Sports science, distilled.
Summaries and analysis of key research papers in sports science, velocity-based training, and performance measurement.
Sleep and Athletic Performance: What the Research Actually Quantifies
Sleep restriction cuts sprint speed 3% and strength up to 11%; extending sleep to 10 hours lifts free-throw accuracy 9%. Both directions, compared.
Velocity-Based Training Research Review: Current Evidence
From load-velocity profiles to autoregulation, this review breaks down VBT's research base into practical takeaways coaches can apply this week.
Velocity Loss and Fatigue: Research on Optimal Cutoffs
What does research say about velocity loss thresholds? Evidence on fatigue markers at each cutoff, and how to set stop-set criteria for your goal.
Warm-Up and Performance: What the Research Actually Shows
A PAP-optimized warm-up beat passive rest by 3.6% in CMJ height and 1.8% in sprint speed. Here's the exact protocol structure the research points to.
Youth Resistance Training Safety: Research Evidence
What does the research actually say about resistance training safety for young athletes? Injury rates, growth plate risk, and evidence-based load.
Sleep and Athletic Performance: How Sleep Deprivation Impacts Power, Speed & Recovery
Competitive athletes sleep 6.5-7 hours a night, well under the 8-10 hours research says peak performance needs. Here's the cost, and the fix.
ACL Injury Prevention Screening: Research on Risk Assessment and Neuromuscular Testing
Which ACL screening tests actually predict risk? A review of jump-landing, neuromuscular, and movement-screen protocols and where each one falls short.
CMJ Monitoring for Athlete Readiness: Research on Countermovement Jump as a Fatigue and...
A lower jump isn't always fatigue, but research points to thresholds that matter. Here's how CMJ flags overreaching and guides same-day training calls.
Force-Velocity Profiling Research: Understanding the Science Behind Individualized Power Training
Two athletes with identical vertical jumps can need opposite training plans. Force-velocity profiling finds the real limiter behind each one.
Plyometric Training Meta-Analysis: What the Research Says About Jump Training Effectiveness
The largest plyometric meta-analysis to date pools 286 studies and 8,619 athletes to quantify effects on jump height, sprint speed, RSI, and injury risk.
Force-Velocity Profile: The Complete Guide for Athletes and Coaches
Most athletes are force-dominant or velocity-dominant without knowing it. Here's how to build your F-V profile with Samozino's method and fix the gap.
Reactive Strength Index (RSI) Explained: What It Is and Why It Matters
RSI is jump height divided by ground contact time, but a good score varies by sport and level. Here is how to test it correctly and pick drills that help.
