  • This release introduces two new measurables:
    • RPD or Rate of Power Development measures the ability to produce power rapidly during a dynamic muscle contraction. It is defined as the slope of the power-time curve during the acceleration phase and is measured in W/s. The Real Power Test now uses RPD to measure your capacity to generate explosive power.
    • TPP or Time to Peak Power measures the time required to reach the peak power during a dynamic muscle contraction and is measured in ms.
