Design outcomes
Primary
| Measure | Time frame |
|---|---|
| It is expected that adolescents who practice the exercise session at decreasing intensity will present a more positive affective response during and, especially at the end of the session, which will tend to provide a remembered pleasure with more positive valence, as well as a perception of a promising anticipated pleasure. Furthermore, this affective memory of the exercise may reverse valence after 30 minutes, due to the return to the basal state, as previously described (Solomon, 1980; Zenko et al., 2016). | — |
Secondary
| Measure | Time frame |
|---|---|
| More positive affective responses are expected in adolescents considered physically active and with a higher level of physical fitness. Furthermore, it is believed that the waist-to-height ratio and muscle mass index (BMI) may be variables that will interfere in the intensity-affect relationship, providing more positive responses in eutrophic individuals. It is also worth noting that previous preferences for exercise may moderate and/or mediate this relationship between exercise and affect in the population studied. Finally, socioeconomic factors may also interfere in the psychological perception of physical exercise. | — |
