Isometric strength testing provides high reliability and validity of assessment in functional positions. Our portable strength testing rig is ideal for measurement in the field.

Isometric strength testing is highly reliable as confounding variables such as technique, experience, velocity and acceleration are more controlled or eliminated compared to isotonic or isokinetic strength testing. Because there is no weight to control, accelerations or impacts the risk of injury is also considerably lower.

Innervations specifically designed the portable isometric strength testing rig for our C-Force Performance Platform to be very light weight at <2kg and collapse down into a compact 45cm x 10cm x 10 cm package.  We include a carbon fiber bar which is very strong but light and quickly and easily can be assembled or collapsed down for portability.

The height of the bar can be infinitely adjusted using the webbing straps and stainless steel cam buckle so that a wide range of positions can be tested:

  • mid-thigh pull
  • back squat
  • chest press
  • shoulder press
  • ankle plantar flexion
  • bent over row
  • upright row
  • deadlift
  • elbow flexor

When portability is not the primary concern we also offer the Fitness Technology IMTP Rack which is designed so that the barbell can be moved up or down by 3 cm increments. One or two spacer sheets of 1 cm thickness can then be placed on the force plate to provide adjustment of the barbell height to an accuracy of 1 cm. This is a VERY strong and stiff device and ideal for isometric strength testing in the weight room or laboratory. This isometric strength testing rack is designed specifically for the Fitness Technology 400s force platform or 400s+ force platform.
