Abstract
The present study attempted to test whether the strongest effect of Psyching-up strategy on actual sprint performance can be observed when the strategy is used immediately (or almost) prior to performance compared to when there is a delay between PU and performance. To do so, 16 male sprinters (age 20.6 +/- 1.3 years, body mass 77.5 +/- 7.1 kg, height 180.8 +/- 5.6 cm) were enrolled in a counterbalanced experimental design in which participants were randomly assigned to 10 sessions (2 [Experimental condition: imagery vs. distraction] x 5 [Time intervals: No interval, 1 min, 2 min, 3 min, and 5 min]). Before performing the experimental tasks, participants rated: (a) the Hooper index, (b) their degree of self-confidence, and (c) after the completion of the experimental test; they rated their perceived effort. Findings showed that the imagery significantly improved sprint performance. Specifically, the imagery enhanced performance on the phase of acceleration (0-10-m) and on the overall sprint (0-30-m) when used immediately prior to performance and at 1-and 2-min-intervals but not for 3-and 5-min intervals. These findings support the hypothesis that the potential effect of the PU strategy on performance vanishes over time. The pre-experimental task Hooper- and self-efficacy indexes did not change across the 10 experimental sessions, reinforcing the view that the observed performance changes were directly caused by the experimental manipulation and not via any altered status of the athletes (self efficacy, fatigue/recovery, stress). The potential mechanisms underlying such a process and practical applications are discussed.
