Impacto do videogame ativo nos níveis de proteína c-reativa e indicadores de adiposidade de adolescentes com excesso de peso: um ensaio clínico randomizado

Abstract

INTRODUCTION: the practice of physical activity has become indispensable for the prevention of cardiometabolic risk factors, especially during childhood and adolescence, a phase characterized by the adoption of sedentary habits, such as the use of video games daily. In an innovative way, games for video games were created, called active video games (VGA), which require the individual to perform body movements while playing. OBJECTIVE: to evaluate the effect of physical exercise promoted through the active video game (VGA) on the levels of ultra-sensitive C-reactive protein (CRP us) and indicators of adiposity in overweight or obese adolescents. METHODS: randomized Clinical Trial, carried out on 63 adolescents, from two municipal public schools in Campina Grande, aged 10 to 16 years, 11 months and 29 days, with overweight or obesity, allocated in two groups: 33 in the experimental group and 30 in control, the latter was adopted for comparative purposes. Randomization was carried out between schools, adolescents from the experimental school performed physical activity with the aid of one (XBOX360), three times a week, for 50 minutes a day, for a period of eight weeks, associated with gamification. Data collection instruments were used before and after the intervention: evaluation of anthropometric data, body composition, subscapular and tricipital skinfolds, socioeconomic data and blood level of CRP us. To evaluate the effect of the intervention on the outcome variables, between the groups, the t-student or Mann Whitney tests were used and within the same group, the paired t-student test or the Wilcoson test, depending on the distribution of the variable evaluated through the Kolmogorov-Sminorv test. The statistical program used was the Statistical Package for the Social Sciences (SPSS), in its version 22.0. In all analyzes, a significance level of 5% was adopted. RESULTS: of the evaluated adolescents, 41.3% had obesity, 56.5% high AC / height ratio and 11.1% high CRP. After the intervention, there was a significant decrease in BMI (p = 0.007) and a significantly lower value in the percentage of fat (p = 0.026) and in the level of the CRP us (p = 0.008). In addition, the control group showed a significant increase in the percentage of fat and CRP us. CONCLUSION: the use of VGA contributed significantly to a decrease in BMI and to lower values of fat percentage and the level of CRP in adolescents. However, it is suggested that future research be carried out for a longer period of intervention.
