Resumo
Objetivo: Verificar o comportamento da prática habitual de atividade física, ingestão alimentar, perfil metabólico e composição corporal total e segmentar após seis e 12 meses do término de dois programas de treinamento, um aeróbio e outro concorrente, em mulheres pós-menopausa. Métodos: Participaram do estudo mulheres com idade entre 50 a 70 anos, todas na pós-menopausa, da cidade de Presidente Prudente, SP, Brasil, randomizadas em três grupos: Treinamento Concorrente (aeróbio+força, TC, n=20), Treinamento Aeróbio (TA, n=20) e Grupo Controle (GC, n=20). As avaliações foram realizadas: pré, pós quatro meses de treinamento e após seis e 12 meses do término da intervenção, e retornaram para avaliação: TC (n=15), TA (n=8) e GC (n=8). A composição corporal foi estimada por meio do DEXA, e perfil metabólico (Colesterol total e frações LDL-c e HDL-c, Triacilglicerol e Glicose) foi analisado. Para avaliação da prática habitual de atividade física (AF) foi utilizado acelerômetros triaxial e a ingestão alimentar foi avaliada por meio do registro alimentar de 24 h. Todas as análises estatísticas foram realizadas utilizando o programa BioEstat, versão 5.0 e a significância estabelecida em 5%. Resultados: Houve redução significante da prática habitual de atividade física leve para o grupo controle pós-intervenção e aumento da ingestão lipídica após seis meses do término dos programas de TA e TC. Houve aumento significante de HDL-c (Pré=54,4±16,1 vs Pós=61,0±17,7 vs Pós 6 meses= 54,9±16,4 vs Pós 12 meses= 56,3±16,1 mg/dl, p<0,05) e massa corporal magra total (Pré=34,4±4,1 vs Pós=35,3±4,3 vs Pós 6 meses= 34,8±4,6 vs Pós 12 meses= 35,3±4,1 kg, p<0,05) e de perna (Pré=11,2 ±1,6 vs Pós=11,5±1,6 vs Pós 6 meses= 11,2±1,6 vs Pós 12 meses= 11,4±1,5 kg; p<0,05) pós-treinamento para o grupo TC, no entanto, a massa magra de perna retornou aos valores iniciais após seis meses do término da intervenção. Conclusão: Nossos resultados salientam a importância da prática regular do exercício físico para a melhora da prática habitual de AF, ingestão alimentar, perfil metabólico e massa corporal magra de mulheres pós-menopausa.
Purpose: To verify the daily habit of physical activity, dietary intake, metabolic profile and total and appendicular body composition at six and 12 months after the end of two training programs, an aerobic and another concurrent training program in postmenopausal women. Methods: The participants of the study were postmenopausal women, aged between 50 to 70 years old from Presidente Prudente, SP, Brazil, randomized into three groups: Concurrent training group (aerobic plus strength, CT, n = 20), Aerobic training group (AT, n = 20) and Control group (CG, n = 20). The assessment was performed: pre, post four months of training and after six and 12 months after program end, and the subjects came back for assessment: CT (n=15), AT (n=8) and CG (n=8). The body composition was estimated by DXA, and the metabolic profile (total cholesterol, LDL-c and HDL-c, triacylglycerol and glucose) was evaluated. For the daily habit of physical activity (PA) assessment, triaxial accelerometers were used and dietary intake was assessed by 24-hour food record. All statistical analysis were performed using BioEstat software, version 5.0 and significance established at 5%. Results: There was a statistically significant reduction on the light physical activity level for CG, and increased lipid intake six months after program end for AT and CT. There was a significant increase in HDL-c (Pre=54.4±16.1 vs Post=61.0±17.7 vs Post 6 months= 54.9±16.4 vs Post 12 months= 56.3±16.1 mg/dl, p<0.05), total lean mass (Pre=34.4±4.1 vs Post=35.3±4.3 vs Post 6 months= 34.8±4.6 vs Post 12 months= 35.3±4.1 kg, p<0.05) and leg lean mass (Pre=11.2 ±1.6 vs Post=11.5±1.6 vs Post 6 months= 11.2±1.6 vs Post 12 meses= 11.4±1.5 kg; p<0.05) for CT group, but leg lean mass returned to baseline values after six months following the end of the program. Conclusion: Our results highlight the importance of a regular exercise program to improve PA level, dietary intake, metabolic profile and lean mass in postmenopausal women.
