Muscle reflexes

What is the primary function of muscle spindles?

• To facilitate tendon relaxation

• To sense muscle stretch

• To sense muscle tension

• To inhibit muscle contraction

Which structure is responsible for autogenic inhibition?

• Golgi tendon organs

• Myosin fibers

• Muscle spindles

• Actin fibers

What happens during reciprocal inhibition?

• The agonist muscle is inhibited

• The tendon is relaxed

• The antagonist muscle is inhibited

• The muscle fibers are lengthened

In the patellar tendon reflex, which muscle is activated?

• Hamstring

• Quadricep

• Gastrocnemius

• Bicep

What is the role of the Golgi tendon organ during a one rep max back squat?

• To activate the antagonist muscle

• To decrease muscle contraction

• To stretch the muscle

• To increase muscle contraction

How can the Golgi tendon organ response be dampened?

• By reducing muscle tension

• By performing low-intensity exercises

• By consistently training at high loads

• By increasing muscle stretch

What is the effect of improved motor pattern efficiency?

• Increased antagonist co-activation

• Increased muscle tension

• Decreased agonist activation

• Reduced antagonist co-activation

Why does co-activation around joints increase with age?

• Due to decreased muscle strength

• Due to increased need for joint stability

• Due to increased muscle flexibility

• Due to decreased tendon elasticity

What is the primary purpose of reciprocal inhibition during a quick movement?

• To increase muscle tension

• To activate the antagonist muscle

• To protect the joint from overstretching

• To decrease muscle flexibility

What happens to the Golgi tendon organ response with chronic high-load training?

• It becomes more sensitive

• It becomes less sensitive

• It remains unchanged

• It increases muscle tension
