Individual patterns of positive–negative affect (PNA) were studied in 46 ice hockey players, ages 15–17 years. Recall idiographic scaling following the methodology of the individual zones of optimal functioning (IZOF) model was used to identify subjective emotional experiences related to each player’s successful and unsuccessful game performance. Individual zones for each emotion were then estimated using Borg’s Category Ratio (CR-10) scale. Different positive and negative emotions were functionally facilitating (20.5%), debilitating (25.3%), or both (54.2%). Significant differences were revealed only at intra- and interindividual but not at the group level. Optimal and nonoptimal zones for different emotions in different players were also individual. The data support and extend Hanin’s IZOF model to the content and intensity of PNA in ice hockey. Implications for the development of sports-specific scales, idiographic assessments, and application of the IZOF model in team sports are suggested.
