“…Endurance athletes encounter many stressors (e.g., weather, temperature, equipment) before and during events (e.g., O'Neil & Steyn, 2007) that, depending on the athlete's appraisal of them (e.g., Martinent & Ferrand, 2015), could have helpful or harmful consequences. Research has shown that endurance athletes do experience harmful (i.e., dysfunctional) emotional responses such as anxiety, frustration, and discouragement in response to stressors before and during performance, as well as detrimental consequences to their motivation and focus of attention (McCormick et al, 2016). Other potentially harmful consequences of emotional responses are reduced confidence and concentration, and each of these consequences have implications for performance (Lazarus, 2000;Martinent & Ferrand, 2009;Vast, Young, & Thomas, 2010).…”
