Large Format Force Plates

Kinvent K-Deltas

K-Deltas are a pair of large-surface platforms Kinvent build for functional assessment and vertical jump analysis. Each plate reads force independently, so a two-footed task produces 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.

Kinvent publish a capacity of 2000 kg per platform, an accuracy figure of ±0.1%, a sampling rate of 1000 Hz / 2000 Hz (Full CoP) and 20 hours of continuous operation per charge. A rate in that band is what makes the short impulse phase of a jump readable as a curve rather than a single number at the end of it.

The Published Numbers

Speed, Capacity And Run Time

Every figure below is one Kinvent state for these platforms. Where they publish nothing, this page says nothing.

⚡

Sampling frequency

Kinvent quote 1000 Hz / 2000 Hz, with the 2000 Hz figure attached to full centre of pressure capture. Take-off in a countermovement jump is over in a fraction of a second, so the sample rate decides whether impulse and the shape of the force build survive into the analysis or get averaged away.

1000 / 2000 Hz

🏗️

Two tonnes per platform

A stated ceiling of 2000 kg on each plate leaves headroom above a loaded athlete landing from height, which is 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.

2000 kg

📐

Stated accuracy

Kinvent give ±0.1% for these platforms. It is the only accuracy statement attached to this product, and they do not publish the test conditions behind it, so read it as the manufacturer's own figure and nothing broader.

±0.1%

🔋

Twenty hours per charge

Continuous operation is quoted at 20 hours, which covers a full testing day for a squad without a mid-session charge. The plates connect over Bluetooth to the Kinvent app, so no cabling crosses the testing area between the plates and the tablet.

Jumping, Landing And The Gap Between Sides

Athlete jumping on Kinvent K-Deltas force plates

Vertical jumps

Height, and the phase that produced it

Kinvent name three jump protocols on these plates: the countermovement jump, the squat jump and the drop jump. Each one loads the athlete differently, and the plates record the whole trial rather than the result at the top, so a session shows impulse and the shape of the force build alongside the height. The force-velocity profile and DSI come out of the same testing.

Asymmetry

One platform per leg, one number per side

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 protocols run on one plate at a time, which is the format return-to-sport testing usually asks for. Kinvent list single-leg balance and single-leg jump work alongside the double-leg versions.

Isometric strength

The same platforms run the isometric side of a testing battery. Kinvent name the isometric mid-thigh pull, the ASH test and the McCall test, all of them measuring the ability to produce and hold maximal force while the split between limbs stays visible. Pair an isometric peak with a ballistic peak from the jump testing and DSI follows from the two.

Balance and posture

Standing still is also a measurement

Before anyone jumps, the plates record what a quiet stance looks like. Kinvent list postural stability and balance strategies under static conditions, centre of pressure position and velocity, and load distribution across the pair. The same surface carries functional movement work: squats, bridges, push-ups and sit-to-stand.

The set

A pair of plates, two surface sizes

K-Deltas work as a pair, and this listing carries two surface sizes. The standard platform is listed at 27.56" × 8.66" × 18.9" and 66.14 lbs; the XL option is listed at 36.61" × 8.27" × 22.83". A larger surface gives a wider margin for single-leg landings and loaded positions, which is the reason Kinvent build the surface area up in the first place.

Questions

Frequently Asked Questions

Force during movement and during quiet standing. Kinvent list load distribution, maximal force, impulse, the force-velocity profile, DSI, and take-off and landing quality among the key metrics, along with centre of pressure and CoP velocity for balance work and an asymmetry analysis reported as LSI.

Kinvent name the countermovement jump, the squat jump and the drop jump. Force-velocity profiling and DSI are listed alongside them, and landing control is recorded as part of the same trial rather than as a separate test.

Yes. Kinvent list the isometric mid-thigh pull (IMTP), the ASH test and the McCall test, described as measuring the ability to produce and maintain maximal force while imbalances between limbs stay visible. Relative strength is listed among the outputs.

Kinvent state 1000 Hz / 2000 Hz (Full CoP). We publish that string as written: the 2000 Hz figure is the one attached to full centre of pressure capture, and Kinvent do not explain which mode applies to which protocol.

2000 kg per platform. With one plate under each foot, a bilateral task has four tonnes of capacity beneath it, which is what allows loaded squats and drop landings on the same surface used for quiet standing.

Yes, ±0.1%. Kinvent do not publish the test conditions behind that figure, so read it as the manufacturer's own stated accuracy for the platform rather than an independently verified result.

Stand with one foot on each plate. Each platform records independently, so a bilateral task produces a separate force record per side and the app reports the Limb Symmetry Index between them. Single-leg protocols run on one plate on its own.

Two. The standard platform is listed at 27.56" × 8.66" × 18.9" and the XL at 36.61" × 8.27" × 22.83". The larger surface gives more margin on single-leg landings and loaded positions.

The specification gives 66.14 lbs for the standard and a second figure of 92.59 lbs. That second value is unlabelled in the listing, and by its position it corresponds to the XL. Confirm with us before you plan a transport case or a fixed install around it.

Over Bluetooth, to the Kinvent app. Kinvent quote 20 hours of continuous operation per charge, so a testing day for a full squad runs without stopping to charge.

Kinvent list real-time biofeedback, so balance, asymmetry, isometric and jump data appear as the trial happens. They also name a Smart Mode that automates testing and analysis and a Group Mode for sessions running several athletes or patients.

Yes. Kinvent name K-Push, K-Pull, K-Power, K-Myo and K-Move as a compatible ecosystem, all reporting into the Kinvent app, so a jump trial on the plates and a dynamometer or EMG measurement sit in the same profile.

Scale and scope of testing. The portable K-Force Plates are built around centre of pressure and weight distribution in standing work. K-Deltas carry a far larger surface, 2000 kg of capacity per plate and a published sampling rate, which is what jump, landing and isometric testing asks for.

Kinvent name physical therapists, sports performance professionals, physicians and researchers, working in rehabilitation centres, clinics, gyms, performance centres and field testing.

Kinvent publish CE marking, FDA registration, Health Canada registration, ISO 13485, ISO 9001:2015, ISO 27001:2022, HDS and HIPAA compliance across their platform. Those cover the company and its medical device and data handling. Kinvent publish no warranty term and no ingress protection rating for these plates, and we do not supply one on their behalf. Ask us and we will raise it with them.
