Subclaims¶

q2 i2 Total learning, defined as the change in skill from start of block 1 to end of block 6, was greater in the HIIT group than the active control group, d = 0.58. → 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 · i2 · causal · r2

Independent-samples t-test on a single total learning metric per participant in the same 51-participant mixed factorial experiment, confirming "greater total learning" for HIIT over active control with "a medium effect size, d = 0.58".

"We further calculated a single tota l learning metric for each participant (see methods) and confirmed greater total learning (mean difference of 1.00, 95% CI [0.033, 1.96]) for the HIIT group (M = 3.07, SD = 1.86) compared to the active control group (M = 2.08, SD = 1.52), t(49) = -2.08, p = .043, with a medium effect size, d = 0.58"

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 — possibly the same claim (merge candidate)
• HIIT did not selectively influence online or offline learning subcomponents relative to active control — related
• The HIIT and active control exercise conditions were physiologically distinct, confirming the intended exercise manipulation — related
• The HIIT benefit on skill learning is driven primarily by improved accuracy, shown by a Group × Block interaction for force error — related
