Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study was to assess the usefulness of protein and carbohydrate supplementation, with and without creatine, on occupational performance in firefighters. Research has examined the effects of adding creatine to whey protein and carbohydrates on training adaptations in resistance-trained individuals with mixed finding.

Furthermore, the ergogenic benefit of protein and carbohydrate supplementation, with or without creatine, in firefighters is largely unknown. Therefore, the primary aim of the current study was to examine the effects of protein and carbohydrate supplementation, with or without creatine, on occupational performance in firefighters.
