Sprint Times And Bar Speed

Kinvent K-Power Velocity Training Sensor

The Kinvent K-Power Velocity Training Sensor is a sprint and velocity sensor that measures distance, speed and power, using a pod on the athlete or the bar and a dock that tracks it. Sprint Mode returns top speed, average and peak power, and a force-velocity profile from the run itself. VBT Mode, for velocity based training, returns average bar speed, power and range of motion on every repetition, the numbers a coach sets the load by. Feedback comes back color-coded and audio-coded at once, so an athlete reads a repetition without leaving the bar. Everything for a sprint session, tripod and straps included, packs into its carry case.

The pod weighs 30 g and the dock 120 g, and the system works indoors and outdoors, with a range of up to 40 m in open field. Strength and conditioning staff, sports medicine teams and researchers use it for force-velocity profiling, research testing and rehab, where progressive loading gets a number attached. Speed training runs with resistance set against a measured number, and strength training is tracked repetition by repetition.

Inertial And Radio Tracking

How it works

The Kinvent app turns each run and each repetition into feedback the athlete can use mid-set.

IMU with ultra-wideband
An inertial measurement unit reads the motion of the pod itself, and ultra-wideband radio between the pod and the dock handles position. Both run wirelessly, in a gym or on grass.
IMU + UWB
High-rate capture
The pod captures movement at up to 800 Hz, and the ultra-wideband position updates at up to 100 Hz. The tracker reads acceleration up to 16 g.
Up to 100 Hz UWB
Sprint outputs
Top speed, average and peak power come back for every run, and the force-velocity profile is calculated in the app from the same run, with no spreadsheet. The sprint test adds Best 10 m and Best 10 yd metrics for comparing efforts.
Best 10 m and 10 yd
Color and audio feedback
Every repetition returns feedback on two channels together, one color-coded and one audio-coded. An athlete mid-set hears the outcome as well as sees it.

Sprints, Lifts And The Dock

How to use it

Kinvent K-Power, the dock unit standing on its tripod pole
Sprint

Sprint testing

For a sprint the dock sits on the tripod level with the pod, which rides on a strap around the athlete. It is ready in about 5 seconds with no cables, so a timed run drops into a session that was built around something else.

  • Pod holder on an 80 cm or 120 cm strap
  • Dock at about 93.5 to 110 cm for men or 82 to 102 cm for women
Sprint Mode Ready in 5 seconds

Velocity based training

Bar speed

The pod fixes to the bar with a small strap. On the bench press, range of motion per repetition shows whether depth held up as the set went on.

The two units

Between sessions up to five units stack on the dock to charge. The pod measures 49 x 20 mm against the dock's 64 x 43 mm.

Beside The Force Plates

How it compares

The K-Power tracks a body or a bar; the K-Force Plates, K-Deltas and 3D Deltas read force through the feet.

Getting K-Power Running

Frequently asked questions

It measures distance, speed and power, split across two modes: Sprint Mode for running work and VBT Mode for barbell work.
The pod moves with the athlete or the bar and carries an inertial measurement unit, and the dock holds a stationary unit that tracks it over ultra-wideband radio. The dock is part of every setup, on the floor or on the tripod.
The pod captures at up to 800 Hz, the ultra-wideband position is accurate to within 10 cm standing still, and static angle accuracy is 2 degrees, with acceleration read up to 16 g. It works indoors and outdoors, with an ultra-wideband range of up to 40 m in open field.
It shows time to 10 meters, peak velocity in m/s, peak power and mean power in W/kg, and mean acceleration in m/s2, with a Best 10 m figure for comparing runs. A session trend charts time to 10 meters run against run, and a speed trace marks the start and stop of each run. Every number lands in the app the moment the athlete crosses the finish, with no stopwatch.
A power analysis block carries the barbell weight and the max and average watts for every repetition. An interactive graph plots position in meters and speed in m/s against time, with a Show Phases toggle that shades eccentric and concentric separately, and an average propulsive velocity chart covers each set.
The app includes the sprint test with Best 10 m and Best 10 yd metrics, the 5-0-5 agility test broken into braking, change of direction and re-acceleration, the triple hop test for single-leg power and landing control, and group mode for testing several athletes in one session. The sprint test breaks a run into acceleration, peak speed and top speed, and the agility test shows which of its three phases an athlete is losing, which total time alone cannot. The triple hop test suits rehab, performance and return-to-sport work, where one limb is compared with the other.
The kit holds two K-Power units, the dock parts, a tripod pole for sprint work, two straps, a wall charger with a USB cable, the user manual and a carry case. A replacement tripod is sold on its own as the K-Power Tripod.
The pod runs about 20 hours as a tracker. A unit working as the station runs about 10 hours, or about 30 hours seated in the dock.
Yes. The K-Power works in the Kinvent app on a Starter, Premium or Excellence license, which renews automatically each year. The app comes from the Apple App Store and Google Play, and a K-Power run and a reading from another Kinvent sensor sit under the same athlete profile on phone or tablet. Group testing needs Premium or Excellence, and raw-data CSV export needs Excellence.
