Hamstring-to-Quadriceps Isokinetic Ratio Test: Reading Injury Risk Beyond the Sprint Score
A H:Q ratio under 0.47 or a 15% bilateral gap flags real hamstring injury risk on isokinetic testing. Here is the full protocol, norms, and interpretation.
Why Eccentric Velocity Predicts Injury: A VBT-Based Risk Monitoring Research Review
A 12% rise in eccentric velocity over four weeks is tied to a 2.8x jump in hamstring injury risk. See how 800Hz IMU tracking flags it early.
Why Jump Asymmetry Is the Strongest Predictor of Injury Risk: The Science of Asymmetry via 800Hz IMU
Jump asymmetry outpredicts every other test for ACL and hamstring injury. Twelve studies and 800Hz IMU data show why balance testing alone falls short.
