Shoulder endurance is important in overhead sport, gym training, work tasks and athletic positions requiring repeated arm elevation. While maximal strength tests show peak force capacity, repetition-based endurance tests provide additional information about fatigue tolerance and repeatability under load. The 10% bodyweight version is a higher-load option. It may be appropriate for stronger clients, athletic clients or clients who can maintain a consistent shoulder flexion pattern under load. The result should be interpreted alongside symptoms, shoulder range of motion, shoulder strength, shoulder external rotation endurance, shoulder flexion hold testing, overhead tasks and training demands. ## Quick Summary Test name: Shoulder Flexion – Reps 10% BW Category: Shoulder flexion endurance Load: 10% of body weight Primary score: Valid repetitions completed Best use: Higher-load shoulder endurance testing, baseline comparison and retesting Key limitation: It is load- and protocol-specific and may not suit clients with high shoulder irritability ## What Is This Assessment? The Shoulder Flexion – Reps 10% BW Test assesses how many controlled shoulder flexion repetitions a client can complete using a load equal to 10% of their body weight. The test may be performed using a dumbbell, cable, plate or other measurable load, provided the setup is standardised. For example, a 70 kg client would use a 7 kg load if following a true 10% bodyweight protocol. The exact load should be rounded and recorded according to available equipment. ## Why It Is Used The test may be used to assess: Shoulder flexion endurance Repeated arm elevation tolerance Fatigue response under a scaled load Baseline and retest change Symptom response during repeated flexion Technique change under fatigue Higher-load shoulder endurance capacity It is most useful when the same load calculation, equipment, ROM, tempo and stopping criteria are repeated. ## What It Measures The primary score is valid repetitions completed. The result may reflect: Shoulder flexion endurance Anterior shoulder loading tolerance Upper-limb fatigue tolerance Scapular and trunk control ROM consistency Pain or symptom response Technique control under fatigue Motivation and familiarisation It should not be described as isolated anterior deltoid endurance because shoulder flexion involves multiple muscles, scapular control, trunk control and load position. ## Who It Is Useful For The test may be useful for: Overhead athletes Gym clients Field sport athletes Swimming and racquet sport clients Clients with repeated reaching demands Workplace or tactical clients with shoulder loading demands Professionals monitoring shoulder endurance over time It may not be suitable for clients with high shoulder irritability, poor shoulder flexion ROM, pain during loaded elevation, poor control under load or inability to maintain the required position. ## Equipment Required Dumbbell, plate, cable or measurable load Scale or known body weight Calculator for 10% bodyweight load Measurz rep counter Optional Measurz metronome Optional Measurz stopwatch if time-limited Measurz platform for load, reps, symptoms, compensation and retest comparison ## Step-by-Step Protocol 1. Record the client’s body weight. 2. Calculate 10% of body weight. 3. Select the closest practical load and record the exact load used. 4. Choose the test position: standing, seated or supported. 5. Record grip, equipment type, arm tested, ROM target and tempo. 6. Start with the arm in the standardised start position. 7. Ask the client to lift into shoulder flexion to the selected ROM. 8. Lower with control to the start position. 9. Count only valid repetitions that meet the ROM and technique criteria. 10. Stop when ROM is lost, technique changes, cadence is missed, symptoms become unacceptable or the client chooses to stop. 11. Record valid repetitions and reason for stopping. ## Scoring and Interpretation Record: Body weight Calculated 10% load Actual load used Arm tested Valid repetitions ROM target Tempo or cadence Equipment type Body position Pain or symptoms Technique changes Compensations Reason for stopping Retest date A higher repetition score generally suggests greater shoulder flexion endurance under the 10% bodyweight protocol. However, interpretation should consider load rounding, ROM, fatigue, symptoms, trunk compensation and technique quality. The most useful comparison is usually the client’s own baseline using the same setup. ## Normative Data, Benchmarks or Reference Values There are no widely accepted universal norms for Shoulder Flexion – Reps 10% BW across all populations. Use practical field bands only when the same protocol is repeated: 30+ valid repetitions: strong current endurance 15–29 valid repetitions: moderate current endurance 5–14 valid repetitions: developing current endurance Under 5 valid repetitions: low current endurance These are practical guide ranges only. Baseline 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, ROM, tempo, equipment type, warm-up, instructions and stopping criteria. The 10% BW protocol provides a standardised way to scale shoulder endurance 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 flexion endurance under load, but it should not be used alone to diagnose shoulder pathology, injury risk or readiness. ## Common Errors and Limitations Common errors include: Incorrect bodyweight load calculation Not recording actual load used Changing equipment type Changing ROM Using momentum Leaning backwards Shrugging the shoulder Bending the elbow more as fatigue develops Using inconsistent tempo Counting partial reps Ignoring symptoms Comparing 5% and 10% BW tests directly Limitations include load rounding, equipment availability, fatigue, motivation, symptom irritability and influence from trunk and scapular control. ## Practical Applications The Shoulder Flexion – Reps 10% BW Test can help professionals: Monitor higher-load shoulder flexion endurance Track repeated arm elevation tolerance Compare baseline and retest performance Record fatigue response Identify compensation under load Guide endurance-focused programming Compare shoulder flexion reps with shoulder flexion hold or external rotation endurance results It is most useful when interpreted alongside shoulder ROM, shoulder strength, external rotation endurance, push-up testing, overhead symptoms and sport or work demands. ## How to Record This in Measurz / MAT Record: Test name Body weight Calculated 10% load Actual load used Side tested Repetitions completed ROM target Tempo or cadence Equipment type Body position Pain score Symptom location Technique changes Compensation Reason for stopping Retest date Use the Measurz rep counter for repetitions and the metronome for cadence control. Use AR measurement or the inclinometer to help document ROM or arm angle where useful. ## FAQs ### What does Shoulder Flexion – Reps 10% BW measure? It measures shoulder flexion endurance using a load equal to 10% of body weight. ### Is it an isolated shoulder flexor test? No. It involves shoulder flexors, scapular control, trunk control and technique under fatigue. ### How is the load calculated? Multiply body weight by 0.10. Record the calculated load and the actual load used. ### What is a good score? There are no universal norms. Use baseline comparison and repeat the exact same protocol over time. ### Should symptoms be recorded? Yes. Record pain, fatigue, ROM loss, compensation and reason for stopping. ## Key Takeaways The Shoulder Flexion – Reps 10% BW Test assesses loaded shoulder flexion endurance. The primary score is valid repetitions completed. Load, ROM, tempo and equipment must be standardised. The result should not be treated as an isolated shoulder muscle test. Measurz can track body weight, load, reps, symptoms, compensation and retest progress. ## References Kardor, S., Gorji, Z., Ghotbi, N., Attarbashi-Moghadam, B., Shadmehr, A., & Gorji, M. (2023).
