Evaluation of stroke performance in tennis

Area of Science:

• Sports Science
• Biomechanics
• Performance Analysis

Background:

• Elite tennis performance relies on precise stroke execution under match-like conditions.
• Existing performance tests may not fully replicate the dynamic demands of competitive play.
• A need exists for a validated tool to objectively assess tennis stroke quality in research settings.

Purpose of the Study:

• To evaluate the Leuven Tennis Performance Test (LTPT) for its research utility in assessing tennis stroke performance.
• To determine the validity and sensitivity of the LTPT in distinguishing between player skill levels and detecting fatigue.

Main Methods:

• The LTPT involves elite players executing serves and returns to programmed target zones under varying tactical situations.
• Stroke quality is quantified using error rate, ball velocity, and precision of placement.
• Derived indices include Velocity/Precision (VP) and Velocity/Precision/Error (VPE).

Main Results:

• Higher-ranked players demonstrated significantly fewer errors and superior stroke velocity, precision, VP, and VPE scores compared to lower-ranked players.
• Induced fatigue led to increased error rates and decreased stroke velocity and the VP/VPE indices.
• These findings confirm the LTPT's ability to differentiate skill levels and reflect fatigue.

Conclusions:

• The Leuven Tennis Performance Test (LTPT) is an accurate, reliable, and valid instrument for evaluating stroke quality in high-level tennis players.
• The LTPT is suitable for research purposes, offering objective insights into performance factors.
• The test effectively captures nuances in stroke execution influenced by player ranking and fatigue.
