Abstract

ObjectivesRugby union is a high intensity intermittent sport, typically analysed via set time periods or rolling average methods This study reports the demands of international rugby union via global positioning system (GPS) metrics expressed as mean ball in play (BiP), maximum BiP (max BiP), and wh...

An Opta sportscode timeline was integrated into the GPS software to split the data into BiP periods. Metres per min (m.min&#x2212;1), high metabolic load per min (HML), accelerations per min (Acc), high speed running per min (HSR), and collisions per min (Coll) were expressed relative to BiP periods and over the whole match ( &amp;#62; 60 min).ResultsWhole match metrics were significantly lower than all BiP metrics (p &amp;#60; 0.001). Mean and max BiP HML, (p &amp;#60; 0.01) and HSR (p &amp;#60; 0.05) were significantly higher for backs versus forwards, whereas Coll were significantly higher for forwards (p &amp;#60; 0.001). In plays lasting 61 s or greater, max BiP m.min&#x2212;1 were higher for backs. Max BiP m.min&#x2212;1, HML, HSR and Coll were all time dependant (p &amp;#60; 0.05) showing that both movement metrics and collision demands differ as length of play continues.ConclusionsThis study uses a novel method of accurately assessing the BiP demands of rugby union.
