title: Exploring affective responses to different exercise intensities in low-active young adolescents.
abstract: Adolescence provides a significant opportunity to influence attitudes toward activity. It has been proposed that affective responses are the first link in the hypothesized exercise intensity-affect-adherence chain. The aim of this study was to explore young low-active adolescents' affective responses to different exercise intensities using quantitative and qualitative methodologies. Participants completed 15 min of exercise at four exercise intensities: three set in relation to the participants' ventilatory threshold (above, at, and below) and one self-selected. Affective valence was measured before, during, and after exercise, and participants were interviewed about their responses. Patterns in affective responses in quantitative data support tenets of the dual-mode theory. Qualitative data were presented as four narrative stories, and dominant themes associated with affective responses were identified. Consideration of individual preferences in the prescription of exercise, prescribing exercise set below the ventilatory threshold, or encouraging adolescents to self-select exercise intensity could positively influence adolescents' exercise experiences.
