Overactive / Underactive muscles - reversed

Question 1

A state of having disrupted neuromuscular recruitment patterns that lead a muscle to be more active during a joint action&raquo_space; shortened / tight / strong

Answer 1

Overactive muscle

Question 2

A state of having disrupted neuromuscular recruitment patterns that lead a muscle to be relatively less active during a joint action&raquo_space; lengthened / weak / inhibited

Answer 2

Underactive muscle

Question 3

the alteration of muscle length surrounding a joint.
Think of it like a Tug-of-War between opposing muscles (agonist / antagonist). The overactive (strong) muscle wins and pulls the limb or body part into an altered (unwanted) position

Answer 3

Muscle imbalance

Question 4

The resting length of a muscle and the tension the muscle can produce at that resting length

Answer 4

Length-tension relationship

Question 5

Process by which an overactive muscle (shortened, tight, and strong), and/or myofascial adhesions in the muscle cause decreased neural drive of its function antagonist&raquo_space; example: Tight hip flexors decrease neural drive to the gluteus maximus inhibiting its function. This causes synergistic dominance where the synergist (hamstrings) take over to perform the movement.

Answer 5

Altered reciprocal inhibition (altered length-tension)

Question 6

When synergists take over function for an underactive (lengthened, inhibited, and weak) prime movers

Answer 6

Synergistic dominance (altered force-couples)

Question 7

1. Feet/ankles
2. Knees
3. Hips
4. Shoulders
5. Head/neck

Answer 7

5 kinetic chain checkpoints

Question 8

Foam-rolling inhibits the muscle and breaks up any tension and adhesions in the fascia that may be present. Static stretching will lengthen shortened muscles.

Answer 8

we want to inhibit and lengthen overactive muscles by using SMR techniques

Question 9

Performing isolated exercises that target the specific muscles that are weakened and elongated will strengthen them and bring the length-tension relationship back into alignment.

Answer 9

we want to strengthen underactive muscles by performing isolated exercises.
