First, a randomized controlled trial on ketone supplementation reveals that while ketones significantly improve cognitive function—helping with reaction time and mental clarity—they do not improve running performance, efficiency, or fuel utilization . Despite feeling better during efforts, runners didn’t run faster, and some even experienced gastrointestinal issues, raising questions about their real-world value for endurance athletes. Next, Brodie explores a meta-analysis comparing high-intensity interval training (HIIT) vs moderate continuous running (MICT) . The key takeaway: HIIT is more effective at improving running economy (efficiency at submax speeds) , particularly at moderate intensities, while steady running is better for improving VO₂ max (your aerobic engine) . This reinforces the idea that both training styles serve different physiological purposes—and combining them strategically is the smartest approach for performance gains. Finally, a newly released review challenges one of the most common rehab narratives: that weak glutes cause poor running mechanics . Across 19 studies, there was no consistent link between hip strength and running biomechanics , and even strengthening programs failed to meaningfully change running form. Instead, Brodie reframes strength training as a way to increase load capacity , no…
