Summary

When patients progress to the final stage of chronic kidney disease (CKD) and require hemodialysis treatment, they typically have lost so much muscle function that they are no longer physically independent. However, due to disease- and hemodialysis-related muscle catabolism, dietary protein and exercise interventions are only capable to attenuate the decline in physical function of patients on hemodialysis treatment. Therefore, lifestyle interventions to increase muscle function should be implemented before hemodialysis is required. However, it is still a matter of debate whether muscle protein synthesis rates of patients with advanced CKD can be increased with a patient-tailored dietary protein and exercise intervention.Therefore, the current study will assess MPS rates during habitual lifestyle and during an interventional program including dietary protein and exercise in patients with advanced CKD. In addition, we will compare MPS rates during free-living conditions between patients with advanced CKD and healthy controls.

Whey protein

Throughout 1 week (either in week 1 or 2), all participants will perform a 1-week resistance type exercise-training program, consisting of two different exercises. Leg press and leg extension exercise will be performed on regular weightlifting machines (Technogym, Rotterdam) at 3 days during the 1-week period (e.g. Monday-Wednesday-Friday). During the resistance exercise training protocol, participants will continue their habitual diet as usual. However, patients with CKD will be provided with a protein supplement following the exercise sessions.
