USTA Injury Prevention & Rehabilitation 3 — Questions and Answers
Question 1: A coach notices a player externally rotating the front foot excessively during groundstrokes. Which injury risk does this most directly increase?
- Achilles tendon rupture
- Medial knee stress from valgus collapse (Correct answer)
- Shoulder impingement
- Wrist ulnar deviation strain
Correct answer: Medial knee stress from valgus collapse
Excessive front-foot external rotation can contribute to valgus knee collapse, placing stress on medial knee structures including the MCL and medial meniscus.
Question 2: Which shoulder condition in overhead athletes involves compression of the supraspinatus tendon and subacromial bursa?
- Acromioclavicular joint sprain
- Subacromial impingement syndrome (Correct answer)
- Posterior labral tear
- Biceps tenodesis
Correct answer: Subacromial impingement syndrome
Subacromial impingement involves pinching of the supraspinatus and bursa between the humeral head and acromion during arm elevation.
Question 3: What is the primary purpose of a functional movement screen (FMS) or movement assessment before a tennis season?
- To determine a player's aerobic capacity
- To identify asymmetries and movement deficiencies that predict injury risk (Correct answer)
- To measure racket head speed during serves
- To evaluate mental focus and competitive mindset
Correct answer: To identify asymmetries and movement deficiencies that predict injury risk
A movement screen identifies dysfunctional movement patterns and asymmetries that, if unaddressed, can predispose athletes to musculoskeletal injuries.
Question 4: A 14-year-old tennis player is experiencing elbow pain on the medial side during and after heavy topspin forehand practice. The most likely concern is:
- Lateral epicondylitis
- Little Leaguer's elbow (medial apophysitis) (Correct answer)
- Olecranon bursitis
- Radial nerve entrapment
Correct answer: Little Leaguer's elbow (medial apophysitis)
Medial apophysitis (Little Leaguer's elbow) is common in skeletally immature athletes and involves stress at the medial epicondyle growth plate from valgus loading.
Question 5: Which of the following is the most effective long-term strategy for managing chronic patellar tendinopathy in a tennis player?
- Complete rest until pain resolves
- Corticosteroid injections every six weeks
- Progressive heavy slow resistance eccentric loading of the quadriceps (Correct answer)
- Avoiding all lower-body exercises indefinitely
Correct answer: Progressive heavy slow resistance eccentric loading of the quadriceps
Evidence supports heavy slow resistance training, particularly eccentric exercises such as decline squats, as the most effective long-term treatment for patellar tendinopathy.
Question 6: A player returns to training two weeks after an ankle sprain but still shows fear of re-injury during lateral movements. What should the rehabilitation focus include at this stage?
- Only passive range-of-motion exercises
- Progressive sport-specific proprioception and confidence-building drills (Correct answer)
- Complete immobilization for another four weeks
- Maximum-intensity sprint training
Correct answer: Progressive sport-specific proprioception and confidence-building drills
Proprioceptive training restores neuromuscular control, and sport-specific progression addresses both physical readiness and psychological confidence for return to play.
Question 7: Which of the following best describes the role of adequate sleep in injury prevention for competitive tennis players?
- Sleep duration has no measurable effect on injury rates
- Sleep supports tissue repair, hormonal balance, and neuromuscular recovery, reducing injury risk (Correct answer)
- Only elite professionals need to monitor sleep; juniors are unaffected
- More than 7 hours of sleep reduces performance by causing excessive fatigue
Correct answer: Sleep supports tissue repair, hormonal balance, and neuromuscular recovery, reducing injury risk
Adequate sleep (7–9 hours) is essential for growth hormone release, tissue repair, and cognitive-motor recovery, all of which are directly linked to reduced injury rates.
