Key result
Acute resistance exercise with moderate intensity (60% 1RM) beneficially influenced task switching, whereas attention performance increased after both moderate and vigorous intensity exercise.
Why the study?
Beneficial acute effects of resistance exercise on cognitive functions may be modified by exercise intensity or habitual physical activity.
Does resistance exercise intensity and workload improve acute cognitive function in young adults?
Comparison
Four resistance exercise interventions across intensities (60%, 75%, 90% 1RM) and workloads
Design
Randomized crossover trial
Follow-up
Immediately after exercise

Does resistance exercise intensity and workload improve acute cognitive function in young adults?
Acute resistance exercise at moderate intensity (60% 1RM) optimally improves task switching, while both moderate and vigorous intensities improve attention, independent of habitual physical activity levels.
Engeroff et al. (2021) reported an RCT. Resistance exercise vs. Pre-exercise baseline was evaluated on Cognitive attention (TMTA), task switching (TMTB), and working memory. Acute resistance exercise with moderate intensity (60% 1RM) beneficially influenced task switching, whereas attention performance increased after both moderate and vigorous intensity exercise.
