optimal levels of agility as many of the tasks they perform involve speed, twists, and turns ( 23 ). This underscores the need for accurate assessment and training of agility performance in childhood. Agility has historically been defined as an individual’s ability to run and change direction quickly ( 15

and badminton, table tennis players are reported to be more agile at side stepping. 3 In addition, table tennis stroke skills are also crucial, which can be quantified by ball speed. Therefore, power, agility, and ball speed play essential roles in a table tennis player’s ability to win competitions

Agility running is a key component of soccer performance and includes accelerations, decelerations, changes of direction, and initiations of whole-body movements. 1 The frequency of such soccer-specific movements (>700 cuts and turns within a match by a player in the English football association

Hence, this study evaluated the content validity of the new classification system for CP football through a COD test (ie, modified agility test [MAT]) and explored the validity and reliability of a new dribbling test to correctly classify international CP football players.

The purpose of the current study was to assess the reliability of a new protocol that examines different components of agility using commercially available timing gates.
Seventeen physically active males completed four trials of a new protocol, which consisted of a number of 10-m sprints. Sprints were completed in a straight line or with a change of direction after 5 m. The change of direction was either planned or reactive, with participants reacting to a visual light stimulus.
There was no systematic bias in any of the measures, although random variation was reduced in the straight acceleration and planned agility when considering only the fnal pair of trials, with mean coefficients of variation (CV) of 1.6% (95%CI, 1.2% to 2.4%) and 1.1% (0.8% to 1.7%), respectively. Reliability of reactive agility remained consistent throughout with mean CVs of approximately 3%. Analyses revealed a high degree of common variance between acceleration times and both planned (r 2 = .93) and reactive (r 2 = .83) agility, as well as between the two agility protocols (r 2 = .87).
Both planned and reactive agility could be measured reliably. Protocol design and use of a light stimulus in the reactive test emphasize physical abilities comparable with other test measures. Therefore, inclusion of a reactive light stimulus does not appear to require any additional perceptual qualities.

Agility tests demand quick deceleration, direction change, and reacceleration during the movements. 16 These 3
