Effects of different goal orientations and virtual opponents performance level on pacing strategy and performance in cycling time trials

We investigated the effects of different performance goals (best time vs. beat the opponent) on pacing behaviour during a 10-km cycling race and explored the influence of different performance level of opponents on ratings of perceived exertion (RPE), affective feelings and self-efficacy. Thirteen cyclists performed two time-trials (TT) and two races against a faster (FAST +6%) or a slower (SLOW –3%) virtual opponent. Power output (PO), RPE, affective feelings and self-efficacy were recorded at each kilometer point. Race average and race phases\ud [starting (P1= first kilometer); first half (P2=2nd to 5th km); second half (P3=6th to 9th km) and final sprint (FS=last kilometer)] were analyzed. There was no difference in performance, assessed by race time between conditions (p=0.84). PO during TT was lower in P3 compared to FS (p=0.03; ES 0.6; 90%CI 0.4 to 0.7). In SLOW and FAST, PO was higher in P1 compared to other phases (p
