“…All the studies were monocentric. Five studies were conducted in Europe (Germany [37], Netherlands [38,39], Poland [40] and Sweden [15]), one in Brazil [26,41], eight in North America (Canada [42] and USA [16,24,25,35,43,44,45]), and four in Australia [23,36,46,47]. The duration between baseline and measures after supplementation ranged from 4 [46] to 180 days [26].…”

“…The duration between baseline and measures after supplementation ranged from 4 [46] to 180 days [26]. The nineteen included studies aimed to evaluate the effect of CS on performance or quality of life in elderly and patients with heart failure [25,26,37,45], among which nine studies aimed specifically at assessing aerobic performance 25 [15,16,23,24,35,36,42,43,47]. If seventeen studies were on heathy individuals, two studies recruited patients with heart failure [26,37] (Table 1).…”

Background: Despite creatine is well-known to increase performance in acute high intensity exercises, its role in aerobic performance based on VO2max is more controversial. Objectives:To perform a systematic review and meta-analysis on the effects of creatine supplementation on VO2max.Method: PubMed, Cochrane, Embase and ScienceDirect were searched for randomized controlled trials (RCTs) reporting VO2max in both a creatine supplementation and placebo group, after and before supplementation. We computed random-effects meta-analysis on VO2max at baseline, within groups following supplementation, on changes in VO2max between groups, as well after supplementation between groups. Sensitivity analyses were conducted after exclusion of studies outside funnel plots and on young and healthy individuals.Metaregressions were computed to search for influential factors of VO2max. Results:We included 19 RCTs for a total of 424 individuals (mean age 30 years old, 82% men).VO2max did not differ at baseline between groups (creatine and placebo). Both groups had a training in most studies (80%). Using changes in VO2max, VO2max increased in both groups but increased less after creatine than placebo (effect size -0.32, CI95% -0.51 to -0.12).Comparisons after supplementation confirmed a lower VO2max in the creatine group compared to the placebo group (-0.20, -0.39 to -0.001). Meta-analysis after exclusion from meta-funnel gave similar results, as well as in a subgroup of young and healthy participants. Metaregressions on characteristics of supplementation, physical training, or sociodemographic were not significant. Conclusion:Creatine supplementation has negative effect on VO2max, regardless of the characteristics of training, supplementation, or population characteristics.

“…Although this issue has not been fully addressed in the research literature, several studies have shown that ingesting Cr in greater than normal amounts may improve performance in short-term, all-out exercise (5,10,12,23,26,27). Furthermore, it has been proposed that, by increasing the amount of Cr in the body (in the form of PC) through supplementation, athletes may be able to more rapidly regenerate ATP stores, thereby improving performance in short-term, maximal exercise (15).…”

The use of creatine as an ergogenic aid for athletic performance is growing in popularity, despite limited scientific support for its efficacy. The purpose of this study was to determine the effect of creatine (Cr) monohydrate (CrM) and creatine phosphate (CrP) supplementation on strength, body composition, and blood pressure over a 6-week period. Thirty-five males (age range ϭ 19-29 years) with at least 2 years of strength training experience were tested on three separate occasions (pretest, 3 weeks, 6 weeks). Strength tests performed were the one-repetition maximum (1-RM) bench press, 1-RM leg press, and maximal repetitions on the seated preacher bar curl with a fixed amount of weight. Subjects were divided into three groups matched for strength: placebo (Pl), CrM, and CrP. All subjects were provided a standardized strength training regimen and ingested a loading dosage of 20 g per day for the first 3 days of the study, followed by a maintenance dose of 10 g per day for the remainder of the 6-week supplementation period. Significant differences were noted between the Pl group and the two Cr groups for changes in lean body mass, body weight, and 1-RM bench press. These results suggest that oral Cr supplementation will result in greater strength and fat-free mass development. In addition, CrP may be as effective as CrM in achieving these desired outcomes.
