Mixed
Fatigue significantly reduces hitting accuracy (up to 81%) and alters biomechanics, making rest periods critical for technical drills.
When practicing shots, ensure you are not fatigued. If you are tired, your accuracy drops by up to 81% and your mechanics break down, increasing injury risk. Use longer rest periods during technical drills to maintain high-quality movement patterns.
GoodSupportsHIGH confidence
Hitting accuracy is reduced by as much as 81% when a tennis player is nearing volitional fatigue... When working on technical issues, it is essential to give appropriate rest. It is imperative to use work/rest ratios that provide the coach and athlete with the right environment for optimum outcome.
Why this rating
Supported by multiple studies cited (Davey et al., Ferrauti et al.) showing clear correlations between fatigue and performance decrements.

- Tennis training must be specific to match the sport's intermittent nature (points of 3-15 seconds with 1:2 to 1:5 work-to-rest ratios) rather than relying on general endurance or continuous aerobic training.Good
- Tennis players require specific shoulder flexibility training to prevent injury, as playing alone does not improve external rotation and may lead to imbalances.Good
