In the first part of the book, psychological variables that can influence endurance performance, including pain, motivation, perceived effort, pacing, meta-cognition, emotions, and self-efficacy were introduced. The book will now move on to psychological interventions that aim to improve endurance performance. Although there is evidence to suggest that practical psychological interventions, such as goal-setting and imagery, can benefit endurance performance (McCormick, Meijen, & Marcora, 2015), we also need to consider the effect of psychological interventions on other related variables such as coping, emotions, and satisfaction with performance. In this second part of the book, the role of cognitive strategies, goal-striving, imagery, self-talk, and mindfulness will be outlined and evidence for the effectiveness of these interventions will be reviewed.
