Narrative review/book chapter summarizing literature without primary data or systematic review methodology
OpenAlex W2961503594 · doi:10.4324/9780429465567-7
What was done
This book chapter summarizes background literature on creatine metabolism and the effects of supplemental creatine monohydrate on health, exercise performance, and training adaptations.
What was found
The abstract reports that creatine monohydrate supplementation can increase intramuscular creatine and phosphorylcreatine concentrations by approximately 20% within seven days, with individual variation in response. The abstract describes the metabolic rationale for enhanced high-intensity exercise capacity and delayed fatigue, but provides no further quantitative performance metrics or specific trial results.
Why it matters
It provides a narrative summary of the metabolic mechanisms and typical magnitude of muscle creatine loading following short-term supplementation.
Limits
The work is a narrative review chapter rather than a systematic review or empirical trial. No search strategy, study quality assessment, population sample sizes, or primary statistical outcomes are provided in the abstract.
