Which of the following statements is TRUE about functional fitness?

• It is important for the performance of daily activities

• It is a joint-specific indicator of flexibility

• It is strongly linked to overall aerobic conditioning

• It is strongly linked to genetics and can't be easily changed

Use of force or gravity to aid in stretching is characteristic of:

• static stretching

• dynamic stretching

• ballistic stretching

• passive assistance

Which of the following statements about ballistic stretching is TRUE?

• Ballistic stretching is considered to be safer than static stretching.

• Ballistic stretching causes hypermobility.

• Ballistic stretching is a specific type of dynamic stretching.

• Ballistic stretching is more effective than PNF stretching.

The muscle being stretched is known as the:

• trigger point

• antagonist

• agonist

• ballistic muscle

The type of stretching exercise believed to be most effective at improving flexibility is

• static

• static passive

• PNF

• dynamic

The recommended intensity for a safe and effective stretch is:

• up to the point of extreme pain.

• 10 percent beyond the normal length of the muscle.

• 50 percent beyond the normal length of the muscle.

• twice the normal length of the muscle.

Which of the following statements is TRUE about stretching?

• Too much flexibility can increase risk for injuries.

• Some stretching should always be done before exercise.

• Stretching before exercise reduces the risks for musculotendinous injuries.

• Stretching is not effective for treatment of musculoskeletal pain.

What factors influence the amount of motion specific to a given joint?

• bone density and shape of the joint surfaces

• extensibility of the ligaments and shape of the joint surfaces

• tautness of the ligaments and bone density

• bone density and joint size

What is flexibility?

• the length of muscle around a joint

• the range of motion in a joint or joints

• the shape of bones and cartilage in the joint

• the number of muscles, tendons, ligaments, and fascia that cross the joint

With regard to flexibility,

• maximum flexibility peaks during adolescence.

• physical inactivity can contribute to poor flexibility.

• it can be assessed to determine a person's health status.

• a person with adequate flexibility in the legs is also likely to have good arm flexibility.
