Summaries and analysis of key research papers in sports science, velocity-based training, and performance measurement.
Why Rep-by-Rep Velocity Stabilization Matters: Reliability and Adaptation Signals in VBT
When rep-to-rep velocity variation drops below a 5% coefficient of variation, that is your sign neuromuscular adaptation is locking in, per 800Hz IMU data.
Why Warmup Jumps Predict Performance: The Science of Neuromuscular Readiness
A flat warmup jump can be an early warning sign. RSI and jump-height shifts during warmup forecast same-day performance via 800Hz IMU tracking.
Force Deck vs IMU: Jump Measurement Accuracy, Metric Agreement, and Field Reality
A lab-grade force plate and an 800Hz IMU can still disagree on jump height. See the ICC, Bland-Altman limits, and which tool is accurate enough.
Why Bar Path Tracking Matters: 3D Kinematics and Lift Efficiency
Bar path reveals lift efficiency and injury risk long before you feel it. See 800Hz IMU kinematics across squat, deadlift, and clean movements.
Why the Bench Press Arch Helps: ROM Reduction, Scapular Stability, and Power Transfer Biomechanics
A proper thoracic arch shortens ROM by 12-18% and adds 5-8% to your bench 1RM. Here's the scapular retraction mechanics and IMU bar-speed data behind it.
Why Cluster Sets Outperform Straight Sets for Power: An 800Hz IMU Meta-Analysis
Twelve studies, one pattern: cluster sets beat straight sets on velocity, RFD, and power output. See the 800Hz IMU meta-analysis behind the gains.
Why Couplet Training Saves Time: The Neurophysiology of Antagonist Supersets
Pairing antagonist exercises trims session time 47% while 1RM and power output hold steady — the neurophysiology and 800Hz IMU verification data.
Why Eccentric Training Builds More Muscle: From Molecular Biology to IMU Measurement
Mechanical tension alone doesn't explain eccentric training's hypertrophy edge. Muscle damage and satellite activation close the gap, per new research.
Why Explosive Intent Matters on Every Rep: The Neuromechanics of Intent-Velocity-Adaptation
Lifting light doesn't mean lifting slow. Maximal accelerative intent shifts motor unit recruitment and firing rate even at light loads, per new evidence.
Why Female Athletes Need Power Training: Hormonal, Neuromuscular, and Injury-Prevention Evidence
Neuromuscular profile, ACL injury risk, and hormonal cycling point one direction: power training isn't optional for female athletes. The integrated case.
Why Isokinetic Machines Are Overrated: The 800Hz IMU Paradigm Shift in Strength Assessment
Isokinetic machine limitations show up fast under real sport loads—Cybex and Biodex miss what 800Hz IMU sensors capture in the field. Here's the evidence.
Why Isometric Training Builds Tendons: The Science of Collagen Adaptation Through 800Hz IMU Data
Isometric training strengthens tendons through collagen remodeling that isotonic lifting can't match. 800Hz IMU data shows the loading pattern that works.
