This study investigates how motor strategies adjust under different accuracy constraints, finding that gravity-related effort minimization decreases when high accuracy is required.

The paper analyzes phasic EMG activity during arm movements to show how the CNS optimizes gravity effects across movement speeds and directions.

The study finds that the dominant arm minimizes muscle effort more effectively than the non-dominant arm during vertical arm movements, as indicated by directional asymmetries and reduced negative epochs in muscular activity.

This study compares motor lateralization in young and older adults during vertical arm movements, finding reduced lateralization in older adults.

This study examines motor planning of vertical arm movements in young and older adults, finding that effort optimization persists with aging but shows increased directional asymmetry.
