OBJECTIVES: The anxiolytic effect of regular aerobic exercise in panic disorder patients is well known. However, a protocol for aerobic exercise intervention as an adjunct non-pharmacologic treatment for panic disorder is still lacking. Our aim was to propose and present a pilot study about an aerobic training protocol that could be replicable, safe and viable for other clinical trials with panic disorder patients.
METHODS: A total of 24 exercise sessions (twice/week) of treadmill walking at controlled intensity (75% VO2max) were completed by four panic disorder patients.
RESULTS: No major complications were observed. The benefits of the aerobic training intervention were reflected in favorable changes in the Panic and Agoraphobia Scale, the Cardiac Anxiety Questionnaire, the Anxiety Sensitivity Index and in the Body Sensations Questionnaire scores, in spite of no significant differences in physiological variables.
CONCLUSIONS: The proposed protocol of aerobic training intervention was shown to be a safe and potentially useful tool as adjunct non-pharmacologic treatment of panic disorder. Further studies are needed in order to determine whether higher intensities and/or longer exercise interventions would induce physiological benefits while still being feasible and safe.

BACKGROUND: Cardiac vagal index (CVI) is supposedly higher in athletes and may differ between sports and/or between field positions.
OBJECTIVE: To compare CVI: a) between elite football players vs. non-athletes and b) according to five football positions.
METHOD: 242 football players of the first Brazilian/Angolan division were divided in five positions (N): goalkeepers (17), defenders (44), wingers (34), midfielders (87) and forwarders (60) and compared with 303 age-matched healthy non-athletes. CVI was estimated from a 4-second exercise test by quantifying the ratio of two cardiac cycle durations, before and at the end of a fast unloaded cycling exercise.
RESULTS: Football players had resting and maximal heart rates of, respectively, 59 and 190 bpm and measured VO2max of 62.2 mL/(kg.min). Players and non-athletes showed similar CVI results (median-[P25-P75]) – 1.63- [1.46-1.84] vs 1.61-[1.41-1.81] (p = 0.22). Wingers tended to have a higher CVI (1.84-[1.60-1.99]), especially when compared to defenders (1.53-[1.41-1.72] (p = 0.01). There was a modest non-physiologically relevant association between VO2max and CVI (r = 0.15).
CONCLUSIONS: Football players did not differ from non-athletes in CVI; however, among players, wingers were more often vagotonic, which may represent a hemodynamic advantage for match situations, where rapid heart rate transitions and faster oxygen delivery to muscles are required.

BACKGROUND: There is limited evidence regarding the use of exercise training in the treatment of panic disorder.
OBJECTIVE: To describe the role of psychological and cardiorespiratory variables in the therapeutic effect of a 12-week exercise training in panic disorder patients.
METHODS: Eleven symptomatic panic disorder patients completed 24 sessions, 2 sessions/week, 70%VO2max) aerobic exercise training in addition to regular pharmacological treatment. Assessment was performed at baseline, six and 12-week periods. Exercise training intensity was individualized according to maximal cardiopulmonary exercise testing data.
RESULTS: Patients who exercised in conjunction with pharmacotherapy obtained significant improvements in several variables. Exercise training produced a selective, rather than a general anxiolytic impact. An early (6-week) effect was observed in fear of physiological arousal, interoceptive conditioning and in the frequency and intensity of panic attacks. Smaller additional 12-week effects were found in health concerns and agoraphobic cognitions, with no significant impact in agoraphobia.
CONCLUSION: A 12-week aerobic exercise training protocol was well-tolerated and able to improve several psychological and cardiovascular indicators in most patients with panic disorders. Further studies are needed to identify the best training protocols and long-term effects of exercise, as well as interactions between cardiorespiratory and psychological variables in this context.
