Values are total content, expressed as μmol of esterified lipid per gram of liver wet weight. n = 6 per group. TAG Triacylglycerol, DAG Diacylglycerol, ChE Cholesterol ester, CL Cardiolipin, LyPC Lysophosphatidylcholine, PC Phosphatidylcholine, PE Phosphatidylethanolamine, PS Phosphatidylserine, SM Sphingomyelin. Day 1: 3 h after exercise. Day 2: 28 h following exercise. Statistics by ANOVA. ^Main effect of trial, P < 0.05. &Trial-by-time interaction, P < 0.05. *Significantly different from CON within Day 1, p < 0.05. #Significantly different from CE within Day 1, P < 0.05
