A Review of Reactive and Non-reactive Agility Tests Concerning Neurologic Aspects

Agility is an essential component of sport performance, especially in ball sports. It is also a significant indicator of sport skills under competitive conditions. Agility is one of the most critical factors in the sport performance of soccer players. Agility and coordination of the nervous-muscular system to produce maximum force, as an important factor of function and physical fitness, which is considered along with perception and decision making in unpredictable situations. Assessment tests for assessing agility are divided into two general areas called non-reactive agility as well as reactive agility test. Although non-reactive agility tests are superior to reactive agility tests in terms of reliability, reactive agility tests are more similar to the movement and skill pattern in soccer and can distinguish players from each other well. In reactive agility tests, the movement path of the experimenter is not predictable and not all changes in path are predetermined and exactly the movement pattern in the soccer game where the movement path of the player is not predictable and the movement path of the ball as well as the prevailing conditions in the game that determine and change of direction player at any moment. The results showed that non-reactive agility had a higher relative validity and reliability than reactive agility. This small difference was acknowledged by researchers related to the reactivity and complexity of reactive agility tests. finally a review of the above studies and findings confirms that the use of reactive agility tests is necessary to evaluate athletes
