Concepts of Stretching - Test 1 Flashcards
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?
slow-reversal-hold-relax
Which neuromuscular organelle would be most affected by a 30 minute prolonged stretch?
Muscle spindles
What type of PNF stretching pattern is used when the muscle is contracted towards its shortened end?
Agonistic
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?
Creep
What are the contraindications for stretching?
Acute inflammation in the joint
Fracture
Bony block that restricts motion
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?
Contract-relax
What type of inhibition is used when the opposite muscle is contracted in order to create a better stretch?
Reciprocal inhibition (antagonistic)
What percentage of thee 1 RPM is necessary to make muscle endurance gains?
Atleast 66%
Describe the overload principle.
Increase in resistance is needed to create additional strength adaptations.
What type of activity is throwing a ball?
Open Kinetic Chain
Describe the following strength principle: Specific Exercises.
Exercises should mimic stresses placed on the muscle during the athlete’s sport’s functional activities.
What are the advantages to open kinetic chain activities in the rehab process?
Usually not delayed because of an athlete being non-weight bearing
Can isolate a weak muscle
Describe Isokinetic muscle activity.
Accommodating resistance exercise
Change in resistance through ROM
Why is more recovery time necessary for eccentric exercises?
They produce more soreness
Define Muscle strength.
Maximal force a muscle or muscle group can exert
What co-interventions will make ROM/flexibility technique more effective at changing plastic components of tissue?
Heat
Exercise
What is the optimal time for an isometric contraction?
6 seconds
What is the appropriate number of reps to best emphasize strength gains?
3-9 reps
True or False: Isotonic recovery of muscle strength immediately after the exercise is faster than the isometric recovery.
False
Which type of muscle movements are classified as dynamic activities?
Isotonic
Isokinetic
