# Single-Leg Adductor Plank Test

This is a higher-demand adductor and lateral trunk endurance test requiring clear setup and failure criteria.

The Single-Leg Adductor Plank is a Copenhagen-style adductor endurance assessment. Exact endurance norms are limited, but related research supports Copenhagen adduction testing and newer work has investigated test-retest reliability for measuring eccentric hip adductor strength during the Copenhagen adduction exercise.

## Introduction

The test challenges adductor capacity, lateral trunk endurance and shoulder support. It should be interpreted as an integrated adductor/trunk endurance task.

## Quick Summary

**Test name:** Single-Leg Adductor Plank  
**Category:** Hip adductor and lateral trunk endurance  
**Primary scores:** Hold time or repetitions  
**Best use:** Side-to-side adductor endurance comparison  
**Key limitation:** Exact endurance norms are limited.

## What Is the Assessment?

The client performs a Copenhagen-style plank with the top leg supported on a bench or box.

## Why It Is Used

Used to monitor adductor endurance, side-to-side differences, trunk control and progress over time.

## What It Measures

It may reflect hip adductor endurance, lateral trunk control, shoulder support and pelvic stability.

## Who It Is Used For

Useful for field sport athletes, court sport athletes, runners and clients requiring adductor capacity monitoring.

## Equipment Required

-   Bench or box
    
-   Mat
    
-   Stopwatch or **Measurz stopwatch**
    
-   **Measurz rep counter**
    
-   **Measurz metronome**
    
-   Optional **Measurz AR measurement** for bench height
    
-   MAT tools for related hip adductor isometric strength testing
    

## Step-by-Step Protocol

1.  Client sets up in a side plank with top leg supported on a bench.
    
2.  Bottom leg position depends on version.
    
3.  Client holds trunk and pelvis alignment.
    
4.  Record hold time or reps.
    
5.  Stop for hip drop, trunk rotation, symptoms or voluntary stop.
    

## Scoring and Interpretation

Record side, time/reps, bench height, version, symptoms and compensations.

## Normative Data, Benchmarks or Reference Values

Formal endurance norms are limited.

**Practical field guide only:**

-   Strong: 45+ seconds or 20+ controlled reps
    
-   Moderate: 20–44 seconds or 10–19 reps
    
-   Developing: under 20 seconds or under 10 reps
    

## Reliability and Validity

Related Copenhagen adduction research supports reliable measurement of adductor strength during Copenhagen-style tasks, but endurance-hold norms remain limited.

## Common Errors and Limitations

Hip drop, trunk rotation, shoulder collapse, inconsistent bench height, not recording symptoms and comparing modified/full versions directly.

## Practical Applications

Useful for adductor endurance monitoring, side-to-side comparison and field sport capacity profiling.

## How to Record This in Measurz/MAT

Record side, time/reps, bench height, version, pain, symptoms, compensations and retest date. Use stopwatch, rep counter, metronome and AR measurement where relevant.

## FAQs

**Is this the same as a Copenhagen plank?** It is a Copenhagen-style variation.  
**Are there norms?** Exact endurance norms are limited.  
**Should both sides be tested?** Yes.  
**Can it diagnose groin pain?** No.

## Key Takeaways

-   Integrated adductor and trunk endurance test.
    
-   Exact norms are limited.
    
-   Use side-to-side comparison.
    
-   Record bench height and version.
    
-   Measurz can track time, reps and symptoms.
