Effects of Acute Resistance Exercise on Executive Function: A Systematic Review of the Moderating Role of Intensity and Executive Function Domain

Abstract

Background Research has demonstrated that there is a beneficial effect of acute exercise on cognitive function; however, the moderators of the acute resistance exercise (RE) effect on executive function (EF) are underestimated. This systematic review aims to clarify the effects of acute RE on EF by examining the moderating effect of exercise intensity (light, moderate, and vigorous) and EF domains (inhibitory control, working memory, and cognitive flexibility), as well as their interactions. Methods The search strategy was conducted in four databases (PubMed, Scopus, PsycARTICLES, and Cochrane Library) prior to January 29, 2022. Included studies had to: (1) investigate acute RE in adults with normal cognition and without diagnosed disease; (2) include a control group or control session for comparison; (3) include outcomes related to the core EF domains; and (4) be published in English. The methodological quality of the included studies was judged according to the PEDro scale guidelines. Results Nineteen studies were included which included a total of 692 participants. More than half of the outcomes (24/42, 57.14%) indicate that acute RE had a statistically significant positive effect on overall EF. In terms of RE intensity and EF domain, moderate intensity acute RE benefited EF more consistently than light and vigorous intensity acute RE. Acute RE-induced EF benefits were more often found for inhibitory control than for working memory and cognitive flexibility. When considering moderators simultaneously, measuring inhibitory control after light or moderate intensity RE and measuring working memory or cognitive flexibility after moderate intensity RE most often resulted in statistically significant positive outcomes. Conclusion Acute RE has a beneficial effect on EF, observed most consistently for inhibitory control following moderate intensity RE. Future studies should include all exercise intensities and EF domains as well as investigate other potential moderators to enable a better understanding of the benefits of acute RE on EF.

Changes in EEG Activity and Cognition Related to Physical Activity in Older Adults: A Systematic Review

“…This lack of significant differences between high-and low-intensity exercise with regard to cognitive outcomes may be explained by the individual conditions of the participants, as well as the type and intensity of the PA. Evidence from a systematic review [48] evaluating the moderating effects of exercise intensity in healthy subjects aged 18 years or older indicated that moderate acute resistance exercise consistently shows beneficial effects on inhibitory control, while light or vigorous intensity resistance exercise yielded benefits in about 50% of cases, aligning with the results found in the present systematic review.…”

Acute effect of combined exercise with aerobic and resistance exercises on executive function

“…Furthermore, whether different modes of CE, which combine traditional sequential movement resistance exercise, are beneficial for exercise-induced cognitive function remains to be clarified. Furthermore, acute RE has garnered recognition as a significant and promising exercise modality within the realm of exercise and cognitive function ( Huang et al, 2022 ; Wilke et al, 2019 ); however, there are relatively few studies investigating the effects of RE on cognitive function compared to study targeted on AE ( Chow et al, 2021 ). Therefore, the present study specifically incorporates RE condition for comparison, aiming to address the limitations of previous studies in this area.…”

“…For example, a meta-analytic review of randomized controlled trials showed notable enhancements in executive functions, as assessed through standardized cognitive assessments, after a 12-week aerobic exercise program [120]. Likewise, resistance training programs have been found to have beneficial impacts on cognitive flexibility and processing speed, leading to faster reaction times and enhanced task-switching abilities in individuals who participate in resistance exercises that focus on major muscle groups [121]. Additionally, Tai Chi and yoga have been associated with improvements in overall cognitive function, especially in areas like verbal memory, visuospatial skills, and processing speed.…”
