Effects of two training programs on health variables in adults with chronic low back pain: a randomized clinical trial.

Abstract

Aim: To analyze the effects of two training programs on health variables in adults with low back pain (LBP). Methods: Thirty-eight adults were randomly divided into three groups: resistance training (RG); resistance training with core training (RCG) and control (CG). Results: There were reductions in body mass index (BMI) in RG and RCG, waist circumference in RG and RCG, pain in RG, RCG and CG, CK in RCG, stress in RG and RCG, functional deficiency in RG and RCGand increases in trunk flexor and extensor strength in the RG and RCG. Conclusion: Resistance training, with or without core training exercises, reduced the levels of LBP, functional disability, stressand CK, and increased the strength of trunk flexors and extensors. Trial registration: Brazilian Clinical Trials Registry: ReBEC (RBR-5khzxz).
