q3 i? The five movement features significantly predicted javelin throwing distance, explaining 26% of the variance. → Christian Leukel 2025

q3 · i? · causal · r1

Multiple linear regression across all tested subjects (mirroring the secondary-school analysis) showed the feature model significantly predicted distance; the bracing step contributed most, and arm positioning, impulse step, and elbow positioning did not significantly contribute.

"the model explained 26% of the variance and significantly predicted javelin throwing distance (F (5,94) = 6.7, p <.001). Variation of distance was significantly explained by the orientation of the javelin (β = 0.26, t = 2.67, p <.01) and the bracing step (β = 0.42, t = 4.04, p <.001)."

Discussion¶

Related Claims¶

• Declarative knowledge of movement features was not significantly related to actual improvements in physical execution of those features
• Adding a practice phase after instruction (PS-I + P) did not improve javelin throwing performance over PS-I alone — related
• Primary school children improved execution of movement features but showed no improvement in javelin throwing distance across all conditions — related
• Working memory capacity did not moderate learning gains in PS-I and I-PS, but digit recall correlated with declarative knowledge of the features — related
