Jump Analysis
Counter Movement Jump and Squat Jump protocols (CMJ & SJ): assess jump height and get indicators during the impulse phase on thrust, power, explosive force, RFD (Rate of Force Development) and Left / right distribution.
Drop Jump protocol (DJ): get jump height following a landing, force development during ground contact and the RSI (Reactive Strength Index).
Turnkey Protocols
Force / Velocity Spectrum Profile : measure optimal load for Maximal Power, a cutting edge test in biomechanics strength & conditioning. Guide your training towards one of these two antagonist components.
Dynamic Strength Index (DSI): get the ratio between an athlete’s ballistic peak force and their isometric peak force. This protocol includes isometric mid-thigh pull peak force (IMTP) and ballistic peak force during Counter Movement Jump (CMJ).
Unipodal CMJ / SJ: highlight Left/Right differences in Thrust, Force, Power, RDF, Jump Height.

K-invent accessories
Twin handle for muscle controller
The Twin Handle is an accessory that makes the KFORCE Muscle Controller easier to handle. The classic plug is removable, so you can switch it according to the needs of your evaluation. It is suitable for measures that require a stable and controlled two-handed grip. The use of a hand-held dynamometer has never been so comfortable.
Nordic test clamp for muscle controller
The Nordic Accessory is an accessory for the KFORCE Muscle Controller, it replaces the classic grip and allows the dynamometer to be fixed to a barbell for support on a stable plane. It fits very well for the Nordic Hamstrings Test as well as other evaluations or exercises requiring a dependent non-operator measurement.
Jump frame for plates
The Jump Frame is an accessory for the KFORCE Plates, it allows to stabilize the platforms and to obtain a larger surface at equal height to perform jumps in complete safety. It also allows you to adjust the distance between the plates to easily adapt it to the patient’s comfort. In addition, it ensures reproducibility of measurements under similar conditions. The Jump Frame is made of rigid foam. Lightweight and transportable, it will ensure the safety of your patients.
