Table 1.
Models resulting from hierarchical fitting of valence, arousal, and reported perceived exertion (RPE) scores.
| Model | Effects | AIC | df | c2 | p |
|---|---|---|---|---|---|
| Saturated | Task, Measure, Time in task (and interactions) * | 4845.5 | 47 | ||
| Model 1 ** | Saturated minus Task*Measure × Time in task | 4843.0 | 43 | 5.48 | 0.241 (M1 > Saturated) |
| Model 2 | Model 1 minus Task*Measure | 4869.6 | 41 | 30.56 | <0.001 (M1 > M2) |
* All models also include internal physical load variables and their interactions with time in task and measure. ** Best-fitting model. AIC: Akaike Information Criterion.
