Practical psychological interventions consistently improve endurance performance in published studies. Psychological skills training could therefore benefit an endurance athlete. There is more to learn, however, about how (i.e. mediating variables) and for whom (i.e. moderating variables) these interventions work.

Verbal encouragement and head-to-head competition can have a beneficial effect on endurance performance and should be controlled in experiments.

Mental fatigue has a negative effect on endurance performance.
