support and perceived barriers. Methods: Twenty-two young people with VIs (10 + 2.74 years old) and one of each of their parents were evaluated. They responded to the Physical Activity Questionnaire for Older Children (PAQ-C), Baecke Questionnaire, the Parental Support Scale and a questionnaire about perceived barriers to physical activity. The independent samples t-test, pearson correlation test and chi-square test were performed. Results: Blind young people showed lower physical activity levels. There were significant correlations both between parents’ physical activity and the support offered to children and between the PAQ-C results and the importance given by young people to physical activity, but only for those aged between 8 and 10 years old. The main perceived barriers were lack of security, motivation, professional training and information about available physical activity programs. Conclusion: The influence of parental support seems to be an important factor in the adoption of a physically active lifestyle for young people with VI. Parents and children should have more information about the benefits and opportunities of physical activity. Implications for Rehabilitation Young people with visual impairment should be encouraged by parents to practice physical activity. More information should be provided on the benefits of physical activity to both parents and children. Professional training should be available to help support this group become more active.
