Virtual and augmented reality technologies in Human Performance: a review

Introduction : Todays society is influenced by Information and Communication Technologies. Toys that were once built by hand have been reinterpreted and have become highly commercialized products. In this context, games using Augmented Reality (AR) and Virtual Reality (VR) technologies are present in the everyday lives of children, youth and adults. Objective : To investigate how Physical Education professionals in Brazil have been making use of AR and VR games to benefit their work. Materials and methods : We only included studies that addressed exercise or physical activity using AR or VR games. We searched the databases of Virtual Health Library (VHL) and Scientific Electronic Library Online (SciELO), using the words augmented reality, virtual reality, exergames, Wii and serious games. Results : Nineteen articles were included in the systematic review. The most frequently used device was the Nintendo(r) Wii, with over 25 different kinds of games. With regard to the subjects of the studies, four studies were conducted with healthy individuals (mean = 65.7), three with patients with Parkinsons disease (mean = 18.0), three with elderly women (mean = 7.7) and two with patients with stroke injury (mean = 6.0). Conclusion : Many physical therapists and occupational therapists use serious games with AR or VR technologies as another work tool, especially for rehabilitation practices. The fact that these technologies are also used in Physical Education classes in Brazil indicates that electronic games are available and can be a tool that can contribute to the widespread adoption of exercise as an enjoyable form of recreation.

Infection risk in gyms during physical exercise

This study aimed to analyze the risk of infection (influenza and tuberculosis) for individuals participating in physical exercise. This was achieved by assessment of carbon dioxide (CO2) concentrations, and examination of the physical characteristics of a number of gyms to determine whether there was a relationship to CO2 levels. This study was performed in three different gyms ventilated with either split system or central system air conditioners. The risk of airborne infection (percent of susceptible persons infected) was estimated for each gym using the Wells-Riley model. The risk of infection increased during periods of peak occupancy where the ventilation required by occupants was greater. In each gym, the highest risk of infection occurred during the evening where occupancy and CO2 levels were high. The infection risk for influenza was high in all situations due to the high quantum generation rate for this agent. This study suggests that inefficient ventilation in gyms is a significant problem, with high CO2 concentrations resulting in impaired air quality and high health risks to users, including increased risk of infections such as influenza and tuberculosis.

Autoestima, imagem corporal e depressão de adolescentes em diferentes estados nutricionais

OBJECTIVE To investigate self-esteem, body image and depression in adolescents under different nutritional conditions. The study included 418 adolescents (14-18 years old). METHODOLOGY Four questionnaires were administered: Characterization; Child Depression Inventory; Self-esteem Scale, and Body Image Questionnaire. The nutritional conditions were classified using the Body Mass Index (BMI). RESULTS Boys had a higher prevalence of overweight or obesity, a lower depression and body dissatisfaction rate, and higher self-esteem than girls (p<0.001). Depression was negatively related to self-esteem (p<0.01), which also had a negative association with body dissatisfaction (p<0.01). Even though adolescents with superior nutritional conditions were more dissatisfied (p<0.001), the BMI was related to body dissatisfaction only in girls (p<0.01). Regarding the relation between depression and body dissatisfaction, it was negative for boys (p<0.01), but positive for girls (p<0.01). CONCLUSION Overweight or obese adolescents have higher body dissatisfaction. Depression and self-esteem are related to body image, and not to BMI, demonstrating that the subjectivity of adolescents must be assessed. The differences identified between boys and girls for these relations must be further investigated.

Debates acadêmicos por videoconferência: uma solução com software livre

O objetivo deste estudo foi descrever o relato de uma experiencia utilizando recursos de videoconferencia com software livre para fins de defesa de mestrado em um programa de pos-graduacao. A solucao apresentada inclui um tablet, celular com câmera e sistema Android e os softwares freeware: Skype, DroidCam, PowerPoint OpenOffice Remote e LibreOffice Impress, alem de outros recursos necessarios a apresentacao propriamente dita (projetor multimidia, computador, som, microfone, alem de outros). O uso do software livre para a videoconferencia mostrou-se uma otima maneira de apoiar a formacao de bancas de defesa a distância permitindo a integracao no processo de formacao de estudantes.

Ansiedade associada a fatores sociodemográficos e clínicos de mulheres com síndrome da fibromialgia

JUSTIFICATIVA E OBJETIVOS: Caracterizar a ansiedade de mulheres com sindrome da fibromialgia e verificar a associacao dos niveis de ansiedade traco e estado com dor e sono nao restaurador. METODOS: Participaram do estudo 61 mulheres com diagnostico clinico de sindrome da fibromialgia, residentes na Grande Florianopolis. Foram usados, como instrumentos de pesquisa, o Questionario Sociodemografico e Clinico (QSDC) e o Inventario de Ansiedade Traco-Estado (IDATE). RESULTADOS: A media de idade das pacientes do estudo foi de 49 ± 9,2 anos. A dor generalizada predominou em 88,5% (n = 54) das participantes, assim como o sono nao restaurador estava presente em 54 mulheres (88,5%). No perfil de ansiedade estado, observou-se o nivel de ansiedade media em 57,4% das participantes (n = 35). Ja no perfil de ansiedade traco, o nivel de ansiedade media ocorreu em 85,2% das mulheres (n = 52). Houve correlacao significante entre o sono nao restaurador e ansiedade traco (p = 0,03). Nao houve correlacao entre as variaveis dor generalizada e ansiedade traco (p = 0,53), dor generalizada (p = 0,98) e sono nao restaurador (p = 0,10) e ansiedade estado. CONCLUSAO: Nesta populacao de mulheres com sindrome da fibromialgia, houve o predominio do nivel medio de ansiedade tanto para o estado quanto para o traco de ansiedade. Nao foi observada correlacao da dor com ansiedade traco nem estado, entretanto, foi observada uma correlacao entre mulheres com ansiedade traco e sono nao restaurador.
