The purpose of this study was to determine the reliability and validity of the Aspire Table Tennis Agility Test (ATTAT). The ATTAT was developed from performance analysis data to measure preplanned agility in highly-trained young table tennis athletes (n= 10, 15.0 ± 1.5 y). The ATTAT consisted of a linear step, linear jump, pivot and two lateral movements in sequence at the table and 3 stationary balls were hit by the racket in hand. The mean time take to complete the ATTAT was 3.94 ± 0.75 s. Reliability was measured using a typical error (TE) score from 10 consecutive pairs of trials 3 days apart. The TE score for the test was 3.98% demonstrating that the ATTAT is reliable at the 90% confidence limit. Validity was investigated using a Spearman`s rank correlation analysis comparing the ranking of 10 ATTAT scores against an expert coach`s perceived ranking of agility (technique of changing direction) in table tennis and a ranking of leg muscle qualities (physical capability) derived from 3 jump tests. Validity was considered high with correlation coefficients of 0.88 and 0.79 for the coach`s ranking and leg muscle qualities ranking respectively.
