Eccentric Biceps Exercises for Tendinosis Rehabilitation
Direct Answer
For biceps tendinosis rehabilitation, perform slow lowering (eccentric) biceps curls with a dumbbell or resistance band, taking 3 seconds to lower the weight from full elbow flexion to full extension, starting with 1 set of 10-15 repetitions and progressing to 3 sets performed 2-3 times per week on non-consecutive days. 1
Specific Exercise Technique
Primary Exercise: Eccentric Biceps Curl
- Starting position: Hold a dumbbell or resistance band with elbow fully flexed (biceps contracted) 2
- Eccentric phase: Lower the weight slowly over 3 seconds to full elbow extension 1
- Return phase: Use the opposite arm to assist lifting the weight back to starting position, or perform a normal concentric curl 2
- Maintain full range of motion throughout the movement 1
Exercise Variations by Position
- Standard position: Elbow at side, forearm supinated (palm up) 2
- Alternative position: Perform in different degrees of elbow flexion to target the distal biceps tendon specifically 2
- Both positions should be incorporated into the rehabilitation program 2
Dosage and Progression Protocol
Initial Phase (Weeks 1-2)
- Frequency: 2-3 non-consecutive days per week 1
- Sets/Reps: Start with 1 set of 10-15 repetitions 1
- Speed: 3-second eccentric (lowering) phase 1
- Resistance: Begin with minimal weight that allows proper form 1
Progression Criteria
- Advance to 3 sets once initial volume is tolerated with minimal pain 1
- Increase resistance gradually only when exercises can be performed with minimal pain 1
- Mild discomfort during exercise is acceptable, but pain should not persist after exercise 1
Critical Implementation Guidelines
Pain Monitoring
- Acceptable: Mild discomfort during the exercise itself 1
- Unacceptable: Pain that persists after completing the exercise session 1
- Warning sign: Increased pain indicates progression is too rapid 1
Breathing Technique
- Exhale during the eccentric (lowering) phase of the movement 1
- This helps maintain proper form and prevents Valsalva maneuver 1
Speed Control
- Perform at moderate to slow controlled speed throughout 1
- The 3-second eccentric phase is non-negotiable for therapeutic effect 1
Complementary Interventions
Adjunctive Treatments to Combine with Eccentric Exercise
- Stretching: Perform wrist extensor and biceps muscle stretching 1
- Cryotherapy: Apply ice through a wet towel for 10 minutes after exercise for pain relief 1
- Relative rest: Avoid activities that reproduce pain, but do not completely immobilize 1
- Deep transverse friction massage: May provide additional pain relief 3
Evidence from Clinical Cases
A case series of 10 patients with chronic biceps tendinopathy treated with eccentric-concentric exercise combined with dry needling and stretching showed mean pain reduction of 3.9 points and functional improvement of 19% on QuickDASH scores 4. A single case report of distal biceps tendinosis treated primarily with eccentric training in two elbow positions over 4 weeks demonstrated decreased pain, increased strength, and clinically significant QuickDASH improvement 2.
Mechanism of Action
Why Eccentric Exercise Works
- Stimulates collagen production in the tendon 1
- Guides normal alignment of newly formed collagen fibers 1
- Tensile loading promotes tendon healing and remodeling 1
- Reduces symptoms while simultaneously increasing strength 3, 1
Common Pitfalls to Avoid
Do Not:
- Completely immobilize the arm, as this leads to muscle atrophy and deconditioning 1
- Progress resistance too quickly, which can worsen symptoms and delay healing 1
- Continue if pain persists after exercise sessions 1
- Skip the slow eccentric phase, as speed is critical to therapeutic effect 1
Do:
- Maintain activities that do not reproduce pain to prevent deconditioning 1
- Monitor pain levels closely and adjust accordingly 1
- Progress gradually based on symptom response, not arbitrary timelines 1
Expected Timeline
Most patients with tendinosis respond to eccentric training within 3-6 months when performed consistently with appropriate progression 5. The key is patient comprehension, motivation, and adherence to the specific loading parameters outlined above 6, 7.
