Key Findings
- 01Five distinct latent profiles were identified based on spinal deep muscle strength.
- 02Profiles with higher body weight and skeletal muscle mass (G2 and G4) demonstrated superior grip, back, and leg strength.
- 03No significant correlation was found between spinal muscle strength and balance.
Application
Design takeaway
Designers of athletic training equipment and performance analysis systems should consider the varied relationships between core strength and other physical attributes, moving beyond simple correlations to support individualized athlete development.
How to apply
When designing training regimens or equipment for combat sports, consider assessing and profiling core strength alongside other key performance indicators like balance and explosive power, rather than assuming a direct correlation.
Project actions
- 01When studying athlete performance, consider using profiling techniques like latent profile analysis to identify subgroups.
- 02Ensure your research design allows for the investigation of non-linear or non-correlated relationships between different physical attributes.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Utilized latent profile analysis to identify distinct athlete subgroups.
- +Investigated a comprehensive range of physical fitness and body composition measures.
Limitations
The study was conducted in a lab, which might not reflect real-world training conditions. The findings are specific to adolescent Taekwondo athletes and may not apply to other sports or age groups.
Reliability & validity
The use of a standardized measurement machine (Centaur 3D) and established physical fitness tests likely contributes to reliability. The latent profile analysis provides a statistical method for identifying distinct groups, enhancing construct validity by capturing complex relationships.
Think critically
Given that core strength and balance did not correlate in this study, how might this influence the design of training equipment or methodologies for sports where both are critical?
Design Principles
"Performance optimization requires understanding and catering to heterogeneous physiological profiles within athlete populations."
Understanding these diverse profiles allows for more targeted training programs. Designers of athletic equipment and training methodologies can leverage this insight to develop tools and strategies that address specific performance gaps identified within these athlete subgroups.
What This Means for Your Design
Different groups of Taekwondo athletes have different types of core strength and fitness, and sometimes having strong core muscles doesn't automatically mean you're good at everything, like balancing.
How to use in your project
- 1.This study can inform the design of a performance assessment tool for athletes, highlighting the need to measure multiple, potentially uncorrelated, physical attributes.
- 2.The findings can justify the development of a training program that targets specific weaknesses identified in different athlete profiles.

Paragraph starter
This research highlights that within elite Taekwondo athletes, distinct profiles of spinal deep muscle strength and physical fitness exist, suggesting that a one-size-fits-all approach to training and performance assessment may be suboptimal. The identification of specific athlete groups, some with high core strength but no corresponding improvement in balance, underscores the need for nuanced design considerations in athletic development tools and programs.
