contribuindo para o aumento da gordura abdominal, e consequentes complicações metabólicas. O exercício físico permite
quebrar este ciclo através da estimulação da lipólise e da utilização de ácidos gordos. Objetivo: Verificar os efeitos de um
programa de exercícios no domicílio, em indivíduos com doença arterial coronária, na composição corporal, gordura
abdominal, perfil lipídico, glicose, e nível de atividade física. Métodos: Estudo experimental composto por 20 indivíduos,
aleatorizados grupo experimental (GE) e grupo de controlo (GC), ambos com 10, tendo o GE sido sujeito ao programa
durante 8 semanas. Realizou-se uma avaliação inicial e final, através da bioimpedância, Tomografia Computorizada (TC)
abdominal, perimetria, adipometria, análises sanguíneas e acelerómetro. Resultados: Numa análise intergrupal, verificouse
uma diminuição da percentagem (%) de gordura total (GT) calculado pela adipometria (p<0.01), na prega supra-ilíaca
(p=0.005), na prega abdominal horizontal (p=0.001) e vertical (p=0.003) no GE, e da % de tempo em atividades moderadas
no GC (p=0.035). Após 8 semanas o GE diminuiu a %GT (p=0.008); a massa gorda (MG) (p=0.002); perímetro abaixo da
última costela (p=0.037) e acima das cristas-ilíacas (p=0.021); %GT calculado (p=0.002); pregas supra-ilíaca (p=0.008),
abdominal horizontal (p=0.002) e vertical (p=0.033); TC abdominal subcutâneo (p=0.031) e %de tempo em atividades
vigorosas (p=0.031). O GC diminuiu a %GT (p=0.002) e MG (p=0.008); aumentou o perímetro ao nível dos grandes
trocânteres (p=0.008), diminuiu o rácio cintura/anca (p=0.002), e a %de tempo em atividades moderadas (p=0.031) e
vigorosas (p=0.008). Parece existir uma tendência no GE para diminuição do rácio cintura/anca, c-LDL, triglicerídeos e
aumento do nível de atividade moderado. Conclusão: O programa de exercícios no domicílio demonstrou uma diminuição
da gordura abdominal, alteração da composição corporal, e parece promover uma melhoria no perfil lipídico e no aumento
do nível de atividade física moderado.
increased abdominal fat, and consequently metabolic complications. The exercise can break this cycle by stimulating lipolysis and use of fatty acids. Objective: Verify the effects of an home based exercise program, in individuals with coronary artery disease, body composition, abdominal fat, lipid profile, glucose, and physical activity level. Methods: Experimental study consisted of 20 individuals randomized in experimental group (EG) and control group (CG), both with 10, EG having been subjected to the program for 8 weeks. We performed an initial and end evaluation by bioimpedance, Computed Tomography (CT) abdominal, circumference, skinfold thickness, blood tests and accelerometer. Results: In intergroup analysis, there was a decrease in the percentage (%) of total fat calculated by adipometria (p<0.01), the suprailiac skinfold (p=0.005), abdominal horizontal fold (p=0.001) and vertical (p=0.003) in GE, and % time in moderate activities in the GC (p = 0.035).After 8 weeks the EG decreased statistically % total fat (p=0.008), fat mass (p=0.002); perimeter below the last rib (p=0.037) and above the iliac crests, (p=0.021); % total fat calculated (p=0.002); suprailliac fold (p=0.008), abdominal horizontal fold (p=0.002) and vertical (p=0.033); subcutaneous abdominal CT (p=0.031) and % of time in vigorous activities (p = 0.031). The CG decreased significantly % of total fat (p=0.002) and the fat mass (p=0.008); significantly increased at the perimeter of the greater trochanters (p=0.008) and decreased the ratio waist/hip (p=0.002). Still, there seems to be a tendency to EG decrease in ratio waist/hip, LDL-c, triglycerides and increased level of moderate activity. Conclusion: The home based exercise program showed a decrease in abdominal fat, a change in body composition, and seems to promote an improvement in lipid profile and increased level of moderate physical activity.
