GLYCEMIC SAFETY OF A MAXIMUM OXYGEN CONSUMPTION TEST IN TYPE 1 DIABETICS AND THEIR CORRELATION WITH HEALTH METABOLIC PARAMETERS

Resumo

To verify the glycemic safety of a maximal cardiorespiratory test (V?O2max) in T1D and correlate the maximum oxygen uptake values obtained with metabolic control parameters such as glycaemia, glycated hemoglobin, time of diagnosis (TD) and fat (body [GC] and visceral [GV]). The cross-sectional study evaluated 10 T1DM (3 women) (age 24.9 ± 7.5 years; time of diagnosis 11.5 ± 7.4; body mass index 22 ± 2 kg/m2). Metabolic glycemic control variables (before and after), glycated hemoglobin (HbA1c), time since diagnosis and total and visceral fat were collected. The CENESP maximum test protocol was used on the treadmill with direct maximal oxygen uptake (V?O2max). Normality test, paired t-test and correlations (p <0.05) were performed. In the results, blood glucose pre 189 ± 67 mg/dL and post 172 ± 66 mg/dL (p = 0.140). The V?O2max with a regular average score for men and women (37.4 ± 6.6 ml.kg.-1 min-1). There was a negative and almost perfect correlation with TD, GC and GV (p = 0.028; p <0.000; p <0.000). We conclude that is possible to perform a CENESP maximal T1D test with glycemic safe. However, TD, GC, and GV negatively interfere with cardiorespiratory fitness.
