Creatine, Creatine Kinase, and Aging
2018With an ever aging population, identifying interventions that can alleviate age-related functional declines has become increasingly important. Dietary supplements have taken center stage based on various health claims and have become a multi-million dollar business.

CRC Critical Reviews in Clinical Laboratory Sciences, 1982
Creatine kinase is present in significant concentrations in skeletal muscle and cardiac muscle and to a lesser extent in gastrointestinal tract and brain tissue. The enzyme has been purified from a variety of tissues and an examination of its kinetic and physical properties reveal that the enzyme consists of two subunits and can exist as three ...

Current Sports Medicine Reports, 2013
Creatine monohydrate is a dietary supplement that increases muscle performance in short-duration, high-intensity resistance exercises, which rely on the phosphocreatine shuttle for adenosine triphosphate. The effective dosing for creatine supplementation includes loading with 0.3 g·kg·d for 5 to 7 days, followed by maintenance dosing at 0.03 g·kg·d ...

Amino Acids, 2011
Creatine monohydrate (Cr), the most diffuse supplement in the sports industry, is receiving greater attention because of its beneficial effects in a wide number of human degenerative diseases and conditions. These effects can be barely explained on the basis of the sole ergogenic role of the Cr/CrP system.

Creatine metabolism and the consequences of creatine depletion in muscle
Molecular and Cellular Biochemistry, 1994Currently, considerable research activities are focussing on biochemical, physiological and pathological aspects of the creatine kinase (CK)-phosphorylcreatine (PCr)-creatine (Cr) system (for reviews see [1,2]), but only little effort is directed towards a thorough investigation of Cr metabolism as a whole.

Creatine in Humans with Special Reference to Creatine Supplementation
Sports Medicine, 1994Since the discovery of creatine in 1832, it has fascinated scientists with its central role in skeletal muscle metabolism. In humans, over 95% of the total creatine (Crtot) content is located in skeletal muscle, of which approximately a third is in its free (Crf) form. The remainder is present in a phosphorylated (Crphos) form. Crf and Crphos levels in

Research has demonstrated that creatine supplementation has some therapeutic benefit with respect to muscle function and more recently neurological function. Despite the growing body of literature on the pharmacologic effect of creatine, very little is known about the disposition of creatine after supraphysiologic doses.

Journal of Applied Physiology, 2003
The total creatine pool size [Crtotal; creatine (Cr) + phosphocreatine (PCr)] is crucial for optimal energy utilization in skeletal muscle, especially at the onset of exercise and during intense contractions. The Crtotallikely is controlled by long-term modulation of Cr uptake via the sodium-dependent Cr transporter (CrT).

There are two viewpoints regarding the role of the enzyme creatine Phosphokinase (CPK), which catalyzes the reversible transphosphorylation of creatine and adenine nucleotides in energy transport. The classical viewpoint (Fig. 1) regards CPK as a near equilibrium enzyme buffering cytosolic changes in nucleotide concentration (1,2), with creatine ...
