SOURCE-LINKED STUDY SUMMARY
Dietary Carbohydrate Intake and Skeletal Muscle Glycogen: A Systematic Review and Meta-Analysis to Determine Optimal Carbohydrate Loading Strategies.
Abstract summarizedQuality not appraised
- What was studied
- A systematic review examined carbohydrate availability and biopsy-measured muscle glycogen.
- Who / model studied
- 63 trials with 641 participants; 18 trials entered the meta-analysis.
- Studied dose & schedule
- Carbohydrate availability for at least 24 hours; lower intakes below 6.5 versus higher intakes above 6.5 g/kg/day.
- What the study found
- Higher intake increased glycogen by 191.9 mmol/kg dry muscle (95% CI 142.8–241.1). Heterogeneity was substantial: 94%.
- Limitations & context
- Glycogen storage is not contractile-muscle growth or proven competition benefit. Designs, prior exercise and loading durations differed. Abstract assessment; no clinical safety synthesis.
