NordBord Test Protocols

When using the NordBord, you can select from several pre-programmed hamstring tests. 

These tests and related protocols are listed below: 

Nordic The Nordic test is the most common NordBord test, and the best supported by research.

Contraction Mode:  Eccentric
Rep Detection: Bilateral (i.e. both legs must contract simultaneously to register a rep during a test)

Starting Position:  
Ankle hooks placed around the tops of the ankles.
Kneeling on the NordBord.
Head up and chest tall.

Instructions for the Individual:
Keep their body straight.
Begin to lean forward, then resist falling. 
Catch themself on the ground.
Assume starting position again.
Repeat for the required number of reps.


Razor The Razor is a common alternative to the Nordic test, this test features extension of both the hip and knee during the movement.

Contraction mode: Eccentric
Rep Detection: Bilateral (i.e. both legs must contract simultaneously to register a rep during a test)

Starting Position:
Kneeling on the NordBord.
Ankle hooks placed around the tops of the ankles.
Head up and chest tall.

Instructions for the Individual:
Keep their torso straight.
Bend forward at their hips, then extend forwards and resist falling. 
Catch themself on the ground.
Assume starting position again.
Repeat for the required number of reps.

ISO Prone (0°) The ISO Prone test is an end-range isometric strength test.  

Contraction mode: Isometric
Rep Detection: Unilateral (i.e. legs can contract simultaneously or one at a time to register reps during a test)

Starting Position:
Ankle hooks placed around the tops of the ankles.
Kneeling on the NordBord with elbows on the ground.
Legs straight.

Instructions for the Individual:
Keep their legs straight.
Pull up on the hooks for the prescribed time.
Relax.
Repeat for the required number of reps.


ISO 30° The ISO 30° test is  the most common isometric NordBord test.  This long-length isometric strength test, is often used to roughly mimic the knee joint angle during the "strike" position in running gait. 

Contraction mode: Isometric
Rep Detection: Unilateral (i.e. legs can contract simultaneously or one at a time to register reps during a test)

Starting Position:
Ankle hooks placed around the tops of the ankles.
Kneeling on the NordBord with hands on the ground. 
Knees bent 30°.

Instructions for the Individual:
Keep their legs in the same position (knees bent 30°).
Pull up on the hooks for the prescribed time.
Relax.
Repeat for the required number of reps.


ISO 60° The ISO 60° test is a shorter-length isometric strength test. 

Contraction mode: Isometric
Rep Detection: Unilateral (i.e. legs can contract simultaneously or one at a time to register reps during a test)

Starting Position:
Ankle hooks placed around the tops of the ankles.
Kneeling on the NordBord with hands on the ground.
Knees bent 60°.

Instructions for the Individual:
Keep their legs in the same position (knees bent 60°).
Pull up on the hooks for the prescribed time.
Relax.
Repeat for the required number of reps.

Custom The Custom test option enables you to create your own custom test name, and perform your own protocol as desired.

Rep Detection: Unilateral (i.e. legs can contract simultaneously or one at a time to register reps during a test)
