“…The basic premise behind the use of a 5-to 6-day loading phase is to maximize muscle creatine concentrations in a short period of time (12). Still, other studies using a similar loading-phase dosing regimen and supplement duration were unable to see any significant performance improvements (6,7,16,25). This was likely related to the performance variable evaluated.…”

ABSTRACT. Hoffman, J.R., J.R. Stout, M.J. Falvo, J. Kang, and N.A. Ratamess. Effect of low-dose, short-duration creatine supplementation on anaerobic exercise performance. J. Strength Cond. Res. 19(2):260-264. 2005.-To examine the efficacy of a low-dose, short-duration creatine monohydrate supplement, 40 physically active men were randomly assigned to either a placebo or creatine supplementation group (6 g of creatine monohydrate per day). Testing occurred before and at the end of 6 days of supplementation. During each testing session, subjects performed three 15-second Wingate anaerobic power tests. No significant (p Ͼ 0.05) group or time differences were observed in body mass, peak power, mean power, or total work. In addition, no significant (p Ͼ 0.05) differences were observed in peak power, mean power, or total work. However, the change in the rate of fatigue of total work was significantly (p Ͻ 0.05) lower in the creatine supplementation group than in the placebo group, indicating a reduced fatigue rate in subjects supplementing with creatine compared with the placebo. Although the results of this study demonstrated reduced fatigue rates in patients during high-intensity sprint intervals, further research is necessary in examining the efficacy of low-dose, short-term creatine supplementation.

Following a request from the European Commission, the Panel on Dietetic Products, Nutrition and Allergies was asked to provide a scientific opinion on a list of health claims pursuant to Article 13 of Regulation (EC) No 1924No /2006. This opinion addresses the scientific substantiation of health claims in relation to creatine and increase in physical performance during short-term, high intensity, repeated exercise bouts, increase in endurance capacity, and increase in endurance performance. The scientific substantiation is based on the information provided by the Member States in the consolidated list of Article 13 health claims and references that EFSA has received from Member States or directly from stakeholders.The food constituent that is the subject of the health claims is creatine. The Panel considers that creatine is sufficiently characterised. Increase in physical performance during short-term, high intensity, repeated exercise boutsThe claimed effects are "energy metabolism", "muscular effort", "bodily constitution", "increasing strength", "increasing mass", "increasing power", "increasing performance", "muscular

“…To determine upper and lower body strength measures, all subjects underwent a multiple repetition maximum (mRM) bilateral machine incline leg press (LP) and a free weight bench press (BP) test, as previously reported by Syrotuik et al (19). Briefl y, this involved measuring the maximum weight that each subject could lift to failure for eight repetitions of each strength exercise using a standardized protocol.…”

“…Initial training loads were established from the mRM strength assessment on each exercise, as previously noted. Volume and intensity were progressively overloaded using a periodized program with the aid of a computer software program (B. E. Software) (19). Core lifts were progressively overloaded using 70 to 95% of predicted 1RM and between 2 to 10 repetitions for 4 to 5 sets while supplementary lifts were overloaded using ranges of 65 to 85% of predicted 1RM, 8 to 10 repetitions for 2 to 3 sets.…”

To examine the effects of elk velvet antler supplementation (EVA) combined with training on resting and exercise-stimulated hormonal response, male (n = 25) and female (n = 21) rowers ingested either EVA (560 mg/d) or placebo (PL) during 10 wk of training. VO(2max), 2000 m rowing time, leg and bench press strength were determined before and after 5 and 10 wk of training. Serum hormone levels were measured prior to and 5 and 60 min after a simulated 2000 m rowing race. VO(2max)and strength increased and 2000 m times decreased similarly (P < 0.05) with training. There was no significant difference between the EVA and PL group for any hormonal response. Testosterone (males only) and growth hormone (both genders) were higher 5 min after the simulated race (P < 0.05) but returned to baseline at 60 min. Cortisol was higher 5 and 60 min compared to rest (both genders) (P < 0.05) and was higher 60 min post-exercise following 5 and 10 wk of training. It appears that 10 wk of EVA supplementation does not significantly improve rowing performance nor alter hormonal responses at rest or after acute exercise than training alone.
