The present study aimed to determine the effects of acute concurrent exercise on inhibitory control via behavioral and event-related potential approaches and to examine its potential mediational role on lactate among younger adults. The main questions it aims to answer are: (1) Does acute concurrent exercise improve inhibitory control via behavioral and event-related potential approaches? (2) Does lactate play a potential mediational role in the effect of acute concurrent exercise on inhibitory control?
The present study aimed to determine the effects of acute concurrent exercise (CE) on inhibitory control via behavioral and event-related potential approaches and to examine its potential mediational role on lactate. Participants were randomly assigned to either a CE, aerobic exercise (AE), or control (CON) group. Participants in the CE group engaged in 12-minutes of AE (40%-59% of heart rate reserve \[HRR\]) coupled with 13-minutes of resistance exercise (1 set, with 75% of 10-repetition maximum, and 12 repetitions of 8 movements). The AE group participated in 25 minutes of AE (40%-59% HRR). Prior to and following exercise onset, participants in both the CE and AE groups completed a 5-minute warm-up and cool-down. Participants in the CON group read books for 35 minutes. Lactate concentrations were measured at timepoint of 0-, 17-, and 30-minutes relative to the treatment onset. Response time (RT) and accuracy in the Stroop test, as well as P3 amplitudes, were assessed before and after the treatment.

Inhibitory control
Inhibitory control was assessed using a modified computerized version of the Stroop test, which was administered through Neuroscan Stim2 software (Compumedics Neuroscan, Charlotte, NC). The test comprised four blocks, each consisting of 108 trials. Within each block, three types of trials were presented: neutral, congruent, and incongruent. The neutral trial involved displaying a square printed in red, green, or blue color. The congruent trial presented Chinese language prints in corresponding colors and words \[i.e., 紅 (RED), 綠 (GREEN), or 藍 (BLUE)\]. In contrast, the incongruent trial displayed Chinese language prints in different colors and words \[e.g., 紅 (RED) printed in blue color\]. Each block included 36 neutral trials, 36 congruent trials, and 36 incongruent trials. Participants were instructed to respond promptly and accurately to the color of the stimulus presented. Subsequently, the mean response time (RT) of correct trials and accuracy for each Stroop condition were examined.
Time frame: 30 minutes
Blood lactate
Blood lactate levels were assessed using fingertip samples measured with a lactate analyzer (The EDGE, Taipei, Taiwan) at three distinct time points: Timepoint 1 (prior to the commencement of treatment), Timepoint 2 (17 minutes after the initiation of treatment), and Timepoint 3 (30 minutes after the start of treatment).
Time frame: Timepoint 1 (prior to the commencement of treatment), Timepoint 2 (17 minutes after the initiation of treatment), and Timepoint 3 (30 minutes after the start of treatment).
