the rate of speed of music, usually expressed in beats per minute.

Question 25

Musical Phrase

Answer 25

a short musical passage; used as a means of choreographing movement to a piece of music.

Question 26

Dyspnea scale

Answer 26

a subjective 4-point scale that reflects an individual's perception of the difficulty of breathing during physical activity with 1 reflecting mild difficulty and 4 reflecting severe difficulty that forces the individual to stop exercising.

Question 27

Pulse rate

Answer 27

the wave of pressure in the arteries that occurs each time the heart beats.

Question 28

Steady-state exercise

Answer 28

a state of aerobic exercise in which the intensity remains consistent, as opposed to alternating between higher and lower intensities.

Question 29

Maximal heart rate (MHR)

Answer 29

the highest rate a person can attain; HRmax

Question 30

Electrocardiogram (ECG or EKG)

Answer 30

a recording of the electrical activity of the heart.

Question 31

Heart-rate reserve (HRR)

Answer 31

to reserve capacity of the heart; the difference between maximal heart rate and resting heart rate. It reflects the heart's ability to increase the rate of beating and cardiac output above resting level to maximum intensity.

Question 32

Resting heart rate (RHR)

Answer 32

the number of beats per minute when the body is at rest. Usually counted the first thing in the morning before any physical activity.

Question 33

Answer 34

considered the best indicator of cardiovascular endurance. It is the maximum amount of oxygen (mL) that a person can use in one minute per kilogram of body weight. Also called maximal oxygen uptake and maximal aerobic capacity.

Question 35

VO2 reserve (VO2r)

Answer 35

the difference between VO2max and VO2 at rest; used for programming aerobic exercise intensity

Dyspnea

Answer 36

shortness of breath; a subjective difficulty or distress in breathing.

Question 37

Emphysema

Answer 37

an obstructive pulmonary disease characterized by the gradual destruction of the lung alveoli and the surrounding connective tissue, in addition to airway inflammation, leading to reduced ability to effectively inhale and exhale.
