Our integration with VALD was built to bring a summary of the most important metrics collected with Force Decks to the Hylyght platform. These can then be used in combination with other tests and with specific benchmarks (e.g. based on the biological age for young athletes). It is not the goal to copy every single parameter, you can find this level of detail in the VALD hub. The following parameters per test were defined together with VALD staff.

The integration works well with several of our solutions: Talent identification & development, Rehab & prevention for athletes and Rehab for patients.

Jump tests

Abalakov - Counter Movement Jump with arms free

Assess explosive power and jump mechanics when the arms are used to assist the jump. Add one or both tests - depending on your interest in asymmetries:

Abalakov - CMJ arms free

• Jump Height in cm, based on impulse momentum
• RSI-modified, based on Jump height (impulse momentum) / Contraction time
• Peak power to BW in Watt/kg

Abalakov – CMJ arms free – Asymmetry (LSI)

• Eccentric Braking Impulse in Ns & Eccentric Braking Impulse LSI
• Concentric Impulse in Ns & Concentric Impulse LSI

Counter Movement Jump with hands on the hips

Focuses on lower body power, specifically isolating hip-driven movement during a counter movement jump. Add one or both tests - depending on your interest in asymmetries:

CMJ - hands on the hips

• RSI-modified, based on Jump height (impulse momentum) / Contraction time
• Peak power to BW in Watt/kg

CMJ - hands on the hips – Asymmetry (LSI)
