Role of skeletal muscle‐fibre type in regulation of glucose metabolism in middle‐aged subjects with impaired glucose tolerance during a long‐term exercise and dietary intervention

Aim: The aim of this study was to investigate the role of skeletal muscle fibre type in the regulation of glucose metabolism in middle‐aged obese subjects with impaired glucose tolerance (IGT) during a 2‐year exercise and dietary intervention. Methods: Muscle biopsies (musculus vastus lateralis) were taken from 22 subjects belonging to the intervention group of the Finnish Diabetes Prevention Study [ 1 ]. According to their myosin heavy chain...
