Values are mean ± SEM; n = 8. CON, non-exercised control condition. EX-DEF, morning after prolonged exercise without carbohydrate replacement and thus during carbohydrate deficit; EX-BAL, morning after prolonged exercise with sufficient carbohydrate replacement to restore carbohydrate and energy balance following exercise. Large, medium and small VLDL are defined as 55 – 260 nm, 43 – 55 nm and 29 – 43 nm diameters respectively with data also presented for 70 – 120 nm range (subset of large). IDL, large LDL and small LDL are defined as 23 – 27 nm, 21.2 – 23 nm and 18 – 21.2 nm diameters, respectively. Large HDL, medium HDL and small HDL are defined as 8.8 - 13 nm, 8.2 – 8.8 nm and 7.3 – 8.2 nm diameters respectively. Differences assessed using one-way repeated measures ANOVA followed by LSD post-hoc. *p < 0.05 vs CON; **p < 0.05 compared to EX-DEF; □ data log-transformed prior to statistical analysis.
