Eur J Clin Invest 2010; 40 (8): 759–765 Abstract Background This study examined the effects of acute supramaximal exercise (∼115% VO 2max ) on the blood lipid profile for three different carbohydrate (CHO) storage levels (control, low and high). Methods Six male subjects were randomly divided into three different groups: control, low CHO and high CHO. These groups differed in the diet to which the subjects were submitted before each exercise session. The lipid profile [triglycerides (TG), very low‐density lipoprotein (VLDL), high‐density lipoprotein (HDL)‐cholesterol, low‐density lipoprotein (LDL)‐cholesterol, TG/HDL‐C ratio and total cholesterol) was determined at rest, immediately after exercise and 1 h after exercise bouts. Results The time to exhaustion was lower in the low CHO condition compared with the control and high CHO condition (3·59 ± 0·72; 2·91 ± 0·56; and 4·26 ± 0·69 min; P < 0·05). The energy expenditure (control: 251·1 ± 56·0 kJ; low CHO: 215·2 ± 28·6 kJ; and high CHO: 310·4 ± 64·9 kJ) was significantly different between the low and high CHO conditions ( P < 0·05). There were no significant changes in the lipid profile for any of the experimental conditions (control, low and high; P < 0·05). Glucose and insulin levels did not show time‐dependent changes in any of the conditions ( P > 0·05). Conclusions These results indicate that a supramaximal exercise session has no significant effects on lipid metabolism.
