Question 1

An athlete returns from an ACL reconstruction at 6 months post-op. Which criterion is most critical before clearing them for full sport return?

Accepted Answer

Limb symmetry index ≥90% on hop tests

Answer

A limb symmetry index ≥90% on functional hop tests is a key evidence-based criterion indicating adequate neuromuscular function for safe sport return.

Question 2

Which exercise modification is most appropriate for a client with osteoporosis performing resistance training?

Accepted Answer

Avoid high-impact twisting and spinal flexion under load

Answer

High-impact torsional forces and loaded spinal flexion pose the greatest vertebral fracture risk in osteoporotic individuals.

Question 3

Relative Energy Deficiency in Sport (RED-S) in female athletes is most directly caused by:

Accepted Answer

Low energy availability relative to exercise energy expenditure

Answer

RED-S occurs when energy intake fails to cover both resting metabolic needs and exercise expenditure, creating a deficit that disrupts hormonal and physiological function.

Question 4

When programming for an athlete with shoulder impingement syndrome, which exercise should be avoided initially?

Accepted Answer

Overhead pressing movements

Answer

Overhead pressing narrows the subacromial space and compresses the impinged structures, exacerbating symptoms during the acute phase.

Question 5

A master athlete (age 58) shows significantly longer recovery times after intense training. The primary physiological reason is:

Accepted Answer

Decreased muscle protein synthesis rate and hormonal anabolic response

Answer

Aging blunts the anabolic hormonal response (GH, IGF-1, testosterone) and slows muscle protein synthesis, extending the time needed for tissue repair.
