Why the study?

It was proposed that exercise density within a single bout of exercise may moderate the expression and magnitude of postexercise executive function benefits.

Does exercise density (low vs high density interval exercise) improve postexercise inhibitory control?

Population

25 participants

Comparison

High-density interval exercise vs low-density interval exercise vs non-exercise control

Follow-up

~5-min postexercise

Key result

Low-density interval exercise (2-min rest), but not high-density (1-min rest), produced a pre- to postexercise reduction in antisaccade reaction times.

Overview

Exercise density may moderate post-exercise inhibitory control gains; leaves open optimal timing before clinical or mechanistic trials.

Structured PICO

Does exercise density (low vs high density interval exercise) improve postexercise inhibitory control?

P
Population
25 participants who completed separate interval exercise conditions (high-density and low-density) and a non-exercise control.
I
Intervention
Interval exercise conditions: ten 1-min intervals of exercise (40% of 1 repetition max leg extensions at 0.25 Hz) interspersed with 1-min (high-density: HD) or 2-min (low-density: LD) of rest
C
Comparator
Non-exercise control
O
Outcome
Inhibitory control component of executive function assessed via antisaccade task reaction times prior to and following exercise (~5-min)surrogate

Low-density interval exercise, but not high-density, improves postexercise inhibitory control, suggesting exercise density moderates cognitive benefits.

Cite This Study

Mendes et al. (2026) studied this question. Interval exercise vs. Non-exercise control was evaluated on Pre- to postexercise reduction in antisaccade reaction times (RTs). Low-density interval exercise (2-min rest), but not high-density (1-min rest), produced a pre- to postexercise reduction in antisaccade reaction times.
