a
Significantly lower from all other times within exercise modality (P < 0.05).
b
Significantly greater during running compared to walking within times (P < 0.001).
CHOLtot, total cholesterol; HDL, high-density lipoprotein; LDL, low-density lipoprotein; TG, triglycerides; Δ PV, change in plasma volume. Values are represented as mean (±SD).
