Subclaims¶

q2 i? Comparisons of the final HIIT interval with the active control session showed significant differences on all exercise parameters with large effect sizes (e.g., %HRR d = 8.56). → 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 · r2

Manipulation check in the 51-participant experiment comparing HIIT interval 4H (e.g., 85.97% HRR) with the active control session (21.70% HRR); all parameters differed significantly with large effect sizes (p < .001, d = 2.93–8.56 per Table 2).

"Independent samples t-tests compared the final interval of the HIIT group (4H) with the AC for each exercise parameter, which showed significant differences between the exercise conditions, all large effect sizes, confirming our intended manipulation of exercise condition."
