Reconciling Laser/Doppler Sprint Speed With Timing Gates
Laser peak speed and timing-gate splits rarely match, and it is not a calibration error. The averaging math behind the gap, plus a field protocol to prove it.
Manual Stopwatch Sprint Timing Bias Correction: Aligning Hand-Timed Splits With Gate Data
Hand-timed sprints read about 0.2s fast. A field protocol for measuring your own timer's bias and correcting it to match gate-verified sprint times.
Why GPS Underreports Sprint Max Speed and How to Fix It
GPS max speed reads low for a reason: sampling rate, smoothing filters, and satellite lock. A control protocol to isolate which one is costing you km/h.
Horizontal Force-Velocity Sprint Testing With Motorized Resistance
Two sprinters can post the same 10m time for opposite reasons. Resisted sprints split F0, V0, and power to find which one is holding yours back.
Troubleshooting Inconsistent Sprint Trial Times: A Standardization Protocol
Sprint trial inconsistency usually is not the athlete. It is the start method, lead-in distance, or rest interval shifting between reps. Here is the fix.
Methods for Testing Maximal Sprint Speed Compared: Radar, Gates, GPS, and IMU
Radar, timing gates, GPS, and IMU rarely agree on the same sprint's top speed. Here's where each method's error comes from and which to trust for what.
Surfing Paddle Sprint Power Test: Measuring the Explosive Pre-Takeoff Burst on a Swim Bench
Surfing paddle sprint power isn't a 400m time trial pace, it's the last 10-second burst before takeoff. A swim-bench protocol for peak power and fade.
Timing Gate False Triggers: Fixing Sprint Times That Read Too Fast
An arm or trail leg clips the beam before the torso arrives and the gate logs a time that never happened. Here's the height and alignment fix that stops it.
Flying 10m Sprint Test: Protocol, Setup, and Benchmarks
A standing sprint blends acceleration with top speed. The flying 10m test isolates true max velocity, plus setup and benchmark times.
