Notes.
ACC was defined as the ratio between the number of correct responses and the total number of trials presented, calculated from the sum of correct responses. Trials in which the participants missed the target, pressed the button incorrectly, or waited longer than the stimulus presentation in order to improve their stop ACC were excluded as errors.
- SSRT
- stop-signal reaction time
- RT
- reaction time
- ACC
- accuracy
- NST
- never stop task
- MST
- maybe stop task
- Stop Acc
- probability of a successful stop in the MST
Post-hoc analysis results: no-exercise PD vs. healthy control group. ††p < 0.01, †††p < 0.001; exercise PD vs. healthy control group: # p < 0.05, ## p < 0.01, ### p < 0.001; exercise PD vs. no-exercise PD group: ∗p < 0.005, ∗∗p < 0.01, ∗∗∗ p < 0.001.
