Traction Dynamometer

Kinvent K-Pull

K-Pull sits in a line and reads tension. The sensor goes between an anchor point and a strap, handle or bar, and whatever the athlete pulls against it registers as tensile force. The K-Force app shows the pull as a live trace and keeps every attempt.

Loading through an anchor keeps the tester out of the load path, so the ceiling on the reading belongs to the athlete alone. That is what makes traction the right route for the powerful muscle groups: an isometric mid-thigh pull, a Nordic hamstring test, or a resisted hold at whatever angle the accessory kit lets you set up.

Why Traction

The Tester Steps Out Of The Line

A pulled measurement is bounded by the anchor and the athlete. Nobody has to brace against the effort for the number to be valid.

🔗
Operator-independent readings
With the sensor anchored, the figure reflects what the athlete produced against a fixed point. Two staff members running the same protocol are running the same test.
Anchored in line
🏋
Built for the big movers
Traction is how you get at hip, thigh and trunk musculature that produces more force than a handheld pad can take. Mid-thigh pull and hamstring work are the setups this sensor exists for.
IMTP and Nordic
📏
Any angle you can rig
The included accessory kit provides the attachment points, so the pull direction is whatever the anchor and the strap length allow. Positions repeat between sessions once the rig is written down.

Setting Up A Pull

Kinvent K-Pull
The Rig

Anchor, Strap, Sensor, Athlete

The sensor is placed in series between a fixed point and whatever the athlete holds or braces against. Change the anchor height or 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.

The Protocols

Mid-Thigh Pull, Nordic And Held Efforts

Kinvent list the isometric mid-thigh pull, the Nordic hamstring test and resisted strength work among the setups this sensor supports. Each produces a peak, and a timed effort adds the average force sustained, which is the figure that describes how long the output lasts.

  • Isometric mid-thigh pull
  • Nordic hamstring test
  • Resisted strength exercises
  • Average force across a timed effort
  • Strength ratios and side comparisons in the app

Questions

Frequently Asked Questions

Tensile force, meaning force in traction along the line the sensor sits in. It records the force peak of a maximal effort and the average strength maintained over an effort of a length you set.
The sensor anchors to a fixed point and nobody has to brace it by hand, which keeps the tester's own capacity out of the recorded value. Kinvent describe this as performing operator-independent measurements, and it is the practical reason to reach for traction on the large muscle groups.
Kinvent name the isometric mid-thigh pull, the Nordic hamstring test and resisted strength exercises. Anything else you can rig between an anchor and an athlete follows the same principle.
Kinvent describe the unit as engineered to withstand high forces but publish no capacity figure we can cite for this listing. The published specification covers 2.84 lbs and 10.83 x 5.19 x 6.69 in, so those are the numbers we state.
By where you anchor and how long the strap runs. The included accessory kit carries the attachment hardware, and once a rig is recorded it can be reproduced the same way at the next session.
Yes. Kinvent point to the average strength maintained for a given length of time as the indicator that describes endurance, and reading it against the peak from the same athlete describes how much output holds up across the effort.
Running paired positions on the same rig gives the app two values to hold together, whether that pair is a left and a right or two positions in a ratio. Keeping the rig identical between the two is what makes the comparison worth anything.
A Bluetooth link to the K-Force app on a phone or tablet, and no other equipment. The trace draws while the athlete is pulling, which is when a tester can tell a clean effort from a jerked one.
Clinic rooms, gym floors and pitch side, since it runs on battery and pairs to a handheld screen. The only fixed requirement is something solid to anchor against.
Strength and conditioning departments, sports medicine staff, rehabilitation clinics and research groups. The device supplies force data; the protocol and its interpretation belong to whoever is running the testing.
Where the athlete can out-push the person holding the device, traction is the better route, so hip and thigh work belongs on K-Pull. K-Push stays quicker for the many positions where a handheld pad is enough, and its published range is 90 kg at 0.1 kg. Plenty of clinics keep both and choose by muscle group.
