To evaluate the effects of a progressive resistance training (RT) on cardiac autonomic modulation and on cardiovascular responses to autonomic stress tests in patients with Parkinson disease (PD).
30 patients with PD were randomly divided into 2 groups: a progressive RT group (PDT) who performed 5 resistance exercises, 2 to 4 sets, 12 to 6 repetitions maximum per set, a control group (PDC), and, a group of paired healthy control subjects without PD (HC). PDT and PDC groups were evaluated before and after 12-weeks. HC group was evaluated once. Autonomic function was assessed by spectral analysis of heart rate (HR) variability and cardiovascular responses to autonomic stress tests (deep breathing, Valsalva maneuver and orthostatic stress.
Compared with baseline, normalized low-frequency component of HR variability decreased significantly after 12 weeks in the PDT group only. Similar result was observed for systolic blood pressure fall during orthostatic stress that also reduced only in the PDT group. In addition, after 12 weeks, these parameters in the PDT achieved values similar to the HC group.
