The bilateral deficit results from the maximum voluntary force of a bilaterally performed task being smaller than the sum of the maximum voluntary force of the unilaterally performed tasks. It is underlain by the limitation of the neural drive during maximum bilateral contractions and has been hypothesized to reflect the inability to fully activate high threshold motor units. Because high threshold motor units atrophy in older adults, a smaller bilateral deficit in older adults compared to… CONTINUE READING
