Supervised heavy resistance training with weekly undulating periodization shows feasibility for reducing pain and disability in individuals with persistent non-specific low-back pain (LBP). This approach improved pain intensity, disability, self-efficacy, and strength over 16 weeks.
Area of Science:
- Exercise Science
- Rehabilitation Medicine
- Pain Management
Background:
- Persistent non-specific low-back pain (LBP) affects a significant portion of the adult population.
- Investigating feasible and effective interventions for chronic LBP is crucial for improving patient outcomes.
- Heavy resistance training with periodization offers a potential therapeutic avenue for LBP management.
Purpose of the Study:
- To assess the feasibility of a 16-week supervised heavy resistance training program using weekly undulating periodization for individuals with persistent non-specific LBP.
- To evaluate changes in pain intensity, pain-related disability, pain self-efficacy, and muscle strength.
- To explore participants' experiences and perceptions of the training program.
Main Methods:
- A mixed methods feasibility study involving 25 adults with persistent non-specific LBP.
- Participants engaged in a 16-week whole-body resistance training program (squat, bench press, deadlift, Pendlay row) twice weekly.
- Outcomes (pain, disability, self-efficacy, strength) were assessed at baseline, 8, and 16 weeks, supplemented by focus group interviews.
Main Results:
- Clinically meaningful reductions in pain intensity were observed at 8 and 16 weeks (mean difference 2.6 and 3.4, respectively).
- Significant improvements were noted in pain-related disability, pain self-efficacy, and muscle strength.
- Qualitative data highlighted the importance of supervision, training periodization, and reported benefits in daily functioning, sleep, and energy levels.
Conclusions:
- Periodized resistance training with weekly undulating periodization is a feasible intervention for individuals with persistent non-specific LBP.
- The study supports the need for a randomized clinical trial to further establish the efficacy of this training method.
- This approach may offer a promising strategy for managing chronic low-back pain.
