Key Findings
- 01High test-retest reliability for ISST bilaterally (Right: r = 0.89; Left: r = 0.79, p <0.05).
- 02Standard Error of Measurement (SEM) (%) ranged from 9.09% to 12.47%.
- 03Minimal Detectable Change (MDC) for Peak Force (PF) was 25.19 – 34.56 N.
- 04No significant difference was detected between bilateral test values.
Application
Design takeaway
Implement the standardized ISST protocol to reliably assess and monitor soleus strength in athletes, enabling informed decisions regarding training load and injury prevention.
How to apply
When designing or selecting strength assessment tools for athletes, prioritize those with established test-retest reliability. Ensure a clear, standardized protocol is developed and followed for all measurements.
Project actions
- 01When designing a test, consider how you will ensure it can be repeated with similar results.
- 02Think about the specific muscle groups or movements relevant to your design project and how you might measure their performance.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Focus on an elite population where precise monitoring is critical.
- +Clear methodology with statistical analysis for reliability.
Limitations
Consider if your chosen testing method is practical for your target user group and context. Are there environmental factors that could affect results? Is the test too time-consuming or complex?
Reliability & validity
The study focuses on test-retest reliability, indicating that the ISST provides consistent measurements over time when administered under the same conditions. Validity (whether the test measures what it intends to measure, i.e., soleus strength) is assumed based on the muscle group targeted and the nature of the isometric contraction, but not directly tested in this study.
Think critically
How might the 'minimal detectable change' (MDC) influence the interpretation of results for an athlete who shows a change in strength just below this threshold?
Design Principles
"Consistent and repeatable measurement protocols are fundamental for accurate physiological assessment and performance tracking."
Reliable measurement tools are crucial for effective performance monitoring and injury risk assessment in sports. The ISST's demonstrated reliability allows practitioners to confidently track changes in soleus strength over time, informing training adjustments and readiness to play decisions.
What This Means for Your Design
This study shows that a specific test for calf muscle strength (the ISST) gives consistent results when the same elite football players do it twice, with a 2-day break in between. This means it's a good, reliable test to use for tracking athlete fitness.
How to use in your project
- 1.Reference this study when discussing the importance of reliable measurement tools in your design project's evaluation phase.
- 2.Use the findings to justify the selection of specific testing methods for your own user research or performance analysis.

Paragraph starter
The reliability of measurement tools is paramount in design research, as it ensures that observed changes or performance metrics are attributable to the intervention or design, rather than random error. Studies such as Rhodes et al. (2022) on the Isometric Soleus Strength Test (ISST) demonstrate that standardized protocols can yield high test-retest reliability (r = 0.89 for the right leg), providing a dependable basis for monitoring athlete performance and informing training strategies. This highlights the importance of establishing robust and repeatable testing procedures within any design project that involves quantitative user assessment.
