Exercise reduces C-reactive protein and improves physical function in automotive workers with low back pain.

INTRODUCTION

Little is known about the effect of exercise on C-reactive protein (CRP) in patients with low back pain (LBP). The aim of the study was to investigate the effects of 8-week exercise intervention on CRP and physical function in automotive workers with LBP.

METHODS

Thirteen male workers (40 +/- 6 years) with LBP completed an 8-week multicomponent exercise intervention program which consisted of resistance training, swimming, stretching and hiking. Serum CRP concentration and physical functions were measured at baseline and after 8-week exercise intervention.

RESULTS

Compared to baseline, CRP levels decreased by 38% (P = 0.005), back flexibility improved, isokinetic leg strengths increased (all P < 0.05), and back strength tended to increase.

CONCLUSIONS

The results of the present study show that CRP levels decrease with exercise in subjects with LBP and physical function improves. This suggests that exercise-related decreases in inflammation in persons with LBP are associated with improvements in physical function.
