Agility is an important ability for tennis players. To be successful in the rallies, players must perform rapid, multidirectional movements in response to the ball and/or the opponent. For a test to be representative in monitoring agility performance, it should capture a combination of the physical and cognitive agility performance. While literature reports no reliable and valid sport-specific agility test for tennis, the aim of this article was to design and evaluate the measurement properties of the Tennis-specific Agility Test (TAT). To evaluate the TAT, feasibility, test-retest reliability and concurrent validity were assessed. For reproducibility, a two-way mixed ANOVA was performed. Concurrent validity was assessed using Pearson correlations. A total of 69 tennis players participated in this study of which 16 internationals (22 ± 3.7 years), 43 nationals (14 ± 1.4 years), and 10 regionals (15 ± 0.8 years). Test-retest reliability was found to be moderate (ICC=.74; p<.01) with a percentual minimal detectable change (%MDC) of 6.2%. Comparing the outcomes on the TAT with a recognised agility test, the Spider Drill, which measures only the physical component of agility, resulted in a moderate correlation of .70 (p<0.01). The association between the tennis performance level and the completion time on the TAT showed a significant correlation for both boys (r=.67; p<.01) and girls (r=.72; p<.01). The feasibility was high with short time for preparation (five to ten minutes) and time per participant (<5 minutes). In conclusion, the TAT shows promising results for assessing sport-specific agility performance in tennis making it likely to be used in the practical setting.
