Introduction
Throughout the day, humans expend energy through a variety of different processes and activities. The body's response to this energy demand is energy intake in the form of different fuel sources which includes carbohydrates, proteins, lipids and although it is not an optimal fuel source, humans are also capable of using alcohol for energy. After the food is ingested, it is digested through complex processes that breakdown the larger molecules into smaller molecules such as glucose/fructose, amino acids as well as triglycerides and free fatty acids (FFA). Once broken down, the molecules are absorbed into the bloodstream so that they can be used or stored. Cells can metabolize these molecules through a combustion process called …show more content…
For example, energy intake can affect the type of fuel sources available which will play a role in determining energy pathway is used. Energy expenditure can also have an impact on energy intake because a person, such as an athlete, who increases their energy output though physical activity will require a greater energy intake to meet these demands. This relationship is also highly dependent on a number of factors. The first being that athletes who compete in endurance type sports need to adapt their energy intake differently compared to athletes who compete in power sports as a result of the different requirements in energy expenditure. Other factors that influence this relationship is the environment in which the athletes train and compete. More specifically, how the relationship changes when an athlete competes in the heat versus the cold. The purpose of this paper is to determine and understand how these factors influence the relationship between energy intake and energy expenditures. Understanding these concepts can be highly beneficial for athletes, especially elite athletes, because it can help them modify energy intake and expenditure to optimize their training and their sport …show more content…
There has also been evidence that combining carbohydrate and protein intake during the recovery following a résistance training session can speed up recovery which is useful for athletes such as sprinters and weightlifters especially when they compete more than once throughout the day and require a fast recovery (Alghannham, 2011). Furthermore, researchers Slater and Phillips (2011) explained that power athletes will typically have a greater energy intake compared to endurance athletes due to a larger lean body mass however the most important aspect of a power athlete's energy intake is timing. It is important to ingest carbohydrates before résistance training in order to optimize work capacity during the workout and to co-ingest carbohydrates and proteins after a training session to promote muscle protein metabolism as well as accelerate the restoration of glycogen
