dc.description.abstract	Extrinsic motivation via monetary reward incentivizes behavior. Data on how an incentivization encourages participants to push beyond their perceived limit are equivocal. This study aimed to determine if physically active, healthy, young adults could be influenced by an unexpected monetary reward to extend their time-to-task failure (TTF) cycling performance. Participants completed a control and reward TTF session in the heavy intensity domain of exercise (HVYTTF), and 1 min after, a TTF in the extreme domain (EXTTTF). The reward session involved an unexpected incentive offered 1 min before expected task failure during the HVYTTF. Neuromuscular (NM) assessments before and after the TTFs and the EXTTTF performance itself were used to evaluate performance fatigability. The unexpected incentive significantly increased the HVYTTF (46+/-16 min, 53+/-22 min; p =0.01) and reduced the EXTTTF (68+/-17 s, 57+/-17 s; p =0.03). Isometric NM assessments showed no condition effect or interactions. Significant time effects from baseline compared to post-HVYTTF and post-EXTTTF existed, respectively, for: i) IMVC: control, 601N, 414N, 413N (p <0.001); reward, 616N, 418N, 415N (p <0.001); ii) Db10:100: control, 0.99, 0.73, 0.70 (p <0.001); reward, 1.00, 0.74, 0.72 (p <0.001); and iii) Qtwpot: control, 177N, 109N, 110N (p <0.001); reward, 174N, 110N, 99N (p <0.001). VA showed no time effect from baseline to post-HVYTTF and post-EXTTTF: control, 90%, 90%, 87%; reward, 89%, 86%, 84%, respectively. These findings indicate that a monetary reward that increased the HVYTTF resulted in a reduced EXTTTF. The reduced performance during the dynamic task was not captured by isometric NM assessments.
