Overview Measurement Types

The following overview shows a summary of the test types and outcome parameters of the measurement types supported by Leonardo Mechanography. The Leonardo Mechanography Research edition (RES) includes all measurement types of the Standard Edition 8STD).

     Standard Edition (STD)

The following measurement types are supported by Leonardo Mechanography STD:

  1. s2LJ: single 2 Leg Jump: Jump for maximum height (counter movement jump)

      Type: Performance (power test).

      Field of application: Basic performance (power) test.

      Outcome parameters: Force, acceleration, power, kinetic energy, potential energy, jumping height, counter movement, mass, L/R differences (force, power), Esslinger Fitness Index (E.F.I.), efficiency of movement.

Variations:

 s2LJ (single two-legged jump): free jump for maximum jumping height without any restriction (any counter movement and free arm movement allowed). Goal: intuitive and therefore highly reproducible movement pattern.

 CMJ (Counter Movement Jump): similar to s2LJ without arm movement (hands rest on the hip during the complete movement)

 CMJ.1L L/R (Counter Movement Jump One Legged Left/Right): similar to CMJ, but the actual counter movement and jump is performed on one leg only, also without arm movement (hands rest on the hip during the complete movement). Start and end position similar to s2LJ standing upright on both legs, after the start of the measurement the counter movement and the jump is performed on one leg only.

 SJ.90 (Squat Jump 90°): Squat-Jump with a start position at 90° knee angle, fore-foot and heel with ground contact, also without arm movement (hands rest on the hip during the complete movement). Start and end position similar to s2LJ standing upright on both legs, after the start the person moved to a squatting position with 90° knee angel, waits for 2 seconds and then performs a jump for maximum height from this position.
