Eligibility
Inclusion criteria
Inclusion criteria: Young healthy male subjects. Age 18-30 years.
Exclusion criteria
Exclusion criteria: A drastic recent change in physical activity (eg. just stopped being an athlete), conditions that can significantly influence the amount of energy that is needed for physical activity (eg. a lower-leg prothesis), history of obesity, hypertension, diabetes mellitus, hyperlipidemia, smoking (currently, or > 1 package per month over the last 2 years), documented cardiovascular disease, use of medication that could potentially affect insulin sensitivity or microvascular function or inflammatory status.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The effect of FFA on insulin-induced changes in microvascular blood volume of skeletal muscle and myocardium will be correlated with amount of physical activity as measured with accelerometers and VO2max. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secundary endpoints will be microvascular blood volume during basal and hyperinsulinemic state without Intralipid infusion, in myocardium and skeletal muscle. Also, whole-body insulin sensitivity as measured by the glucose infusion rate will be correlated with physical activity. Body fat percentage and blood pressure (Nexfin) will be measured to test if these parameters are equal between subjects and if not in which amount they differ. Contraction induced microvascular recruitment will be measured with the handgrip dynamometer to test if we can show an increase of MBV with Ceus during a different physiological parameter than insulin alone. | — |
