| Affective Responses (pleasure / displeasure) In the present research project, affection is defined as descriptor of negative (unpleasure) and positive (pleasure) responses (Kwan and Brayan, 2010). This parameter is determined by means of the affective sensation scale (HARDY; REJESKI, 1989). This instrument is made up of an 11-point scale with unique, bipolarized items ranging from +5 (very good) to -5 ("very bad"). Instructions about the application of the instrument should be passed on to adolescents, so that they really understand what to "mark" according to their perception of affection. As an example, we have: "Please use this scale to indicate how your body is feeling during this exercise. If you are feeling the exercise as very good (pleasurable or comfortable), then the corresponding number will be "+5". If you are feeling very bad (unpleasant or uncomfortable), then the corresponding number will be "-5". If you are feeling neutral then the corresponding number will be "0" (HARDY; REJESKI, 1989). For anchoring purposes the instructions will be passed at each physical activity or behavioral counseling session and the adolescent should indicate with the thumb the value that corresponds to his / her affection at the moment. Adherence assessment Adolescent attendance will be monitored and recorded in all sessions in both groups. At the end of the 12 weeks the adolescent participation rate (adherence = [attendance to sessions / total number of sessions] * 100) will be calculated. In addition, the withdrawal rate of each of the experimental groups will be recorded. | — |

| Quality of life Scale used to evaluate quality of life - Pediatric Quality of Life Inventory 4.0 (PedsQL). This instrument consists of 23 items separated into 4 domains (physical composed of 8 items, emotional for 5 items, social for 5 items and school for 5 items), as well as Global Scores (23 items) and Psychosocial Scores (15 items). The questions are related to the items quoted in the last month, and the answers are punctuated according to the following options: (0 - it is never a problem; 1 - almost never a problem; 2 - sometimes it is a problem; - often a problem; 4 - almost always a problem). Negative questions are scored inversely on a scale of 0-100 (0-100; 1-75; 2-50; 3-25; 4-0); Thus, the higher the score, the better the quality of life Sleep quality For sleep quality analysis, the Pittsburgh Sleep Quality Index (PSQI) questionnaire (BUYSSE et al., 1989), which verifies sleep quality over the last month, will provide an index of severity and nature of the disorder ( TOGEIRO, SMITH, 2005). The questionnaire has 19 questions, grouped into seven components with weights ranging from 0 to 3. These are classified as related to sleep complaints, such as: subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency , Sleep disorder, use of sleeping pills, and daytime dysfunction. The scores of these seven components are summed to reach a score of 0 to 21 and the higher the score, the worse the quality of sleep. Thus, a PSQI score> 5 reveals that the individual presents great difficulties in at least two components or moderate difficulties in three or more components (BERTOLAZI; FAGONDES et al., 2011). Therefore, scores of 0 - 4 indicate good sleep quality, 5 -10 poor quality and above 10 sleep disorders. This instrument was validated in the Portuguese version (CHELLAPPA; ARAUJO, 2007). Blood analysis Approximately 8 ml (safe amount) of blood per trained nurse from each individual will be collected for the blood analysis to determin | — |
