Effects of Resistance Training on Heart Rate Variability and Functional Functional Capacity in Menopaused women: a randomized clinical trial

INTERVENTION: A08.800.050 G11.427.410.698.277 N01.400.545.750 This is a randomized clinical trial, blinded by the statistical evaluator. Before randomization, participants must answer an anamnesis containing personal data, disease history; answer the international physical activity questionnaire (IPAQ) and the physical activity readiness questionnaire (PAR‐Q). Subsequently, they will perform two sessions of daily measurements at rest of HR, HRV and BP. From this, a session to familiarize the resistance training protocol will be scheduled. For data collection, anthropometric assessments will be performed (waist circumference, height and body mass), hemodynamic assessments (BP, HR and DP), autonomic assessments (active tilt test) using time domain metrics (rMSSD, SDNN , SDANN, PNN50), in the frequency domain (HF, LF, LF/HF) and non‐linear (SD1, SD2), functional capacity (Short Physical Performance Battery, 6‐minute walk test). Then, two groups of subjects will be randomly formed using an electronically generated block randomization sequence. Intervention group: 15 recreationally active women will perform minimal‐dose resistance training. Control group: 15 recreationally active women will participate in lecture cycles on the importance of physical exercise. Both groups will spend the same period of four weeks. Finally, the assessments will be repeated for the four‐week post‐intervention moment. CONDITION: G08.686.157.500 Postmenopause PRIMARY OUTCOME: To describe the effects of minimal‐dose resistance training on cardiac cardiac autonomic modulation compared to the control group. It is expected that the practice of minimal‐dose resistance training can be reinforced for HRV and consequently for the assessment of cardiovascular health measurements. Data will be automatically tested from shape change: two maintenance measures on non‐consecutive days, followed by active tilt, to assess automatic dysfunction caused by postural. These consultations will be repeated after 4 weeks of the protocol in both intervention and control groups. evaluated through linear indices in the time and frequency domain and non‐linear indices. As an analysis tool, it will be the Elite HRV application for mobile devices, whose data will be exported via email for use as HRV in the Kubios 2.2 software. SECONDARY OUTCOME: To describe the effects of minimal‐dose RT on functional capacity in menopausal women compared with the control group. It is expected that the practice of minimal‐dose resistance training may be beneficial for functional capacity in menopausal women. It will be evaluated through the Short Physical Performance Battery (SPPB) tests and the 6‐minute walk test. Measurements taken before and after the 4‐week intervention for both intervention and control groups. INCLUSION CRITERIA: untrained women; declare postmenopausal for > 1 year
