Subclaims¶

q3 i? No significant main effect of Group on trial time; a Block × Age interaction showed older participants decreased speed over time while younger-old did not, and this did not vary across rest and exercise. → Eleanor M. Taylor 2024

q3 · i? · causal · r2

Acquisition analysis of the speed measure in the same study. The article reports "no signi ficant main effect of Group (F(1, 19.00) = 0.72, p = 0.40)", a Block × Age interaction (F(1, 19.00) = 7.62, p = 0.01), and no Group × Block × Age effect (p = 0.16). Null result; equivalence not tested.

"Analysis of trial time revealed no signi ficant main effect of Group (F(1, 19.00) = 0.72, p = 0.40), though there was a main effect of Block"

Discussion¶

Related Claims¶

• High-intensity exercise prior to practice reduced skill acquisition in older adults, with the detriment specific to the oldest participants — related
• The acquisition detriment after exercise was driven by the accuracy subcomponent: older participants reduced force error after rest but not after exercise — related
• The HIIT benefit on skill learning is driven primarily by improved accuracy, shown by a Group × Block interaction for force error — related
• A preceding HIIT bout enhances skill acquisition on a novel visuomotor task relative to an active control, with group differences emerging from Block 4 of practice — related
