How to quantify the training load of higher intensities and sprints, separately from aerobic training load, simply from power data? We suggest a 3D strain score (alternative to the "1D" TSS/TRIMP/work -> fitness paradigms) to capture the nuances of training CP, W', and Pmax.

When does resistance exercise become endurance exercise? 🏋️↔️🏃 It might depend on the critical occluding tension in our muscles 💪🩸 🧵/ 📚link👇 A Critical Occluding Tension Phase Transition Occurs Between 30-40% 1RM in Dynamic Knee Extension Exercise

New paper on using D2O to measure hemoglobin synthesis rates in humans! We explained this application of D2O in @Acta_Physiol onlinelibrary.wiley.com/doi/10.1111/ap… and use it here to show no influence of training status. Reach out if you're interested in this method.
Hilkka Kontro@HilkkaKontro

New! We measured rates of hemoglobin synthesis in trained and untrained individuals and found them to be similar despite some earlier work showing shorter RBC lifespan in athletes. @MartinMacInnis physoc.onlinelibrary.wiley.com/doi/10.14814/p…
