Weight training is one of the most beneficial activities you can do for your health. And it appears that lifting weights may do more than just build muscle; it could also enhance cognitive function, particularly in older adults. A recent study published in Scientific Reports examined the effects of barbell resistance exercises on cognitive performance, specifically information processing speed and inhibitory control.
Participants aged 50 to 65 engaged in a single session of resistance exercises, including squats, presses, and deadlifts, performed at 75% of their one-repetition maximum. The results were compelling: participants showed significant improvements in information processing speed, as measured by the Stroop task. This suggests that lifting weights can enhance the brain’s ability to process information quickly, a critical factor in overall cognitive health.
Interestingly, the study also found that resistance exercise reduced conflict-related neural activity, indicating improved brain efficiency in managing competing stimuli. However, the study did not find a significant change in inhibitory control, which is the ability to resist impulses and distractions.
These findings underscore the cognitive benefits of resistance training, particularly in aging populations. By improving processing speed and reducing mental conflict, strength training could play a crucial role in maintaining cognitive health and longevity.
