This study investigated the effect of acute multiple joint, structural barbell resistance exercise on information processing speed and conflict-related neural activity in older adults via a crossover, sham control, randomized control trial.

Barbell back squat, press, and deadlift for three sets of five repetitions with the weight closest to 75% of their estimated 1 repetition max. The participants were instructed to execute the movement with moderate speed (2s eccentric, 2s concentric, no pause in between). The rest period between sets and exercise movements was two to three minutes.
Participants completed a passive stretching exercise session for a similar duration of time as the resistance exercise (≈ 30 min) as sham intervention, which included 15-20 stretching movements twice, holding each for 30 seconds as recommended by ACSM.

Change of Information processing speed between resistance and stretching exercises
Choice reaction time of the Stroop test congruent condition. Unit: millisecond. Shorter reaction time means a better outcome.
Time frame: 5-30 minutes before and 10-35 minutes after each intervention.
Change of Inhibitory control between resistance and stretching exercises
Interference score of the Stroop test. Unit: millisecond. Smaller interference score means a better outcome.
Time frame: 5-30 minutes before and 10-35 minutes after each intervention.
Change of Conflict-related neural activity between resistance and stretching exercises
N2b (event-related potential)
Time frame: 5-30 minutes before and 10-35 minutes after each intervention.
Change of Neural activity related to locus coeruleus phasic response between resistance and stretching exercises
P3 (event-related potential)
Time frame: 5-30 minutes before and 10-35 minutes after each intervention.
