“…Although there was no differences between the groups in the end of the protocol, once again, if we put the results in context and understand that the protocols were developed in very similar conditions, the lack of increase in the weight of the HClG is in accordance with other studies of our group 20,22 and contributes to the hypothesis that this type of creatine might have less impact on the weight of athletes due to less water retention.…”

“…That performance improvement, a literature consensus, made creatine a good target to molecular improvements. Some attempts, despite of the changes on the molecule, yielded no effective improvements when compared to regular monohydrate creatine 33 , but the addition of a HCl radical to it, making it a more soluble salt seems to be an effective process 22 .…”

“…Both CrHCl groups resulted in significantly decreased FM (high: p = 0.034; low: p = 0.005) while FFM was significantly increased only in the high CrHCl group. 75 It was concluded that both CrHCl and CrH2O promote gains in strength but only CrHCl promotes significant changes in body composition with differences in doses, which contradicts other research showing that CrH2O can positively influence body composition (eg, increase fat free mass, decrease fat mass). 75 However, it is important to note that participants in this study were asked to refrain from any form of resistance training 4 wk prior to the start of the study, which may have had an impact on strength and body composition results.…”

“…1RM leg press was significantly increased (p < 0.05) in all groups while 1RM bench press was only significantly increased in the low CrHCl group (p = 0.003). 75 Between group differences were not found. Both CrHCl groups resulted in significantly decreased FM (high: p = 0.034; low: p = 0.005) while FFM was significantly increased only in the high CrHCl group.…”

“…75 Participants (n = 30; both sexes) were randomly divided into one of the four groups and underwent a given treatment while adhering to a prescribed 4 wk resistance training protocol. 1RM bench press and leg press were assessed both pre-and post-experiment as well as body-composition (skin fold).…”
The purpose of this study was to examine the acute effects of oral creatine hydrochloride (CrHCl) supplementation on three repeated bouts of bench press and vertical jumping exercises and body composition measures (body weight (BW), fat-free mass (FFM) and fat mass (FM)). Methods: Fifteen resistance trained males completed 3 sets of the barbell bench press (70% 1RM) and 3 sets of the repeated counter-movement vertical jump (CMJ; 85% maximal CMJ height), with 2 min rest between sets, before and after a 7 d CrHCl intervention (4 g·day -1 ). A two-factor repeated measures ANOVA was used to determine significant main effects (time and set) with post-hoc Bonferroni analysis and interaction effects (time x set) for bench press and CMJ performances from pre-to post-intervention. A one-factor repeated measures ANOVA was used to assess pre-to post-intervention differences in body composition. Results: Significant main and interaction effects for time and set were found in the bench press from pre-to postintervention (p < 0.005, for all) with Bonferroni analysis indicating increased performance on later sets (eg, Set 3 > Set 2 > Set 1, p < 0.005). Significant main effects for time and set were found in the CMJ test from pre-to post-intervention (p < 0.005) but no interaction effect was found (p > 0.05). Post hoc analysis indicated increased performance on later sets. BW was the only body measure to reach significance (p < 0.005). Conclusion: Supplementation with 4 g of CrHCl for 7 d in healthy, resistance trained men significantly increased the number of repetitions performed during intermittent bouts of submaximal bench press and CMJ exercises and body weight.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
