“…Some research has been conducted on the forethought and performance stages, that is, on processes before and during endurance performance. For example, with consideration to the forethought stage, research has examined the effects of goal difficulty on improvements in middle-distance running times (Tenenbaum, Spence, & Christensen, 1999), and the influence of emotion suppression on cycling performance (Wagstaff, 2014). With consideration to the performance stage, research has examined the effects of using pre-selected attentional strategies, selftalk, imagery, relaxation, and combinations of these during performance (for reviews, see Brick, MacIntyre, & Campbell, 2014;McCormick et al, 2015).…”
