Protective Effects of Exercise Training (SOMEX)

Protective Effects of Exercise Training on Endothelial Dysfunction Induced by Total Sleep Deprivation in Healthy Subjects

Rationale. Sleep loss is a risk factor for cardiovascular events mediated through endothelial dysfunction.

Objective. To determine if 7 weeks of exercise training can limit cardiovascular dysfunction induced by total sleep deprivation (TSD) in healthy young men.

Methods: 16 subjects will be examined during 40-h TSD, both before and after 7 weeks of interval exercise training. Vasodilatation induced by ACh, insulin and heat (42°C) as well as pulse wave velocity (PWV), blood pressure and heart rate (HR) will be assessed at baseline, during TSD, and after one night of sleep recovery. Biomarkers of endothelial activation, inflammation, and hormones will bemeasured from morning blood samples at 07:00
