P>BackgroundThis study examined the effects of acute supramaximal exercise (similar to 115% VO(2max)) on the blood lipid profile for three different carbohydrate (CHO) storage levels (control, low and high).MethodsSix 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.ResultsThe time to exhaustion was lower in the low CHO condition compared with the control and high CHO condition (3 center dot 59 +/- 0 center dot 72; 2 center dot 91 +/- 0 center dot 56; and 4 center dot 26 +/- 0 center dot 69 min; P < 0 center dot 05). the energy expenditure (control: 251 center dot 1 +/- 56 center dot 0 kJ; low CHO: 215 center dot 2 +/- 28 center dot 6 kJ; and high CHO: 310 center dot 4 +/- 64 center dot 9 kJ) was significantly different between the low and high CHO conditions (P < 0 center dot 05). There were no significant changes in the lipid profile for any of the experimental conditions (control, low and high; P < 0 center dot 05). Glucose and insulin levels did not show time-dependent changes in any of the conditions (P > 0 center dot 05).ConclusionsThese results indicate that a supramaximal exercise session has no significant effects on lipid metabolism.
