Utilizing Perceived Exertion to Guide Exercise Intensity in Home-Based Cancer Rehab

Overview

This study analyzed 3533 exercise sessions from 76 cancer survivors participating in a six-month home-based digital exercise program. It demonstrated that subjective ratings of perceived exertion (RPE) effectively corresponded with heart rate-based intensity, supporting RPE as a practical tool to guide exercise intensity in unsupervised cancer rehabilitation.

Background

Exercise is a vital component of cancer survivorship care, improving quality of life and reducing treatment-related side effects. Home-based exercise programs supported by digital tools offer flexible, accessible rehabilitation but face challenges in maintaining appropriate exercise intensity without supervision. Heart rate monitoring is commonly used but requires equipment and testing, limiting scalability. The Borg CR10 scale for RPE is a low-cost alternative that has shown validity in cardiac rehabilitation but requires validation in home-based cancer exercise settings.

Data Highlights

Key Findings

• RPE ratings closely aligned with heart rate-based exercise intensity during unsupervised home-based sessions.
• Participants were able to self-regulate exercise intensity within the recommended moderate-to-vigorous range using RPE guidance.
• Use of the Borg CR10 scale enabled flexible pacing and intensity adjustments without the need for heart rate monitoring equipment.
• Discrepancies between RPE and heart rate intensity were influenced by individual factors but were generally minimal.
• The digital exercise program was feasible, safe, and well accepted by cancer survivors post-curative treatment.

Clinical Implications

Clinicians can consider incorporating RPE-based guidance using the Borg CR10 scale in home-based cancer rehabilitation programs to effectively monitor and direct exercise intensity without reliance on heart rate monitors. This approach may enhance scalability and patient adherence by simplifying intensity regulation in unsupervised settings. Educating patients on using RPE can empower self-management and maintain safety during exercise.

Conclusion

Subjective perceived exertion is a valid and practical method to guide and assess exercise intensity in home-based cancer rehabilitation, facilitating effective and safe unsupervised training. Integrating RPE into digital exercise interventions may improve accessibility and adherence among cancer survivors.
