This paper has very recently been published in MSSE and examines a new approach to the analysis of match physical data. It would be interesting to hear your thoughts on it.

Interesting paper.
To give an applied perspective we use the standard approach of reporting distance in different zones of velocity (like most football clubs do). Current commercially available match analysis systems to my knowledge do not claculate the magnitude of acceleration/deceleration during match play. I think this will be the next step for video analysis and estimation of the physical cost of any game is always going to be inaccurate without this type of data. Obviously there are other considerations that will add to the physical cost of a game such as back jockeying, side jockeying, jumping, competing, and jumping. Determining the frequency and magnitude of each of these actions is also imortant to fully understand the intensity of competition.
This also has an important crossover to monitoring training. GPS potentially offers the oppourtunity to calculate these 'utility' movements, therefore more accurate evaluations of intensity can be drawn, and therefore a more effective & efficient training programme can be devised.
