Overview
Brief Summary
This study explores the acute exercise effect on neurocognitive function and also its potential moderators in an exercise setting and Apolipoprotein E (APOE) genetic risk.
Detailed Description
Acute exercise has emerged as a modifier to multiple aspects of cognitive function; however, its effect on populations with different risks of Alzheimer's disease (AD) and the role of exercise variance and APOE genotype within the effect reminds underestimated. The current study aimed to examine the acute exercise effect on neurocognitive function from behavioral and neuroelectric perspectives among cognitively normal late-middle-aged adults. Additionally, we determined whether variations in exercise intensity and duration and the presence of the APOE ɛ4 allele modulated the effect.

Outcomes
Primary Outcomes
Stroop task: Accuracy
Time Frame: Participants were required to complete the Stroop task approximately 30 min following the cessation of each acute exercise treatment or the 30-min reading.
A computerized Stroop task was used to assess participants' inhibitory control and basic information processing. The accuracy was calculated for the second behavioral index.
Event-related potential: P3 amplitude
Time Frame: Participants were required to complete the Stroop task while EEG activity was continuously recorded approximately 30 min following the cessation of each acute exercise treatment or the 30-min reading.
The event-related potential from parietal electrodes (i.e., P3, Pz, and P4) were initially outputted for the mean P3 amplitude; the averaged mean P3 amplitudes from parietal electrodes was then calculated as the neuroelectrical indices.
Stroop task: Response time
Time Frame: Participants were required to complete the Stroop task approximately 30 min following the cessation of each acute exercise treatment or the 30-min reading.
A computerized Stroop task was used to assess participants' inhibitory control and basic information processing. The response time of the correct responses was calculated for the first behavioral index.
