SM Ch 7

Adaptation

• The ability of a joint to move freely through its full range of motion.

• Weakness and wasting away of muscle tissue.

• The systematic application of exercise stress sufficient to stimulate muscle fatigue, but not so severe that breakdown and injury occur.

• An activity that puts increased demand on the lungs, heart, and other body systems; also known as aerobic or endurance training.

Atrophy

• A type of exercise in which a machine is used to control the speed of contraction within the range of motion.

• An increase in the size of muscle tissue.

• An activity that causes the muscle to contract and shorten.

• Weakness and wasting away of muscle tissue.

ballistic stretching

• A rhythmical, bouncing action that stretches the muscles a little further each time. Once a popular technique, this form of stretching is rarely used today. Especially when the muscles are cold, ballistic stretching was responsible for increased injuries.

• The ability of a joint to move freely through its full range of motion.

• Fiber in a motor unit that produces quick and forceful contractions; these fibers are easily fatigued.

• A form of dynamic exercise accomplished utilizing a training partner.

cardiorespiratory conditioning

• Fiber in a motor unit that produces quick and forceful contractions; these fibers are easily fatigued.

• A type of exercise in which a machine is used to control the speed of contraction within the range of motion.

• An activity that causes the muscle to contract and shorten.

• An activity that puts increased demand on the lungs, heart, and other body systems; also known as aerobic or endurance training.

circuit training

• A type of exercise in which a machine is used to control the speed of contraction within the range of motion.

• The use of 6 to 10 strength exercises completed one right after another; each exercise is performed for a specific number of repetitions or period of time before moving to the next exercise.

• A form of dynamic exercise accomplished utilizing a training partner.

• An activity that causes tension in the muscle to increase but does not cause the muscle to shorten.

dynamic (isotonic) exercise

• An activity that causes the muscle to contract and shorten.

• A type of exercise in which a machine is used to control the speed of contraction within the range of motion.

• An activity that causes tension in the muscle to increase but does not cause the muscle to shorten.

• A form of dynamic exercise accomplished utilizing a training partner.

fast-twitch fiber

• An increase in the size of muscle tissue.

• Weakness and wasting away of muscle tissue.

• Fiber in a motor unit that produces quick and forceful contractions; these fibers are easily fatigued.

• The systematic application of exercise stress sufficient to stimulate muscle fatigue, but not so severe that breakdown and injury occur.

flexibility

• The ability of a joint to move freely through its full range of motion.

• A rhythmical, bouncing action that stretches the muscles a little further each time. Once a popular technique, this form of stretching is rarely used today. Especially when the muscles are cold, ballistic stretching was responsible for increased injuries.

• An activity that causes the muscle to contract and shorten.

• A form of dynamic exercise accomplished utilizing a training partner.

hypertrophy

• An increase in the size of muscle tissue.

• Weakness and wasting away of muscle tissue.

isokinetic exercise

• An activity that causes tension in the muscle to increase but does not cause the muscle to shorten.

• A type of exercise in which a machine is used to control the speed of contraction within the range of motion.

• A form of dynamic exercise accomplished utilizing a training partner.
