Resumo
O envelhecimento promove mudanças nos diversos sistemas, especialmente músculo-esquelético e cardiopulmonar. Exercícios físicos regulares melhoram o condicionamento cardiorrespiratório, modificam as dimensões corporais e neuromusculares, amenizando o impacto do envelhecimento na capacidade funcional. Com o objetivo de analisar os efeitos do exercício físico sobre indicadores pulmonares e antropométricos em idosas, dois estudos foram realizados. O Estudo 1 observou os efeitos da especificidade do exercício sobre indicadores antropométricos e pulmonares em idosas. Quarenta mulheres acima de 60 anos, compuseram quatro grupos (Sedentárias, Hidroginástica, Musculação e Dança). O Estudo 2 verificou os efeitos de um Programa de Exercícios Generalizados (PEG) em indicadores antropométricos e pulmonares em mulheres sedentárias entre 60 a 78 anos. Participaram do estudo trinta e duas mulheres, que compuseram dois grupos: Controle (n=14) e Intervenção (n=18). Para ambos os estudos, foram analisadas as variáveis antropométricas (índice de massa corpórea, circunferência muscular do braço e panturrilha, dobra cutânea tricipital e relação cintura/quadril); nível de atividade física (Questionário de Baecke) e função pulmonar [pressões respiratórias máximas, mobilidade torácica e espirometria (capacidade vital forçada - CVF, volume expiratório forçado no primeiro segundo - VEF1, relação VEF1/CVF, fluxo médio expiratório forçado - FEF25-75% e pico de fluxo expiratório)]. No Estudo 2, as participantes foram reavaliadas após 4 meses de intervenção. No Estudo 1, para o nível de atividade física, houve diferenças quanto à especificidade do exercício (p ≤ 0,001) entre Sedentárias e demais...
Aging promotes changes in many systems, especially for musculoskeletal and cardiopulmonary functions. Regular physical exercise improves cardiorespiratory fitness and modifies body and neuromuscular dimensions, all while softening the impact of aging on functional capacity. To analyze the effects of physical exercise on pulmonary and anthropometric measurements in older women, two studies were conducted. Study 1 observed the effects of specific exercises on anthropometric and lung measurements in elderly women. Forty women over 60 years old in four groups (Sedentary, Hidroginastics, Bodybuilding and Dance) were studied. Study 2 examined the effects of a generalized exercise program (GEP) on anthropometric and lung measurements in sedentary women between 60-78 years. Thirty-two women, formed two groups: Control (n = 14) and Intervention (n = 18). For both studies, we analyzed anthropometric variables (body mass index, arm and calf muscle circumference, triceps skinfold thickness, and waist/hip ratio), level of physical activity (Baecke questionaire), pulmonary function [maximal respiratory pressures, thoracic mobility and spirometry (forced vital capacity - FVC, forced expiratory volume in one second - FEV1, FEV1/FVC, forced expiratory flow medium - FEF25-75% and peak expiratory flow)]. Participants were reassessed after four months of intervention. Study 1 participants were assessed according to level of physical activity, there were differences in the specificity of exercise (p ≤ 0,001) between sedentary and other groups as well as between hidroginastics and the two groups (dance and bodybuilding). In axillary thoracic mobility, there were differences between bodybuilding and the sedentary and dance groups (p ≤ 0,05). Differences also occurred for xiphoid thoracic...
