Effects of physical exercise on serum levels of serotonin and its metabolite in fibromyalgia: a randomized pilot study.

By Valéria Valim, et al.

Abstract:

To evaluate the effects of aerobic training and stretching on serum levels of serotonin (5HT) and its main metabolite 5-hydroxindolacetic acid (5HIAA).

Twenty-two women with FM were randomized into one of two exercise modalities (aerobic walking exercise or stretching exercise) to be accomplished three times a week for 20 weeks. The serum levels of 5HT and 5HIAA were evaluated before and after the exercise program by high performance liquid chromatography (HPLC) with colorimetric detection.

  • Within group analysis (pre-post) showed that serum levels of both 5HT and 5HIAA changed significantly in the aerobic group during the 20-week course of therapy (5HT: P = 0,03; 5HIAA: P = 0,003).

  • In the stretching group, however, no statistically significant change was observed (5HT: P=0,491; 5HIAA: P=0,549).

  • Between group statistical comparisons of laboratory measures disclosed that aerobic training was superior to stretching in that it significantly increased the levels of 5HIAA (F test = 6.61; P = 0.01), but the average difference between groups on the levels of 5HT did not meet significance criteria (F test = 3.42; P = 0.08).

Aerobic training increases the 5HIAA and 5HT levels and it could explain why aerobic exercise can improve symptoms in fibromyalgia syndrome patient more than stretching exercise.
