16 APS exercise research highlights, from reduced flu mortality to proteomics & obesity
... increased rates of fat oxidation after 10 days of endurance exercise training (EET). Since 10 days of EET increases skeletal muscle fatty acid oxidation similarly in African-American and Caucasian women, EET should work as a treatment against obesity and diabetes for both. 33.14 L.

...of PPAR-delta produced muscle fibers that enhanced endurance exercise." By turning on PPAR-delta, the team had produced highly efficient muscle fibers that burned fat more rapidly. As a result, the mice were almost unable to gain weight even in the absence of exercise. "These muscles also provided resistance ...UCSD biologists develop 'super-endurance' strain of mice
