Large Format Force Plates

Kinvent K-Deltas

The Kinvent K-Deltas are a pair of large force plates for functional assessment and vertical jump analysis, with each plate reading force on its own. A two-footed jump therefore comes back as two force records, and the app reports the difference between sides. One set covers balance and postural stability, load distribution, isometric strength and jump testing. Each standard plate takes up to 2000 kg (4409 lb), and its sampling rate shows the short push before take-off as a full curve. Both sizes come as a pair and run about 20 hours on a charge.

Before anyone jumps, the plates record what a quiet stance looks like: postural stability under static conditions, center of pressure position and velocity, and load distribution across the pair. Squats, bridges, push-ups and sit-to-stand run on the same pair as functional movement tests. Rehabilitation centers, clinics, gyms, performance centers and field-testing teams all put them to work, from physical therapists and physicians to sports performance staff and researchers.

Built For Hard Landings

How it works

A drop landing hits hard and a jump is over fast, and each K-Deltas plate is built to read both.

Sampling rate
The standard plates sample at 1000 Hz or 2000 Hz with full center of pressure capture, and the XL plates at 4000 Hz. Take-off in a countermovement jump is over in a fraction of a second, and the sample rate decides whether impulse and the shape of the force build survive into the analysis or get averaged away.
Full CoP capture
Load capacity
The load ceiling on each plate, standard or XL, leaves headroom above a loaded athlete landing from height, the load case that matters on a drop jump or a rebound. It also covers barbell work standing on the plates for isometric and squat testing.
Drop jumps and barbells
Accuracy
Each plate, standard or XL, reads force to within 0.1%.
Standard or XL
Wireless link
The plates talk to the Kinvent app over Bluetooth with the tablet as far as 20 m away, so cables stay off the testing area. Each plate tops up over USB-C in about 2 hours and powers down by itself after 10 idle minutes.

On The Plates

How to use it

Vertical jumps

Jump testing

The countermovement jump, the squat jump and the drop jump all run on these plates, with the countermovement and squat jump protocols on Premium. Each one loads the athlete differently, and every repetition is recorded as a full trial.

  • Jump height, maximal force and impulse per repetition
  • Take-off and landing quality
CMJ Squat jump Drop jump

Asymmetry

Left against right

Because the two plates read independently, any bilateral task becomes a two-channel measurement and the app reports the Limb Symmetry Index between them. Single-leg balance and single-leg jump work run on one plate, alongside the double-leg versions.

  • Weight-bearing asymmetries identified in standing
  • Compensation strategies visible in the load split
  • Landing stability and movement control
LSI Single leg Return to sport

Plate size

Standard or XL

K-Deltas work as a pair, in two plate sizes. The standard plate is 547 x 368 mm and 44 mm high at 8.8 kg, and the K-Deltas XL plate is 810 x 470 mm and 49 mm high at 13.3 kg. A larger surface gives a wider margin for single-leg landings and loaded positions.

Where The K-Deltas Fit

How it compares

Jumps, drop landings and loaded lifts are what the K-Deltas are for. Balance and standing strength suit the lighter K-Force Plates, horizontal force needs the 3D Deltas, and sprints and bar speed go to the K-Power.

Frequently asked questions

They measure force during movement and during quiet standing. The key metrics are load distribution, maximal force, impulse, the force-velocity profile, DSI, and take-off and landing quality, along with center of pressure and CoP velocity for balance work and an asymmetry analysis reported as LSI.
Yes. The isometric mid-thigh pull (IMTP), the ASH test and the McCall test run on the plates, measuring the ability to produce and maintain maximal force while imbalances between limbs stay visible. The IMTP protocol comes with Premium, relative strength is among the outputs, and pairing an isometric peak with a ballistic peak from the jump testing gives the DSI.
Standard plates record at 1000 Hz or 2000 Hz and XL plates at 4000 Hz, and both sizes are accurate to within 0.1%.
Each standard plate takes 2000 kg (4409 lb) and weighs 8.8 kg (19 lb); each XL plate takes 2400 kg (5291 lb) and weighs 13.3 kg (29 lb).
Each set holds two K-Deltas plates in the size ordered, a USB-A power adapter, two USB-C to USB-A cables, quick start cards and the user manual.
They connect over Bluetooth to the Kinvent app on a phone or tablet. Each plate lasts about 20 hours between charges, long enough for a full squad's testing day.
It adds real-time biofeedback, so balance, asymmetry, isometric and jump data appear as the trial happens. Smart Mode automates testing and analysis, and Group Mode runs sessions for several athletes or patients on Premium or Excellence. The plates also work with the K-Push, K-Pull, K-Power, K-Myo and K-Move under one profile.
Yes. The plates work in the Kinvent app on a Starter, Premium or Excellence license, which renews automatically each year. K-Deltas activities, Group Mode and Smart Mode with several sensors need Premium or Excellence.
Kinvent covers it for one year from the date of purchase against defects in its electronics and mechanical components, with proof of purchase.
They differ in scale and scope of testing. The portable K-Force Plates are built around center of pressure and weight distribution in standing work. K-Deltas carry a far larger surface and a far higher load ceiling, which suits jump, landing and isometric testing.
