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.
Squash Lunge Asymmetry: What a Dominant-Diagonal Deceleration Bias on IMU Data Really Means
A clean lunge asymmetry score can hide a leg that brakes and returns slower on the same corner every time. See the IMU protocol and cutoffs that catch it.
Weight-Bearing Lunge Test: Ankle Dorsiflexion Norms and What Side-to-Side Asymmetry Actually Means
Knee-to-wall distance norms for the weight-bearing lunge test, plus the asymmetry cutoff (cm) research links to ankle sprain recurrence and reinjury risk.
Muscle Imbalance and Injury Risk: Bilateral and Agonist-Antagonist Ratios
Soccer players with over 15% bilateral asymmetry saw a 2.6x higher hamstring strain rate next season. This review maps the thresholds that hold up.
How to Measure Jump Asymmetry: PoinT GO Injury Risk Screening
A single-leg jump test can flag ACL and hamstring injury risk before it happens. Here is the CMJ protocol and limb symmetry index PoinT GO uses.
Isometric Strength Deficits as Injury Risk Predictors: Evidence Review
A 423-athlete cohort found isometric limb symmetry under 90% predicted 2.4x higher hamstring injury odds. How to test it and act on the number in-season.
