materials and methods we divided 30 male wistar rats to three (n = 10) groups; including cr, wh and sham (water only) groups. each group was administered (by gavage) the supplements for an intermediate dosage during 25 days. after this period, they became anesthetized using a ketamine-xylazine (kx) and their time to anesthesia and analgesia, and total sleep time were recorded. results data were...

Rapid measurements of plasma creatine kinase activity using an inexpensive benchtop reflectance photometer (Ames Seralyzer) and disposable reagent strips were evaluated in the laboratory and coronary care unit. The system proved simple to use and capable of yielding rapid (four minutes per analysis), precise (coefficient of variation less than 9%), and accurate results (correlation with routine...

Background Resistance training (RT) enhances muscle protein synthesis and increases muscle strength and hypertrophy. Protein and amino acid supplements have been shown to augment the physiological improvements associated with RT such as improved body composition, muscular strength, and hypertrophy while suppressing exerciseinduced proteolysis. Supplements that also contain creatine and caffeine...

BACKGROUND Protein supplements are extensively used among commercial gym users and athletes. Although demographic information amongst such consumption has been poorly investigated. The aim of this study is to compare protein supplement consumption in commercial gym users, both from the city centre and the suburbs of Palermo, Italy. METHODS A face-to-face questionnaire has been administered to...

BACKGROUND Creatine monohydrate has become a very popular nutritional supplement for its ergogenic effects. The safety of creatine monohydrate has previously been confirmed. However with each novel form of creatine that emerges, its safety must be verified. Therefore, the purpose of this study was to examine the safety of a novel form of creatine, creatine nitrate (CN), over a 28 day period. ...

Athletes widely use nutritional supplements to increase muscle strength and endurance. This review aims summarize the effects of commonly used dietary on endurance in athletes. A literature search identified several studied for their impact performance, including protein supplements, creatine, beta-alanine, branched-chain amino acids (BCAAs), caffeine, nitrates, vitamins minerals. The discussed...

BACKGROUND Chronic supplementation with creatine monohydrate has been shown to promote increases in total intramuscular creatine, phosphocreatine, skeletal muscle mass, lean body mass and muscle fiber size. Furthermore, there is robust evidence that muscular strength and power will also increase after supplementing with creatine. However, it is not known if the timing of creatine supplementatio...

This study evaluated the effects of high-dose of short-term creatine supplementation (5g.kg(-1).day(-1) to 1 week) and long-term creatine supplementation (1g.kg(-1). day(-1) to 4-8 weeks) on kidney and liver structure and function of sedentary and exercised Wistar rats (Exercise sessions consisted of swimming at 80% of maximal work load supported during 5 days per week with daily sessions of 60...
