improving anaerobic performance and anaerobic power is the critical aspect on successfully in competitions for many athletes. the purpose of current research was to investigating the effect of various pre-competitions warm-up on anaerobic performance. it has been shown that, differences pre-competitions activity may effect on anaerobic and explosive performance. effect of general warm-up, witho...

Muscle contraction results in phosphorylation and activation of the AMP-activated protein kinase (AMPK) by an AMPK kinase (AMPKK). LKB1/STRAD/MO25 (LKB1) is the major AMPKK in skeletal muscle; however, the activity of LKB1 is not increased by muscle contraction. This finding suggests that phosphorylation of AMPK by LKB1 is regulated by allosteric mechanisms. Creatine phosphate is depleted durin...

Mitochondrial adenine nucleotide translocation was measured in the presence of creatine or creatine phosphate to test the proposed functional couple between the nucleotide translocase and creatine kinase. Rat heart mitochondria were preloaded with the corresponding nucleotide which reacts with creatine kinase only after it is transported across the mitochondrial membrane; namely, radioactive AT...

We have studied the expression of creatine kinase (CK) and the accumulation of creatine phosphate during the differentiation of human and mouse peripheral blood monocytes. Mouse monocytes cultured for 24 h do not contain detectable levels of CK and creatine phosphate. However, resident tissue macrophages and inflammatory elicited macrophages obtained from the peritoneal cavities of mice have 70...

Mitochondrial creatine kinase was first proposed to act as a functional component in respiratory control in 1966 (Bessman, S. P., and Fonyo, A. (1966) Biochem. Biophys. Res. Commun. 22, 597-602). Since that time, evidence has accumulated to support the theory of a creatine-phosphorylcreatine shuttle mechanism involved in supplying energy for aerobic muscle contraction (Bessman, S. P., and Geige...

The objective of the study was to develop a simple, specific and stability-indicating HPLC method for the simultaneous determination of creatine phosphate sodium (CPS) and its related substances in pharmaceutical formulation. Separation of creatine phosphate sodium from its major process impurities and degradation products was achieved on a Hypersil BDS C18 column (250 × 4.6 mm, 5 μm) with an a...

An enzyme is present in extracts of rabbit alveolar macrophage which can catalyze the reaction of creatine phosphate with adenosine diphosphate to form adenosine triphosphate and creatine. The enzyme is moderately activated by reduced glutathione, has a pH optimum between pH 6.5 and 7.0, and shows an absolute requirement for Mg(2+). The K(m) for creatine phosphate is approximately 3.6 mm while ...

Creatine phosphate serves as a reuseable high energy phosphate reservoir in skeletal and cardiac muscle and in the brain. These stores of creatine phosphate are thought to rephosphorylate the ATP hydrolyzed during cellular work (see 1 and 2 for review). Studies in our laboratory (3) have shown that mononuclear phagocytes obtained from the peritoneal cavities of mice also contain large stores of...
