Effect of three months of periodized hydrogymnastics exercise program on urinary concentration of deoxypyridinoline in older women

ABSTRACT Objective To determine the effect of three months of periodized hydrogymnastics exercise program on urinary concentration of deoxypyridinoline in older women. Subjects and methods Twenty-six subjects were randomly assigned in two, intervention group (n = 16) and control group (n = 10). The intervention group followed 12-week of periodized hydrogymnastics training program five times a week, 50 minutes of water exercise with work heart rate reserve of 40-50% (1-6thweek) increasing the load to 50-60% (7-12th week); the control group was not involved in exercise and remained sedentary. The urinary concentration of deoxypyridinoline was evaluated by high resolution liquid chromatography using the reactive immulite pyrilinks-D siemens medical solutions, pretest at the baseline and at the end post-test of the 12-week of water-exercise. As statistical analyses mixed 2 x 2 ANOVA was used, also percentage changes (Δ %) was calculated. Results The results did not show significant improvement (p < 0.05) comparing the interaction intergroup and the measurements of urinary concentration of deoxypyridinoline (p = 0.504), percentage change (Δ %) showed positive improvements in the experimental group of -13.7 (nM/mMcreatine) in comparison with -7.1 (nM/mMcreatine) from the control group. Conclusion The present study involves periodization increasing the load heart rate reserve of hydrogymnastics exercise in order to produce grater adaptations, but the results showed than is not possible to infer that hydrogymnastics is effective in increase urinary concentration of deoxypyridinoline in older women, will be appropriated in the future more studies to better clarify the possibilities of improvements between hydrogymnastics and urinary concentration of deoxypyridinoline.

Nível de atividade física para prevenção do excesso de gordura visceral em mulheres pós-menopáusicas: quanto é necessário? / Level of physical activity in the prevention of excess visceral fat in postmenopausal women: how much is needed?

OBJETIVO: Analisar a quantidade de atividade física (kcal/semana) necessária à prevenção do excesso de gordura visceral em mulheres pós-menopáusicas. SUJEITOS E MÉTODOS: A amostra incluiu 239 mulheres com uma idade média de 57,2 anos. A área de gordura visceral (AGV) foi medida por bioimpedância octopolar e a atividade física, com a versão longa do IPAQ. Foram construídas curvas Receiver Operating Characteristic (ROC) e considerado um intervalo de confiança de 95%. RESULTADOS: As áreas sob a curva ROC para a atividade física moderada e a caminhada revelaram-se significativas. O dispêndio semanal de 1.601 kcal na caminhada ou de 2.283 kcal de atividade física moderada foi identificado como bons valores de corte para prevenir o excesso de AGV. CONCLUSÃO: A prática da atividade física de intensidade leve a moderada, com um gasto calórico entre 1.601 e 2.283 kcal/semana, previne o excesso de adiposidade central em mulheres pós-menopáusicas.

OBJECTIVE: To analyze the level of physical activity (kcal/week) needed to prevent excess visceral fat in postmenopausal women. SUBJECTS AND METHODS: The sample included 239 women with a mean age of 57.2 years. Visceral fat area (VFA) was measured by octopolar bioelectrical impedance, and physical activity, by the long version IPAQ. ROC Curves (Receiver Operating Characteristic) were drawn, and a 95% confidence interval was used. RESULTS: The areas under the ROC curve for moderate physical activity and walk proved to be significant. Weekly expenditure of 1,601 kcal in walking, or 2,283 kcal in moderate physical activity were identified as good cutoff values to prevent excess VFA. CONCLUSION: Mild to moderate physical activity, with a caloric expenditure between 1,601 and 2,283 kcal/week, prevents excess central adiposity in postmenopausal women.

Menopausa em forma: Programa de Promoção do Exercício e da Saúde em Mulheres Pós-Menopáusicas / Menopause in form: Programe of Promotion of the Exercise and the Health in Women Pos-Menopause

O menopausa em forma é um programa de promoção do exercício e da saúde de mulheres pós-menopáusicas, promovido pela Universidade de Trás-os-Montes e Alto Douro (Vila Real, Portugal) e que pretende demonstrar a eficácia de um programa de exercício na melhoria da saúde cardiovascular, na aptidão física e funcional, no risco de queda e na sintomatologia do climatério. Trata-se de um estudo randomizado, envolvendo 300 mulheres com amnorreia permanente e incluindo um número vasto de avaliações, procurando-se desenvolver, validar e clarificar alguma informação específica nesta população, de acordo com as necessidades identificadas na literatura. O programa de exercício físico envolve 3 componentes – step, musculação e flexibilidade/controlo postural – sendo apresentadas as linhas orientadoras do mesmo, em função dos objectivos definidos para a investigação.
