Motor unit firing rate

upin humans1

1 study

  1. Motor unit firing rate is associated with motor unit recruitment threshold in humans (rs = 0.457, p < 0.001).

    “Changes in the MU firing rate following the exercise were correlated with the MU recruitment threshold in the older group (p < 0.001, rs = 0.457)”
