Neck extensor endurance can be relevant in sport, gym training, contact sports, cycling, desk work, overhead tasks and activities that require sustained head position. The Neck Extension Endurance Test provides a practical way to assess how long or how many repetitions a client can maintain controlled neck extension.
The test can be performed as a prone hold, prone repetition test or resisted extension endurance assessment.
The result should not be used alone to diagnose neck pain, determine injury risk or make return-to-sport decisions. It should be interpreted with symptoms, cervical ROM, neck flexion endurance, lateral flexion endurance, isometric strength, posture, sport or work demands and related shoulder or upper-limb findings.
Test name: Neck Extension Endurance Test
Common versions: Prone neck extension hold, prone extension repetition test, resisted extension endurance test
Category: Cervical extensor strength endurance
Primary score: Hold time in seconds or valid repetitions completed
Best use: Baseline testing, retesting and monitoring posterior neck endurance
Key limitation: Protocol variation strongly affects scores, and results should not be interpreted as isolated extensor muscle capacity
The Neck Extension Endurance Test assesses the client’s ability to hold or repeatedly perform controlled cervical extension.
Common approaches include:
Prone neck extension hold
Prone neck extension repetitions
Neck extensor endurance with head supported then lifted
Seated resisted neck extension hold
Isometric neck extension endurance against a pad or fixed resistance
Other standardised extension endurance setups
The exact setup must be recorded because head position, torso support, gravity demand, ROM, tempo and stopping criteria all change what the test measures.
The Neck Extension Endurance Test may be used to assess posterior neck endurance, cervical extensor fatigue tolerance, baseline and retest change, response to neck endurance training, symptom response during extension-based loading, postural endurance context and cervical control during sport, gym or work tasks.
It may also provide useful context when combined with neck flexion endurance, lateral flexion endurance, cervical ROM, isometric neck strength and symptom monitoring.
The primary score is valid hold time in seconds or valid repetitions completed, depending on the chosen protocol.
The result may reflect cervical extensor endurance, posterior neck control, upper and lower cervical position control, fatigue tolerance, trunk and shoulder support influence, pain or symptoms, familiarisation and motivation.
It should not be described as isolated endurance of one specific posterior neck muscle.
The test may be useful for contact sport athletes, combat sport athletes, cyclists, swimmers, desk-based workers, manual workers, gym and strength-training clients, clients undergoing neck endurance monitoring and professionals tracking changes over time.
It may not be suitable if the client has acute trauma, high irritability, dizziness, neurological symptoms, severe pain, recent surgery, poor tolerance to prone positioning or inability to maintain safe head control.
Mat, table or bench
Stopwatch or Measurz stopwatch
Measurz rep counter for repetition-based testing
Measurz metronome for cadence-controlled protocols
Optional towel or support pad
Optional Measurz AR measurement or inclinometer for head position or ROM consistency
Optional MAT tools such as Anker or Muscle Meter for related isometric neck extension strength testing
Measurz platform for hold time, reps, symptoms, compensations and retest comparison
For timed holds, use the Measurz stopwatch. For repetition-based testing, the Measurz rep counter and metronome can help standardise counting and tempo.
The client lies prone with the head and neck positioned according to the chosen protocol.
The trunk is supported and relaxed.
The client lifts or holds the head in the target extension or neutral position.
Start timing once the correct position is achieved.
The client maintains the position without excessive upper-back extension, shoulder tension or head rotation.
Stop when head position drops, symptoms become unacceptable, compensation occurs or the client chooses to stop.
Record hold time and reason for stopping.
The client lies prone in the selected start position.
The client performs controlled neck extension repetitions through the selected ROM.
Use a consistent tempo if comparing over time.
Count valid repetitions until form failure, cadence failure, symptom increase, compensation or voluntary stop.
Record repetitions, tempo and reason for stopping.
The client sits upright with the trunk stable.
A pad, hand, strap or fixed resistance is positioned behind the head.
The client gently pushes into extension against the resistance.
Start timing once the target effort or position is reached.
Stop when position, effort, symptoms or form criteria are no longer maintained.
Record time, resistance method and reason for stopping.
Record the version, hold time or repetitions completed, body position, head and neck start position, target position, ROM, tempo or cadence, pain or symptoms, compensations, reason for stopping and retest date.
A higher score generally suggests greater neck extension endurance under the chosen protocol, but interpretation should consider setup, symptom response, fatigue, motivation and test familiarity.
The most useful comparison is usually the client’s own baseline using the same protocol.
Published research has examined cervical extensor endurance testing, but broad universal norms should still be used cautiously because protocols and populations vary.
As practical field-use bands only, and only when the same protocol is used:
For hold-based testing:
Strong current tolerance: 60+ seconds
Moderate current tolerance: 30–59 seconds
Developing current tolerance: 15–29 seconds
Low current tolerance: under 15 seconds
For repetition-based testing:
Strong current endurance: 20+ valid repetitions
Moderate current endurance: 10–19 repetitions
Developing current endurance: 5–9 repetitions
Low current endurance: under 5 repetitions
These values are practical benchmarks, not universal norms. For stronger evidence-backed benchmarking, use exact-protocol studies, internal Measurz group data, symptom response, baseline comparison and retesting.
Cervical extensor endurance testing has published reliability research, and recent studies have explored normative values. However, reliability and interpretation remain protocol-specific.
Reliability depends on consistent body position, head position, gravity demand, target angle, resistance method, stopping criteria, verbal instructions and retesting conditions.
Validity should be interpreted cautiously. The test may provide useful cervical extensor endurance information, but it should not be used alone to diagnose neck pain, identify a specific tissue source or determine injury risk.
Common errors include changing body position, changing head start position, allowing head rotation, allowing excessive upper-back extension, using inconsistent ROM, counting poor-quality repetitions, using inconsistent tempo, failing to record symptoms, continuing after form failure, comparing different protocols and using one score to infer injury risk or readiness.
Limitations include protocol variability, symptom irritability, fatigue, familiarisation, motivation and contribution from trunk and shoulder positioning.
The Neck Extension Endurance Test can help professionals monitor posterior neck endurance, track response to neck endurance training, record fatigue tolerance, document symptom response, compare flexion and extension endurance, combine findings with cervical ROM and isometric neck strength, and educate clients using a simple repeatable endurance measure.
Record test name, version, score type, body position, head and neck start position, target position, ROM, tempo or cadence, pain score, symptoms, compensation notes, reason for stopping, retest date and related strength, ROM and endurance results.
The Measurz stopwatch, rep counter and metronome can support consistent testing. AR measurement and inclinometer tools can help document setup or position if needed. MAT tools such as Anker or Muscle Meter can provide related isometric neck extension strength measures when appropriate.
It measures cervical extensor endurance and the ability to maintain controlled posterior neck position under the chosen protocol.
No. It can involve several posterior neck muscles and may be influenced by trunk, shoulder and head-position control.
Published values vary by protocol and population. Use baseline comparison, exact-protocol comparison and repeat testing with the same setup.
Yes. Record pain, tightness, dizziness, headache, fatigue, compensation and reason for stopping.
It can provide useful endurance information, but it should be interpreted with symptoms, ROM, strength, posture and functional findings.
The Neck Extension Endurance Test is best described as a cervical extensor endurance assessment.
Published evidence is protocol-specific, so setup consistency is essential.
The test should not be described as isolated posterior neck muscle endurance.
Setup details such as body position, head position, ROM and stopping criteria are essential.
Measurz can track reps, time, symptoms, compensations, setup and retest progress.
