AEROBIC |
Energy created with oxygen, or in the presence of oxygen. |
AEROBIC SELF TEST |
Any standardized procedure for determining an individual'smaximum oxygen uptake per kilo of body weight. |
AEROBIC STEADY STATE |
A level of metabolism when the oxygen consumption satisfies the energy expenditure and the heart rate required foroxygen transport stabilizes. |
BLOOD PRESSURE |
The pressure of the blood in the blood vessels; usually refering to arterial blood pressure divided into diastolic(the pressure when the heart is at rest between beats) and systolic
(the pressure when the heart is contracting). |
BLOOD SHUNT |
The reduction of the blood volume in the body organs and its movement to the working skeletal muscles. |
BODY FAT |
The total amount of fat in the body. |
CALORIE |
A measure of heat; usually a large calorie (kilocalorie,KC, or C) which is the amount of heat needed to raise the temperature of one kilogram of water one degree Celsius. |
CARBOHYDRATE |
A group of compounds containing carbon, hydrogen, and oxygen; comprising all the sugars (glucose, glycogen, starch, fiber, cellulose, and saccharides). |
COOL-DOWN |
A gradual reduction of activity after vigorous exercise for the purpose of reducing the heart rate back to aresting level, the dissipation of heat, the maintenance of blood flow
, and the recovery of the muscles. |
CORE TEMPERATURE |
The temperature of the deep tissues of the body. |
CRAMP |
An involuntary, spasmodic, painful contraction of a muscleor muscles caused by a strain, heat, and/or electrolyte loss. |
DEHYDRATING |
The reduction of the body water to below the normal level; water output exceeds water intake. |
DURATION |
The amount of time spent exercising in the aerobic state during each exercise session. |
ELECTROLYTES |
A solution that contains ions and can conduct electricity; often the ions of salts such as sodium and chloride. |
FAT |
Triglycerides; a combination, or ester of three fatty acids and glycerol. |
FATIGUE |
A generalized or specific feeling of tiredness that may havea multitude of causes both mental and physical. |
FREQUENCY |
The number of times in a day or a week spent in aerobic exercise. |
FUNCTIONAL CAPACITY |
A quantified comparison of cardiovascular ability by percentage of expected maximum capacity as modified for age, gender and body weight. |
HEART ARRHYTHMIA |
An irregular rhythm or beat of the heart. |
HEAT EXHAUSTION |
Weakness or dizziness caused by overexertion in a hot environment. |
HEAT STROKE |
Elevated body temperature of 106 degrees F. or greater caused by exposure to excessive heat, creating increasedinternal heat production combined with diminished heat loss.
|
HUMIDITY |
A high level of dampness or moisture in the air. |
HYPERHYDRATE |
The practice of increasing the body-water stores by additional fluid consumption prior to intensive prolonged aerobic exercise in a hot environment. |
INTENSITY |
The relative heart rate, speed, or level of exertion expressed as a percentage of the maximum allowable. |
MAXIMUM HEART RATE |
The maximum rate of heart beats per minute acceptable relative to age. |
MAXIMUM INTENSITY |
The maximum exertion level acceptable for an individual during exercise. |
METs |
A measurement unit of energy expenditure; one MET equals approximately 3.5 milligrams of oxygen consumed perminute per kilogram of body weight. |
RATE OF PERCEIVED EXERTION |
A subjective rating on a numerical scale, used to express the perceived difficulty of a given work task. |
RATE OF PROGRESS |
An anticipated amount of improvement over time based upon fitness level and experience level. |
SEDENTARY |
Accustom to sitting; inactive. |
TARGET HEART RATE |
The precise amount of heart beats per minute appropriatefor aerobic conditioning based on age, gender, body weight, and VO2 max. |
TRAINING HEART RATE |
The minimum heart rate required to produce an aerobic steady state. |
TRAINING HEART RATE RANGE |
The range of heart beats per minute appropriate for aerobic conditioning based on age, gender, body weight, and VO2 max. |
VO2 MAX |
The maximum oxygen uptake; measured during exercise and expressed in kilograms per minute. |
WARM-UP |
Low-level exercises used to increase the muscle temperature and/or stretch the muscles prior to strenuous activity. |
WORKLOAD |
The total of resistance as measured by time and/or effort into days, weeks, or months. |
