Orienteering as a Tool for Cognitive Research: An Implementation Guide.

The sport of orienteering combines physical activity with spatial navigation. Using only a map and a compass, the orienteer must locate a series of checkpoints over unfamiliar terrain using any navigational route they choose and while moving as quickly as possible. Although expert orienteers have superior spatial memory and navigational abilities, even a single session of orienteering can benefit cognition, suggesting that orienteering may be a promising way to train the brain.

Orienteering combines vigorous-intensity exercise with navigation to improve human cognition and increase brain-derived neurotrophic factor.

Exercise enhances aspects of human cognition, but its intensity may matter. Recent animal research suggests that vigorous exercise, which releases greater amounts of lactate, activates more brain-derived neurotrophic factor (BDNF) in the hippocampus and, thus, may be optimal for supporting cognitive function. The cognitive benefits of exercise may be further augmented when combined with cognitive training.

Monitoring lower limb biomechanical asymmetry and psychological measures in athletic populations-A scoping review.

Background: Lower limb biomechanics, including asymmetry, are frequently monitored to determine sport performance level and injury risk. However, contributing factors extend beyond biomechanical and asymmetry measures to include psychological, sociological, and environmental factors. Unfortunately, inadequate research has been conducted using holistic biopsychosocial models to characterize sport performance and injury risk.

Orienteering experts report more proficient spatial processing and memory across adulthood.

The closest surrogate to hunter-gather activity is the sport of orienteering, which naturally and simultaneously combines high-intensity interval exercise with navigation. Although human cognition can be improved across the lifespan through exercise and cognitive training, interventions like orienteering may be especially effective because they resemble activities engaged in by prehistoric humans during evolution. The present study tested whether orienteering experts have better hippocampal-dependent cognitive function than active, non-orienteering controls.

Recognition of Accented Speech by Cochlear-Implant Listeners: Benefit of Audiovisual Cues.

Objectives: When auditory and visual speech information are presented together, listeners obtain an audiovisual (AV) benefit or a speech understanding improvement compared with auditory-only (AO) or visual-only (VO) presentations. Cochlear-implant (CI) listeners, who receive degraded speech input and therefore understand speech using primarily temporal information, seem to readily use visual cues and can achieve a larger AV benefit than normal-hearing (NH) listeners. It is unclear, however, if the AV benefit remains relatively large for CI listeners when trying to understand foreign-accented speech when compared with unaccented speech.
