Intervention

Outcome measures

Primary outcome

1. Ex vivo mitochondrial function;

2. In vivo mitochondrial function;

3. Insulin sensitivity;

4. Fat accumulation in muscle and heart;

5. Indirect calorimetry.

Secondary outcome

1. Plasma glucose;

2. Plasma insulin;

3. Plasma free fatty acids;

Background summary

We found a reduced basal ADP-stimulated and maximal mitohondrial respiratory capacity related to type 2 diabetes, which underlies the reduction in in vivo mitochondrial function, independent of mitochondrial content.

Study objective

Does lipid accumulation in skeletal muscle and the heart effect mitochondrial function in relation to insulin resistance?

Study design

1. All metabolic measurements for one patient planned within one month.
2. All subjects underwent these metabolic measurements within 1.5 year.

Intervention

No intervention is performed.
