NSCA CSCS Injury Prevention 2

Question 1

Which landing mechanics strategy is most effective for reducing ACL injury risk during deceleration tasks?

Accepted Answer

Landing with hip and knee flexion greater than 30° and soft knee bend

Answer

Landing with hip and knee flexion >30° and a soft knee reduces peak ground reaction forces and ACL strain.

Question 2

An athlete reports anterior knee pain worsening during downhill running. Which structure is most likely overloaded?

Accepted Answer

Patellar tendon and patellofemoral joint

Answer

Downhill running increases compressive patellofemoral forces, stressing the patellar tendon and cartilage.

Question 3

What is the PRIMARY role of eccentric hamstring strength in injury prevention?

Accepted Answer

Decelerating knee extension and protecting the ACL

Answer

Eccentric hamstring strength decelerates rapid knee extension, reducing ACL loading during high-speed movements.

Question 4

Which training modification best reduces overuse injury risk when introducing a new running program?

Accepted Answer

Increasing weekly mileage by no more than 10% per week

Answer

The 10% rule limits cumulative load increases to allow musculoskeletal tissue adaptation and prevent overuse injuries.

Question 5

A basketball player exhibits excessive forward trunk lean and knee valgus during jump landing. Which muscle group weakness is most implicated?

Accepted Answer

Hip abductors and external rotators

Answer

Weak hip abductors and external rotators fail to control femoral adduction/internal rotation, causing knee valgus on landing.
