Key result
Moderate resistance training for 12 weeks in type 2 diabetes patients did not change cardiac autonomic function (p>0.05) but decreased resting double product (∆= -990.55 ±1154.91).
Why the study?
To evaluate the influence of a resistance training protocol on autonomic heart rate function and cardiovascular variables in patients with DM-2.
Does resistance training improve cardiac autonomic function and cardiovascular variables in patients with type 2 diabetes?
Does resistance training improve cardiac autonomic function and cardiovascular variables in patients with type 2 diabetes?
p-value: p=>0.05
A 12-week moderate resistance training program in patients with type 2 diabetes did not change cardiac autonomic function but decreased resting myocardial overload as measured by double product.
No autonomic changes but lower resting double product with resistance training; leaves open benefits in type 2 diabetes.
Objective: to evaluate the influence of a RT protocol on the function autonomic heart rate and cardiovascular variables in patients with DM-2. Methods: 9 patients with DM-2 participated in the study. After initial evaluation, data collection was performed regarding the RR intervals (iR-R) of the frequency heart rate (HR) and systolic (SBP) and diastolic (DBP) blood pressures while performing Function Tests Autonomic Cardiac Respiratory Sinus Arrhythmia Accentuating Maneuver (ABR), Active Postural Maneuver (APM), Valsalva Maneuver (ValM), Handgrip Test and the HR, SBP, DBP and double product (DP) data were also analyzed under the pre and post RT. RT was applied with moderate intensity of 60% of 1RM, exercises for lower and upper limbs, twice a week for 12 weeks. Results: the variations of the calculated indices for the TFACs did not show differences significant statistics (p>0.05). PAS, PAD and FC also showed no difference However, the PD showed a decrease at rest (∆= -990.55 ±1154.91) Conclusions: the moderate RT with 12 weeks, in patients with DM-2, does not promote any change in the function autonomic cardiac output but decreases myocardial overload by attenuating PD at rest.

Britto et al. (2022) studied Type 2 diabetes (n=9). Resistance training vs. Pre-training baseline was evaluated on Cardiac autonomic function and cardiovascular variables (p=>0.05). Moderate resistance training for 12 weeks in type 2 diabetes patients did not change cardiac autonomic function (p>0.05) but decreased resting double product (∆= -990.55 ±1154.91).
