As a professional soccer player your cardiovascular and cardiorespiratory endurance is almostimpeccable. With that said, “exercise improves the capacity of muscle to oxidize or burn fat” (Edward L. Melanson, 2009). It is possible for your body to utilize fat as an energy source but the percentage in comparison to superior energy stores is low. Scientific research supports that “intramuscular triglyceride (IMTG) may provide up to 10% of total energy expenditure during prolonged exercise” Edward L. Melanson, 2009). Protein is metabolized for energy when the body does not have enough carbohydrates and healthy fat to utilize (Sandi Busch, 2016). The “amino acids derived are converted into glucose and used for energy. On the flipside, if the protein you consume contributes excess calories, the amino acids can be stored as fat” (Sandi Busch, 2016). When not converted to energy, protein serves as the building block for muscle repair and growth with direct correlation to exercise. The chief source of energy in the body should always come from carbohydrates. “Dietary carbohydrate intake has a large influence on fat mobilization and oxidation during exercise; when dietary carbohydrate produces sufficient carbohydrate reserves in the body, carbohydrate becomes the preferred fuel during exercise. This is especially important during intense exercise because only carbohydrate(not fat) can be mobilized and oxidized rapidly enough to meet the energy requirements for intense muscular contractions” (Edward F. Coyle, 1995).
