Authors' conclusion
The present study suggests the importance of early screening for CVD risk factors in adolescent males with T1D. Also, it was revealed HIITR training compared to other training patterns, and cardiovascular health improves via enhancement of autonomic modulation, VO2peak, plasma lipids, and catecholamine levels.
Study context
- Population
- Adolescent boys with T1D (Fasting blood sugar (FBS): 274.66 ± 52.99, age: 15.2 ± 1.78 years, BMI = 19.61 ± 1.11) and healthy boys (FBS: 92.75 ± 5.22, age: 15.08 ± 1.67 years, BMI = 20.26 ± 2.66)24 T1D, 12 healthy
- Participants
- 12 / 12 / 12
- Comparison
- HIITR vs no training in boys with T1D; healthy controls
- Diabetes Training (DT)n = 12
- Diabetes Control (DC)n = 12reference
- Healthy Control (HC)n = 12
- Outcome
- HRV (24 h), blood glucose and plasma biomarkers
- Follow-up
- 12 weeks

Main finding
As reported in the abstract
HRV, VO2peak, HDL-C, NEP, HbA1c, FBS
- Heart rate variability (HRV) parameters, VO2peak, HDL-C and norepinephrine (NEP) significantly improved by exercise training
- p < 0.001
- Hemoglobin A1c (HbA1c) and FBS significantly reduced by exercise training
- p < 0.001
Further findings
Baseline differences, T1D groups vs HC
- HRV, HbA1c, FBS, VO2peak, NEP and HDL-C differed significantly between both T1D groups and HC
- P < 0.001
- BMI, LDL-C, TC and TG similar in all groups
Correlation of LF/HF ratio change with VO2peak change
- Negative significant correlation between LF/HF ratio difference and VO2peak difference (post minus pre)
- P < 0.001
