Effects of β-Hydroxy-β-methylbutyrate Free Acid Ingestion and Resistance Exercise on the Acute Endocrine Response
(a) Plasma insulin-like growth factor (IGF-1) concentration values for placebo (PL) and β-hydroxy-β-methylbutyrate free acid (HMB-FA) groups before exercise (PRE), immediately after exercise (IP), and 30 minutes after exercise (30P). †Both groups significantly lower than PRE values. (b) Area under the curve (AUC) analysis for plasma IGF-1 levels for PL and HMB-FA groups. Data were reported as mean ± SD.Indicating HMB-FA group significantly greater than PL.
