According to the results of these tests, training can be individualized, supplemented, or adjusted to optimize performance. 4 The Swedish Tennis Federation has a test battery including flexibility and fitness testing for competitive tennis players aged 12–20 years. However, the average time to perform the test is approximately 15–17 seconds for junior males and females, which is longer than an average point in tennis. 11 This test is easy to administer and the movement patterns simulate a lot to the actual movements observed during tennis play. 10Ī physical fitness test that is frequently used by the US Tennis Association to evaluate agility in competitive tennis players is “the spider run test”. Such tests are often inexpensive and easy to perform. ![]() 10 Therefore, there is a need for more reliable and valid sports-related functional tests, aiming to test different aspects of physical fitness and athletic performance. How do the results of these tests represent for physical performance is still not clear. Furthermore, these tests are aimed at measuring only one specific parameter, eg, muscle strength. 10 Compared to functional tests, laboratory measurements are less accessible and also often expensive. Moreover, these parameters are most often tested in a laboratory setting. 9 To the best of our knowledge, there are a restricted number of reliable functional tests for determining physical fitness, especially concerning speed and agility, that exist in the literature. 8 The test also needs to be specific to the demands of the sport that the subject is practicing. The usefulness of a test depends on its reliability or the extent to which a test is consistent and free from error. 7 To identify areas of reduced fitness, it is important to conduct a regular physical fitness testing. ![]() 6 Furthermore, it is hypothesized that a nonfunctional movement pattern can predispose for injuries. 5 Also, acute injuries are common problems in pivoting sports that include cut movements, sudden accelerations, stops and turns, since these can place substantial demands on ankles, knees, and hips. Repetitive multidirectional movement patterns can lead to lower extremity injury. 3 Due to these findings, it is important to train and test tennis players in the specific movement patterns and running distances that are encountered during match play, typically high-intensity work for approximately 4–10 seconds. 2 A study in junior tennis players that compared short straight sprints with agility, including multidirectional running, showed that these are specific qualities that are most of the time unrelated. The movement pattern is characterized by quick starts and stops, accelerations, decelerations, and multidirectional movements. 1 This complexity requires tennis athletes to have fast reaction times and the ability to perform explosive agility movements. Further, it is also a physically demanding sport. Tennis is a complex sport since it involves technical and tactical skills.
