How to Test Bobsled Push-Start Power Without a Push Track: A 15m/30m Weighted Sled Protocol
No ice push track? Measure bobsled push-start power with a 15m/30m weighted sled protocol, individualized load ranges, and 2 cited studies.
Cricket Pace Bowling Run-Up Velocity Protocol: Timing the Final Approach Acceleration
Release speed alone can't show where bowling pace breaks down. Test the final 5m run-up acceleration zone instead — protocol, benchmarks, 2 cited studies.
Why a Low GPS Sample Rate Underestimates Acceleration: 10Hz vs 18Hz Explained and Fixed
Short cuts and stops finish in under a second - a 10Hz GPS unit can miss the actual peak. See why sample rate skews acceleration data, and how to fix it.
Sprint Velocity Plateau: How to Diagnose and Fix Stalled Speed
Stuck sprint times rarely mean the athlete needs more sprints. A field protocol to find whether force, technique, or stiffness is the actual limiter.
Sprint Split Time Benchmarks: 10m and 30m Norms by Sport and Level
A 0.05s gap at 10m separates D1 corners from walk-ons. See sprint split benchmarks by sport and level, plus how to test 10m and 30m correctly.
How to Improve Acceleration in Football: IMU-Driven 0-10m Sprint Power Protocol
This 12-week protocol uses IMU jump and barbell velocity data to find where power leaks and build 0-10m acceleration in football players.
How to Improve First-Step Quickness: An 8-Week Science-Based Acceleration Protocol
Elite athletes finish their first step in under 0.25 seconds. This validated 8-week, IMU-tracked protocol shows how to shave 0.05-0.10s off your time.
How to Improve Sprint Acceleration Strength in the Gym: Jumps, VBT, and 30m Power
80% of first-10m acceleration force comes from horizontal propulsion, 60% of it trainable in the gym. Trap-bar jumps and VBT lifted output 35% in 8 weeks.
How to Test Barbell Acceleration with an Attached IMU: Placement, Axis Calibration, and 7 Key Metrics
Velocity alone hides how a lift accelerates. This 7-step protocol covers IMU placement, axis calibration, and the metrics that reveal bar speed changes.
Track 100m Sprint Phase Training: Start, Accel, Max Speed, Decel
Specialized training for all four 100m sprint phases — block start mechanics, acceleration (0-30m), max speed (30-60m), and speed endurance through.
How to Run 10m/20m/30m Sprint Tests: Acceleration Assessment Standard
Get exact gate setup, split-time math, and norms for 7 sports and sexes, then match your 10m-20m-30m profile to one of 4 specific training fixes.
How to Improve Running Speed for Beginners
A 2019 study found beginners cut 40m sprint time by 5.4% in six weeks of structured drills, no weight room needed. Here's the stride-to-finish 8-week plan.
