BACKGROUND Obesity and low cardiorespiratory fitness are risk factors for cardiovascular diseases and type 2 diabetes. AIM To examine changes in cardiorespiratory fitness and cardiovascular risk factors after an exercise program without any dietary change in sedentary overweight teenagers. METHODS Fifteen obese young males (15.5 ± 0.8 years, 31.5 BMI ±(More)
Sirtuin 3 enzyme (SIRT3) is involved in the regulation of mitochondrial energy homeostasis by activating Peroxisome proliferator-activated receptor-gamma coactivator (PGC-1α). Murine models have shown that the protein SIRT3 was modified by exercise and diet, however, the effect of exercise without diet in humans has not been examined. Propose of this paper(More)
The beneficial effects of exercise have been recognized for many years yet the molecular mechanisms by which exercise show benefits on health are still elusive. A combination of experimental and bioinformatics approaches can be an invaluable tool to increase the cellular understanding of the molecular mechanisms that underlie the aerobic exercise in obese(More)
