Borg Scale CR-10 Intensity Dosing Safely Enhances Physical Fitness in Central Core Myopathy Patients

Frontiers in Physiology · 2024

Key Findings

01The tailored training program led to significant improvements in maximal aerobic capacity (+15%).
02Body composition improved with an increase in muscle mass (+1.1 kg) and a decrease in fat mass (-1.1 kg).
03These positive changes occurred without reported pain, rhabdomyolysis, or elevated serum CK levels compared to pre-training values.

Application

Design takeaway

How to apply

When developing fitness or rehabilitation programs for individuals with known physiological sensitivities or risks, use subjective scales for perceived exertion and establish baseline physiological markers to monitor during the program.

Project actions

01Consider using subjective scales like the Borg scale to gauge user effort in your design project.
02If your project involves physical activity or physiological responses, explore how to incorporate relevant biomarker monitoring.

Method & Evidence

AimTo investigate if a tailored physical training program, guided by Borg CR-10 scale intensity and creatine kinase monitoring, can safely improve physical fitness and body composition in a patient with central core myopathy.

MethodCase study with pre- and post-intervention testing.

ProcedureA 17-year-old male with central core myopathy underwent a preliminary tolerance test using the Borg CR-10 scale (level 6 intensity) for aerobic, resistance, and mixed exercises, with serum creatine kinase (CK) measured 36 hours post-session. Based on these results, a 3-month mixed aerobic/resistance training program with a personalized nutritional plan was implemented. Metabolic and cardiopulmonary tests were conducted before and after the intervention.

Sample1 participant

ContextClinical exercise physiology and rehabilitation for rare neuromuscular disorders.

Variables

IVTailored physical training program (intensity, duration, type, nutritional plan).

DVMaximal aerobic capacity, body composition (muscle mass, fat mass), serum creatine kinase levels, reported pain.

CVParticipant's diagnosis (central core myopathy), age, gender (implied male).

Strengths & Limitations

Strengths

+Demonstrates a novel approach to exercise prescription for a rare condition.
+Successfully achieved positive outcomes without adverse effects.

Limitations

The findings are based on a single individual, so it's difficult to say if this approach would work for everyone with central core myopathy.

Reliability & validity

The study's validity is limited by its single-case design. Reliability of the Borg scale is generally considered good for subjective reporting, but the physiological measurements would need standardized protocols for replication.

Think critically

What are the potential ethical implications of using creatine kinase monitoring in a broader, non-clinical design context, and how could alternative, less invasive biomarkers be explored?

Design Principles

"Personalize exercise intensity and progression based on a combination of subjective exertion feedback and objective physiological response monitoring."

This research provides a practical framework for designing exercise interventions for individuals with specific physiological limitations. By linking subjective exertion levels to objective physiological markers, designers can create safer and more effective programs that mitigate risks like rhabdomyolysis and myalgia.

What This Means for Your Design

This study shows that by asking someone how hard they feel they are working (using a scale) and checking their blood for muscle damage markers, you can create a safe and effective exercise plan for people with certain muscle conditions.

How to use in your project

1.Reference this study when discussing the importance of user-specific physiological responses and the use of subjective feedback in tailoring design solutions.
2.Use it to justify the inclusion of user testing methods that measure both perceived effort and physiological outcomes.
