Combined strength, flexibility and aerobic exercise program for chronic low back pain

Official title: A Combined Exercise Programme Involving Strengthening, Flexibility and Aerobic Exercise for Lower Back Pain: a Randomised-controlled Study

Run by University of Nottingham · NCT06921694 · Data updated 2026-11-12

This program will test whether an 8-week combined exercise plan—running or swimming/cycling plus progressive strength and flexibility work—helps adults aged 18–45 with chronic low back pain reduce pain and improve function compared with their usual exercise.

Is this trial a fit for you?

Likely a good fit

Adults aged 18–45 with chronic non-specific low back pain for more than three months who have at least moderate pain or functional limitation and are able and willing to exercise are ideal candidates.

Probably not a fit

People with radiating leg pain or sciatica, specific spinal diagnoses (e.g., herniated disc, spinal stenosis), prior spinal surgery, major comorbid bone or joint disease, pregnancy, or those unable to undertake exercise are unlikely to benefit from this program.

What this trial studies

This randomized, three-arm trial will allocate community-recruited adults with chronic non-specific low back pain to usual exercise (control), a running-based intervention, or a swimming/cycling-based intervention. The two active arms complete an 8-week progressive program that combines aerobic training (running or swim/cycle), resistance training, and prescribed flexibility exercises. Patient-reported outcome measures for pain and function are collected at baseline, 8 weeks (post-intervention), and 12 months to capture short-term and longer-term effects. The interventions are structured to increase intensity gradually to support adherence and reduce injury risk.

Why it matters

Potential benefit: If successful, the program could reduce pain and improve physical function in people with chronic non-specific low back pain, with benefits that may last up to 12 months.

How similar studies have gone: Exercise-based treatments have substantial evidence of benefit for chronic low back pain overall, but direct randomized comparisons of running versus swimming/cycling combined with structured resistance and flexibility programs are limited.
