ABSTRACT
Objective: Sustained practice of Yoga leads to self-awareness, physical strength and high sense of energy. Yoga stimulates antioxidant levels in the body and reduces likelihood of dental disorders. No research has been undertaken connecting perception on yoga and oral health behaviors. The present study is an attempt to develop a psychometric scale entitled Perceived Benefits on Yoga Scale (PBYS) to measure individuals' perception on Yoga in relation to oral health behaviors. Material and methods: The psychometric tool was developed based on the concepts of Health Benefit Model (HBM). Among the four components of the model, the present study considered "perceived benefits" component. A total of 206 individuals participated in the study. To analyze the scale theoretically, face and content validity were assessed. Reliability of the scale was tested using Cronbach's alpha and Spearman-Brown coefficient. Using exploratory and confirmatory factor analysis, construct validity was tested. Cronbach alpha and Spearman- Brown coefficient were applied to test the reliability of scale. Results: There were six items in the final scale, with a Spearman- Brown coefficient of 0.92 and Cronbach's alpha of 0.91. Statistically significant (p < 0.001) positive correlation was found between POBYS scores and Yoga Self-Efficacy Scale (YSES). Validity of scale is within accepted range as indicated by Goodness of Fit indices. Conclusion: POBYS is a reliable and valid measure of perception on yoga outcomes with specific reference to oral health behavior. (AU)
Objetivo: A prática continua de Yoga leva ao autoconhecimento, força física e a sensação de energia elevada. O yoga estimula os níveis de antioxidantes no corpo e reduz a probabilidade de desordens dentais. Nenhuma pesquisa foi realizada conectando a percepção sobre o yoga e os comportamentos da saúde bucal. O presente estudo é uma tentativa de desenvolver uma escala psicométrica intitulada Escala de Benefícios Percebidos no Yoga (PBYS) para medir a percepção dos indivíduos sobre o Yoga em relação aos comportamentos da saúde bucal. Material e Métodos: A ferramenta psicométrica foi desenvolvida com base nos conceitos do Modelo de Benefícios à Saúde (HBM). Dentre os quatro componentes do modelo, o presente estudo considerou o componente "benefícios percebidos". Participaram do estudo 206 indivíduos. Para analisar teoricamente a escala, foram avaliadas a validade de face e de conteúdo. A confiabilidade da escala foi testada usando o alfa de Cronbach e o coeficiente de Spearman-Brown. Usando análise fatorial exploratória e confirmatória, a validade do construto foi testada. O alfa de Cronbach e o coeficiente de Spearman-Brown foram aplicados para testar a confiabilidade da escala. Resultados: Havia seis itens na escala final, com coeficiente de Spearman-Brown de 0,92 e alfa de Cronbach de 0,91. Estatisticamente significativo (p <0,001) foi encontrada correlação positiva entre os escores do PBYS e a Escala de Autoeficácia do Yoga (YSES). A validade da escala está dentro da faixa de aceitabilidade conforme indicado pelos índices de Goodness of Fit. Conclusão: PBYS é uma medida confiável e válida de percepção sobre os resultados do yoga com referência específica ao comportamento de saúde bucal. (AU)

The present study was conducted to assess the immediate effect of high-frequency yoga breathing on muscle strength and motor speed. Bilateral handgrip strength, leg and back strength, finger tapping and arm tapping speed were assessed in fifty male participants (group mean age±SD, 26.9±6.2 years) before and after (a) high frequency yoga breathing for 15 minutes and (b) breath awareness for the same duration. Sessions (a) and (b) were on two different days but at the same time of the day. The schedule was alternated for different participants. There was a significant increase (P<0.05) in right hand grip strength after high frequency yoga breathing. Both finger and arm tapping improved after both practices. The results suggest a role for high frequency yoga breathing in improving the hand grip strength as an immediate effect.
ABSTRACT
State anxiety, somatization of stress, quality of life, self-rated quality of sleep, and discomfort due to over-breathing which occurs when stressed were studied. Out of a total of 140 participants, seventy participants self-selected to be in a yoga group for stress relief (group mean age±SD, 33.0±6.5 years; 37 males). Seventy age and gender matched participants were in a control group. State anxiety, somatization of stress, quality of life, discomfort and self-rated quality of sleep were assessed using the State-Trait Anxiety Inventory, Symptom Checklist-90-R, SF-12, Nijmegen Discomfort Evaluation Scale and a Sleep Rating Questionnaire respectively. Assessments were made at the beginning and end of the week. Repeated measures ANOVAs with Bonferroni adjusted post-hoc analyses showed a significant decrease in state anxiety (P<0.001), somatization of stress (P<0.01), improved health-related quality of life (P<0.01), self-rated quality of sleep (P<0.01), and decrease in discomfort due to over-breathing (P<0.001). No changes (except decreased discomfort due to over-breathing; P<0.01) occurred in the control group. This study suggests that a brief yoga program may be beneficial in decreasing anxiety, somatization of stress and discomfort, improving health-related quality of life and self-rated sleep quality.
