a type of muscle fiber used for speed or power activites such as sprinting or weight lifting | fast-twitch muscle fibers |
measured in a laboratory to determine how much oxygen can be used during 1 minute of maximal exercise | aerobic capacity |
indicates how much blood the heart is capable of pumping in exactly 1 minute | cardiac output |

body postures and breathing exercises used to help reduce stress | yoga |
a sequence of carefully performed movements that stretch and strengthen muscles | pilates exercise |
a group of stretching techniques including slow-reversal-hold-relax, contracting-relax, and hold-relax techniques, all of which involve some combination of alternating contraction and relaxation of both agonist and antagonist muscles. | proprioceptive neuromuscular facillatation(PNF) |
technique involving passively stretching a given atnagonist muscle by placing it in s msximal position of stretch and holding it there for an extended time. | static stretching |
technique involving repetitive contractions of the agonist muscle that are used to produce quick stretches of the antagonist muscle | dynamic (ballistic) stretching |
