| Summary: | Insufficient sleep compromises lipid/glucose homeostasis. In opposition, exercise increases energy expenditure and has positive effects on glucose and fatty acid metabolism. Presently, it is hypothesized that exercise ameliorates metabolic dysfunction associated with sleep deprivation (SD). The effects of exercise (EX), SD and EX before SD. (EX+SD) on lipid and glucose metabolism were evaluated. Swiss mice were assigned to 4 groups (N=12, each) control, exercise (EX, 8 weeks, 1-hour of treadmill/9cm/s, 5x/week, from noon to 1:00 p.m.), SD (SD-72h, multiple platforms method), and exercise before SD (EX+SD). Exercise increased blood glucose, lactate and triglycerides (p<0.05). Both, SD and EX+SD reduced blood triglycerides (p<0.05). EX increased VLDL and reduced LDL; conversely, SD and EX+SD reduced VLDL and increased LDL. Hepatic triglycerides were markedly reduced by SD (p<0.05) and this was prevented by previous exercise (EX+SD). In summary, exercise improved essential cholesterol fractions and exercise before SD increased hepatic cholesterol and prevented hepatic triglycerides depletion. |
