Motor variability during sustained contractions increases with cognitive demand in older adults

Motor variability during sustained contractions increases with cognitive demand in older adults

To expose cortical involvement in age-related changes in motor performance, we compared steadiness (force fluctuations) and fatigability of submaximal isometric contractions with the ankle dorsiflexor muscles in older and young adults and with varying levels of cognitive demand imposed. Sixteen you...
