type of exercise

Sub-maximal

Working below maximal intensity level.

isotonic exercise

activity that combines muscle contraction with repeated movement

isometric exercise

an exercise in which muscles contract but very little body movement takes place

carotid pulse site

at the neck on either side of the trachea

Maximum Heart Rate (MHR)

220-age

target heart rate zone

a heart rate range within which the most gains in cardiorespiratory health will occur

isokinetic exercise

exercise involving muscle contractions with resistance varying at a constant rate
