Brief Summary:
The experiment is a simple cross-sectional study with three groups n10 in each group young and old healthy men and obese young men The study will investigate the composition of the adipose tissue extra cellular matrix
The main questions to answer
- is there differences in the adipose tissue extracellular matrix in obese compared to young men is there differences in the adipose tissue extracellular matrix in old compared to young men
The main questions to answer
- is there differences in the adipose tissue extracellular matrix in obese compared to young men is there differences in the adipose tissue extracellular matrix in old compared to young men
Detailed Description:
Three groups of young n10 and old n10 healthy men and obese young n10 men are recruited
After verbal and written information is provided signed consent is obtained
Subjects arrive at the lab overnight fasted and not having done exercise the prior day and having consumed a normal isocaloric carbohydrate rich diet
After a voiding and a 15 min rest body composition is determined by DXA After this blood pressure is measured in the supine position in triplicate separated by 1 min Following this a venous blood sample is obtained from a cubital vein and kept on ice until further handling
Subsequently an adipose tissue biopsy is obtained by the Bergström technique applied with suction from an incision 3-5 cm lateral from the umbilicus After compression and a 30 min rest the subject perform an incremental exercise test to determine maximal fat oxidation In brief pulmonary oxygen uptake and carbon dioxide excretion is measured using a COSMED Quark B2 on-line system during 5 min rest sitting on a cycle ergometer and then during exercise with 3 min increments starting at 60 Watt and increasing by 35 watts When the respiratory exchange ratio is above 1 the exercise is stopped After a 5 min break an incremental test until voluntary exhaustion is performed to determine maximal oxygen uptake This completes the experiment
