Objective benchmarks (i.e., target setting) cannot be determined for any test metric without the existence or creation of cohort-specific normative data sets. Standardized scores, namely Z-scores, are calculated as multiples of the standard deviation in relation to the mean [17,18].
WebReactive strength index (RSI) can be calculated by dividing the jump height by the ground contact time. disadvantages: The standard size boxes are not readily available, and may even need to be custom made. Results can be easily influenced by body position during take-off and landing.
