To establish the reliability of various measures obtained during single and repeated countermovement jump (CMJ) performance in an elite athlete population.


Two studies, each involving 15 elite Australian Rules Football (ARF) players were conducted where subjects performed two days, separated by one week, of AM and PM trials of either a single (CMJ1) or 5 repeated CMJ (CMJ5). Each trial was conducted on a portable force-plate. The intraday, interday, and overall typical error (TE) and coefficient of variation (CV%) were calculated for numerous variables in each jump type.


A number of CMJ1 and CMJ5 variables displayed high intraday, interday, and overall reliability. In the CMJ1 condition, mean force (CV 1.08%) was the most reliable variable. In the CMJ5, fight time and relative mean force displayed the highest repeatability with CV of 1.88% and 1.57% respectively. CMJ1Mean force was the only variable with an overall TE < smallest worthwhile change (SWC).


Selected variables obtained during CMJ1 and CMJ5 performance can be used to assess the impact of both acute and chronic training and competition. Variables derived from the CMJ5 may respond differently than their CMJ1 counterparts and should provide insights into differential mechanisms of response and adaptation.

The participants completed a maximal-effort one-repetition parallel back squat, standing broad jump and standing vertical jump, and pull-ups and dips to failure. The testing protocols described in detail by the National Strength and Conditioning

The authors hypothesized that (1) all RST groups will experience improvements in sprint and COD performance, and they will also likely obtain enhancements in horizontal and vertical jump performance, and (2) the groups that performed RST with horizontally

The players were instructed to use a preliminary movement by rapidly flexing the knee, before launching the body vertically
