Abstract

The amino acid mixture (AA) lowered glucose response to a carbohydrate supplement after exercise, with a glucose area under the curve of 1259.9 ± 27.7 mmol/L for CHO/HAA.

  • Glucose responses and area under the curve for both CHO/HAA and CHO/LAA were significantly lower than CHO.
  • Glycogen storage rate was significantly lower in CHO/HAA compared to CHO, while CHO/LAA did not differ significantly from CHO.
  • CHO/HAA led to a significantly higher insulin response and greater activation of specific signaling proteins compared to CHO.
  • No differences were observed in the phosphorylation of certain proteins or blood lactate levels across the treatments.
