Sports science, distilled.
Summaries and analysis of key research papers in sports science, velocity-based training, and performance measurement.
Power-Time Curve of the Clean: An 800Hz IMU Analysis of First Pull, Transition, and Second Pull
The clean's power-time curve puts 60-70% of total power in the second pull. See how 800Hz IMU data from PoinT GO breaks down each phase of the lift.
Why Bar Velocity Drops in the Final Rep: A Neuromuscular and Metabolic Analysis
That final-rep grind isn't just in your head. Neuromuscular fatigue, metabolic byproducts, and motor unit changes all show up clearly in the velocity data.
Why Cluster Sets Preserve Velocity Better: The Neuromuscular Science of Distributed Rest
Traditional sets bleed bar speed rep after rep. Cluster sets hold velocity 12% higher by spacing micro-rests, per neuromuscular and 800Hz VBT evidence.
Why CMJ Outperforms SJ for Daily Athlete Monitoring: A Neuromuscular Fatigue Comparison
Squat jump misses what countermovement jump catches. CMJ tracks neuromuscular fatigue 2.3x more sensitively, per longitudinal IMU monitoring evidence.
Why Deload Frequency Matters More Than Intensity: A VBT-Driven Research Review
Cutting intensity isn't the lever that matters most for recovery — deload frequency is. Six RCTs re-read through IMU and VBT data confirm it.
Why Eccentric Overload Builds Tendons: The Collagen Remodeling Science
Concentric-only training leaves tendon stiffness behind. Eccentric overload roughly triples the gain via collagen remodeling — biology and an IMU protocol.
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 Female Athletes Need Different VBT Protocols: 800Hz IMU Sex-Specific Velocity Research
Load-velocity profiles aren't interchangeable between sexes. 800Hz IMU data shows where female athletes diverge, plus how the cycle shifts velocity zones.
Why the Isometric Mid-Thigh Pull Matters: The Gold Standard for Maximum Strength Assessment
The isometric mid-thigh pull remains the gold standard for peak force and RFD testing. See how IMU sensors extend IMTP data into daily velocity tracking.
Why Knee Flexion Angle Determines Jump Height: Biomechanical Analysis of Countermovement Depth
Knee flexion angle in the countermovement jump shifts jump height more than most realize. Here's the optimal depth range and why it varies by athlete.
Why Rotational Power Asymmetry Matters: Injury Risk and Performance in Throwing and Striking Sports
A 15% left-right power gap triples injury risk in golf, baseball, and tennis. See the longitudinal IMU thresholds and protocols behind that number.
Why 30% Velocity Loss Is the Best VBT Cutoff: A Meta-Analysis of Pareja-Blanco and Beyond
Stop guessing when to end a set. Pareja-Blanco's data shows a 30% velocity loss cutoff balances hypertrophy and power better than VL10, VL20, or VL40.
