demand

1. The electric load on a system, integrated over a specific time interval; usually expressed in watts or kilowatts.
2. The volume of gas per unit time (usually expressed in cubic feet per hour or liters per second) or the amount of heat (usually expressed in Btu per hour or megajoules per hour) required for the operation of one or more gas appliances.
3. The rate of flow of water, usually expressed in gallons per minute (liters per second), furnished by a water supply system to various types of plumbing fixtures and water outlets under normal conditions.

FA uptake in the muscle is dependent on metabolic demands and lipid availability.
Hypothetically, such inherent error in the calculations could have a high impact on exercise prescription and expose the animals to unnecessary risk due to prolonged metabolic demand and physiological stress.
The single ACC sensor provided inappropriate rates at most stages of the treadmill exercise test except during the 1 [sup]st min, after which the adaption was almost totally opposite to the SN and body metabolic demands. This result reflects the major disadvantage of activity-based sensor systems which are nonphysiologic [sup][9] and hardly distinguish between mild and vigorous physical activities, and are unable to provide a sustained rate increase in response to an oxygen debt after long exercise.
Therefore, the purpose of this study was to compare metabolic demand between young, highly active individuals who had sustained traumatic unilateral TTA and nondisabled controls.
In this way, blood lactate concentration ([La]) has a remarkable importance for the knowledge of the metabolic demands on the lifeguards in situ to allow coaches to effectively structure training programs (14) and recovery strategies during saving and training (15).
* Adequate analgesia and sedation reduce agitation, Valsalva and metabolic demand.
ICP remains relatively constant, between five and 15mmHg, despite changes in blood and CSF flow related to posture, exercise and metabolic demand. The brain tissue is relatively incompressible, so first CSF and then blood flow are altered when ICP increases.
The reason for this greater amount of fat loss is due to a continued higher metabolic demand placed on the body after intense exercise for slow, boring cardio it may only take several minutes for the metabolism to recover back to pre exercise levels.
There can be several reasons for this, including increased metabolic demand, diseases, insufficient dietary CoQ10 intake, deficiency of factors required for biosynthesis, gene mutation and oxidative insult.
Patients who are malnourished are already in a situation in which they are likely to develop the complications of malnutrition and therefore require active nutritional support without further delay, whereas patients at risk of malnutrition may become malnourished over the next few days unless their disease process improves so that metabolic demand decreases and oral nutritional intake increases, or active steps are taken to ensure that their nutritional intake meets their ongoing metabolic demands.
Both the brain and heart are highly vulnerable because of their high oxygen consumption, but the brain is especially sensitive for two reasons: first, neural cell membrane lipids are high in oxidizable polyunsaturated fatty acids (Gupta 2004); second, the developing brain has an increased metabolic demand associated with its perinatal growth spurt, during which it has lower reserves of protective enzymes and antioxidants (James et al.
The brain is not able to meet normal metabolic demands, let alone an increase in metabolic demand.
