The region of the sarcomere where myosin filaments are predominantly seen with minor overlap of the actin filaments.
Adenosine Diphosphate (ADP)
A high-energy compound occurring in all cells from which adenosine triphosphate (ATP) is formed.
Adenosine Triphosphate (ATP)
Energy storage and transfer unit within the cells of the body.
The breakdown of triglycerides into smaller subunits called free fatty acids (FFAs) to convert FFAs into acyl-CoA molecules, which then are available to enter the Krebs cycle and ultimately lead to the production of additional ATP.
Three main pathways used by the kinetic chain to produce ATP.
The study of energy in the human body.
1. Organic compounds of carbon, hydrogen, and oxygen, which include starches, cellulose, and sugars, and are an important source of energy. All carbohydrates are eventually broken down in the body to glucose, a simple sugar. 2. Neutral compounds of carbon, hydrogen, and oxygen (such as sugars, starches, and celluloses), which make up a large portion of animal foods.
The capacity to do work.
A condition of balance between opposed forces, influences, or actions.
Excess Postexercise Oxygen Consumption (EPOC)
The state in which the body's metabolism is elevated after exercise.
The examination of bioenergetics as it relates to the unique physiologic changes and demands placed on the body during exercise.
One of the three main classes of foods and a source of energy in the body. Fats help the body use some vitamins and keep the skin healthy. They also serve as energy stores for the body. In food, there are two types of fats, saturated and unsaturated.
The formation of glucose from noncarbohydrate sources, such as amino acids.
A simple sugar manufactured by the body from carbohydrates, fat, and to a lesser extent protein, which serves as the body's main source of fuel.
The complex carbohydrate molecule used to store carbohydrates in the liver and muscle cells. When carbohydrate energy is needed, glycogen is converted into glucose for use by the muscle cells.
The area of the sarcomere where only myosin filaments are present.
The area of the sarcomere where only actin filaments are present.
The part of a muscle by which it is attached to the part to be moved—compare with origin.
An acid produced by glucose-burning cells when these cells have an insufficient supply of oxygen.
All of the chemical reactions that occur in the body to maintain itself. Metabolism is the process in which nutrients are acquired, transported, used, and disposed of by the body.
Amino acids linked by peptide bonds, which consist of carbon, hydrogen, nitrogen, oxygen, and usually sulfur, and that have several essential biologic compounds.
A byproduct of anaerobic glycolysis.
The material or substance on which an enzyme acts.
The chemical or substrate form in which most fat exists in food as well as in the body
