Adipositas & körperliche Aktivität
A sedentary lifestyle is a strong and independent risk factor for many chronic diseases. In most cases, inadequate levels of physical activity are linked to a persistent, sterile inflammation, both locally in various organs as well as systemically. Inversely, exercise is an efficient intervention fo...

In recent years, the peroxisome proliferator-activated receptor coactivator 1(PGC-1) has emerged as a regulatory nexus of muscle adaptation to endurance exercise. Muscle PGC-1not only promotes an oxidative, slow-twitch muscle fiber type, but also modulates the phenotype of non-muscle cells.
