Hurdle Clearance Rhythm Test: Measuring Lead Leg Timing and Step Consistency Between Hurdles
Splits look clean but hurdle six tells another story. A CV protocol for inter-hurdle rhythm and lead leg timing that catches breakdown before it shows up.
Turf Toe Return to Sprinting: Push-Off Load Readiness Testing Before Full Speed
Pain-free jogging says nothing about big toe extension under sprint load. A push-off readiness protocol with research-backed cutoffs before max-velocity work.
Curve Sprint Test for Soccer: Protocol, Radius, and Deficit
A great 20m sprint time can still lose the arcing run to the byline. Get the penalty-arc curve sprint protocol, radius options, and deficit scoring.
Curve-Sprint Timing: Standardizing Radius and Entry Angle
Left curve 0.18s faster than right, every single week? A fixed-radius, fixed-entry-angle curve sprint protocol that stops your cones from lying to you.
Return-to-Sprint Force-Velocity Criteria After Hamstring Injury
Pain-free and a passed Nordic test don't prove sprint mechanics recovered. See the force-velocity protocol and cutoffs strength testing misses.
How to Measure Ground Contact Time with an IMU Sensor
Ground contact time separates elite sprinters from the rest by milliseconds. See the foot-sensor thresholds, sprint norms, and force-plate accuracy data.
