Anthropometric parameters, body composition dual X-ray absorptiometry , and maximal aerobic capacities maximal oxygen consumption [VO 2peak ] were assessed, and self-reported questionnaires were used to assess HR-QOL item short form survey , HP and PSP at baseline T0 and post-intervention T1. Results: Body weight There was a tendency for VO 2peak to increase from Keywords : High-intensity interval training, Quality of life, Health perception, Adolescents, Obesity.
Pediatric obesity, resulting mainly from a physically inactive lifestyle and inappropriate dietary habits, is becoming one of the major public health problems of the 21th century. The prevention and the treatment of obesity, which is considered a multifactorial disorder, requires effective multifaceted interventions.
Recently, Khammassi et al. Freitas et al. Interestingly, these HR-QOL benefits were greater in the group of adolescents who received psychological counseling. While most of the available studies used multidisciplinary interventions that included moderate-intensity aerobics plus resistance exercises, more recent studies compared the effect of different physical activity programs.
For instance, Lopera et al. Similarly, Rey et al. Although a lot of attention has been given to the use of high-intensity interval training HIIT as an effective strategy among adolescents with obesity, 16 - 18 to our knowledge, the psychological responses to this exercise modality in this population remains unknown.
In , Svensson et al. While both groups improved overall HR-QOL, greater effects were observed in the HIIT group, particularly regarding physical functioning, vitality and general health, improvements that were however not associated with changes in body mass of aerobic capacities. Since the achievement and maintenance of weight loss may rely mainly on the psychological responses to our interventions, it is of high importance to improve the assessment and understanding of the responses to HIIT in adolescents with obesity.
