Abstract

The aims of this current study were to assess the longitudinal development of repeated sprint ability (RSA) in adolescence and to determine its possible underlying mechanisms. Talented youth basketball players aged 12-19 year (n = 43) were measured three times in the 2008- 2009 season and two times in the 2009-2010 season, resulting in a total of 122 measurements. Three field tests, the Shuttle Sprint Test (SST) for RSA, the Vertical Jump (VJ) for anaerobic power and the Interval Shuttle Run Test (ISRT) for interval endurance capacity were assessed. Height, weight, fat percentage and lean body mass (LBM) were recorded. The longitudinal data were analyzed with multilevel modeling. Moderate correlations were found between SST and the VJ (r = -0.58), the SST and the ISRT (r = -0.45) and the VJ and the ISRT (r = 0.39) illustrating that they are related but measure distinct qualities. The multilevel model revealed that RSA improved with age during adolescence, especially during 14-17 years (p < .05). Besides age, VJ, ISRT and the interaction age x VJ significantly contributed to performance on the RSA (p < 0.05). In addition, position and anthropometric variables did not significantly contribute to performance on RSA (p > 0.05) although there was a tendency for position (p = 0.052). RSA measured with the SST can be predicted by the equation 45.199 - 0.946 x age- 20.721 x VJ- 0.013 x ISRT + 1.061 x age x VJ. This research shows that RSA increases especially from 14-17 years during adolescence. The tendency for the variable position could be of value for trainers and coaches for individualizing training programs. In addition, RSA could be trained by short burst high intensity activities like jumping and intermittent aerobic exercises in talented basketball players.
