A team of researchers from Huazhong University of Science and Technology (China) and the University of Sydney (Australia) has engaged nearly half a million participants in a 13-year study. The results revealed that cycling is associated with a lower risk of developing dementia.
The study specifically demonstrated that frequent bike rides from point A to point B can reduce the likelihood of cognitive disorders and age-related dementia. This seems to occur because cycling activates a part of the brain linked to memory functions.
The extensive work of the scientists confirmed the idea that regular moderate exercise and maintaining brain activity can protect against neurodegeneration. “The results of this cohort study indicate a connection between active modes of transportation, the onset of dementia, and brain structure,” the researchers noted in their report.
How Was the Study Conducted?
By examining health data from the UK regarding nearly half a million individuals with an average age of 56, the researchers sought to find a link between the most common modes of transportation among participants and the development of any form of dementia. The scientists categorized modes of transportation into four groups: inactive (car and public transport), walking, mixed transportation (inactive transport and walking), and cycling (including using a bike alongside other modes of transport).
The data analysis showed that compared to inactive participants, cyclists had a 19 percent lower risk of developing dementia from any cause, and a 22 percent lower risk of developing Alzheimer’s disease. The risk of dementia among cycling enthusiasts under the age of 65 was 40 percent lower, while the risk for older cyclists was 17 percent lower.
“Our results indicated that active travel, particularly cycling, may be associated with a lower risk of developing dementia among middle-aged and older adults,” the team wrote.
The development of a complex condition like dementia is influenced by a variety of factors, as reported by Science Alert. Previous studies have found a connection between spatial navigation abilities and brain volume. Interestingly, the new research revealed that cyclists tend to have a larger hippocampus—a part of the brain responsible for both long-term and short-term memory.
The team reminded us that dementia is becoming an increasingly serious issue as the global population ages. Approximately 55 million people worldwide suffer from it. Therefore, there is a need to explore new methods to combat the onset of dementia. Cycling is one such method—simple and accessible for many people.
The findings of the study were published in the journal JAMA Network Open.
