Metabolic adaptation
Ingestion of long-chain triglyceride (LCT) solutions or infusion of intralipid before exercise leads to significant reductions in whole-body carbohydrate oxidation and decreased muscle glycogen utilization during moderate and intense dynamic exercise lasting 15-60 min.
Incorporating LCT solutions or intralipid infusions may help reduce carbohydrate usage during exercise.
StrongSupportsmedium confidence
Studies in which both untrained and well-trained subjects have ingested LCT solutions or received an infusion of intralipid (in combination with an injection of heparin) before exercise have reported significant reductions in whole-body carbohydrate oxidation and decreased muscle glycogen utilization during both moderate and intense dynamic exercise lasting 15-60 min.
Why this rating
The findings are based on studies involving both untrained and well-trained subjects.
