Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? A significant Exercise Group × Block interaction occurred for force error only, with HIIT showing greater accuracy improvement; trial time, reaction time and movement time showed no interactions. → Brooks 2026
Evidence¶
Brooks 2026¶
Brooks, E., Hawi, Z., Hosler, J. et al. (2026). High-intensity cardiovascular exercise facilitates online motor skill learning, with no effect of BDNF genotype. npj Science of Learning. https://doi.org/10.1038/s41539-026-00432-8
q2 · i? · causal · r1
Linear mixed models of four secondary skill components (trial time, force error, reaction time, movement time) across all 51 participants; only force error showed a Group × Block interaction, consistent with HIIT improving accuracy rather than speed.
"However, an interaction of Exercise Group x Block was observed for force error (F5, 254 = 2.52, p = .03), indicating that over the session participants in the HIIT group demonstrated a greater improvement in accuracy compared to the control group"
Discussion¶
Related Claims¶
- 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 — a broader claim this one bears on
- 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
- Trial time during acquisition was unaffected by exercise group but slowed over blocks for older participants — related
- Force error increased at retention for the rest group but not the exercise group — related
- Exercise eliminated the offline skill decline seen after rest: the rest group lost skill over the 6-hour delay while the exercise group did not — related
- HIIT participants achieved greater total SVIPT learning than active controls over the session (d = 0.58) — related
