This letter to the editor argues that the assumption of a single value for the acetate recovery factor in carbon-13 stable isotope research for different individuals, can lead to significant errors in the outcomes of substrate utilization measurements.

Review of the effects of physical activity on insulin sensitivity

Proefschrift dat onder andere een tweejarig interventie-onderzoek beschrijft naar het effect van een bewegingsprogramma bij personen met type 2 diabetes.

Immunofluorescence microscopy in this study shows that GLUT-4 protein expression is fibre-type specific within a muscle. It is postulated that both fibre-type-dependent and fibre-type-independent factors affect GLUT-4 expression.

The data of this study indicate that the acetate recovery factor, used in stable isotope research, needs to be deteremined in every subject, under similar conditions as used for the tracer-derived determination of substrate oxidation.

This research article shows that a high intensity exercise program compared to a low intensity exercise program of the same session duration and frequency, increases insulin sensitivity to a larger extend in healthy subjects. It also shows that the short insulin tolerance test can be used to detect differences …

The results of this study indicate that whole body metabolic and cardiovascular responses to 140 min of either steady state or variable intensity exercise at the same average intensity are similar, despite differences in skeletal muscle carbohydrate metabolism and recruitment

This paper descibes a study that shows that glycogen-lowering exercise, performed the evening before an exercise bout in combination with glycogen restriction leads to a reduction of the oxidation rate of ingested glucose during moderate-intensity exercise

"In dit onderzoek is gekeken naar het verband tussen de ambities van de gemeente Almere, de marktvraag en de praktijk. Het doel van dit onderzoek is om antwoord te krijgen op de vraag of het huidige kavelaanbod (de praktijk) van de gemeente Almere overeenkomt met de ambities en de marktvraag. Het …
