Strength training improves memory: new research findings.

According to ТСН: Visiting the gym not only strengthens muscles but can also significantly improve memory and cognitive functions. This is confirmed by the results of new research.

Scientists from the USA found that even a single session of strength training lasting over 40 minutes can dramatically enhance long-term memory in healthy adults.

The impact of strength training on memory

Researchers from Purdue University in Indiana analyzed 121 adults aged 18 to 50. The participants were divided into two groups:

1. Training group: performed moderate strength exercises (bench press, lat pulldown, bicep curls, leg press, tricep extensions, and leg extensions) for 42 minutes.

2. Control group: watched a video of other participants performing the same exercises.

Before and after the experiment, participants underwent testing for brain electrical activity and provided blood samples.

“The results demonstrate that acute strength training positively affects executive functions, improving information processing speed and working memory, as well as neuroelectric function,” the scientists noted.

It was found that the group performing weight exercises showed improved reaction times associated with working memory compared to the control group. Researchers believe that similar effects may be produced by other forms of strength exercises, such as squats or leg curls.

Mechanism of influence: lactate and blood pressure

Although the exact mechanism of how strength training impacts working memory is still being studied, scientists suggest that increased blood lactate levels and blood pressure following physical activity may enhance the speed of “executive functions,” which, in turn, boosts cognitive performance.

Since cognitive ability tests were conducted immediately after the exercises, the duration of this positive effect remains unclear.

“Clinically, these findings support the integration of strength training into training programs to achieve acute benefits for executive functions,” the researchers concluded in the journal Psychophysiology.

Strength training for brain health

This study confirms previous scientific works that indicated a link between physical activity and the preservation of cognitive functions.

• Dementia prevention: earlier, Spanish scientists found that increasing physical activity to two and a half hours per week between the ages of 45 and 65 reduces the risk of developing toxic amyloid protein in the brain, which is associated with Alzheimer's disease symptoms.

• Biological age: it has also been shown that lifting weights three times a week can lower a person's biological age by nearly eight years.

WHO and MOH reminders: The World Health Organization recommends that adults engage in physical activity for at least 150 minutes a week at moderate intensity or 75 minutes of vigorous exercise. It is also important to include strength exercises for all major muscle groups (legs, back, and abdomen) at least two days a week.

These results highlight the importance of physical exercise not only for physical but also for mental health. Incorporating strength training into the daily routine can be a simple step towards improving memory and cognitive abilities.
