Exercise can be prescribed as closed-loop bouts with a set task or time as the endpoint. Healthcare professionals may be able to create more individualized programs for clients by understanding their preference for, or performance in a specific endpoint oriented bout. Additionally, mental toughness has been reviewed as an important factor in determining success in high stress environments. The aim of this study was to examine differences in performance between task and time-oriented exercise bouts and to examine relationships between performance and levels mental toughness. A total of 14 participants (Males, N=10; Females, N=4) attended 3 sessions of data collection. Anthropometric measurements and mental toughness (via the Mental Toughness Scale) were assessed in session one. All subjects performed task and time-oriented running bouts during sessions 2 and 3 respectively. Heart rate, Ratings of Perceived Exertion, and treadmill speed were measured in each bout. Between-sessions differences reported significantly lower average RPE (p= 0.003), peak RPE (p= 0.022), and peak heart rate reserve (p= 0.017) for time-oriented sessions. Pearson correlation analyses reported no significant relationship between mental toughness and performance (p= 0.937). In conclusion, this study indicates significantly lower differences in performance variables in time-oriented bouts compared to task-oriented bouts.
