RealFeedApp Split-belt walking study reveals muscle adaptation mechanisms
Three days of split-belt walking training decreased reactive muscle recruitment in younger adults while increasing context-specific patterns, but these changes were minimal in older adults. Researchers recorded surface electromyography from ten leg muscles and applied linear regression to separate activity into reactive and context-specific components.
- Field
- the brain and neuroscience
- What they did
- Researchers investigated how aging affects people's ability to react to environmental changes and to recall specific movements learned through practice. They compared young and older adults who trained on a treadmill with uneven belt speeds.
- Why it matters
- The results show that older adults find it harder to adapt quickly to new conditions, but practice helps them better recall established movements.
