Latest Research: Ketones & Running Performance, HIIT vs Steady Runs, Hip Strength For Better Mechanics

Brodie Sharpe reveals how his podcast deciphers running research to help you break through injury cycles.

This episode of The Run Smarter Podcast presents Brodie Sharp's analysis of three recent scientific studies relevant to runners. Brodie is a physiotherapist and coach who aims to translate complex research into practical guidance. He selects papers he finds most interesting and impactful for a runner's training and health. The first paper examined the effects of ketone ester supplementation on the performance of elite male cyclists during a simulated time trial. A second study investigated the relationship between hip extension range of motion and running economy in collegiate distance runners. The third paper explored the connection between bone stress injuries and measurements of the femur's bending strength in female cross-country runners. The ketone study involved cyclists completing a 30-minute time trial after consuming either a ketone ester or a placebo drink. Researchers found the ketone supplement did not improve time trial performance compared to the placebo. The hip extension study used 3D motion capture to measure runners' mechanics and a treadmill test to assess running economy. It concluded that greater passive hip extension did not correlate with better running economy in the tested athletes. The bone stress injury research analyzed MRI scans to calculate the femoral bending strength index in athletes. It reported that a lower bending strength index was associated with a higher incidence of femoral stress fractures. Brodie notes the practical challenge of obtaining such detailed MRI measurements in a typical clinical setting. He emphasizes that these studies provide specific insights but rarely offer universal, immediately applicable answers for every runner. Brodie finds it interesting that the ketone study, despite hype around ketones for performance, showed no benefit in this specific cycling protocol. He points out that the hip extension research contradicts a common belief in running circles about its importance for efficiency. The bone study highlights a potential anatomical risk factor, suggesting some athletes may have inherently weaker bone structures predisposing them to injury. The episode maintains an educational and analytical tone, systematically breaking down each study's methodology and findings. Brodie's style is conversational and explanatory, focusing on translating academic language for a lay audience. Runners interested in the science behind training, nutrition, and injury prevention will find this episode valuable. Listeners seeking simple, definitive training tips or narrative storytelling might find the technical, research-focused approach less engaging.
