Abstract
Background: chronic kidney disease (CKD) is a type of kidney disease in which there is gradual loss of kidney function over a period of months to years. Initially there are generally no symptoms; later, symptoms may include leg swelling, feeling tired, vomiting, loss of appetite, and confusion. Complications include an increased risk of heart disease, high blood pressure, bone disease, and anemia. In hemodialysis patients, special causes of variations are well known in association with dialysis-induced changes, hemoconcentration, subsequent hemodilution (albumin variation), interdialytic interval, vitamin D and calcium intake, PTH related disorders and bone resistance to PTH action. Blood calcium measurement is recommended in patients on HD. The Kidney Disease Improving Global Outcomes (KDIGO) foundation recommends the measurement of Ionized Ca levels if possible. Exercise encourage calcium absorption in bone. Like muscles bones respond to increase of blood flow and it is thought that the increased circulation prompted by exercise transports of vital nutrients and minerals such as calcium to bones.Purpose: The purpose of the study was to determine the effect of weight bearing exercise on ionized calcium status in hemodialysis patients.Subject and Methods: Thirty patients who diagnosed as CKD with age ranged from 30 to 60 years were selected randomly from Hemodialysis Unit of Ain Shams General Hospital .Only who agreed to be volunteers participated in this study and were randomized into two groups of equal number, 5 patients for each group, group (A) received weight bearing exercise through walking on treadmill for30mintes,3times/week for 12 successive weeks plus their medical care.group (B) control group not received any exercise just their medical care.,Parameters: Laboratory assessment(ionized calcium)before the initiation of the training program and after the completion of the study (after 12 weeks).Results: The results showed that there was a statistically significant increase in ionized calcium of group (A) with a percentage of improvement that reaches 67.64% Conclusion: It can be concluded that weight bearing exercise is very important for hemodialysis patients
