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 OUTCOME MEASURES: 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.
