title: Determinants of performance in a new test of planned agility for young elite basketball players.
abstract: OBJECTIVE
  To investigate the reliability and determinants of performance in a new test of planned agility in elite junior basketball players.
  
  
  METHODS
  Seventeen female (15.1±0.4 y, 176.9±11.2 cm, 65.7±10.9 kg) and 42 male (14.9±0.4 y, 193.7±8.1 cm, 79.0±12.0 kg) elite junior basketball players performed 5 fitness tests presented in a random order, including a 20-m sprint, a planned-agility test, a triple bilateral horizontal countermovement jump, and 2 triple unilateral horizontal countermovement jumps (with each leg separately). The novelty of the planned-agility test is that it included both offensive and defensive movements. The determinants of planned agility were assessed by a stepwise-regression analysis, and the reliability of the new test was evaluated by the intraclass correlation coefficient and the typical error of measurement.
  
  
  RESULTS
  The main results show good reliability of the new test of planned agility. In addition, the determinants of planned-agility performance were different between genders, with sprint performance explaining 74.8% of the variance for girls, while unilateral jump performance and body mass were the most important for boys, accounting for 24.0% and 8.9% of the variance, respectively, in planned agility.
  
  
  CONCLUSIONS
  These results highlight a gender effect on the determinants of planned-agility performance in young elite basketball players and suggest that straight-line sprint and unilateral horizontal tests must be implemented to test elite junior players.
