Key Findings
- 01Seven out of 24 anthropometric features showed small differences between left and right sides in elite female fencers.
- 02Morphological asymmetry indices did not exceed 5%.
- 03Left-sided lateralization was associated with significantly higher asymmetry, particularly larger minimum forearm circumferences in the right limb.
Application
Design takeaway
Designers and coaches should recognize that even small physical asymmetries can have functional consequences, necessitating individualized approaches to training, equipment design, and injury management.
How to apply
When designing sports equipment or training programs, consider incorporating assessments for limb length and circumference differences to inform customization and injury prevention strategies.
Project actions

Variables
Strengths & Limitations
Strengths
- +Focus on elite athletes provides insights into high-level performance implications.
- +Combines both morphological and functional assessments for a more comprehensive view.
Limitations
It can be challenging to recruit a large enough sample of elite athletes. Measuring subtle functional differences accurately can also be difficult without specialized equipment.
Reliability & validity
Reliability would depend on the consistency of anthropometric measurements and the objective scoring of functional assessments. Validity would be strengthened by correlating asymmetry measures with actual performance data or injury records.
Think critically
How might the specific demands of fencing, such as the dominant lunging side, contribute to or exacerbate these observed morphological and functional asymmetries?
Design Principles
"Design for individual biomechanical variations, especially in highly specialized activities."
Understanding and monitoring subtle physical asymmetries in athletes is crucial for optimizing training regimens and developing targeted injury prevention and rehabilitation strategies. This research highlights the importance of a holistic approach that considers both the physical structure and the functional capabilities of an athlete's body.
What This Means for Your Design
Even tiny differences in how your left and right arms or legs are shaped can affect how well you perform in sports like fencing and might make you more likely to get hurt. It's important to know about these differences to train smarter and stay safe.

This research highlights the critical link between subtle morphological asymmetries and functional performance in athletes. For instance, Bany et al. (2025) found that even minor differences in limb circumference and length among elite fencers were associated with functional lateralization, impacting performance and injury risk. This underscores the need for designers to consider individual biomechanical variations when developing sports equipment or training methodologies, moving beyond generalized anthropometric data to account for nuanced physical differences that can influence user outcomes.
