Question 1

During a running gait cycle, which phase is associated with the greatest ground reaction force?

Accepted Answer

Initial contact (heel strike)

Answer

Initial contact produces the first peak ground reaction force, often 1.5–2× body weight during running.

Question 2

The Q-angle is formed between the line of pull of the quadriceps and the patellar tendon; an elevated Q-angle in female athletes increases risk of:

Accepted Answer

ACL injury and patellofemoral pain syndrome

Answer

A wider Q-angle increases valgus stress at the knee, predisposing athletes to ACL injury and patellofemoral tracking problems.

Question 3

Which term describes the tendency of a joint to return to its resting position after being displaced, related to passive soft-tissue stiffness?

Accepted Answer

Laxity

Answer

Laxity refers to the amount of passive joint displacement possible; high laxity means the joint moves far before restraint builds.

Question 4

A gymnast performs a back handspring. The wrist is loaded in which primary direction during the push-off phase?

Accepted Answer

Dorsiflexion and axial compression

Answer

During push-off the wrist bears compressive load while positioned in dorsiflexion, stressing the distal radius and scaphoid.

Question 5

The stretch-shortening cycle (SSC) improves power output primarily because:

Accepted Answer

Elastic energy stored in tendons is released during the concentric phase

Answer

Tendons and series elastic components store elastic potential energy during the eccentric (pre-stretch) phase and release it in the subsequent concentric contraction.
