BACKGROUND: For children and adolescents with chronic end stage renal disease (ESRD), less specific information on regulation of endurance training especially during dialysis are available. The aim of this pilot study was to review control parameters of a subjectively-measured aerobic endurance training in children and adolescents during hemodialysis.
METHODS: The study included 14 children and adolescent, five children, aged 16.6±1.34 years completed the training program. The average height of the subjects was 153.3±14.29 cm and a body weight of 46.4±9.48 kg. The trial was a single-group trial with pre-/post-test design. The intervention consisted of a 12-week subjectively-controlled training on spinning bikes with two to three sessions per week. Based on a cardiopulmonary exercise testing before dialysis, the examination of exercise capacity was reviewed. Based on the findings several recommendations can be determined for the training during dialysis.
RESULTS: In addition to the subjectively-controlled training program, 20 to 40 minutes of an endurance-oriented exercise program during each dialysis is suitable. Hence, training at the ventilatory threshold implies a stable blood pressure value. A drop in blood pressure needs to be accompanied with a wattage reduction.
CONCLUSIONS: The results of the present study revealed, based on the low level of endurance capacity and the heterogeneity of the ESRD patients, a subjectively-controlled training seems to be appropriate. The most performance limiting factor is the arterial blood pressure.
