  1. 3/4/2011 / The effect of short-term creatine-loading on active range of movement

     A standard creatine-loading protocol would significantly impair joint range of movement (ROM).

  2. 3/4/2011 / Nine weeks of supplementation with a multi-nutrient product augments gains in lean mass, strength, and muscular performance in resistance trained men.

     Creatine monohydrate, carbohydrates, and protein, when consumed before or during one's workout, have consistently shown to increase the gains from resistance training. Many supplements contain these ingredients, often in conjunction with other active ingredients. It is possible that other...

  3. 3/4/2011 /The effects of polyethylene glycosylated creatine supplementation on muscular strength and power

     Creatine is converted to phosphocreatine in the body, which plays a vital role in cellular energy production and muscle function. Creatine monohydrate supplementation coupled with resistance training has been demonstrated to improve multiple performance-related variables, and it is believed...

  4. 3/4/2011 /Low-dose creatine supplementation enhances fatigue resistance in the absence of weight gain

    Very low-dose creatine ingestion, when ingested over a sufficient period of time, will improve body composition, muscle function, and body creatine retention.

  5. Skill execution and sleep deprivation: effects of acute caffeine or creatine supplementation – a randomized placebo-controlled trial

    Sleep deprivation can cause a lack of energy and cognitive performance, thereby impacting the ability to perform skills that require high coordination and/or focus. Caffeine has been established to be able to partly compensate for sleep deprivation in regards to physical performance. Recently,...

  6. The influence of creatine supplementation on the cognitive functioning of vegetarians and omnivores

    Creatine and creatine phosphate are in dynamic equilibrium in the body. This system provides a readily available phosphate group to ADP to regenerate ATP energy. Muscle houses 95% of creatine, and the other 5% is mostly in the brain, heart, and testes (if applicable). Meats are one source of...

  7. Low-dose creatine supplementation enhances fatigue resistance in the absence of weight gain

    Creatine is a very common ergogenic supplement used in a variety of sports. A common method of beginning supplementation is creatine-loading, where an athlete consumes about 20-25 g of creatine per day for 5-7 days in order to rapidly increase muscle creatine stores in their body (typically 5 g 4...

  8. Creatine in type 2 diabetes: A randomized, double-blind, placebo-controlled trial

    There has been previous research showing that creatine can help improve insulin sensitivity, especially when coupled with an exercise regimen, and this study further corroborates this previous research. The decline in hemoglobin A1c due to creatine supplementation was approximately 1 percentage...

  9. Effect of a pre-workout energy supplement on acute multi-joint resistance exercise

    The participants were able to perform more repetitions in 4 sets with the supplement (26.3 ± 9.2) than with the placebo (23.5 ± 9.4 repetitions; p = 0.022). The supplement improved the performance for 6 of the 8 participants.

  10. Effects of combined creatine plus fenugreek extract vs. creatine plus carbohydrate supplementation on resistance training adaptations

    Creatine is one of the most widely used performance-enhancing supplements due to its safety and efficacy. There is some evidence that simultaneous carbohydrate intake helps increase creatine absorption, but high levels of simple sugars can lead to unhealthful spikes in blood sugar. Fenugreek seed,...

  11. Effect of caffeine ingestion after creatine supplementation on intermittent high-intensity sprint performance

    Creatine has repeated shown to increase work volume during exercise. However, more impressively, creatine has also shown many long term benefits such as increased rates of gain in muscle mass, strength, and power. A study that lasts for a longer term, for example 8 wks instead of 5 days, may be...

  12. Beneficial effect of creatine supplementation in knee osteoarthritis

    With a resistance training program, creatine can help alleviate the debilitating effects of OA to a greater extent than the resistance training program alone. This is important because it is common for those with OA to have reduced lower limb muscle size and strength, which can exacerbate their...

  13. Effects of three, five, and seven days of creatine loading on muscle volume and functional performance

    With a very short, 7 day intervention, creatine supplementation led to significantly improved performance metrics. While the placebo group showed slight improvements, differences were not statistically significant. Daily creatine supplementation led to greater gains than acute supplementation. It...

  14. Creatine supplementation does not augment muscle carnosine content in type 2 diabetic patients

    Creatine supplementation helps diabetic patients control their blood sugar. Carnosine is a small molecule composed of 2 amino acids (β-alanine and histidine) that is found in high concentrations in skeletal muscle. Carnosine deficiency has been associated with diabetes-like symptoms and there...

  15. Strength and hypertrophy responses to constant and decreasing rest intervals in trained men using creatine supplementation

    Creatine monohydrate (CR) supplementation during resistance training has been shown to increase muscle fiber hypertrophy and cross-sectional area. However, the mechanism of CR action is unclear and may include an enhanced capacity to restore cellular ATP concentrations, especially between exercise...

  16. Creatine supplementation attenuates hemodynamic and arterial stiffness responses following an acute bout of isokinetic exercise

    Compared with those who received placebo, men who received creatine supplementation for 3 weeks had attenuated post-exercise increases in HR, SBP, RPP, and brachial arterial stiffness following acute isokinetic exercise. No changes in at-rest cardiovascular measures were observed. A novel finding...

  17. Ingesting a pre-workout supplement containing caffeine, B-vitamins, amino acids, creatine, and beta-alanine before exercise delays fatigue while improving reaction time and muscular endurance

    Several ergogenic aids (compounds that enhance sports performance) have been identified as effective for most athletes. Among these ingredients are caffeine, creatine, branched chain amino acids (BCAAs), B-vitamins, and beta-alanine.

  18. A buffered form of creatine does not promote greater changes in muscle creatine content, body composition, or training adaptations than creatine monohydrate

    Supplementation with the buffered form of creatine (KA) did not provide the athletes a greater benefit than the traditional creatine monohydrate at the manufacturer’s recommended doses.  Performance enhancement was equivalent among all groups and there were no differences in clinical...

  19. A-Z of nutritional supplements: dietary supplements, sports nutrition foods and ergogenic aids for health and performance- Part 37

    Athletes who consume supplements and functional foods tend to combine ingredients, either intentionally or unintentionally.  It is important for athletes to be aware of what they are combining to prevent negative interactions and overdoses, as well as to increase the effects of their...

  20. Long-term creatine supplementation improves muscular performance during resistance training in older women

    Creatine increased gains in strength during a 12-week resistance training program in older women.  Importantly, creatine supplementation also accelerated the rate at which the women improved on everyday physical tasks such as standing from a chair or lying down.  These results imply that...

  21. The effects of pre versus post workout supplementation of creatine monohydrate on body composition and strength

    Consuming creatine after the workout may be more beneficial than consuming creatine before the workout in regard to increasing muscle mass and strength.

  22. Effects of combined creatine and sodium bicarbonate supplementation on repeated sprint performance in trained men

    This study showed that only 2 days of supplementation with both creatine and sodium bicarbonate increased the speed at which athletes completed cycling sprints. Both of these supplements are widely used and widely available (another name for sodium bicarbonate is baking soda) and may be an easy...
