Table 2. Metabolic fitness at baseline. Data are means (±SD). Control (n=16) Stairclimbing (n=29) Total Cholesterol (mmol·L 4.75 (.85) 4.92 (.98) HDL-C (mmol·L-1) 1.19 (.40) 1.00 (.34) LDL-C (mmol·L-1) 2.73 (.80) 2.93 (.74) TC: HDL-C ratio 4.60 (2.32) 5.55 (2.28) Triglycerides (mmol·L-1) .85 (.44) .99 (.55) No significant differences between groups (p > 0.05). HDL-C = high density lipoprotein cholesterol, LDL-C = low density lipoprotein cholesterol, TC:HDL-C = ratio of total cholesterol to high density lipoprotein cholesterol.
