Why the study?
Acute aerobic exercise benefits inhibitory control, but less attention has been devoted to the effects of varying intensity and duration with a predetermined exercise volume.
Does volume-matched acute aerobic exercise of varying intensities improve inhibitory control in late-middle-aged and older adults?
Comparison
Volume-matched LIE vs MIE vs HIE vs non-exercise reading control
Design
Crossover neuroelectric study
Key result
Acute aerobic exercise at low, moderate, and high intensities improved inhibitory control compared to control (p<0.005), with moderate intensity providing additional P3b amplitude benefits (p<0.01).

Acute exercise may aid inhibitory control in older adults; hypothesis-generating and should not yet change practice.
Does volume-matched acute aerobic exercise of varying intensities improve inhibitory control in late-middle-aged and older adults?
p-value: p=< .005
Volume-matched acute aerobic exercise across different intensities improves inhibitory control and modulates neural conflict monitoring in older adults, with moderate intensity providing additional benefits for attentional resource allocation.
Chu et al. (2023) studied Late-middle-aged and older adults (n=34). Acute aerobic exercise vs. Non-exercise reading control was evaluated on Inhibitory control (Stroop task behavioral performance and event-related potentials) (p=< .005). Acute aerobic exercise at low, moderate, and high intensities improved inhibitory control compared to control (p<0.005), with moderate intensity providing additional P3b amplitude benefits (p<0.01).
