Creatine and phosphocreatine: A review of their use in exercise and sport
- The effect of Creatine on Nitrogen Balance. Feliciano, Jeff // Joe Weider's Muscle & Fitness;Jun95, Vol. 56 Issue 6, p68
Examines the physiological effect of creatine phosphate. Reason for the popularity of creatine as a nutritional supplement; Required dosage of creatine for muscle growth.
- The Recovery of Repeated-Sprint Exercise Is Associated with PCr Resynthesis, while Muscle pH and EMG Amplitude Remain Depressed. Mendez-Villanueva, Alberto; Edge, Johann; Suriano, Rob; Hamer, Peter; Bishop, David // PLoS ONE;Dec2012, Vol. 7 Issue 12, p1
The physiological equivalents of power output maintenance and recovery during repeated-sprint exercise (RSE) remain to be fully elucidated. In an attempt to improve our understanding of the determinants of RSE performance we therefore aimed to determine its recovery following exhaustive exercise...
- Mechanisms of muscular adaptations to creatine supplementation. Rawson, Eric S.; Persky, Adam M. // International SportMed Journal;2007, Vol. 8 Issue 2, p43
Creatine supplementation is a widely used and heavily studied ergogenic aid. Athletes use creatine to increase muscle mass, strength, and muscle endurance. While the performance and muscle-building effects of creatine supplementation have been well documented, the mechanisms responsible for...
- Myocardial Energy Transport and Heart Failure. Portman, Michael A.; Zhang, Jianyi // Current Cardiology Reviews;2005, Vol. 1 Issue 1, p17
Abnormalities in myocardial energy metabolism occur in association with progression to congestive heart failure. Conceivably, alterations in cardiac energy metabolism may initiate trophic responses or remodeling noted in myocardium during various disease processes. This review will explore the...
- NEW AND IMPROVED CREATINE. Stoppani, Jim // Joe Weider's Muscle & Fitness;May2004, Vol. 65 Issue 5, p154
Provides information on several creatine supplements. Creatine monohydrate; Creatine citrate; Creatine phosphate.
- Effect of Î±-Lipoic Acid Combined With Creatine Monohydrate on Human Skeletal Muscle Creatine and Phosphagen Concentration. Burke, Darren G.; Chilibeck, Philip D.; Candow, Darren G.; Parise, Gianni; Tarnopolsky, Mark A. // International Journal of Sport Nutrition & Exercise Metabolism;Sep2003, Vol. 13 Issue 3, p294
Î±-lipoic acid has been found to enhance glucose uptake into skeletal muscle in animal models. Studies have also found that the co-ingestion of carbohydrate along with creatine increases muscle creatine uptake by a process related to insulin-stimulated glucose disposal. The purpose of this...
- Analyzing the Functional Properties of the Creatine Kinase System with Multiscale 'Sloppy' Modeling. Hettling, Hannes; van Beek, Johannes HGM // PLoS Computational Biology;Aug2011, Vol. 7 Issue 8, p1
In this study the function of the two isoforms of creatine kinase (CK; EC 184.108.40.206) in myocardium is investigated. The 'phosphocreatine shuttle' hypothesis states that mitochondrial and cytosolic CK plays a pivotal role in the transport of highenergy phosphate (HEP) groups from mitochondria to...
- Systems bioenergetics of creatine kinase networks: physiological roles of creatine and phosphocreatine in regulation of cardiac cell function. Guzun, R.; Timohhina, N.; Tepp, K.; Gonzalez-Granillo, M.; Shevchuk, I.; Chekulayev, V.; Kuznetsov, A.; Kaambre, T.; Saks, V. // Amino Acids;May2011, Vol. 40 Issue 5, p1333
Physiological role of creatine (Cr) became first evident in the experiments of Belitzer and Tsybakova in 1939, who showed that oxygen consumption in a well-washed skeletal muscle homogenate increases strongly in the presence of creatine and with this results in phosphocreatine (PCr) production...
