Chronic effects of aerobic exercise on panic disorder: a systematic review of randomized and non-randomized trials

BACKGROUND: In general, most studies have supported an association between the acute effects of exercise and a reduced state anxiety, but failed to completely explain the relationship between the chronic effect of exercise and anxiety traits. OBJECTIVE: The aim of this study was to systematically review the literature regarding the chronic effect of exercise on symptoms associated with panic disorder. METHODS: The studies were retrieved from a MEDLINE/PubMed, ISI Web of Knowledge and SciELO. We adopted PICOS’s strategy recommended to determine the eligibility criteria. The survey was conducted using an advanced search in the ISI Web of Science and MEDLINE / PubMed with MeSH terms and Entry Terms for the keywords “Panic Disorder” basis and “Exercise”. Boolean operators “AND” and “OR” were used separately or in combination. Two independent researchers performed the selection of studies; in case of disagreement they sought a consensus on the selection. RESULTS: A total of 265 articles were identified: 199 articles from PubMed/Medline, 63 articles from ISI Web of Science and 3 articles by manual searches. Thus, 31 articles were analyzed by the eligibility criteria and the exclusion criteria, a total of five studies included in the systematic review. CONCLUSION: The regular practice of aerobic exercise seems to be an appropriate intervention to promote improvements in the severity of anxiety symptoms in PD patients.
