Abstract

The objective of this study was to investigate the construct validity and reliability of a new reactive multidirectional repeated sprinting test (RRSA5COD) in basketball players. Forty male basketball players were divided into two groups: Professional (PRO; n = 20) and Semi-professional (SEMI; n = 20). Participants completed the yo-yo intermittent recovery test level 1 (Yo-YoIR1), the squat jump (SJ), the counter movement jump (CMJ), the single leg drop jump (DJ), the 20-m sprint test, the planed multidirectional repeated sprinting test (PRSA5COD), and the RRSA5COD test. Reaction time (RT) and movement time (MT), total time (TT), best time (BT), and fatigue index (FI) were assessed. Heart rate (HR) was continuously recorded, while rating of perceived exertion (RPE) and blood lactate concentration (LA) were measured post-tests. The reliability of the RRSA5COD test was also assessed between two attempts with one week between them. The RRSA5COD results demonstrated to be reliable with most of the variables showing ICC > 0.80. BA Bonferroni post hoc revealed a significant better TT in favor of RRSA5COD (p < 0.001; ES = 0.15; small), and in favor of PRO (p < 0.001; ES = 0.006; small). The result showed a significant better performance in favor of PRO in all physical fitness tests. In conclusion, it was found that the RRSA5COD discriminates between professional and semi-professional male basketball players, and the results were demonstrated to be reliable.
