Resistance Training and Diet in Patients with Chronic Renal Failure Clinical Trials Info presented on Clinical Trials Search isn't intended to be a substitute for qualified medical advice, visits or professional assistance by using a real mD. We are not docs. Always confer with your physician about Resistance Training and Diet in Patients with Chronic Renal Failure conditions. Clinical Trials Search.org is a website committed to listing clinical research studies in human subjects. Resistance Training and Diet in Patients with Chronic Renal Failure Clinical research trials and Resistance Training and Diet in Patients with Chronic Renal Failure health trials occur in many of cities throughout the US. A clinical trial or clinical study is a research project with human volunteer subjects. Clinical drug trials and pharmaceutical clinical trials generally evaluate the effectivity of new does drugs. The intent of the studies / undertakings is to resolve particular human health questions. Clinical trials are a popular way for physicians, government agencies, and private sector companies to detect remedies for all sorts of conditions, including Resistance Training and Diet in Patients with Chronic Renal Failure. Resistance Training and Diet in Patients with Chronic Renal Failure Clinical Trials and other clinical trials permit volunteers to obtain healthcare treatment alternatives before they are available to the masses. Most times the participants undergo professional assistance for without cost, and occasionally they are compensated for their time. Occasionally there is a cost for a Resistance Training and Diet in Patients with Chronic Renal Failure clinical trial. Test subjects typically receive the most expert healthcare available for their Resistance Training and Diet in Patients with Chronic Renal Failure condition. Dangers are a reality, however, and may include more or frequent mD visits, healthcare dangers (perhaps life-endangering), and/or the treatment being ineffectual. Trials are federally regulated with rigid guidelines to protect clinical trials patients.

Resistance Training and Diet in Patients with Chronic Renal Failure
For Condition: Kidney Failure, Chronic
Status: Recruiting
Sponsor(s): Department of Veterans Affairs Medical Research Service ,
Synopsis: This study will examine the effects of long-term adherence to a low protein diet (LPD) of 0.6 g/kg-1/d-1 with and without progressive resistance exercise training in patients with impaired renal function on body composition, renal function (glomerular filtration rate), nitrogen balance, muscle strength and size, and functional capacity. The hypothesis is that adherence to a LPD will result in a reduction in skeletal muscle mass and reduced strength and functional capacity while those patients who adhere to the LPD and exercise will demonstrate a similar preservation of renal function but will have greater fat free mass, muscle mass and strength. The intervention trial will last 18 months in which patients with moderate renal failure will be randomly assigned to one of 4 interventions: standard care, standard care + exercise, LPD, and LPD with exercise. In this way the independent and combined effects of diet and exercise on the progression of renal disease and body composition will be monitored. This study will have important implications for the treatment of patients with chronic renal failure. New strategies of combining exercise with recommendations of a low protein diet may slow the progression of renal disease and improve strength and functional capacity in these at-risk patients.
Details: Management of dietary protein intake of the CRF patient represents a critical balance between providing adequate protein to meet nutritional requirements, and limiting protein intake in the hope of slowing or abating the progression of CRF. A number of studies have demonstrated that reduced dietary protein intake can slow the progression of chronic renal failure. Finding effective ways to increase nitrogen retention and decrease urinary nitrogen excretion may help CRF patients maintain a more positive nitrogen balance and lessen the nitrogen load on the kidneys for a given dietary protein intake. Our laboratory has demonstrated that in older men and women, the consequence of adherence to a low protein diet is an accommodation that results in decreased muscle mass, strength,and compromised immune function. We have also demonstrated that when healthy, free living older men and women consume a weight maintenance diet providing the RDA for protein of 0.8 g/kg-1/day-1 for 15 weeks they lose skeletal muscle mass. These data clearly indicate that elderly people have an increased need for dietary protein (compared to young people). Data has also demonstrated that progressive resistance exercise improves nitrogen balance in older healthy individuals as well as in patients with mild to moderate chronic renal failure.
