## 5 Conclusions and Practical Applications  
The study focused on familiarization with and the validity of four tests of non-reactive agility, which in previously published studies had, among other things, been also used as an instrument to evaluate the level of motor performance of female basketball players, i.e., the various subcomponents of one complex motor ability such as agility. The results of this study indicate the need for and importance of motor learning when performing the applied tests of preplanned agility. This would make it possible to determine differences adequately and objectively in the existing characteristics, i.e., by means of the current level of development of this multidimensional motor skill among professional basketball players. The study determined that the results of the aforementioned tests are significantly affected by the number of series performed during familiarization, and that when preparing for measurement, it is necessary to perform two series of UN and FR tests, i.e., four series of repetitions regarding the practical application of the SC and LA tests among senior female basketball players. In addition, based on the results obtained, it could be concluded that the validity of the applied tests was confirmed, and that the LA, UN, FR, and SC tests can be used as a suitable measure to determine the differences in the quality and level of the aforementioned subcomponents of non-reactive agility among female basketball players. The results indicate the importance of familiarization, confirm the validity of the applied tests, and encourage coaches and researchers interested in women's basketball to use these tests more frequently as a diagnostic measure, to evaluate and determine objective differences in the current performance of complex motor skills such as agility. By determining the objective level of development of the subcomponents of agility of female basketball players and noting their shortcomings in motor status, it is possible to, in an adequate manner, affect the quality of planned and programmed training activities with the aim of forming a suitable model of an athlete needed to achieve the best possible results. The application of these tests in the training process through frequent testing and implementation of activities focused on the development of agility in women's basketball, as an ability which is highlighted as an important element, can contribute to the achievement of the desired competitive form and lead to the realization of determined competitive goals which the female basketball players and their coaches have set for themselves. In addition, the authors emphasize the high applicability of tests of non-reactive agility by using the FitLight TrainerTM system, since it is a wireless and easily transportable system which allows the transformation and use of these tests for the evaluation of the reactive agility and visual perceptive characteristics of athletes.
