Efeitos da prática de exercício de dupla tarefa em idosos com Doença de Alzheimer: revisão sistemática / Effects of dual-task exercises in elderly with alzheimer´s disease: a systemic review

O presente estudo objetivou revisar de forma sistemática a literatura atual para sumarizar o efeito de intervenções com dupla tarefa sobre sintomas da Doença de Alzheimer. Trata-se de uma revisão sistemática da literatura. Foram utilizadas as bases de dados PubMed, Scielo e Lilacs. Incluíram-se estudos em idosos com Doença de Alzheimer, em tratamento por meio da dupla tarefa. Os quatro estudos incluídos mostraram que as intervenções duraram de 04 a 12 meses, com frequência semanal de duas a três sessões de no mínimo 60 minutos. O tamanho da amostra variou de 10 a 210 idosos. Um dos estudos apresentou a dupla tarefa com enfoque no exercício funcional. Outros dois apresentaram a dupla tarefa junto de exercícios aeróbios, força, resistência, equilíbrio e coordenação motora. Por fim, o quarto grupo utilizou apenas os exercícios de dupla tarefa. Os estudos têm comprovado que o exercício de dupla tarefa pode amenizar e controlar as perdas motoras e cognitivas ocasionadas por esta doença.

A systemic review of current literature is undertaken to summarize the effects of dual-task intervention on the symptoms of Alzheimer´s Disease through databases PubMed, Scielo and Lilacs. Studies with elderly with Alzheiomer´s Disease treated by the dual-task exercises were also used. The four studies showed that interventions lasted between 4 and 12 months, with weekly frequency of two or three 60-min sessions. Sample greatness varied between 10 and 210 elderly people. One of the studies showed the dual task focused on functional exercise and the other two demonstrated the dual task exercise with aerobic, strength, resistance, equilibrium and motor coordination exercises. The fourth group used the dual task exercise alone. Studies have proved that the dual-task exercise may lessen and control motor and cognitive losses caused by the disease.

Factors associated with body image dissatisfaction of weight training practitioners

Abstract AIMS This study aimed at investigating the socio-demographic and health-related variables associated with body image dissatisfaction. METHODS This is a cross-sectional study. 894 (34.04±13.62 years old) weight training practitioners from a medium-large city in the south of Brazil participated in this study. A socio-demographic questionnaire was used along with the Body Shape Questionnaire. The Chi-squared Test and the Binary Logistic Regression (p<0.05) were used to analyze the data. RESULTS Female subjects who have been practicing weight training for two to five years are more likely to be dissatisfied with their bodies (OR=4.305 [95% CI=2.984-6.213; OR=1.773 [95% CI=1.086-2.895], p<0,05, respectively). CONCLUSION There is one group of individuals who are less likely to experience body weight satisfaction. This group of people has three characteristics: 1, 2, and 3.
