Leptin administration increases fatty acid (FA) oxidation rates and decreases lipid storage in oxidative skeletal muscle, thereby improving insulin response. We have previously shown high-fat (HF) diets to rapidly induce skeletal muscle leptin resistance, prior to the disruption of normal muscle FA metabolism (increase in FA transport; accumulation of triacylglycerol, ...

There is no consensus on the best diet for exercise, as many variables influence it. We propose an approach that is based on the total energy expenditure of exercise and the specific macro- and micronutrients used. di Prampero quantified the impact of intensity and duration on the energy cost of ...

Regular physical activity decreases the risk of cardiovascular disease and modifies multiple cardiovascular risk factors. The optimum amount of exercise continues to generate debate; however, the general recommendation is that all adults should engage in 30 min of moderate-intensity physical activity on five, and preferably all, days of the week. Despite ...

Vigorous exercise increases the risk of vascular thrombotic events. Shear stress enhances the shedding of procoagulant microparticles from platelets, and triggers thrombin generation (TG) in blood. This study explicates the manner in which strenuous exercise affects platelet-derived microparticles (PDMP) release and PDMP-mediated TG under various physio-pathological shear flows. Twenty-four sedentary ...
