q3 i? After controlling for age, sex, and aerobic fitness, neither percent time sedentary nor percent time in moderate-to-vigorous physical activity over the whole day related to the proportion of paired-associate items maintained across 12 hours. → Pontifex 2016

q3 · i? · associational · r2

Hierarchical regression on 92 undergraduates' paired-associate retention across a 12-hour interval, controlling for Age, Sex, and Aerobic Fitness. Percent time sedentary showed "No relationship to long-term memory" (β = −0.130, p = 0.19), as did moderate-to-vigorous activity (β = 0.119, p = 0.23). No effect sizes printed.

"No relationship to long-term memory was observed for either the percentage of time spent sedentary (β = − 0.130, t (87) = 1.3, p = 0.19), or the percentage of time spent in moderate-to-vigorous physical activity (β = 0.119, t (87) = 1.2, p = 0.23), after controlling for Age, Sex, and Aerobic Fitness"
