ITF Injury Prevention 2 — Questions and Answers
Question 1: Which muscle group is most commonly strained in tennis players due to explosive serve mechanics?
- Quadriceps
- Rotator cuff (Correct answer)
- Tibialis anterior
- Biceps brachii
Correct answer: Rotator cuff
The rotator cuff undergoes extreme eccentric loading during the deceleration phase of the serve, making it the most commonly strained muscle group.
Question 2: What is the recommended minimum dynamic warm-up duration before a competitive tennis match?
- 5 minutes
- 10 minutes
- 20 minutes (Correct answer)
- 30 minutes
Correct answer: 20 minutes
A 20-minute dynamic warm-up is recommended to adequately raise core temperature, increase joint mobility, and prepare neuromuscular systems for match play.
Question 3: Which type of stretching is most appropriate immediately before tennis play to reduce injury risk?
- Static stretching
- Ballistic stretching
- Dynamic stretching (Correct answer)
- PNF stretching
Correct answer: Dynamic stretching
Dynamic stretching mimics sport-specific movements and is preferred pre-activity because it maintains muscle activation and does not reduce force production.
Question 4: Lateral ankle sprains in tennis most commonly result from which movement pattern?
- Forward sprinting
- Jumping and landing on an inverted foot (Correct answer)
- Backpedaling
- Serving motion follow-through
Correct answer: Jumping and landing on an inverted foot
Rapid direction changes and jumping often cause an inverted foot landing, overstretching the lateral ankle ligaments and causing a sprain.
Question 5: Which training principle helps reduce overuse injuries by systematically varying training load?
- Specificity
- Periodization (Correct answer)
- Overload
- Reversibility
Correct answer: Periodization
Periodization structures training cycles with planned variation in volume and intensity, preventing chronic overload and reducing overuse injury risk.
Question 6: What ITF guideline governs the maximum number of sets junior players under 12 should play per day?
- No more than 1 set
- No more than 2 sets
- No more than 3 sets (Correct answer)
- No more than 4 sets
Correct answer: No more than 3 sets
ITF guidelines recommend a maximum of 3 sets per day for players under 12 to protect developing musculoskeletal systems from overuse.
Question 7: Core stability training primarily reduces which type of tennis injury?
- Wrist fractures
- Lower back pain and lumbar stress injuries (Correct answer)
- Plantar fasciitis
- Elbow tendinopathy
Correct answer: Lower back pain and lumbar stress injuries
A strong, stable core reduces shear forces on the lumbar spine during rotational strokes, lowering the risk of lower back pain and stress injuries.
