The results represent pairwise post hoc comparisons of Feeling Scale (FS) values. PC, perceived competence; AOI, awareness of interoceptive cues; HR, heart rate; x, interaction term; MICE, moderate-intensity continuous exercise; VICE, vigorous-intensity continuous exercise; HIIE, high-intensity interval exercise.

^aIn Model 1, we examined in-task (t₁, t₂) affective valence by including the levels subject, exercise session, and the crossed factor exercise modality (MICE, VICE, HIIE).

^bFor Model 3, we extended Model 1 by separately introducing the interaction term of one of three potential predictors (3a: PC, 3b: AOI, 3c: HR) with exercise modality (x exercise modality) as a fixed factor.
