A new study conducted by scientists at Purdue University has revealed an effective method for enhancing memory and improving brain function.
According to the journal Psychophysiology, the study found that a single 42-minute session of strength-training exercises significantly improves memory activation and speeds up information processing in the brain.

The study involved 121 healthy adults aged 18 to 50, divided into two groups. The first group performed two sets of 10 repetitions of strength-training exercises—bench press, rowing, bicep curls, and leg press—using 65–75% of each participant’s maximum weight. The second group simply sat and watched a video of the same exercises.
After the workout, participants completed tasks related to response inhibition and working memory at a faster pace, without any reduction in accuracy. On a neurological level, the exercises reduced the latency of the P3 component—an electrophysiological marker of cognitive processing speed—indicating that the brain handled the tasks more quickly than before the workout.
Physiological changes were also observed among those who exercised, including increased lactic acid levels and a significant rise in systolic blood pressure.
Analysis showed that this short-term increase in blood pressure partially explained the faster reaction times in cognitive tests, suggesting that the effect on the brain may be linked to heightened alertness and improved attentional regulation.
The researchers noted that the impact of exercise on memory was immediate, as testing occurred directly after the workout. However, it remains unclear how long this effect lasts or how intense strength training may influence individuals with chronic health conditions.
