摘要：

CHRISTOU, E.A. Aging and variability of voluntary contractions. Exerc. Sport Sci. Rev., Vol. 39, No. 2, pp. 77-84, 2011. Older adults exhibit greater motor variability, which impairs their accuracy and function, compared with young adults. Low-intensity training that emphasizes muscle coordination reduces variability in older adults. Furthermore, a low amount of visual feedback minimizes age-associated differences in variability. We hypothesize that an intervention that combines muscle coordination and reduced visual feedback would be advantageous to improve motor control in older adults.
