Chapter 4 review SM 1

Hopping, bounding and depth jumps are forms of:

• isokinectic

• plyometric

• isotonic

• circuit

The ability of a muscle group to exert force rapidly is called:

• muscle endurance

• muscle power

• muscle strength

• muscle torque

An exercise performed by doing a maximal eccentric stretch immediately preceding a concentric contraction is called:

• free exercise

• calisthenics

• plyometrics

• isotonic

Which of the following stretching techniques is capable of producing the most dramatic increases in flexibility?

• PNF

• static

• dynamic

• none of the above

When a sprinter runs the 50 yard dash what structure within the muscle is primarily being used?

• muscle spindles

• golgi tendon organs

• fast twitch

• slow twitch

If the intensity of an activity is such that sufficient oxygen can be supplied to meet the demands of working tissues, the activity is:

• aerobic

• anaerobic

• isotonic

• isometric

Continuous training involves four considerations: the mode, the frequency, the duration, and the intensity of exercise.

• true

• false

A concentric or negative contraction occurs in the biceps as the weight is lowered during a biceps curl.

• true

• false

The type of muscle contraction where the muscle tenses but does not shorten.  

• Isometric
• Isotonic
• Contraction
• relaxation

As the athlete lowers the weights, his biceps undergo-

• isometric concentric contraction
• isotonic eccentric contraction
• isometric contraction
