Sprint Times And Bar Speed

Kinvent K-Power Velocity Training Sensor

K-Power is a motion sensor that pairs an inertial measurement unit with ultra-wideband radio, and it records distance, speed and power. Kinvent give it two modes. Sprint Mode returns top speed, average and peak power, and split times at 10, 20 and 30 meters. VBT Mode returns average bar speed for each repetition, average and peak power, and the range of motion of the lift.

800 Hz is the capture rate Kinvent publish for this sensor. The unit is wireless, runs indoors and outdoors, and is listed at 2.2 lbs. Feedback comes back in two channels at once, color-coded and audio-coded, so an athlete reads a repetition without leaving the bar. A tripod stand accessory ships with the K-Power unit. Kinvent call it the first hybrid sprint and velocity based training sensor. The readers here are strength and conditioning staff, sports medicine teams and researchers.

Inside The Sensor

Two sensing technologies, one capture rate

Kinvent publish four things about how this unit works: what senses the movement, how fast it samples, what each mode reports, and how the result reaches the athlete. Those are the figures to read before it goes into a session plan.

📡
IMU with ultra-wideband
An inertial measurement unit reads the motion of the sensor itself. Ultra-wideband radio handles position. Kinvent put both in one wireless housing and run it in a gym or on grass.
IMU + UWB
⏱️
800 Hz capture
800 Hz is the figure Kinvent give for data capture. Sampling at that rate is what leaves a short acceleration phase and a single bar path with enough points to read.

Sprint Mode outputs
Top speed, average and peak power, and splits at 10, 20 and 30 meters. Kinvent state the split distances require no setup, and the force-velocity profile is calculated in the app from the same run.

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.

The run and the report, same screen

Kinvent's sprint view puts the six split and power fields at the top, a session trend for time to 10 meters beside them, and the speed trace underneath with the start, the 5 meter mark and the stop called out on the timeline. Nobody has to hold a stopwatch or re-key a number into a spreadsheet.

Per-repetition power and a bar path you can scrub

The squat view opens on a power analysis block: barbell weight at the top, then max and average watts for every repetition in the set beside the concentric averages for the whole set. Below it sits an interactive graph with position in meters and speed in meters per second on the same time axis, and a Show Phases toggle that shades eccentric and concentric separately. Average propulsive velocity gets its own chart under that, and the whole report exports out of the app.

Mode By Mode

One sensor, two jobs

Athlete sprinting with the Kinvent K-Power sensor
Sprint

Splits at 10, 20 and 30 meters

Sprint Mode reports top speed for the run, with average and peak power alongside it. Kinvent state the split distances need no setup, which is what lets a timed run drop into a session that was built around something else. The same run feeds the force-velocity profile the app calculates.

  • Top speed reported per run
  • Splits at 10, 20 and 30 meters, or 10 to 40 yards
  • Average and peak power for the effort
  • Force-velocity profile calculated in the app
Sprint Mode No setup

Bar speed, power and depth

VBT Mode reports the average speed of the bar for each repetition, which is the figure a coach reads to set load and to see how hard a lifter is driving. Average and peak power arrive with it, and range of motion records how far the lift travelled. The color and audio feedback lands while the set is still running.

  • Average bar speed per repetition
  • Average and peak power for the lift
  • Range of motion recorded on each repetition
  • Color-coded and audio-coded feedback in the set
VBT Mode Dual feedback

The same report off the bench

VBT Mode is not tied to the squat rack. Kinvent show K-Power running on the bench press, where average bar speed per repetition and range of motion answer the same question they answer under a squat bar: did the load move the way it was supposed to move, and did depth hold up as the set went on.

  • Bar speed and power on pressing movements
  • Range of motion recorded rep by rep
  • One sensor across the whole session

Test Protocols

Four protocols Kinvent run on K-Power

The app ships test templates, not just a raw capture screen. Each of these is a named protocol in Kinvent's own K-Power material.

🏁
Sprint test
Kinvent's sprint test breaks a run into acceleration, peak speed and top speed rather than reporting one total time. Best 10 m and Best 10 yd are the two metrics they added to the app for it.
Best 10 m · Best 10 yd
↩️
5-0-5 agility test
Braking, change of direction and re-acceleration are reported as separate phases. Total time alone does not say which of the three phases an athlete is losing.
Phase by phase
🦵
Triple hop test
Single-leg power, reactivity and landing control. Kinvent position this one for rehab, performance and return to sport work, where limb-to-limb comparison is the point.
Single leg
👥
Group mode
Built for testing or training several athletes or patients in one session, with the testing order and the data tracking organized in the app rather than on a clipboard.
Multi-athlete

Where It Gets Used

Five jobs Kinvent build K-Power for

💨
Speed training
Explosiveness and acceleration, with resistance controlled against a measured number instead of a feel.
🏋️
Strength training
Power and endurance work where progress is tracked repetition by repetition rather than session by session.
📐
Force-velocity profiling
The strength and speed balance, calculated in the app from a run so nobody has to build the curve by hand.
🔬
Research and testing
Repeatable captures for performance analysis and study work, with results exported from the report screen.
🩹
Rehab
Progressive loading with a number attached, which is what return-to-sport decisions get argued over.

The app

One app across every Kinvent sensor

K-Power pairs with the Kinvent app, the same application the rest of the range connects to. A sprint run, a squat set and a reading from a force plate or a dynamometer sit under one athlete profile, so the sensors do not each come with their own record to reconcile. The app runs on phone and tablet, and Kinvent publish it on both the Apple App Store and Google Play.

  • Real-time velocity, power output and movement quality
  • Phone and tablet, iOS and Android
  • Shared athlete profile across the Kinvent sensor range
  • Results exported from the report screen

Motion And EMG

Where K-Power sits in the range

Three Kinvent sensors work outside the force family. K-Power follows a body or a bar through space, K-Move measures the angle a joint reaches, and the K-Myo pair reads muscle activation at the skin.

Questions

Frequently Asked Questions

Distance, speed and power. Kinvent split those outputs across two modes: Sprint Mode for running work and VBT Mode for barbell work.
An inertial measurement unit and ultra-wideband radio, in one wireless unit. Kinvent describe the combination as the first hybrid sprint and velocity based training sensor.
800 Hz is the capture figure Kinvent publish for this device. It is the only rate they state, and we do not carry it across to any other sensor in the range.
10, 20 and 30 meters, which Kinvent also express as 10 to 40 yards. They state that these splits need no setup before a run. The sprint test report also breaks out time to 5 meters and time to 10 meters as separate fields.
Six fields plus two graphs. The fields are time to 5 meters, time to 10 meters, peak velocity in m/s, peak power in W/kg, mean power in W/kg and mean acceleration in m/s². The graphs are a session trend for time to 10 meters and a speed trace across the run with the start, the 5 meter mark and the stop marked on the timeline.
A power analysis block with the barbell weight and the max and average watts for every repetition, an interactive graph plotting 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. The report exports from that screen.
Kinvent publish four for K-Power: 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.
Yes. Kinvent list indoor and outdoor use for K-Power, and the ultra-wideband side of the sensor is what they credit for tracking outside a fixed installation.
Kinvent publish no accuracy or drift figure for K-Power, only the 800 Hz capture rate. Their own copy calls the tracking ultra-precise without attaching a number, so we leave that description off the page and give you the rate instead.
Yes. Kinvent state the profile appears in the app from the run itself, with no export step and no separate calculation.
Two kinds together: color-coded and audio-coded. Kinvent call this dual feedback, and it is what lets a lifter work from the result of the last repetition.
Yes, a tripod stand accessory is included with the K-Power unit. A replacement is sold on its own as the K-Power Tripod.
Kinvent list 11.81 in × 3.93 in × 7.87 in and 2.2 lbs. That figure covers the unit as supplied.
Kinvent's company and platform, not a performance claim about this sensor. They publish CE, FDA, Health Canada, ISO 13485, ISO 9001:2015, ISO 27001:2022, HDS and HIPAA across their range. The first four relate to medical device and quality management, the last four to information security and health data handling.
The Kinvent app, the same application every Kinvent sensor pairs with, available on the Apple App Store and Google Play and running on phone or tablet. A K-Power run and a reading from another sensor sit under the same athlete profile.
