SCS Flexibility & Mobility Training 4

Question 1

Foam rolling (self-myofascial release) is thought to improve tissue extensibility primarily by:

Accepted Answer

Reducing neural tension and fascial adhesions through autogenic inhibition

Answer

SMR is believed to reduce neural tone via autogenic inhibition and mechanically break down fascial adhesions, temporarily improving extensibility.

Question 2

Which mobility drill most specifically targets hip internal rotation in athletes?

Accepted Answer

90/90 hip switch seated on the floor

Answer

The 90/90 hip switch drill places one hip in internal rotation and one in external rotation, directly training internal rotation range and control.

Question 3

What does the term 'hypermobility' indicate in a clinical sport context, and why is it a concern?

Accepted Answer

Hypermobility is excessive joint laxity that can reduce stability and increase injury risk

Answer

Hypermobility denotes excessive joint range of motion due to ligamentous laxity, which can compromise joint stability and predispose athletes to sprains and dislocations.

Question 4

A strength and conditioning specialist notices an athlete's lumbar spine excessively flattens (posterior pelvic tilt) at the bottom of a squat. Which mobility limitation is most likely contributing?

Accepted Answer

Restricted hip flexion mobility (butt wink)

Answer

The 'butt wink' (posterior pelvic tilt in deep squat) is commonly caused by limited hip flexion mobility that forces the pelvis to rotate under the spine.

Question 5

Which parameter most determines the effectiveness of a static stretch in producing lasting ROM increases?

Accepted Answer

Total accumulated time under stretch (volume)

Answer

Research indicates that total accumulated stretch time (e.g., 2 minutes per muscle) is the primary determinant of chronic ROM improvements from static stretching.
