Whether you're a recreational runner or an aspiring marathoner, these findings offer practical, science-backed takeaways.Featured Studies & Key InsightsAsymmetry & Bone Stress InjuriesStudy Title: Can biomechanical variables and asymmetry predict bone stress injuries in collegiate distance runners?✅ Key Finding: Even small left-to-right asymmetries may increase injury risk — particularly for female runners.🧍‍♂️ Implication: Asymmetry under 10% was still meaningful in injury prediction. Don’t ignore minor imbalances in cadence, step length, or ground reaction force.🧠 Tip: Wearables that track contact time or vertical oscillation may help identify early imbalances before pain begins.Strength & Flexibility Self-Assessments for MarathonersStudy Title: Strength and Flexibility Self-Assessment and Subsequent Training Injuries Among Recreational Runners of the NYC Marathon✅ Key Finding: The single-leg glute bridge was the only test significantly associated with injury risk.❌ Flexibility tests (sit & reach, quad stretch) and other strength tests (planks, heel raises, push-ups) had no predictive value.🏠 DIY Test: If you can’t hold a single-leg glute bridge for >20 seconds on your weaker side, your injury risk may be higher.Super Shoes & Injury RiskStudy Title: Technology Advanced Running Shoes Reduce Biomechanical Factors of Running-Related Injury Risk👟 Super shoes (like Nike Alphafly) encouraged mid/forefoot striking without increasing joint or muscle strain.✅ They reduced load on key areas like the ankle joint, soleus, and peroneus longus.❗️Minimalist shoes, on the other hand, tripled ankle joint forces and heavily loaded the calf and foot — a risk for Achilles and metatarsal injuries.⚠️ Caution: Transition slowly into super shoes or minimalist footwear. Your body needs time to adapt to new mechanics.Practical Takeaways for RunnersMonitor asymmetries using wearables or self-awareness — don’t wait for pain.Use the glute bridge hold as a simple strength test at home. Aim for >20 seconds on both sides.Super shoes aren’t just for speed — they may actually help with injury prevention, especially for habitual forefoot strikers.Avoid going cold turkey into minimalist shoes unless you're conditioned for it.📚 Want to Go Deeper?🔍 All referenced studies are stored in the Run Smarter Research Database — accessible for just $8.99/month. 💬 Plus, get access to the Run Smarter AI Assistant, which answers your running questions based on podcast episodes, papers, and course content.👉 Click here to explore membership optionsFor MORE Run Smarter Resources 🏃‍♂️📚- Including Free Injury Prevention Courses 🩹🎓- The Run Smarter Book 📖- Access to Research Papers 📄🔍- & Ways to Work with Brodie 🤝👟👉 CLICK HERE! 🎉✨ 

Learn more about Brodie's Research Database & AI Assistant 📄🔍In this episode of the Run Smarter Podcast, Brodie sits down with world-renowned sports dietitian and researcher Professor Louise Burke to clear the air on one of the most debated topics in endurance sport: low-carb vs high-carb diets.After receiving listener pushback from a previous episode on low-carb nutrition, Brodie brings in Louise — who has decades of elite-level experience and research — to explore:The theory behind fat-adaptation and low-carb, high-fat dietsWhether the science supports keto for endurance performanceThe trade-offs between fuel efficiency, oxygen use, and high-intensity outputWhat recreational runners should consider when planning their fueling strategiesLouise also shares:When keto may be appropriate (hint: not for everyone!)How to train your gut to tolerate more carbsThe dangers of extreme diet restrictionWhy individual response should guide your nutrition planHer concerns around misinformation, particularly in female athlete nutrition🧠 Key Takeaways:Yes, keto increases fat burning, but it can impair high-intensity performance due to reduced oxygen efficiency.Carb periodisation—adjusting intake based on session intensity—is a smart strategy for most runners.Carbohydrate source and quality matter just as much as quantity.Training the gut is essential if you're increasing carb intake for race day.Avoid extreme rigidity in diets. Nutrient density, food range, and enjoyment are critical for long-term success.💬 Quotes to Remember:“It’s not about choosing sides — it’s about choosing the right strategy for your sport, goals, and physiology.”“Everyone’s an expert in nutrition… because everyone eats. But not everyone interprets the science correctly.”Follow Prof Louise Burke on Twitter (X)For MORE Run Smarter Resources 🏃‍♂️📚- Including Free Injury Prevention Courses 🩹🎓- The Run Smarter Book 📖- Access to Research Papers 📄🔍- & Ways to Work with Brodie 🤝👟👉 CLICK HERE! 🎉✨
