Absolute Strength
The maximum amount a person can lift in one repetition.
Active Stretch
Muscles are stretched using the contraction of the opposing muscle, (antagonist). For an example stretching the triceps, requires the biceps to contract.
Additives (food additives) Any natural or synthetic substance that is added to a food item, thus changing the final product. Additives are used to maximize the efficiency of products during their production, packaging, and transportation. They are also commonly used to prolong a products shelf life.
Adrenals Adrenals are the glands that produce stress-related hormones like cortisol, adrenaline and DHEA. Since overly active stress-hormones can contribute to weight gain- especially around the abdomen, these glands play an important role in weight loss.
Adduction
Movement of a limb toward middle of body, such as bringing arms to side from extended position at shoulder.
Adhesion
Fibrous patch holding muscles or other parts together that are normally separated.
ADP (Adenosine Diphospahate)
ADP is formed when ATP is broken down within the bodies cell furnace, (the mitochondria). This provides energy for muscular contraction.
Aerobic capacity
Another term for maximal oxygen uptake (VO2 Max)Your aerobic capacity is a measure of your body's ability to deliver oxygen to your muscles, as well as how much of that oxygen your muscles can use for energy. In other words, aerobic capacity is how much oxygen your body can process when you're working out as hard as you can. Regular exercise can increase your aerobic capacity. Aerobic Exercise, (with oxygen)
Activity in which the body is able to supply adequate oxygen to the working muscles, for a period of time. Running, cross-country skiing and cycling are examples of aerobic activities.
Agonist
Muscle directly engaged in contraction that is primarily responsible for movement of a body part.
