DynaSled

Force plates only see
half the picture.

Traditional force plates measure vertical ground reaction force. But sprinting, tackling, and change of direction are driven by horizontal force — the component that actually moves an athlete forward.

DynaSled captures what they miss: stride-by-stride horizontal force, velocity, and left–right asymmetry — all on the surface where performance actually happens.

Push & Pull

Not all sled work is equal.

Push drills

When an athlete pushes a loaded sled, the closed loop system between sled, arms, torso and legs creates a preload on the push-bar. This force preloads the DynaSensor with a percentage of body weight, which results in lower fidelity in the data you would see in a tethered pull drill. The result is smaller force excursions and a compressed dynamic range — the sensor sees less of what you're actually interested in.

DynaSled can record push sessions, but it is not designed for heavy push sled work. If maximum load is your goal, a standard sled will serve you better.

Push drill force trace — note the elevated baseline caused by body-weight preload on the DynaSensor

Push drill — sustained baseline above zero due to closed-loop preload. Peak: 216 N · Avg: 105 N

Pull drills — where DynaSled excels

Pull drills remove the preload problem entirely. Without body weight bearing down on the sled, the sensor captures the full horizontal force profile — greater dynamic range, sharper impulse peaks, and far more pronounced left–right asymmetry.

This is where DynaSled delivers its most actionable data: asymmetry that would be invisible on a force plate, and a force–velocity profile that reflects exactly what the athlete produces stride by stride. The image below is a composite of left and right leg forces and how the sled friction and inertia reacts against the athlete.

Why DynaSled

Every detail. Engineered for sport.

Sensor

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.

Connectivity

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.

Durability

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.
