ABSTRACT
OBJECTIVE:
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).DESIGN:
Randomized clinical trial.SETTING:
The Brazil Parkinson Association.PARTICIPANTS:
Patients (N=30) with PD (modified Hoehn & Yahr stages 2-3) were randomly divided into 2 groups a progressive RT group (PD training [PDT] group) and a control group (PD control [PDC] group). In addition, a group of paired healthy control (HC) subjects without PD was evaluated.INTERVENTIONS:
The PDT group performed 5 resistance exercises, 2 to 4 sets, 12 to 6 repetitions maximum per set. Individuals in the PDC group maintained their usual lifestyle. MAIN OUTCOMEMEASURES:
The PDT and PDC groups were evaluated before and after 12 weeks. The HC group was evaluated once. Autonomic function was assessed by spectral analysis of heart rate variability and cardiovascular responses to autonomic stress tests (deep breathing, Valsalva maneuver, orthostatic stress).RESULTS:
Compared with baseline, the normalized low-frequency component of heart rate variability decreased significantly after 12 weeks in the PDT group only (PDT 61±17 normalized units [nu] vs 47±20nu; PDC 60±14nu vs 63±10nu; interaction P<.05). A similar result was observed for systolic blood pressure fall during orthostatic stress that also was reduced only in the PDT group (PDT -14±11mmHg vs -6±10mmHg; PDC -12±10mmHg vs -11±10mmHg; interaction P<.05). In addition, after 12 weeks, these parameters in the PDT group achieved values similar to those in the HC group.CONCLUSIONS:
In patients with PD, progressive RT improved cardiovascular autonomic dysfunction.Palavras-chave
