A groundbreaking study published in Neurology reveals a strong link between cardiovascular fitness in young adulthood and cognitive function decades later. Researchers followed 2,747 participants for 25 years, assessing their cardiorespiratory fitness via treadmill tests and later evaluating memory, processing speed, and executive function. The results demonstrated a significant correlation: better initial cardiovascular fitness predicted better cognitive performance in middle age. For every extra minute on the treadmill at age 25, participants recalled more words and performed better on psychomotor speed tests at age 50. Slower decline in treadmill performance over 20 years also correlated with better executive function. These modest but meaningful cognitive advantages exceed typical age-related decline and suggest a reduced risk of dementia. The study strongly advocates for prioritizing regular cardiovascular exercise from a young age to safeguard long-term brain health. This emphasizes the vital role of activities like running, swimming, and cycling in protecting cognitive abilities and potentially reducing dementia risk.

The link between cardiovascular exercise and memory in young adults
New research suggests that engaging in cardiovascular exercise and memory-boosting activities during young adulthood may have long-term benefits for cognitive function later in life. The study, published in the journal Neurology, found that young adults who performed better on treadmill tests of cardiorespiratory fitness were more likely to maintain better memory, processing speed, and executive function when tested 25 years later in middle age.
The study involved 2,747 healthy participants with an average age of 25 at the start of the study. They underwent treadmill tests to measure their cardiorespiratory fitness level, which assesses how well the body transports and uses oxygen during exercise. These tests were repeated 20 years later. Cognitive assessments were then conducted 25 years after the initial baseline to evaluate verbal memory, psychomotor speed (the relationship between thinking and physical movement), and executive function.
How cardiovascular exercise and memory performance are connected
The results showed that for every additional minute a participant was able to complete on the treadmill test at the start of the study, they correctly recalled 0.12 more words on the memory test and replaced 0.92 more numbers with symbols on the psychomotor speed test 25 years later. Those who experienced smaller decreases in treadmill time over the 20-year period also performed better on the executive function test, demonstrating better ability to name the ink colour of words rather than reading the word itself.
The researchers noted that the cognitive differences associated with better cardiovascular exercise and memory function, while modest, were larger than would be expected from one year of normal aging. Other studies have shown that these types of cognitive tests can be predictive of future dementia risk, with every additional word recalled on a memory test linked to an 18% reduced risk of developing dementia within 10 years.
The long-term impact of cardiovascular exercise and memory preservation
“These findings are likely to help us earlier identify and consequently prevent or treat those at high risk of developing dementia,” the researchers concluded. The results underscore the importance of maintaining a physically active lifestyle, especially during young and middle adulthood, to support long-term brain health and cognitive function.
By engaging in regular cardiovascular exercise and memory-enhancing activities such as running, swimming, biking, or aerobic fitness classes, young adults may preserve critical thinking skills and reduce their risk of cognitive decline and dementia later in life. The study highlights yet another compelling reason to prioritize overall physical fitness and heart health from a young age.
Conclusion
The evidence is clear: cardiovascular exercise and memory function are closely linked, with early-life fitness playing a significant role in long-term cognitive health. Regular cardio workouts like running, cycling, or swimming can help protect critical thinking skills and may even reduce the risk of dementia.
