Conclusions
In general, the results showed that supplementation with Cr-HCl and CrM increases GH, IGF-1 levels, the ratio of follistatin/myostatin, testosterone/cortisol, muscle strength (bench press, leg press), arm and thigh MCSA, SMM and significantly decreases cortisol, ACTH levels and PBF. Hormonal adaptations, strength and body composition in the RT+Cr-HCl group were not significant compared to the RT+CrM-LP and RT+CrM-WLP groups and only changes in the supplementary groups were significant compared to the control group.
The results showed the effects of Cr-HCl and CrM on hormonal compatibility, strength and hypertrophy, but Cr-HCl does not seem to have more effects than CrM. Despite claims of increased solubility, bioavailability, and superior absorption mechanisms, there is currently no evidence to support the use of Cr-HCl instead of CrM. Although Cr-HCl affects performance and hormonal indicators, due to its very high price compared to CrM, its use is not economical and it cannot replace CrM. Considering the very few studies in this regard, for more accurate conclusions, more studies are needed in different age groups and athletes of different fields, at different levels of sports and with longer supplementation periods.
