Concepts of Stretching - Test 1

Question 0

Which PNF stretch includes the following movements: opposing muscle contracts to tight muscle to end range, isometric contraction of tight muscle, relax, stretch via unopposed contraction of opposite muscle?

Answer 0

slow-reversal-hold-relax

Question 1

Which neuromuscular organelle would be most affected by a 30 minute prolonged stretch?

Answer 1

Muscle spindles

Question 2

What type of PNF stretching pattern is used when the muscle is contracted towards its shortened end?

Answer 2

Agonistic

Question 3

What is the primary physical property of connective tissue being applied during the following situation: Apply repetitive 30 sec reps of a submaximal passive stretch to create a change in tissue length?

Answer 3

Creep

Question 4

What are the contraindications for stretching?

Answer 4

Acute inflammation in the joint
Fracture
Bony block that restricts motion

Question 5

Which PNF stretching has the following activities: muscle is brought to an end motion, isotonic contraction of tight muscle, relax, passive movement to end-range?

Answer 5

Contract-relax

Question 6

What type of inhibition is used when the opposite muscle is contracted in order to create a better stretch?

Answer 6

Reciprocal inhibition (antagonistic)

Question 7

What percentage of thee 1 RPM is necessary to make muscle endurance gains?

Answer 7

Atleast 66%

Question 8

Describe the overload principle.

Answer 8

Increase in resistance is needed to create additional strength adaptations.

Question 9

What type of activity is throwing a ball?

Answer 9

Open Kinetic Chain

Question 10

Describe the following strength principle: Specific Exercises.

Answer 10

Exercises should mimic stresses placed on the muscle during the athlete’s sport’s functional activities.

Question 11

What are the advantages to open kinetic chain activities in the rehab process?

Answer 11

Usually not delayed because of an athlete being non-weight bearing
Can isolate a weak muscle

Question 12

Describe Isokinetic muscle activity.

Answer 12

Accommodating resistance exercise

Change in resistance through ROM

Question 13

Why is more recovery time necessary for eccentric exercises?

Answer 13

They produce more soreness

Question 14

Define Muscle strength.

Answer 14

Maximal force a muscle or muscle group can exert

Question 15

What co-interventions will make ROM/flexibility technique more effective at changing plastic components of tissue?

Answer 15

Heat

Exercise

Question 16

What is the optimal time for an isometric contraction?

Answer 16

6 seconds

Question 17

What is the appropriate number of reps to best emphasize strength gains?

Answer 17

3-9 reps

Question 18

True or False: Isotonic recovery of muscle strength immediately after the exercise is faster than the isometric recovery.

Answer 18

False

Question 19

Which type of muscle movements are classified as dynamic activities?

Answer 19

Isotonic

Isokinetic
