Because creatinine is a derivative of creatine phosphate, an energy source present in the skeletal muscles, serum creatinine levels are influenced by muscle mass. Elderly people with less muscle mass have low c
Muscle massMuscle performanceRenal transplant recipientsBackgroundMuscle mass, as determined from 24‐h urinary creatinine excretion rate (CER), is an independent predictor for mortality and graft failure in renal transplant recipients (RTR). It is currently unknown whether CER is comparable with ...

1 In normal active adults, major fluctuations in muscle mass are unusual, but when conditions such as disuse or disease are present, muscle mobilizes and degrades proteins to provide amino acid precursors for energy utilization and for mounting a response to the condition. A symphony of ...

Estimation of creatinine clearance requires knowledge of creatinine generation which can vary in different groups of patients. Since the main source of creatinine is muscle we used dual-energy X-ray absorptiometry to measure the mass of muscle in a cohort of adult men and women in Rochester, ...

The contractile ability of a muscle is expressed in terms of the muscle’s absolute strength, the ratio of a muscle’s mass to the area of its cross-section taken at the plane perpendicular to the fibers. Absolute strength is expressed in kilograms per centimeter squared (kg/cm2). For exa...
