Return to Sport Clearance Testing
DynaSled gives coaches objective data for one of the hardest decisions in sport: when an injured athlete is ready to return to full training and competition.
The problem with return to sport decisions is subjectivity. A coach watches an athlete sprint and judges by eye whether movement looks symmetrical. DynaSled removes the guesswork. Stride-by-stride bilateral force testing shows exactly how much force each leg is producing and whether the gap has closed enough to clear the athlete for return to sport.
The threshold commonly used in return to sport clearance protocols is a limb symmetry index (LSI) deficit of less than 10%. DynaSled shows this live in Syncro, stride by stride, during every session.
Post-ACL return to sprint
Track bilateral force output across the rehab timeline. Leg asymmetry testing at every session replaces subjective sprint observation with numbers you can act on.
Hamstring strain load progression
Monitor how each limb responds as resisted sprint load increases. Return to sport force testing confirms the injured leg is producing force at the required threshold before you progress.
Weekly asymmetry tracking during rehab
Run a short pull protocol each week. Longitudinal LSI data in Swift Labs shows the trend, not just the snapshot, so return to sport clearance decisions are backed by evidence.
Every detail. Engineered for sport.
DynaSensor™ built in
A precision load cell captures every push and pull at 100 Hz with 0.3 N resolution. Internal gyroscopes and accelerometers deliver accurate velocity measurement stride by stride. No external hardware. No cables to trip over.
Live to iPad. Always.
Bluetooth 5.2 LE streams force data to the Syncro app with less than 40 ms latency at up to 30 m range — from the turf, track, or court.
Built for the field
Powder-coated steel chassis rated to handle up to 75 kg of additional plates. 12-hour battery life, USB-C recharge in 3–4 hours. Built to live in a kit room and work on any surface.
Stride-by-stride insight
See peak force, impulse, and left–right asymmetry on-screen in real time, stride by stride. Export to Swift Labs for longitudinal trend analysis and team reporting.
Your data. From field
to insight.
DynaSled data collection is done with the Syncro iPad app — the same app that collects data from our G4 Timing Gates and EzeJump — full live data, stride-by-stride graphs, and session export. Your Swift Labs login unlocks it from day one.
A Year 1 Swift Labs Team subscription is billed with your hardware at checkout. It unlocks longitudinal reporting, team dashboards, asymmetry trend alerts, and AI-driven readiness flags — everything you need to turn raw numbers into training decisions.
