The study aimed to investigate the effects of acute exercise with high (HE) and low (LE) cognitive demand exercise on working memory performance and neurophysiological indices in young adults. Methods: The present study applied a three-arm crossover randomized design, 31 participants completed three 20-minute conditions: HE, LE and active control (AC). Before and after the exercise intervention, working memory was assessed using 2-back task (reaction time and accuracy), the neurophysiological indices was measured using P300 (amplitude and latency). Results: The present study found a significant reduction in 2-back reaction time following both HE ( p =.005, d = -0.542) and LE ( p =.005, d = -0.423) compared to AC, with no differences between HE and LE. Futhermore, the shortening of P300 latency was significantly greater in HE than in LE ( p = .039, d = -0.419) and AC ( p < .001, d = -0.731), while P300 amplitude did not differ among conditions. Conclusions: The present study suggests that 20 minutes of moderate-to-vigorous interval training enhanced working memory in young adults, regardless of cognitive demand. A shorter P300 latency in the high-demand condition, however, indicates that cognitive demands during exercise may influence neural efficiency.
