O estudo teve como objetivo avaliar o efeito de um programa de exercício físico nos níveis de atividade física (AF) habitual em pacientes hemodialisados. A amostra foi composta por 24 pacientes hemodialisados, dos quais 45.8% do sexo feminino, com uma idade média de 75.1 ± 11.8 anos, que participaram num programa de exercício aeróbio intradialítico, 3 vezes por semana, ao longo de 8 semanas. A carga de treino foi individualizada, com aumento progressivo de acordo com a autoperceção de esforço. Foram utilizados acelerómetros para a avaliação da AF durante uma semana completa, tanto antes como depois da aplicação do programa. Os resultados indicaram que a AF predominantemente realizada, em ambos os momentos de avaliação, foi de intensidade leve. Por outro lado, a AF moderada e vigorosa juntas perfizeram menos de 1% do total de AF realizada. O tempo despendido em AF leve aumentou significativamente entre o pré e o pós-teste (p= 0.03), enquanto o tempo despendido em atividades sedentárias, AF moderada e AF vigorosa não se alterou de forma significativa. Em conclusão, os níveis de AF leve aumentaram de forma significativa entre o pré e o pós-teste, não se registando mudanças significativas no tempo de sedentarismo, na AF moderada e na AF vigorosa.
The purpose of this study was to evaluate the effectiveness of an exercise program on changes in phys- ical activity (PA) levels of hemodialysis patients. The sample consisted of 24 hemodialysis patients, 45.8% of female subjects, with an average age of 75.1 ± 11.8 years, were subjected to an aerobic exer- cise program intradialytic 3 times per week over 8 weeks. The training load was individualized with progressive increase through the self-perception effort. Accelerometers were used for the evaluation of PA during a continuous week, before and after the implementation of the program. The results sug- gested that PA mainly performed in both moments of evaluation was light intensity, on the other hand, the moderate and vigorous PA together constituted less than 1% of total PA performed. The time spent in light PA increased significantly between the pre and post-test (p= 0.03), while the time spent in sedentary activities, moderate PA and vigorous PA did not change significantly. In conclusion, light PA significantly increased between the pre and post-test. There were not significant changes in sedentary time, in moderate and vigorous PA.
