At rest and during exercise carbohydrate and fat are the predominant substrates. They are oxidized simultaneously but the relative contribution of these two substrates is dependent on a variety of factors including the exercise intensity and duration, diet, environmental conditions and training status. Changes in carbohydrate metabolism during the transition from rest to exercise and from low- to high-intensity exercise are mainly due to allosteric regulation. The factors that up-regulate fat…

Sex Hormones and Substrate Metabolism During Endurance Exercise
The sex differences and the effects of menstrual cycle, oral contraceptives, menopause and hormone replacement therapy on substrate metabolism during endurance exercise are described.
Influence of Hormonal Status on Substrate Utilization at Rest and during Exercise in the Female Population
The primary purpose of this review was to identify the impact of hormonal status on substrate oxidation among female subjects at rest and during exercise and to describe gender differences in substrate utilization during exercise.
Exercise and Regulation of Protein Metabolism.
Beyond the Calorie Paradigm: Taking into Account in Practice the Balance of Fat and Carbohydrate Oxidation during Exercise?
There is increasing evidence that training targeted at this level is efficient for reducing fat mass, sparing muscle mass, increasing the ability to oxidize lipids during exercise, lowering blood pressure and low-grade inflammation, improving insulin secretion and insulin sensitivity, reducing blood glucose and HbA1c in type 2 diabetes, and decreasing the circulating cholesterol level.
The effect of increased lipid intake on hormonal responses during aerobic exercise in endurance-trained men.
Data suggest that acute negative energy balance induced by exercise elicits a hormonal response with opposite changes of ghrelin and leptin, and the hormonal response is modulated by the preceding intake of fat.
High-Fat Diet Increases Fat Oxidation and Promotes Skeletal Muscle Fatty Acid Transporter Expression in Exercise-Trained Mice.
Results suggest that HFD intake effectively increased fat utilization as an energy substrate during long-term endurance exercise.

In women, the realization of an exercise in either the fed or fasting conditions had a greater impact on substrate oxidation than OC status, and the use of low-dose monophasic combined with OCs did not modify fuel selection and metabolic and hormonal responses during exercise in women.
The effect of a fat-burner and a marine peptide hydrolysate supplement on fat metabolism, during endurance exercise at the Fatmax intensity
Although Thermobol appeared to influence metabolism during submaximal exercise at the Fatmax intensity, Nutripeptin TM did not provide any benefits and was not found to be significantly different across the three experimental conditions.
