Evaluating the impact of specialized cardio-cycling exercises on the clinical status of chronic dialysis patients, objectified by examining laboratory indicators of mineral and bone disorders

Chronic kidney disease leads to serious complications related to the disability of patients. This gives reason to discuss and work to improve their quality of life. In recent years, attention has been focused on physical activity and renal rehabilitation, in order to overcome movement disorders.In the Nephrology Clinic at St. Marina University Hospital, Varna, the influence of cardio-cycling exercises on the clinical status of hemodialysis (HD) patients was assessed, objectified by examining laboratory indicators, such as serum phosphorus, serum calcium, iPTH, and CRP.We studied a total of 69 patients-divided into two groups: control (n = 32) and experimental (n = 37), conducting cardio-cycling exercises. The values of serum phosphorus, calcium, and CRP were examined in both groups at the beginning, at the 3rd and at the 6th month, and the values of iPTH—at the beginning and at the 6th month.The analyzed data showed that in HD patients performing intradialytic exercises, bone mineral indices improve in terms of Ca and P, but not those for PTH. The highest correlation was found for serum Ca.In patients with CKD on HD treatment, in whom various techniques of renal rehabilitation were applied, good results were reported in the volume and cycling. The cooperation of patients is important. This requires convincing them of the positive effect of the test and its implementation in order to improve their tone and physical activity.
