q3 i? Individuals with greater aerobic fitness (VO2max percentile) maintained a greater proportion of learned paired-associate items across the 12-hour interval, even after controlling for Age and Sex. → Pontifex 2016

Pontifex 2016¶

Pontifex, M. B., Gwizdala, K. L., Parks, A. C., Pfeiffer, K. A. & Fenn, K. M. (2016). The Association between Physical Activity During the Day and Long-Term Memory Stability. Scientific Reports 6, 38148. https://doi.org/10.1038/srep38148

q3 · i? · associational · r2

Hierarchical regression in the same 92-participant paired-associate study, with VO2max percentile entered beyond descriptive factors. Greater fitness predicted "a greater proportion of items maintained" (β = 0.225, p = 0.032). Only a standardized β is printed; no effect size.

"Hierarchical regression analysis indicated that individuals with greater-fitness exhibited more stable long-term memory as indexed by a greater proportion of items maintained between session 1 and session 2 (β = 0.225, t (88) = 2.2, p = 0.032), even after controlling for Age and Sex"

Related Claims¶

• Total percentage of time spent sedentary or in moderate-to-vigorous physical activity during the day is unrelated to long-term memory retention in young adults — related
• 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 — related
• 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
• Physical activity in the hour before memory retrieval is associated with superior memory retention, while sedentary time in that window is negatively associated — related
• Memory recall declines over the 12-hour retention interval between encoding and retrieval — related
• The timing of acute exercise relative to learning modulates memory consolidation — related
