Outline of Final Research Achievements |
We investigated motor unit (motoneuron) activation properties in elderly in order to clarify the mechanisms of age-related muscle strength loss. Our study with new developed method, i.e. multi-channel surface electromyography, showed a characteristic motor unit activation properties in elderly subjects comparing with young subjects. Also, motor unit activation properties were significantly correlated with maximal force in elderly subjects, but not in young subjects. These results suggest that the motor unit activation properties also contribute to age-related muscle strength loss.
