Selection of pace is determined before beginning an activity by the process of teleoanticipation. PURPOSE: The aim was to determine how temporal deception affected self-pacing and the time taken to run one mile, while considering psychological and physiological aspects. METHODS: Subjects (n=17, 18-22 yr.) completed a familiarization trial and three experimental trials (counterbalanced order) in which subjects ran one self-paced mile on a treadmill (0% grade) while the timer prominently displayed to subjects was manipulated (sped up 10% (SU), slowed down 10% (SD), or unaltered/control (C)). Mile time (actual, not manipulated/displayed time), stride rate and length, heart rate (HR), rate of perceived exertion (RPE), and affect were recorded for each trial. Treadmill displays were covered and subjects were informed of distance completed each quarter mile. Subjects were able to adjust treadmill speed at any time, except for 10 seconds at each quarter mile while stride characteristics were measured. A two-way repeated measures ANOVA was performed for all dependent variables evaluating the effects of the experimental timer and distance. Significance at pRESULTS:All data is presented as mean+SD. The mile times were unaffected by the timer displayed to subjects (C: 8:06+1:34, SU: 7:54+1:15, and SD: 7:57+1:13; p=.329 ). Regardless of timer intervention, RPE increased significantly at each quarter mile (pCONCLUSION:Subjects perceived that their performance was altered, yet this did not translate to a change in running speed. The selection of speed and RPE are so ingrained prior to beginning via teleoanticipation, that timer manipulation does not alter pacing strategies throughout a one-mile run.
