Qualitative analysis of team interaction in games by means of the load-performance-metamodel PerPot.

Observation of team behaviour in games shows rather inhomogeneous distributions of the levels of activity and effectiveness along the game. It is to expect, of course, that even for a high level team a phase of great effort is followed by a phase of reduced activities, while the opponent team is increasing its pressure. The result could be thought to be something like a rhythmic change, where the maximum activities of the one team correspond to the minimum ones of the other team.However, as we got from handball data that Martin Lames from the University of Ulm/Germany recorded last year (private correspondence), the correspondences can be much more difficult and varying: Lames measured the scoring effectiveness depending on the aggregated numbers of ball possessions that formed a non-linear transformation of the time axis. The results were diagrams where high and low performance intervals of both of the teams can alternate, follow and overlap each other or even can appear concurrently.Based on the interpr...
