ITF Injury Prevention 3 — Questions and Answers
Question 1: Which on-court surface is associated with the highest risk of knee injuries due to increased rotational friction?
- Clay
- Grass
- Hard court (acrylic) (Correct answer)
- Carpet
Correct answer: Hard court (acrylic)
Hard court acrylic surfaces have high friction coefficients that increase rotational stress on the knee during pivoting and direction changes.
Question 2: The term 'tennis elbow' clinically refers to which condition?
- Medial epicondylitis
- Lateral epicondylitis (Correct answer)
- Olecranon bursitis
- Cubital tunnel syndrome
Correct answer: Lateral epicondylitis
Tennis elbow is lateral epicondylitis, involving microtears at the origin of the wrist extensor muscles on the lateral epicondyle of the humerus.
Question 3: Which footwear feature is most important for preventing ankle injuries on clay courts?
- A herringbone outsole pattern (Correct answer)
- A flat rubber outsole
- Carbon fiber midsole plate
- High-top ankle collar
Correct answer: A herringbone outsole pattern
A herringbone outsole allows controlled sliding on clay while providing enough traction to prevent excessive ankle inversion that leads to sprains.
Question 4: Scapular dyskinesis in tennis players is best corrected by strengthening which muscles?
- Pectoralis major and anterior deltoid
- Lower trapezius and serratus anterior (Correct answer)
- Biceps brachii and coracobrachialis
- Infraspinatus and subscapularis only
Correct answer: Lower trapezius and serratus anterior
The lower trapezius and serratus anterior are the primary scapular stabilizers; their weakness leads to dyskinesis that increases shoulder injury risk.
Question 5: What is the primary purpose of an ITF-certified coach conducting a pre-participation physical screening?
- To set ranking goals for the player
- To identify risk factors and movement deficiencies before training begins (Correct answer)
- To determine racket grip size
- To assess tactical decision-making
Correct answer: To identify risk factors and movement deficiencies before training begins
Pre-participation screening identifies musculoskeletal imbalances, movement deficiencies, and prior injury history so coaches can individualize injury prevention programs.
Question 6: Which early symptom should prompt a tennis coach to immediately remove a player from heat conditions?
- Mild thirst
- Cessation of sweating with confusion (Correct answer)
- Light muscle soreness
- Slight increase in heart rate
Correct answer: Cessation of sweating with confusion
Cessation of sweating combined with confusion indicates heat stroke, a life-threatening emergency requiring immediate removal from play and cooling.
Question 7: Spondylolysis in adolescent tennis players most often affects which region of the spine?
- Cervical vertebrae C3–C5
- Thoracic vertebrae T4–T6
- Lumbar vertebrae L4–L5 (Correct answer)
- Sacral segments S1–S2
Correct answer: Lumbar vertebrae L4–L5
Repetitive hyperextension during serves and overheads concentrates stress fracture risk at the L4–L5 pars interarticularis in adolescent athletes.
