Abstract
FUNDAMENTO: Na população geral, a prática regular de exercícios físicos se associa à melhora da capacidade funcional e à redução de eventos cardiovasculares. Já em portadores de doença renal crônica, uma população com significativo comprometimento da capacidade funcional e elevadas taxas de mortalidade cardiovascular, poucos estudos avaliam os efeitos da atividade física. OBJETIVO: Avaliar o efeito do treinamento aeróbico durante as sessões de hemodiálise, sobre a capacidade funcional e a pressão arterial de pacientes renais crônicos. MÉTODOS: Foram avaliados 14 pacientes portadores de doença renal crônica sob tratamento hemodialítico, antes e depois de 12 semanas de treinamento aeróbico realizado durante as sessões de hemodiálise. Os pacientes foram submetidos a monitorização ambulatorial da pressão arterial de 24 horas, teste de caminhada de 6 minutos e teste cardiopulmonar de exercício antes e depois do período de treinamento. RESULTADOS: Após o treinamento, observou-se aumento significativo da distância percorrida no teste de caminhada de 6 minutos de 509 ± 91,9 m para 555 ± 105,8 m, além de redução significativa da pressão arterial sistólica de 151 ± 18,4 mmHg para 143 ± 14,7 mmHg, da pressão arterial diastólica de 94 ± 10,5 mmHg para 91 ± 9,6 mmHg e da pressão arterial média de 114 ± 13,0 mmHg para 109 ± 11,4 mmHg. CONCLUSÃO: O treinamento aeróbico realizado durante as sessões de hemodiálise contribuiu para a melhora da capacidade funcional e para o controle da hipertensão arterial dos pacientes portadores de doença renal crônica.
BACKGROUND: In the general population, regular practice of physical exercises is associated with improved physical capacity and reduction of cardiovascular events. Concerning patients with chronic kidney disease, a population with significant impairment of physical capacity and high rates of cardiovascular mortality, few studies have evaluated the effects of physical activity. OBJECTIVE: To evaluate the effect of aerobic exercise during hemodialysis on the physical capacity and blood pressure of patients with chronic renal failure. METHODS: We evaluated 14 patients with chronic kidney disease under hemodialysis, before and after 12 weeks of aerobic exercise performed during hemodialysis sessions. Patients underwent ambulatory blood pressure monitoring for 24 hours, 6-minute walk test and cardiopulmonary exercise test before and after the exercise period. RESULTS: After the exercise, there was a significant increase in the distance walked during the 6-minute walk test from 509 ± 91.9 m to 555 ± 105.8 m, and a significant reduction in systolic blood pressure of 151 ± 18.4 mmHg to 143 ± 14.7 mmHg, diastolic blood pressure of 94 ± 10.5 mmHg to 91 ± 9.6 mmHg and average arterial pressure from 114 ± 13.0 mmHg to 109 ± 11.4 mmHg. CONCLUSION: Aerobic exercise conducted during hemodialysis sessions contributed to the improvement of physical capacity and control of hypertension in patients with chronic kidney disease.
