As the level of intensity of exercise increases, the body reaches a point where the level of oxygen within the cell’s mitochondria is not sufficient. Since there is not enough available oxygen, the pyruvate produced by glycolysis cannot be oxidized. Furthermore, since energy production must continue, ATP production from glycolysis must increase.
Building Blocks There is no need to fear the c-word! Carbohydrates are the body’s primary source of energy, and the brain relies exclusively on them. The majority of calories in an athlete’s diet should be coming from healthy sources of carbohydrates. The most important thing is to be able to identify which carbs are healthy […]
What Is A Calorie? Technically, a calorie is a measure of heat or unit of energy, but to the human body, calories keep everything going. Every bodily function from heartbeats to muscle contractions requires calories. The body needs a certain amount of calories per day from food to operate. Through the processes of digestion, absorption […]
Defining Sports Nutrition Most athletes and active individuals understand that nutrition is important for a healthy body. What most of them do not realize is that nutrition directly affects how they perform. Learning what, how, and when to eat can be what makes or breaks performance. The outcome can be a desired edge that sets […]
Most cells, including muscle cells, contain structures called mitochondria. The mitochondria are the sites of cellular aerobic energy production (also known as cellular respiration, aerobic oxidation and oxidative phosphorylation). Larger numbers of mitochondria in a cell lead to a greater capability for aerobic energy production. Therefore, cells with larger numbers of mitochondria have a greater […]
