Measure power and performance with this jump metric.
Countermovement jump height is a commonly used performance measure as it reflects quad strength and power production. In sports like volleyball and basketball, jumping higher can be an advantage, so jump height is often used in recruiting and performance tracking. Changes in jump height can be an indicator for neuromuscular fatigue.
Examples of how to use Plantiga’s Countermovement Jump Height Measure:
Jump Height as a direct performance measure - Jump height thresholds are crucial for determining baseline abilities of athletes in sports that include a lot of jumping. For example, jump height may be an important factor in choosing a level of play (ex. NCAA division I, II, III) and recruiting. Note that vertical jump in volleyball is typically shown as a spike or block touch, reflecting how high an athlete can reach with their jump. Jump height can be calculated from this measure by subtracting standing reach height.

Jump Height as an indirect performance measure - Jump height is associated with lower body power production and has been shown to correlate with 30m sprint times and 1RM back squat.

How to interpret Plantiga’s Countermovement Jump Height Measure:
Jump height will vary depending on the population tested, so countermovement jump height thresholds for the average adult are shown below. Note, however, that these normative values are for a CMJ with arm swing. No normative values were available for a CMJ with hand on hips, but the use of arm swing increases jump height by approximately 10%
