Sports science, distilled.
Summaries and analysis of key research papers in sports science, velocity-based training, and performance measurement.
Eccentric Overload Training: Power & Injury Prevention
Eccentric overload training for athletic power, fascicle length, tendon health, and hamstring injury prevention — with practical protocols.
Jump Training Dose-Response: How Much Is Enough?
A 53-study meta-analysis found 2-3 weekly plyo sessions beat 1 or 4+ for vertical jump gains. Foot-contact volumes and dosing thresholds inside.
Post-Activation Potentiation (PAP): Science & Application
A research-backed look at post-activation potentiation: the mechanism, optimal rest windows, complex-training protocols, and how to find your PAP window.
Jump Height Measurement Methods: Accuracy Comparison Study
Jump mats read 4.6cm higher than force plates on average. Compare force plate, IMU, video, and mat error rates to pick the right tool for your context.
Jump Height Measurement Methods: Flight Time vs Force Plate
The h = g x t^2/8 formula assumes equal takeoff and landing height. Hip pike and knee bend break that and skew results 1-3cm. IMU validation data inside.
Minimal Dose Plyometrics: How Little Training Can Still Work?
You do not need high jump volume to get stronger off the ground. This review covers the minimal effective dose backed by force-velocity data.
Velocity-Based Training for Autoregulation: What Research Shows
Pareja-Blanco's 8-week trial pitted 20% velocity loss against 40%, and the gap in results reshaped how autoregulation gets programmed today.
VBT Autoregulation Study: Velocity-Based Load Management
Instead of guessing today's working weight, VBT autoregulation adjusts load set-by-set from real-time bar speed and exercise-specific MVT norms.
Vertical Jump Height Norms by Age, Sex & Sport
Compare your CMJ and squat jump height to normative data by age, sex, and sport, from youth athletes up to elite competitors, with benchmark tables.
Vertical Jump Norms in Korea: Normative Data by Age & Sport
See how your CMJ, SJ, and DJ jump height stacks up against Korean athletes by age, sex, and sport, plus the exact testing protocol used.
Velocity-Based Training for Jump Performance: Meta-Analysis Review
Across pooled RCTs, VBT protocols raised vertical jump height by an average of 7.2% over traditional percentage-based training.
Isometric Mid-Thigh Pull (IMTP): Testing Protocol, Norms & Applications
How to run the isometric mid-thigh pull correctly: bar height, ramp instructions, force-time variables to track, and normative data for comparison.
