AIMS: Heart rate recovery after exercise (HRR) is an estimate of autonomic modulation of the heart, and has beenshown to be inversely associated with type 2 diabetes. Type 2 diabetes is associated with decreased maximaloxygen consumption (VO2max). Aim of our study was to assess the relationship between HRR and VO2max insedentary patients with type 2 diabetes.METHODS: Maximal exercise testing to determine VO2max (ml ∙ Kg-1 ∙ min-1) was performed in 16 sedentarypatients with type 2 diabetes (DP) and in 16 age-matched sedentary healthy controls (HS). HRR (bpm) 2 min aftercessation of the exercise was recorded. Simple linear regression was used to assess the relations between HRRand VO2max.RESULTS: VO2max and HRR were significantly lower in DP compared to HS (P = 0.002 and P = 0.008respectively). A correlation between HRR and VO2max has been found, stronger in DP (r = 0.672, P = 0.004) thanHS (r = 0.620, P = 0.01).CONCLUSIONS: Our study suggests that regular physical activity aimed to improve the levels of VO2max insubjects with diabetes may improve the HRR and reduce the risk of cardiovascular events.
