Aerobic exercise modulates intracortical inhibition and facilitation in a nonexercised upper limb muscle.

ABSTRACT:

Background

Despite growing interest in the relationship between exercise and short-term neural plasticity, the effects of exercise on motor cortical (M1) excitability are not well studied. Acute, lower-limb aerobic exercise may potentially modulate M1 excitability in working muscles, but the effects on muscles not involved in the exercise are unknown. Here we examined the excitability changes in an upper limb muscle representation following a single session of lower body aerobic exercise. Investigating the response to exercise in a non-exercised muscle may help to determine the clinical usefulness of lower-body exercise interventions for upper limb neurorehabilitation.

Methods

In this study, transcranial magnetic stimulation was used to assess input-output curves, short-inte
