Dogma of Running Injuries - Perceptions of High School Runners

🎙️ Episode Overview Host: Evan Nelson, Associate Professor at the University of Wisconsin Guests: Dr. Micah Garcia, Assistant Professor at Thomas More University, expert in youth running biomechanics and injury prevention. Coach Matt Cooper, Head Cross Country Coach at Verona High School, Verona, Wisconsin. 🧠 Topic: Perceptions of Running-Related Injuries This episode explores how adolescent and adult runnersperceive the causes and prevention of running injuries, based on the 2024 study: “The Dogma of Running Injuries: Perceptions of Adolescent and Adult Runners” [https://nata.kglmeridian.com/view/journals/attr/59/9/article-p955.xml] (Journal of Athletic Training). 📊 Study Highlights Participants: 659 runners (ages 9+), globally recruited. Groups: Adolescents (≤19 years) vs. Adults (≥20 years). Method: Survey on beliefs about injury risk and prevention. 🧩 Key Findings ✅ Commonly Perceived Risk Factors: Poor bone health, low calcium, negative caloric intake Tight muscles, hard surfaces, narrow steps, high-mileage shoes Previous injury (strongest evidence-supported risk) ✅ Commonly Perceived Protective Factors: Stretching (dynamic before, static after) Strong legs/core, cross-training, cushioned shoes Taking rest/off days 🔍 Adolescents vs. Adults: Adolescents emphasized footwear, stretching, and surface. Adults emphasized overtraining and strength training. 🧪 Evidence-Based Truths Only strong evidence: Previous injury increases future injury risk. Inconclusive evidence: Most other factors (e.g., stretching, footwear, cadence). Cadence: Lower cadence linked to shin injuries in adolescents (emerging evidence). Strength training: Valuable for performance and bone health, though not conclusively injury-preventive. 🧠 Coach & Researcher Insights Coach Cooper: Emphasizes education, strength training, and athlete buy-in. Plans to use fatigue curves and alumni talks to improve understanding. Dr. Garcia: Encourages bridging the gap between research and coaching. Notes that beliefs often influence behavior—except in nutrition, where awareness didn’t match action. 🧰 Practical Takeaways Coaches: Use athlete-friendly education, visuals, and peer examples. Researchers: Simplify findings, attend coaching clinics, and collaborate with coaches. Everyone: Be curious, adaptable, and evidence-informed.

Which Training Log is Accurate? GPS watches vs Athlete Reported Training

🎙️ Podcast Overview Host: Evan Nelson, Associate Professor at theUniversity of Wisconsin Guests: Dr. Micah Garcia, Assistant Professor at Thomas More University, expert in youth running Coach Charlie Burnham, Girls' Cross Country Coach at Burnsville High School, Burnsville, MN 🏃‍♂️ Topic: MeasuringTraining Load in High School Cross Country Runners The episode explores how to best track training loads inhigh school runners, comparing GPS watches and electronictraining journals. 📊 Key Concepts External Load: Objective measures like distance and time. Internal Load: Subjective or physiological responses like perceived exertion or heart rate. 📄 Study Summary Title: “Global Positioning System Watches and Electronic Journals: Are Training Load Measures Similar in High School Cross Country Runners?” [https://journals.humankinetics.com/view/journals/ijspp/17/7/ijspp.2021-0563.xml] Published: 2022, International Journal of Sports Physiology and Performance Authors: Dr. Micah Garcia & David Bazzett-Jones 🔍 Purpose: To compare data from GPS watches and electronic journals toassess consistency in tracking training loads. 📈 Findings: GPS watches provided more consistent and complete data for external loads. Journals often had missing entries (about 1/3 of GPS-recorded runs were not journaled). When both sources were available, journal entries tended to overreport distance and time by ~10%. Internal load (perceived exertion vs. heart rate) showed poor agreement—heart rate data from wrist-based GPS watches was often inaccurate. 🧠 Insights from Dr. Garcia GPS watches are more reliable for external load tracking. Subjective perceived exertion may be more accurate than wrist-based heart rate for internal load. Coaches should choose tools based on their goals and available resources. 🏫 Coaching Perspectivefrom Coach Burnham Prioritizes external load (time and distance), especially time-based training for inclusivity. Uses a Google spreadsheet for summer training logs; less structured during the season. Emphasizes fun, consistency, and long-term love for the sport over strict data tracking. Notes challenges with technology access, motivation, and accuracy among high school athletes. 🧩 Practical Takeaways GPS watches are effective for capturing external load but may not reflect perceived effort. Self-reported intensity is valuable but requires routine and motivation. Coaching context matters: team size, athlete experience, and program goals influence the best tracking method.

Week-to-Week Changes in Running Volume Were Not Related to Risk of Sustaining a Running Injury in High School Distance Runners

🎙️ Podcast Summary:Science on Track – Week-to-Week Changes in Running Volume Host: Evan O. Nelson Guests: • Dr. Mikel Joachim – Research Program Manager, University of Wisconsin • Coach Jane Wheeler – Head Girls Cross Country Coach, Pleasant Valley High School, Bettendorf, Iowa 🧪 Study Overview The episode centers on a research study titled: “Week-to-week changes in training were not prospectively associated with injuries among Wisconsin High School cross-country runners” (published in Injury Prevention, 2024). [https://injuryprevention.bmj.com/content/early/2024/07/31/ip-2024-045233] https://injuryprevention.bmj.com/content/early/2024/07/31/ip-2024-045233 🔍 Study Purpose To investigate whether week-to-week changes in trainingvolume (distance, duration, intensity) are associated with injury risk in high school cross-country runners. 📊 Key Findings • No significant association was found between week-to-week changes in training volume and injury risk. • Most runners in the study averaged 20–30 miles per week, with few exceeding 50 miles. • Preseason training had a strong protective effect: • Every additional 5K (~3 miles) run per week in the preseason reduced injury risk by 17%. • Coaches’ day-to-day training modifications likely play a major role in injury prevention, even if not captured in weekly data. 🧠 Insights from theGuests 🧑‍🔬 Dr. MikelJoachim: • Null results suggest that current coaching practices in Wisconsin high school programs are effective in managing injury risk. • The study relied on daily text surveys during COVID, with athletes self-reporting training and injuries. • Emphasized the importance of holistic athlete monitoring, including stress, sleep, and other sports participation. 🏃‍♀️ Coach Jane Wheeler: • Reinforced the importance of individualized coaching and preseason preparation. • Noted that injury risk is multifactorial, often influenced by training history, biomechanics, and external stressors. • Advocated for flexibility in coaching and communication with athletes to adapt training in real time. 🧩 PracticalTakeaways for Coaches • Preseason training matters: Encourage consistent summer/winter running to reduce injury risk. • Small weekly increases (up to 30%) in training volume appear safe. • The 10% rule is not strongly supported by evidence—coaches can be more flexible. • Monitor athletes holistically: Consider stress, sleep, and other commitments. • Build strong coach-athlete relationships to better detect and respond to early signs of injury.
