Experts used to recommend a roughly weeklong “loading phase” in which you consume 20 to 25 grams of creatine daily to “saturate” your muscles before dropping to a lower dose.
This study details how women store 70 to 80 percent less creatine than men, and how hormone fluctuations (during menses, pregnancy, post-partum, during and post-menopause) affect creatine in the body.
Creatine supplements are marketed in ethyl ester, gluconate, monohydrate, and nitrate forms. [40] Creatine supplementation for sporting performance enhancement is considered safe for short-term use but there is a lack of safety data for long term use, or for use in children and adolescents. [41] Some athletes choose to cycle on and off creatine ...
Creatine conversion to phosphocreatine is catalysed by creatine kinase; spontaneous formation of creatinine occurs during the reaction. [7] Creatinine is removed from the blood chiefly by the kidneys, primarily by glomerular filtration, but also by proximal tubular secretion. Little or no tubular reabsorption of creatinine occurs. If filtration ...
In order to minimize injury and maximize results, a novice should begin at a comfortable level of muscular intensity and advance towards overload of the muscles over the course of an exercise program. [8] [9] Progressive overload requires a gradual increase in volume, intensity, frequency or time in order to achieve the targeted goal of the user.
Studies that focused on low doses of creatine (3g) taken over a long period of time (think two years) showed little effect on bone density or muscle gain in older women.
Excess post-exercise oxygen consumption (EPOC, informally called afterburn) is a measurably increased rate of oxygen intake following strenuous activity.In historical contexts the term "oxygen debt" was popularized to explain or perhaps attempt to quantify anaerobic energy expenditure, particularly as regards lactic acid/lactate metabolism; [1] in fact, the term "oxygen debt" is still widely ...
