We investigated the relationship between changes in motor cortex and corticospinal tract excitability and different characteristics of isotonic contraction. The characteristics included contraction intensity (strong and weak), frequency (high and low), and periodicity (periodic and discrete). Excitability of the motor cortex and corticospinal tract was higher during periodic isotonic contraction than during discrete isotonic contraction. The effects of contraction intensity and frequency remain controversial.
