(1) Background: This study aimed to assess the influence of the COVID-19 pandemic on athletes’ and coaches’ experiences. Following the Dualistic Model of Passion and the Self-determination Theory, the objectives of this study were to investigate whether the COVID-19 pandemic and its restrictions affected athletes’ and coaches’ passion experiences, emotional experiences and basic psychological needs while engaging in their sport activities. Furthermore, the relationship between passion and emotional experiences as well as between passion and the basic psychological needs were explored; (2) Methods: 87 coach-athlete dyads, active at the recreational or competitive level in an individual sport, participated in the study. Using a cross-sectional dyadic design, athletes and coaches reported separately on their passion experience, emotional experiences and basic psychological needs in the previous two weeks; (3) Results: In total, 30 dyads were impacted by the COVID-19 pandemic, while 57 were not. Athletes’ obsessive passion as well coaches’ negative affect were larger in impacted dyads, while athletes’ positive affect was lower in that group compared to the not-impacted group. Moderated Actor–Partner Interdependence Models revealed that coaches’ obsessive passion was more strongly related to their negative affect in coach–athlete dyads that were not impacted by the COVID-19 pandemic than in dyads that were impacted. Furthermore, the harmonious passion of coaches was more strongly associated with athletes’ need satisfaction and need frustration in impacted dyads, while also the athletes’ harmonious passion in impacted dyads was more strongly associated with coaches’ need satisfaction; (4) Conclusions: Less positive outcomes and more negative outcomes were observed in both athletes and coaches that were impacted by the COVID-19 pandemic. On the other hand, the COVID-19 pandemic may have suppressed the negative effects of coaches’ obsessive passion on their negative affect, but strengthened the positive impact of coaches’ harmonious passion on the athletes’ need satisfaction and vice versa.
