Physical activity level and cardiorespiratory fitness in adolescents with type 1 diabetes mellitus: response in lipid profile

Objective: to analyze the relationship between regular physical activity, cardiorespiratory fitness, and lipid profile of adolescents with Type 1 Diabetes Mellitus (T1DM). Materials and Methods: 32 adolescents with T1DM (age 13.1 +/- 1.9) intentionally selected participated. The lipid profile, anthropometry, and composition (DXA), physical activity level (PAL), and cardiorespiratory fitness (VO2max) were evaluated. The data were analyzed in the software and SPSS, adopting an alpha error of 5% for statistical significance. Results: There was a significant difference for the percentage of fat with higher values for girls (p=0.192) and higher values of VO2max for boys (p=0.001), divided into groups (active and sedentary adolescents) there was a significant difference in the variables moderate to vigorous physical activity (MVPA) (p=0.002), triglycerides (TG) (p=0.024) VO2max (p=0.018). It was also observed a negative and moderate correlation between MVPA and TG (p=0.018), positive and moderate correlation between MVPA and VO2max (p=0.452), a negative and strong correlation between VO2max and total fat (p=0.856), negative and moderate correlation between VO2max and TG (p= -0.527). Conclusion: There is an inverse relationship between cardiorespiratory fitness, TG, and total fat percentage in adolescents with T1DM. As for PAL, physically active adolescents presented better lipid levels, better body composition, and VO2max in comparison with sedentary adolescents.
