Endurance capacity was determined by bicycle spiroergometry in patients with panic
disorder before (n = 38) and after (n = 10) a 10 week running program and compared
to untrained healthy control subjects carrying out the same training (n = 11) and
patients receiving clomipramine drug therapy (n = 7) or placebo (n = 7). Before the
running program maximal oxygen uptake (VO2peak) and the workload corresponding to a lactate concentration of 4 mmol/l (PLAC4) were significantly reduced in panic patients compared to controls. Patients in the
running program and healthy controls improved PLAC4 significantly by running. No significant
differences in endurance gains were found between these groups, showing that patients
and controls improved equally. At study termination (week 10) running was more efficient
than placebo in improving panic symptoms (Bandelow Panic Agoraphobia Scale, Hamilton
Anxiety Scale, Clinical Global Impression Scale). Clomipramine treatment was better
than placebo (all scales) and running (only Clinical Global Impression). Endurance
capacity did not correlate with anxiety scores at baseline, nor did improvement in
fitness substantially correlate with changes in psychopathology measures during the
study. Panic patients were shown to have a decreased endurance capacity which can
be raised by training. Endurance training based on spiroergometric results gives rise
to clinical improvement.
