Research Deep-Dive: Hamstring Strength & Running Biomechanics

This episode reviews the study: “Hamstring Strength and Architectural Properties Are Associated with Running Biomechanics”, including findings from ultrasound imaging, EMG analysis, and 3D running mechanics. 

Key Study Questions

• Do stronger hamstrings create better running mechanics?
• Do better mechanics help build stronger, longer hamstrings?
• How do strength, fascicle length, pelvic position, and muscle activation interact?

🔎 Main Findings From the Study

1. Stronger Hamstrings = Better Running Mechanics

Athletes with higher eccentric hamstring strength had:

• Higher stride frequency (cadence)
• Better control of decelerating the swinging leg
• Lower ground contact time (improved efficiency)
• Lower hamstring activation at sub-max speeds → reduced overload 

2. Longer Hamstring Fascicles = Safer, More Efficient Loading

Runners with longer fascicle lengths showed:

• Less anterior pelvic tilt
• Lower hamstring activation
• Better ability to tolerate late-swing loading (a high-irritation phase for PHT) 

3. A Two-Way Relationship Exists

Strength ↔ mechanics influence each other.

• Stronger hamstrings → better running technique
• Better running technique → better hamstring loading → stronger, longer muscle structure over time
   This creates a positive adaptation loop. 

4. Over-Reliance on the Biceps Femoris = Red Flag

Runners with weak or short hamstrings tended to over-activate the biceps femoris long head — the most common site of PHT.
Stronger runners shared load better with the medial hamstrings, reducing tendon stress. 

🏃 Practical Rehab Takeaways

1. Build Eccentric Strength

Eccentric strength is one of the strongest predictors of hamstring injury risk.
 Examples Brodie recommends:

• Hamstring sliders
• Weighted eccentric sliders
• Single-leg sliders
• Assisted → full Nordic drops
• Deadlifts (when tolerated) 

2. Improve Fascicle Length

Eccentric exercises at long muscle lengths help lengthen fascicles naturally — more so than stretching alone.

3. Strengthen the Medial Hamstrings

To prevent overload of the biceps femoris:

• Use toes-in hamstring curls
• Toes-in sliders
• Toes-in deadlift variations
   These help redistribute load more evenly across the tendon. 

4. Slightly Increase Cadence (~5%)

A small increase in stride frequency may reduce late-swing strain and improve running economy.

5. Integrate Running Into Rehab

Before adding speed:

• Build to 30 minutes continuous, easy running → symptom-free
  Then introduce:
• Strides (15–20 sec at ~75% speed, 4 reps)
• Gradual progression based on symptoms the next day 

Final Thoughts

Hamstring strength, muscle architecture, and running technique are deeply interconnected. Improving one helps improve the others — creating a pathway toward better performance and long-term PHT resilience.

🧠 Episode Summary

In this episode, Brodie dives into a newly published paper titled “Female Tendons are from Venus and Male Tendons are from Mars: But Does it Matter for Tendon Health?” by Gerard McMahon and Jill Cook. The paper explores how male and female tendons differ in structure, adaptation, healing, and injury risk—and what it means for those dealing with tendinopathy.

🔍 What You’ll Learn

• Key structural differences between male and female tendons (size, stiffness, collagen synthesis)
• Why female tendons may stretch more but adapt less to training
• How men and women respond differently to tendon rehab protocols
• Surprising findings about pain, healing, and tendon blood flow
• Whether injury prevention or rehab should differ based on sex

📌 Key Takeaways

• Female tendons are more compliant, have lower stiffness, and show slower collagen production—even at rest.
• Male tendons respond more favorably to traditional rehab (like eccentric loading), often reporting greater pain reduction and functional improvements.
• Despite men experiencing more frequent tendon injuries in some data, women may be closer to their strain “danger zone” during exercise, possibly increasing injury risk.
• Women may need longer rehab timelines, heavier resistance training (beyond just eccentrics), and closer attention to recovery, nutrition, and hormonal cycles.
• Men should be cautious about overloading tendons due to higher force-generating capacity and should still progress gradually.

💡 For Runners With Tendinopathy

• Don’t compare your progress to someone of the opposite sex—recovery is sex-specific.
• Trust the process: healing may be happening at a microscopic level even if pain relief is slow.
• Tailor your rehab by considering not just gender, but also age, training history, injury severity, and more.
