Abstract Fifteen middle-aged, untrained (defined as no regular exercise) men (mean age 49.9 years, range 42-67) cycled on a cycle ergometer at 50 rpm for 30 min at an intensity producing 60% predicted maximum heart rate [(fc,max), where fc, max = 220 - age]. Total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C) and triglyceride (Tg) concentrations were measured from fasting fingertip capillary blood samples collected at rest, after 15 and 30 min of exercise, and at 15 min post-exercise. The mean HDL-C level increased significantly from the resting level of 0.85 mmol · l-1 to 0.97 mmol · 1-1 (P<0.05) after 15 min of exercise, increased further to 1.08 mmol · 1-1 (P<0.01) after 30 min of exercise and remained elevated at 1.07 mmol · 1-1 (P<0.01) at 15 min post-exercise. These increases represented changes above the mean resting level of 14.1%, 27.1% and 25.9% respectively. The HDL-C/LDL-C ratio increased significantly from a resting ratio of 0.20 to 0.26 after 30 min of exercise (P < 0.01) and to 0.24 at 15 min post-exercise (P<0.05). The mean Tg level increased significantly from a resting level of 0.88 mmol · 1-1 to 1.05 mmol · 1-1 after 15 min, and to 1.06 mmol · I-1 after 30 min of exercise (P<0.05 at each time). The TC/HDL-C ratio decreased significantly (P=0.05) after 30 min of exercise and at 15 min post-exercise by 18.8% and 14%, respectively. No significant changes were observed in the levels of TC or LDL-C over time. These results indicate that 30 min of moderate exercise elicits significant changes in HDL-C concentration during and up to 15 min after the exercise in untrained middle-aged men with low mean resting levels of HDL-C (0.85 mmol · 1-1).
