Objectives

Narrative objectives1

The purpose of this study is to determine whether the effects of acute aerobic exercise on cognitive performance vary depending on cognitive task difficulty. By systematically manipulating task difficulty, we aim to identify the level of task difficulty at which the effects of acute aerobic exercise on cognitive performance are maximized.

Assessment

Primary outcomes

D-prime (sensitivity index) during the n-back task. D-prime will be assessed before and 10 minutes after the intervention. We will examine whether the difference in pre-to-post changes in d-prime between the exercise and seated rest conditions varies with task difficulty.

Key secondary outcomes

1. Reaction time for correct target responses (Hit RT) during the n-back task. Hit RT will be assessed before and 10 minutes after the intervention. We will examine whether the difference in pre-to-post changes in Hit RT between the exercise and seated rest conditions varies with task difficulty.
2. Pupil diameter during the n-back task will be assessed before and 10 minutes after the intervention as an index of cognitive effort. We will examine changes in pupil diameter as a function of task difficulty and investigate the relationship between pupil diameter and the magnitude of the effect of acute aerobic exercise on cognitive performance.

Interventions/Control_1

Participants will complete the exercise condition first, followed by the seated rest condition after an interval. The interval between conditions will generally be 3-14 days, although the second session may be postponed due to unavoidable circumstances such as illness. In the exercise condition, participants will perform 20 minutes of cycling exercise on a cycle ergometer at an intensity corresponding to 60-70% of maximal heart rate while watching a neutral video. Cognitive performance will be assessed using the n-back task before and after exercise. In the seated rest condition, participants will remain seated at rest for 20 minutes while watching a neutral video. Cognitive performance will be assessed using the n-back task before and after the rest period.

Interventions/Control_2

Participants will complete the seated rest condition first, followed by the exercise condition after an interval. The interval between conditions will generally be 3-14 days, although the second session may be postponed due to unavoidable circumstances such as illness.

Plan to share IPD

After publication, de-identified individual participant data underlying the primary and secondary outcome analyses will be shared with researchers who have an appropriate research purpose and receive approval from the principal investigator.

IPD sharing Plan description

Data will be available following publication of the study results, with no predetermined end date. Data sharing requests will be reviewed on a case-by-case basis by the principal investigator based on the proposed research purpose, analysis plan, and any necessary ethical procedures. De-identified individual participant data necessary to achieve the aims of the approved proposal will be provided. The study protocol and analytic code will also be made available upon reasonable request. Requests should be sent to the principal investigator at the email address listed in this registration. Descriptions of variable definitions, units, and coding will accompany the shared data.

Other related information

The title used for ethical review was "Effects of Acute Exercise on Cognitive Function." A different scientific title is used in this registration to describe the study more specifically.
This study initially received approval from the ethics committee and subsequently underwent several protocol modifications based on a series of pilot experiments and refinements of the study procedures. The present registration is based on the latest version of the study protocol approved by the ethics committee in October 2025.
