energy expenditure

what is respiratory exchange ratio?

• Acronym for the ratio of carbon dioxide expired to oxygen consumed at the level of the lungs.

• Acronym for the lowest rate of body metabolism (energy use) that can sustain life.

• A method that gauges the body’s rate and quantity of energy production (calorimetry) by measuring the body’s heat production.

• General sensations of tiredness and accompanying decrements in muscular performance.

what is lactate threshold?

• Acronym for the lowest rate of body metabolism (energy use) that can sustain life.

• A device for measuring the heat produced by the body (or by specific chemical reactions).

• The point during exercise of increasing intensity at which blood lactate begins to accumulate above resting levels, where lactate clearance is no longer able to keep up with lactate production.

• The maximal capacity for oxygen consumption by the body during maximal exertion. It is also known as aerobic power, maximal oxygen intake, maximal oxygen consumption, and cardiorespiratory endurance capacity.

what is basal metabolic rate

• A method of estimating energy expenditure (calorimetry) by measuring respiratory gases.

• A method that gauges the body’s rate and quantity of energy production (calorimetry) by measuring the body’s heat production.

• Acronym for elevated oxygen consumption above resting levels after exercise; at one time referred to as oxygen debt.

• Acronym for the lowest rate of body metabolism (energy use) that can sustain life.

what is direct calorimetry?

• A method of estimating energy expenditure (calorimetry) by measuring respiratory gases.

• A method that gauges the body’s rate and quantity of energy production (calorimetry) by measuring the body’s heat production.

• General sensations of tiredness and accompanying decrements in muscular performance.

• A slow increase in VO2 during prolonged submaximal exercise at a constant power output.

what is maximal oxygen uptake?

• The maximal capacity for oxygen consumption by the body during maximal exertion. It is also known as aerobic power, maximal oxygen intake, maximal oxygen consumption, and cardiorespiratory endurance capacity.

• A device for measuring the heat produced by the body (or by specific chemical reactions).

• Acronym for elevated oxygen consumption above resting levels after exercise; at one time referred to as oxygen debt.

• Acronym for the ratio of carbon dioxide expired to oxygen consumed at the level of the lungs.

what is fatigue?

• General sensations of tiredness and accompanying decrements in muscular performance.

• A method of estimating energy expenditure (calorimetry) by measuring respiratory gases.

• The body’s metabolic rate early in the morning following an overnight fast and 8 hours of sleep. Determining RMR does not require sleeping overnight in a laboratory or clinical facility.

what is resting metabolic rate ?

• General sensations of tiredness and accompanying decrements in muscular performance.

• A device for measuring the heat produced by the body (or by specific chemical reactions).

• The body’s metabolic rate early in the morning following an overnight fast and 8 hours of sleep. Determining RMR does not require sleeping overnight in a laboratory or clinical facility.

what is calorimeter?

• An equation allowing one to calculate the inspired air volume from expired air volume, or expired air volume from inspired air volume.

• A method of estimating energy expenditure (calorimetry) by measuring respiratory gases.

• A device for measuring the heat produced by the body (or by specific chemical reactions).

• A unit of measure of energy in biological systems, where 1.0 calorie is equal to the amount of heat energy needed to raise the temperature of 1.0 g of water 1 °C, from 15 to 16 °C.

what is Indirect calorimetry ?

• The body’s metabolic rate early in the morning following an overnight fast and 8 hours of sleep. Determining RMR does not require sleeping overnight in a laboratory or clinical facility.

• A slow increase in VO2 during prolonged submaximal exercise at a constant power output.

what is Excess postexercise oxygen consumption ?

• A slow increase in VO2 during prolonged submaximal exercise at a constant power output.

• Acronym for elevated oxygen consumption above resting levels after exercise; at one time referred to as oxygen debt.

• The maximal capacity for oxygen consumption by the body during maximal exertion. It is also known as aerobic power, maximal oxygen intake, maximal oxygen consumption, and cardiorespiratory endurance capacity.

• General sensations of tiredness and accompanying decrements in muscular performance.
