The sport of orienteering, combining exercise with challenging navigation, may be better for the brain than exercise alone, according to new research from kinesiologists at McMaster University.
In fact, the more vigorous the orienteering, the greater the benefits, which could be used to fight cognitive decline, dementia and catastrophic diseases such as Alzheimer’s.
The study, a follow-up to research published in 2023, examined the cognitive effects of orienteering at different intensity levels.
The researchers focused on orienteering because it requires athletes to navigate quickly through a series of checkpoints across an unknown terrain, using only a map and compass.
Through focused attention and deduction, orienteers use spatial information to make quick decisions while moving through a course.
This form of navigation employs the hippocampus, an area of the brain more susceptible to age-related decline than others. Degeneration in this region can impair learning, memory and spatial cognition.
“Remarkably, even a single orienteering session improved spatial memory in our study participants,” says lead author Emma Waddington, a graduate student in the Department of Kinesiology at McMaster who conducted the work with colleagues at Western University. “This suggests that participating in orienteering, even infrequently, could enhance spatial abilities, potentially delaying their decline with age.”
For the study, recently published in the journal PLOS One, groups of active, healthy young adults with no orienteering experience navigated a course on the McMaster campus, some by walking and others by running. A control group exercised vigorously without having to navigate.
Using blood samples, researchers measured participants’ lactate levels, an indicator of exercise intensity, and brain-derived neurotrophic factor (BDNF), a promoter of brain plasticity. They tested memory performance before and after the sessions.
Researchers found that running increased lactate, BDNF and memory to a greater degree than walking, with particular benefits for spatial memory among those running while orienteering.
Losing the ability to find one’s way is among the earliest and most common symptoms of Alzheimer’s disease, which affects half of all afflicted individuals, even in the mildest stage of the disease.
“With no known cure for dementia, preventative measures that can help to stave off age-related cognitive decline are essential,” says Jennifer Heisz, Canada Research Chair in Brain Health and Aging at McMaster University, who supervised the research.
She says modern-day dependency on vehicles featuring navigation guided by GPS may mean that most people don’t use their wayfinding skills, possibly leading to spatial memory deficits and a diminished sense of direction, which orienteering could revive.
The researchers say exploring the long-term effects of orienteering on human cognition and in different age groups is an important area for future study.
