| Abstract: | IntroductionRegular physical activity (PA) practice represents a key component of obesity treatment.ObjectiveBased on self-determination theory (SDT), this cross-sectional study aimed to explore the motivational characteristics associated with PA practice among obese adolescents.MethodOne hundred and five overweight or obese adolescents (mean age = 15 years old, SD = 2.69) were questioned about their level of PA, motivational regulations toward PA and level of satisfaction of basic psychological needs.ResultsData revealed that satisfaction of autonomy and relatedness needs is positively associated with autonomous forms of motivation (e.g., for integrated regulation β = .44; and 0.35, respectively, p < .01). Otherwise, non-satisfaction of the needs of autonomy and competence is associated with the most controlled forms of motivation (e.g., for external regulation β = −.27, p < .01; and −.18, p < .05, respectively). In turn, a high level of identified regulation, a low level of external regulation and a high level of satisfaction of the need for competence are associated with weekly PA (β = .28; −.19 and .24, respectively, p < .05).ConclusionSDT appears as an interesting theoretical framework to explore motivational antecedents of PA among obese adolescents. |
