Kilocalorie
The amount of heat required to raise the temperature of a kilogram (a liter) of water one degree Celsius. The amount of heat needed to raise the temperature of 1 kg of water by 1°C at 1 atmosphere of pressure. The basic unit of energy in the body. The amount of energy required to raise…

Ketosis
A condition in which ketones, or abnormal products of fat metabolism, accumulate in the blood. High concentrations of ketone bodies in the blood. An abnormal increase in ketone production and accumulation in the blood; occurs especially in protein-sparing diets or fasting. An excessive accumulation of ketone bodies caused by accelerated rate of tissue lipolysis. A…

Joint flexibility
Flexibility at a specific joint encompasses all components of the musculoskeletal system and specific neuromuscular pathways of the body.

Isotonic
Muscle actions in which the muscle shortens and lengthens and movement occurs at the joint. Solutions with the same osmotic pressure; often refers to a solution with the same osmotic pressure as body fluids. Hypertonic and hypotonic refer to solutions that are more and less concentrated. A contraction in which a muscle shortens against a…

Isometric
Muscle actions that occur when tension is developed in the muscle without movement at the joint or a change in the muscle length. The tension remains constant because the length of the muscle does not change. Movement against an immovable force; static; a muscle contraction in which the tension increases, but muscle length remains the…
-
Isokinetic
A type of muscular action in which movement occurs at the joint, as in an isotonic action; however, the tension remains constant, as in an isometric action. Contraction in which the tension developed by the muscle while shortening at constant speed is maximal over the full range of motion. In exercise, the term isokinetic is…
