Traction Dynamometer

Kinvent K-Pull

K-Pull is a wireless tensile dynamometer. The sensor sits in line between an anchor point and a strap, handle or band, and whatever the athlete pulls against it registers as tensile force. Kinvent build it around high-precision sensors that record isometric and dynamic force production, and the reading lands in the Kinvent app as it happens.

Loading through an anchor keeps the tester out of the load path. Nobody has to brace the device by hand, so the ceiling on the number belongs to the athlete rather than to whoever is holding the sensor. That is why traction is the route to the hip, thigh and trunk muscles that out-produce a handheld pad, and why Kinvent list the isometric mid-thigh pull and the Nordic hamstring test among the setups this unit was built for.

The Technology

Four Things Kinvent Built Into It

A pulled measurement is bounded by the anchor and the athlete. These are the four capabilities Kinvent publish for the sensor, and what each one changes about a testing session.

🎯
High-precision force measurement
Kinvent specify high-precision sensors that record isometric and dynamic force production. Isometric covers the held effort with no joint movement; dynamic covers force through a moving rep. One sensor reports both, so a max test and a loaded exercise go into the same file.
Isometric and dynamic
📡
Compact, portable and wireless
Bluetooth to a phone or tablet, 2.84 lbs in the hand, nothing to plug in. Kinvent point it at clinical, gym and on-field use, which in practice means the working kit is the sensor, the straps and a screen you already carry.

🔗
Built for high load
Kinvent describe the unit as engineered to withstand high forces. They publish no capacity figure, so we quote none, but the reason it matters is repeatability: a sensor that flexes under a heavy mid-thigh pull gives you a different number in week six than it gave in week one.
No capacity figure published
🏋️
Versatile pull-based testing
The named tests are the isometric mid-thigh pull, the Nordic hamstring test and resisted strength exercises. Move the anchor or change the strap length and the same device covers a different joint angle, which is how one unit serves lower limb, trunk and upper body positions.

Closer Look

Setting Up A Pull

Kinvent K-Pull sensor anchored in line during a strength test
The Rig

Anchor, Strap, Sensor, Athlete

The sensor goes in series between a fixed point and whatever the athlete holds or braces against, and it reads the tension in that line. Because the load path runs anchor to athlete, the person running the test never becomes the limiting factor, and two staff members working the same protocol are running the same test.

  • Tensile force read along the line of pull
  • Angle set by anchor position and strap length
  • Reading unaffected by the tester's own strength
  • Same rig reproduces at the next session
  • Sensor weighs 2.84 lbs at 10.83 x 5.19 x 6.69 in

The Protocols

Mid-Thigh Pull, Nordic And Resisted Work

Kinvent name three families of test: the isometric mid-thigh pull, the Nordic hamstring test and resisted strength exercises. The first two produce a peak from a maximal effort. The third is where dynamic force recording earns its place, because the athlete is moving under load rather than holding a position.

  • Isometric mid-thigh pull
  • Nordic hamstring test
  • Resisted strength exercises
  • Force peak from a maximal attempt
  • Average force across an effort you time

The Accessories

Straps, Bands And A Fixed Point

Kinvent show the sensor run from an ankle strap to an elastic resistance band anchored on a wall ladder, with the athlete prone on a treatment table for a leg curl assessment. That is the whole idea in one picture: the hardware between the athlete and the anchor decides which joint you are testing, and the sensor reads the line regardless.

  • Ankle strap to elastic band to wall ladder, as Kinvent set it up
  • Treatment table, gym rig or squat cage all serve as the fixed point
  • Band length and anchor height change the joint angle under test
  • Write the rig down once and the retest repeats it

The App

Objective Measurement, Live Feedback

Every Kinvent dynamometer talks to the same app, and Kinvent describe what it gives you as objective measurement, real-time feedback and progress tracking. Feedback that arrives while the athlete is still pulling is the part that changes a session, because a tester can tell a clean build from a jerked one before the attempt is banked.

  • Readings appear live during the effort
  • Attempts stored against the athlete for later comparison
  • Shared app across the Kinvent dynamometer range
  • Runs on a phone or tablet over Bluetooth

Questions

Frequently Asked Questions

Tensile force, meaning force in traction along the line the sensor sits in. Kinvent describe it as a wireless tensile dynamometer with high-precision sensors that record both isometric and dynamic force production.
Because with the sensor anchored, nobody has to brace it by hand, so the tester's own capacity never caps the reading. On the hip, thigh and trunk muscles that can out-push the person holding the device, that is the difference between a valid number and a number that describes the tester.
Kinvent name the isometric mid-thigh pull, the Nordic hamstring test and resisted strength exercises. Anything else you can rig between a fixed point and an athlete works on the same principle, since the sensor reads whatever tension runs through the line.
No. Kinvent state the unit is engineered to withstand high forces but publish no capacity figure, so we quote none. The published specification covers 2.84 lbs of sensor weight and 10.83 x 5.19 x 6.69 in, which are the numbers we will stand behind on this listing.
Kinvent publish no accuracy or resolution figure for K-Pull. What they do publish is the sensor description, high-precision sensors recording isometric and dynamic force production, and the certifications behind the company, including ISO 13485 for medical device quality management. If you need a tolerance figure for a research protocol, ask us and we will take it to Kinvent rather than guess at one.
Kinvent do not publish a runtime for this sensor. The page confirms it is wireless with Bluetooth connectivity and no mains connection during use, which is why it works on field and on a gym floor, but we have no hour figure to give you.
By where you anchor and how long the strap or band runs. Kinvent's own example puts an ankle strap on a prone athlete, runs it to an elastic resistance band fixed to a wall ladder, and reads the leg curl through the sensor in between. Record the anchor point and the strap length and the retest reproduces the same position.
Yes. Alongside the force peak from a maximal attempt, the app reports the average strength maintained across an effort of a length you set. Reading that average against the same athlete's peak is what tells you how much of their output survives the duration.
Run the paired positions on the same rig and the app holds both values against the athlete, whether the pair is a left and a right or two positions in a ratio. Keeping the anchor, strap length and body position identical between the two attempts is what makes the comparison worth reading.
A phone or tablet running the Kinvent app, and something solid to anchor against. The link is Bluetooth and the app gives what Kinvent call objective measurement, real-time feedback and progress tracking, so the reading is on screen while the athlete is still pulling.
Kinvent list clinical, gym and on-field use. At 2.84 lbs with a wireless link and no power lead, the practical limit is not the device, it is whether the room gives you a fixed point strong enough to anchor to.
Kinvent name physical therapists, sports performance professionals, physicians, researchers, coaches and trainers. The sensor supplies force data; the protocol and its interpretation stay with whoever runs the testing.
Where the athlete can out-produce the person holding the device, traction is the better route, so hip and thigh work belongs on K-Pull. K-Push stays faster for the many positions where a handheld sensor is enough, and plenty of clinics keep both and pick by muscle group. Both report into the same app, so the results sit in one athlete profile either way.
Kinvent display CE, FDA, Health Canada, ISO 13485, ISO 9001:2015, ISO 27001:2022, HDS and HIPAA on this product page. Those cover the company, its medical device quality system and how it handles health data. None of them is a performance claim about the force reading itself.
