The Order Effect of Acute Concurrent Exercise on Executive Function: An Event-Related Potential Study

Not Applicable

Completed

• Conditions: Executive Function
• Interventions: Behavioral: aerobic-resistance exercise, AR; Behavioral: resistance-aerobic exercise, RA

• Registration Number: NCT05314699
• Lead Sponsor: National Taiwan Normal University

Brief Summary

Executive function is a high-level cognition which plays an important role in our life. Meta-analysis study has demonstrated that acute exercise could improve executive function. However, it is still unclear whether executive function can be enhanced by the concurrent exercise that combines aerobic and resistance exercise. Moreover, the sequence of concurrent exercise may result in different blood lactate concentration which may affect executive function. Therefore, the purposes of present study are: (1) Measuring the order effect of acute concurrent exercise on executive function. (2) Measuring whether order effect of acute concurrent exercise on executive function is mediated by blood lactate.

Detailed Description

Executive function is a high-level cognition which plays an important role in academic performance, career, and interpersonal relationship. Meta-analysis study has demonstrated that acute exercise could improve executive function, and also observed similar positive effect through both aerobic and resistance exercise. However, it is still unclear whether executive function can be enhanced by the concurrent exercise that combines aerobic and resistance exercise. Moreover, the sequence of concurrent exercise may result in different blood lactate concentration which may affect executive function. Therefore, the purposes of present study are: (1) Measuring the order effect of acute concurrent exercise on executive function. (2) Measuring whether order effect of acute concurrent exercise on executive function is mediated by blood lactate.

Arm && Interventions

Group	Intervention	Description
aerobic-resistance exercise group, AR	aerobic-resistance exercise, AR	Participants conduct 5-min warm up, 12-min aerobic exercise, 13-min resistance exercise, and 5-min cool down.
resistance-aerobic exercise group, RA	resistance-aerobic exercise, RA	Participants conduct 5-min warm up, 13-min resistance exercise, 12-min aerobic exercise, and 5-min cool down.

Primary Outcome Measures

Name	Time	Method
Stroop test	30 minutes	The Stroop task consists of neutral, congruent, and incongruent trials. In neutral trials, colored rectangles were presented and participants were instructed to respond to whether the squares were red, blue, or green. For congruent and incongruent trials, participants were presented with the names of the three Chinese color words of 紅 (red), 藍 (blue), or 綠 (green) printed in either the same (congruent) or different (incongruent) ink color and instructed to respond to the color of the ink while inhibiting the meaning of the word.
task switch test	30 minutes	The shifting aspect of executive function was assessed by means of a computer version of the task-switching test. In brief, each participant was presented with six blocks of 64 trials. For the first block, the participant was required to identify whether the stimulus (i.e., digits 1-9, without digit 5) within the solid-line square was greater/less than the digit 5. For the second block, the participant identified whether the stimulus within the dotted-line square was even/odd. The blocks 3-6 consisted of an equal number of stimuli from the first and second blocks forming an alternating-runs paradigm.
