简要总结

An increasing amount of studies show the beneficial effect of regular exercise on cognitive and brain functions and especially in the memory domain. Yet little is known of what happens within an acute bout of exercise and whether it would also yield cognitive effects. The literature clearly shows that molecules such as brain derived neurotrophic factor (BDNF) and endocannabinoids (mainly anandamide, AEA) are heavily involved in neural plasticity mechanisms and increase when we exercise hinting at possible mechanisms underlying memory improvement after exercise.

This protocol assesses the effects of acute exercise on associative and motor sequence memory, their underlying neural activations (measured using fMRI) and blood biomarkers (BDNF and AEA). A related aim is to assess the effect of exercise intensity, therefore three exercising conditions (rest, moderate intensity and high intensity) were included. Finally, a 3-month delayed retest visit is also realized to assess effects of acute exercise on long-term memory consolidation.

结局指标

主要结局

BDNF levels

时间窗: up to 1 hour

we measure BDNF levels before and after physical exercise and rest, measured in ng/mL of serum.

endocannabinoid levels

时间窗: up to 1 hour

we measure endocannabinoid levels before and after physical exercise and rest, measured in ng/mL of plasma.

cognitive measures - performance

时间窗: Till the end of the study for each participant, i.e.3 months (long time retest)

we measure performance during cognitive tasks. Performance is measured as percentage of correct trials, with higher percentages corresponding to better performance - measured in percentages.

cognitive measures - reaction times

时间窗: Till the end of the study for each participant, i.e.3 months (long time retest)

we measure reaction times during cognitive tasks. For reaction times, lower measures correspond to faster response times and therefore to better outcome - measured in milliseconds.

brain activations

时间窗: up to 1 hour

we measure brain activations using fMRI during cognitive tasks
