Summary
Physical activity levels influence motor imagery. High activity individuals showed better rhythmic imagery, suggesting a link between sedentary time and inaccurate motor imagery of maximum walking.
Area of Science:
- Neuroscience
- Kinesiology
- Motor Control
Background:
- Motor imagery, the mental simulation of movement, is crucial for motor control and learning.
- Assessing motor imagery through rhythmic perception offers a novel approach to understanding movement representation.
Purpose of the Study:
- To investigate the relationship between errors in motor imagery of walking rhythm and actual physical activity levels.
- To introduce and validate a new motor imagery assessment based on rhythmic perception and its error (delta; ∆).
Main Methods:
- Participants were categorized into high activity (HA-Group) and low activity (LA-Group) based on daily sitting time.
- Motor imagery was assessed using visual, auditory, and mental comfortable/maximum walking rhythms, measuring deviations (∆) from actual rhythms.
Main Results:
- The HA-Group demonstrated significantly higher ∆ visual rhythm and ∆ mental comfortable walking rhythm.
- Conversely, the HA-Group exhibited significantly lower ∆ auditory rhythm and ∆ mental maximum walking rhythm compared to the LA-Group.
- After adjusting for covariates, the HA-Group still showed significantly lower ∆ mental maximum walking rhythm.
Conclusions:
- The accuracy of maximum walking imagery is associated with sedentary time.
- Inaccurate mental representation of maximum walking may correlate with prolonged sitting or inactivity.
