The objective of the present study was to test the effect of fatigue on task performance in a tracking task performed with a computer mouse. Participants performed a two-minute tracking task twice before and once immediately after a fatiguing wrist extension protocol. Results indicate that the mean distance to the centre of the target and the standard error of the mean distance to the target were significantly larger after fatigue. The percentage of time on target was unchanged by fatigue. Subjects seemed to be able to meet the requirements of the task instruction despite fatigue, but it is likely that this was done at the expense of a higher muscular load.
