摘要
Previous work has demonstrated that acute exercise prior to memory encoding may enhance long-term memory.Similarly,other work demonstrates that acute exercise during the memory consolidation period may also enhance long-term memory function.However,no study has evaluated whether long-term memory is enhanced when an acute bout of exercise occurs during both of these time periods,when compared to just prior to memory encoding.A within-subject randomized con-trolled intervention was employed.On separate laboratory visits,participants completed two main protocols,including(1)exercise before memory encoding and(2)exercise before and after memory encoding.Long-term memory was assessed,via a word-list task,from a 20-min delay period and a 24-h delay period.We observed a significant main effect for time,F(8,176)=529.5,P<0.001,ηp^(2)=0.96,but no significant main effect for condition,F(l,22)=0.08,P=0.77,ηp^(2)=0.004,or time by condition interaction,F(8,176)=0.19,P=0.99,ηp^(2)=0.009.In conclusion,there was no difference in long-term memory function when comparing acute exercise only prior to memory encoding vs.acute exercise both before and immediately after memory encoding.
