Abstract: Objectives. To examine the effect of an acute bout of resistance exercise on cognitive performance in healthy middle-aged adults. Design. A randomized controlled trial design. Methods. Forty-one adults (Mage = 49.10 years, SD = 8.73) were randomly assigned to either resistance exercise or a control condition. The resistance exercise condition consisted of 2 sets of 10 repetitions for 6 exercises, and the control condition involved reading about resistance exercise for a time period approximating the duration of the exercise condition. The Stroop Test and the Trail Making Test (TMT) were completed at baseline and immediately following performance of the treatment. Results. Results indicated that resistance exercise significantly benefits speed of processing (Stroop Word and Stroop Color), and that there is a trend towards resistance exercise benefiting performance on an executive function task (Stroop Color–Word) that requires shifting of the habitual response. However, the results for the TMT were not significant which demonstrates that acute resistance exercise has a limited effect on inhibition. Conclusion. The present findings extend the literature by indicating that an acute bout of resistance exercise has a positive impact on automatic cognitive processes and on particular types of executive function in middle-aged adults.
