Shoulder external rotation endurance can be relevant for overhead sport, throwing, swimming, racquet sports, gym training and work tasks that require repeated or sustained shoulder control. Unlike repetition-based external rotation tests, the hold version assesses how long the client can maintain an external rotation position under a scaled load. This can provide useful information about fatigue tolerance, position control and symptom response. The 5% bodyweight load is generally more manageable than a 10% bodyweight repetition protocol, but it still needs to be matched to the client’s ability, symptoms and control. The result should be interpreted alongside shoulder ROM, external rotation strength, shoulder flexion endurance, overhead tasks, symptoms and training demands. ## Quick Summary Test name: Shoulder External Rotation – Hold 5% BW Category: Shoulder external rotation isometric endurance Load: 5% of body weight Primary score: Hold time in seconds Best use: Sustained external rotation tolerance, side-to-side comparison, baseline comparison and retesting Key limitation: It is position-specific and should not be interpreted as complete rotator cuff function ## What Is This Assessment? The Shoulder External Rotation – Hold 5% BW Test assesses how long a client can hold a standardised shoulder external rotation position using a load equal to 5% of body weight. The test may be performed using a dumbbell, cable, machine or other measurable load, provided the setup is standardised. Common positions include: Side-lying external rotation hold Standing cable external rotation hold at the side Seated external rotation hold External rotation hold at 90 degrees abduction if specifically selected Machine external rotation hold The exact setup must be recorded because arm position, elbow angle, cable height, body position, ROM, load type and compensation all change the result. ## Why It Is Used The test may be used to assess: Sustained shoulder external rotation endurance Rotator cuff-focused endurance capacity Side-to-side differences External rotation position tolerance Fatigue response under a scaled load Baseline and retest change Symptom response during sustained external rotation Technique and position control under fatigue It is most useful when the same load calculation, equipment, arm position, ROM, hold angle and stopping criteria are repeated over time. ## What It Measures The primary score is hold time in seconds. The result may reflect: Sustained shoulder external rotation endurance Infraspinatus and teres minor contribution Posterior shoulder endurance Scapular control Elbow position control ROM and position consistency Pain or symptom response Technique control under fatigue Motivation and familiarisation It should not be described as isolated rotator cuff endurance because trunk position, scapular position, elbow position, loading method and technique all influence the result. ## Who It Is Useful For The test may be useful for: Overhead athletes Throwing athletes Racquet sport athletes Swimmers Gym clients Field sport athletes Clients with repeated shoulder loading demands Professionals monitoring shoulder endurance over time Clients where sustained external rotation tolerance is relevant It may not be suitable for clients with high shoulder irritability, pain during external rotation, poor external rotation ROM, poor position control, inability to maintain elbow position, or symptoms that increase with sustained external rotation. ## Equipment Required Dumbbell, cable, machine or measurable load Scale or known body weight Calculator for 5% bodyweight load Measurz stopwatch Optional Measurz metronome if using periodic position checks Optional towel roll for elbow positioning Optional video for technique review Measurz platform for load, hold time, side, symptoms, compensation and retest comparison ## Step-by-Step Protocol 1. Record the client’s body weight. 2. Calculate 5% of body weight. 3. Select the closest practical load and record the exact load used. 4. Choose the test position: side-lying, standing, seated, cable, dumbbell or machine. 5. Record side tested, arm position, elbow angle, equipment type, ROM target and hold angle. 6. If using a towel roll or elbow support, record this setup. 7. Ask the client to move into the selected external rotation hold position. 8. Start timing once the correct position is achieved. 9. The client holds the position without trunk rotation, wrist extension, elbow drift, shoulder hiking or loss of ROM. 10. Stop when position is lost, technique changes, symptoms become unacceptable or the client chooses to stop. 11. Record hold time and reason for stopping. 12. Repeat on the opposite side after consistent rest if side-to-side comparison is required. ## Scoring and Interpretation Record: Body weight Calculated 5% load Actual load used Side tested Hold time Arm position Elbow angle ROM or hold target Equipment type Body position Pain or symptoms Technique changes Compensations Reason for stopping Retest date A longer hold time generally suggests greater sustained shoulder external rotation endurance under the 5% bodyweight protocol. However, interpretation should consider load rounding, arm position, elbow control, ROM, fatigue, symptoms and technique quality. The most useful comparison is usually the client’s own baseline using the same setup, or left versus right using the exact same protocol. ## Normative Data, Benchmarks or Reference Values There are no widely accepted universal norms for Shoulder External Rotation – Hold 5% BW across all populations. Use practical field bands only when the same protocol is repeated: 60+ seconds: strong current tolerance 30–59 seconds: moderate current tolerance 15–29 seconds: developing current tolerance Under 15 seconds: low current tolerance These are practical guide ranges only. Baseline comparison, side-to-side comparison, symptom response, retest consistency and sport or work demands are more useful than rigid cut-offs. ## Reliability and Validity Reliability depends on consistent load calculation, load rounding, body position, arm position, elbow angle, ROM target, equipment type, warm-up, instructions and stopping criteria. The 5% BW protocol provides a standardised way to scale sustained external rotation load to body size, but the result should still be interpreted as test-specific performance rather than a complete shoulder function measure. Validity should be interpreted cautiously. The test may help monitor shoulder external rotation endurance under load, but it should not be used alone to diagnose shoulder pathology, injury risk, throwing capacity or readiness. ## Common Errors and Limitations Common errors include: Incorrect bodyweight load calculation Not recording actual load used Changing equipment type Changing elbow position Changing arm position Using trunk rotation Extending the wrist Losing the target external rotation angle Shrugging the shoulder Ignoring symptoms Comparing 5% and 10% BW tests directly Limitations include load rounding, fatigue, motivation, symptom irritability and influence from trunk, scapular and elbow control. ## Practical Applications The Shoulder External Rotation – Hold 5% BW Test can help professionals: Monitor sustained external rotation endurance Compare left and right sides Track fatigue response under load Record symptom response Identify compensation during sustained external rotation Guide endurance-focused shoulder programming Compare hold endurance with repetition-based external rotation results It is most useful when interpreted alongside shoulder ROM, shoulder external rotation strength, shoulder flexion endurance, shoulder flexion holds, push-up testing, overhead symptoms and sport or work demands. ## How to Record This in Measurz / MAT Record: Test name Body weight Calculated 5% load Actual load used Side tested Hold time Arm position Elbow angle ROM or hold target Equipment type Body position Pain score Symptom location Technique changes Compensation Reason for stopping Retest date Use the Measurz stopwatch for hold time. Use AR measurement or the inclinometer to help document ROM, arm position or setup where useful. ## FAQs ### What does Shoulder External Rotation – Hold 5% BW measure? It measures sustained shoulder external rotation endurance using a load equal to 5% of body weight. ### Is it an isolated rotator cuff test? No. It may involve the external rotators, but trunk position, scapular control, elbow position and technique also influence the result. ### How is the load calculated? Multiply body weight by 0.05. Record the calculated load and the actual load used. ### Should both sides be tested? Yes, when side-to-side comparison is relevant. ### What is a good score? There are no universal norms. Use baseline comparison, side-to-side comparison and repeat the exact same protocol over time. ## Key Takeaways The Shoulder External Rotation – Hold 5% BW Test assesses sustained loaded external rotation endurance. The primary score is hold time in seconds. Load, arm position, elbow position, ROM and equipment must be standardised. The test should not be treated as isolated rotator cuff endurance. Measurz can track body weight, load, hold time, side, symptoms, compensation and retest progress. ## References Kardor, S., Gorji, Z., Ghotbi, N., Attarbashi-Moghadam, B., Shadmehr, A., & Gorji, M.
