Subclaims¶

q3 i? There were no differences between HIIT and LOW groups on total early learning, micro-online or micro-offline learning, with Bayesian evidence favouring the null (BF10 values 0.47, 0.36, 0.37). → Emily Brooks 2024

Emily Brooks, Sarah Wallis, Joshua Hendrikse & James Coxon. (2024). Micro-consolidation occurs when learning an implicit motor sequence, but is not influenced by HIIT exercise. npj Science of Learning. https://doi.org/10.1038/s41539-024-00238-6

q3 · i? · causal · r2

Independent-samples t-tests and Bayesian t-tests compared HIIT (n = 19) and LOW (n = 19 minus aware participants) groups after a 20-min exercise bout. The article reports "no differences between the HIIT and LOW groups across primary outcome variables"; BF10 = 0.47 for total learning, 0.36 micro-online, 0.37 micro-offline. No effect sizes are printed, so impact is null.

"There were also no differences between the HIIT and LOW groups across primary outcome variables [total early learning (HIIT:M = 0.63,SD = 0.15, LOW:M = 0.56,SD = 0.27), t (32) = -0.96, p = 0.34, 95% CI [ -0.23, 0.08], BF10 =0 . 4 7"

Discussion¶

Learner Variables¶

• Long-Term Memory — outcome: instruction changes it
• Physical Well-Being — predictor: learners who differ on it differ in outcomes

Related Claims¶

• Early learning of an implicit motor sequence is accounted for by micro-offline gains during brief rest periods rather than by gains during active practice — related
• The timing of acute exercise relative to learning modulates memory consolidation — related
• Performance improvements during early motor skill learning occur predominantly during short rest periods (micro-offline gains), replicated in a large crowdsourced sample and in a laboratory study — related
• Random termination of practice periods does not reduce micro-offline gains, ruling out preemptive motor slowing — related
• Halving practice-period duration from 10 s to 5 s leaves micro-offline gains unchanged, arguing against recovery from motor fatigue — related
• Micro-offline gains are inconsistent with a dominant contribution of latent motor slowing, supporting consolidation as their driver — related
