Differential shooting training in youth basketball players: an analysis of performance effects

Introduction Differential Learning introduces increased variability during practice to enhance motor skill acquisition. Methods This study investigated the effects of Differential Training (DT) (Differential Training Group (DTG): n = 19, age = 13.1 ± 0.19 years, height = 170.1 ± 9.5 cm, body mass = 56.9 ± 9.7 kg, training experience = 6.4 ± 1.3 years, maturity offset = 0.7 ± 0.8 years) on shooting accuracy and 1 × 1 small-sided game performance, compared to Traditional Training (TT) [Traditional Training Group (TTG): n = 18, age = 13.8 ± 1.1 years, height = 171.3 ± 8.6 cm, body mass = 59.4 ± 15.4 kg, training experience = 6.5 ± 1.5 years, maturity offset = 0.5 ± 1.1 years], in youth basketball players for an 8-week intervention (16 sessions). Outcomes included 2-point (2-pts) and 3-point (3-pts) shooting accuracy test (BJSAT), 1 × 1 scoring performance, stationary shooting accuracy test (SSAT), and rate of perceived exertion (RPE). Results Linear mixed-model analyses revealed that DT improved two-point BJSAT relative to TT at post-test ( β = −2.48; p = 0.042) and gains were maintained at retention ( p = 0.001). Three-point BJSAT improved over time in both groups ( p = 0.004) with no between-group difference at retention. 1 × 1 SSG scoring increased over time ( p < 0.001) with no between-group effect at retention. DT outperformed TT in the 30-shot task (Δ = 3.11, 95% CI [1.59, 4.63]; p < 0.001) and elicited lower RPE (Δ = −0.96, 95% CI [−1.47, −0.46]; p < 0.001). Discussion These results indicate a superior efficacy of DT for improving shooting performance and managing perceived effort. The differential adaptation rates between mid- and long-range shooting highlight the value of movement variability in skill learning. However, limited transfer to SSG outcomes suggests further research is needed to optimize DT protocols for complex game contexts.
