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? Compared to no-exercise controls, exercising four hours after encoding — but not immediately — enhanced retention of picture-location associations and hippocampal pattern similarity at 48-hour cued recall. → Basso Julia C. 2017

q2 · i? · review · r3

fMRI study in which subjects encoded picture-location associations then rested or exercised (35 minutes of interval cycling at 80% maximum heart rate) immediately or four hours later, returning 48 hours after for cued recall. Quotes the fragment "four hours, but not immediately, after encoding enhanced retention".

"Compared to the no exercise controls, performing exercise four hours, but not immediately, after encoding enhanced retention of the picture-location associations"

Discussion¶

Learner Variables¶

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

The timing of acute exercise relative to learning modulates memory consolidation — a broader claim this one bears on
Spending more time sedentary 1 to 2 hours after encoding is associated with better long-term memory retention, implying physical activity in that window is detrimental — reports the opposite
Physical activity in the hour before memory retrieval is associated with superior memory retention, while sedentary time in that window is negatively associated — related
Physical well-being — exercise, sleep, and nutrition — impacts learning — a broader claim this one bears on
A combined model of demographics, aerobic fitness, and the two critical activity windows accounts for over 30% of variance in long-term memory retention — related
