Question 1

Wolff's Law applied to sport rehabilitation states that bone remodels:

Accepted Answer

Along lines of mechanical stress, strengthening under load and weakening without it

Answer

Wolff's Law holds that bone architecture adapts to the direction and magnitude of mechanical forces applied to it.

Question 2

The Thomas test assesses flexibility of which muscle group, and a positive result indicates what biomechanical consequence?

Accepted Answer

Hip flexors (iliopsoas/rectus femoris); anterior pelvic tilt and increased lumbar lordosis

Answer

A positive Thomas test (thigh rises off table) indicates hip flexor tightness, which anteriorly tilts the pelvis and increases lumbar lordosis during sport.

Question 3

In swimming freestyle stroke, internal impingement of the shoulder most commonly occurs during which phase?

Accepted Answer

Recovery

Answer

During the recovery phase the arm is elevated and internally rotated, placing the greater tuberosity against the posterior superior glenoid labrum (internal impingement).

Question 4

Myofascial continuity in the posterior kinetic chain (superficial back line) means that plantar fascia tension can directly affect:

Accepted Answer

Hamstring length and lumbar erector tone

Answer

The superficial back line connects plantar fascia through the gastrocnemius, hamstrings, and sacrotuberous ligament to the lumbar erectors, so foot mechanics influence the entire posterior chain.

Question 5

An athlete exhibits excessive foot pronation during running. Which compensatory motion at the knee is most likely?

Accepted Answer

Increased knee valgus and tibial internal rotation

Answer

Subtalar pronation is coupled with tibial internal rotation, which rotates the femur medially and increases dynamic knee valgus.
