The aim of the current study was to develop a unique test for assessing lower limb explosive power in basketball players in the field and to assess its reliability and validity. Indeed, the game of basketball requires players to use lower limb explosive power for performing horizontal and vertical movements, as well as complex jumps that require a combination of the two [1; 5]. Players also need to have strong coordination capabilities between their upper and lower limbs for performing actions, such as penetration to the basket through layups, while continuously maintaining control of the ball [1; 8]. The main findings of the study indicate a high correlation between the test/retesting results for both legs. For the horizontal tests, the highest correlation was seen for the 10 m sprint test. The highest correlation was seen for the BP test (r > 0.9), where both horizontal and vertical skills were combined. In 2017, [PERSON] et al. [32] examined the reliability and validity of two standardized tests for vertical jumps (CM) and the Abalakov jump) and two specific jump tests that combine both horizontal and vertical abilities (run-up and 2-LEGS or 1-LEG take-off jump). The researchers examined these tests as predictors of sprint and strength performance among soccer and basketball players. All four tests presented high intraclass correlation coefficients, regardless of the players' age or sport. The 1-LEG test presented slightly greater variability than the other three tests, as well as the least validity. The researchers explained these findings as the result of the more complex motor structure of this jump. Indeed, assessing the 1-LEG test among both soccer and basketball players may have created a limitation, as these two ball games require different physical abilities [16; 33]. [PERSON] et al. 's [32] findings led us to create a more unique 1-LEG test specifically for basketball players, assessing a basic movement that is learned and acquired when one first begins to play basketball, yet this test is constantly repeated during practice and games at all levels and ages while holding a ball. As such, the use of the ball during tests should not perceived as a limitation and may even be advantageous when assessing jumping, specifically among basketball players [1; 11]. The skills exhibited in the novel test are relatively complex, requiring explosive power on two planes (horizontal and vertical) while holding a ball. However, for professional basketball players, these are basic, frequently used skills in both warmups, practice, and games [10]. For this reason, we chose to only assess highly experienced basketball players from professional clubs--to ensure that they possess very good control of the examined movement, and this was performed as a means of decreasing the limitation of a learning curve (i.e., learning a new skill specifically for the test) between the test and the retest. Moreover, unlike previous studies, we assessed a combination of a horizontal jump of up to 1.5 m forward--as the jump in the test was performed after a horizontal run with the ball and as a natural continuation of this action [11; 32]. The main findings of the study indicate a high correlation between the test/retesting results for both legs, with mean scores remaining very similar. The magnitude of correlation
