Horizontal mechanical power approaches

Approaches and level of analysis of the physical demonstration of professional soccer players. Level 8 (part 2).

After analyze some (far from all ...) papers about different approaches proposed for the analysis of the horizontal mechanical power, I present you just some of them that could be applied for this sort of analysis.
In this sense, the fact of using the horizontal mechanical power approach represents (under my view) another step forward for analyzing the conditional demonstration of soccer players (and also other sports ...) during games and trainings.

Using one or another approach should facilitate the analysis and interpretation of the mechanical load related not only with speed, but specially with accelerations and decelerations, in which their relationship with the velocity alters the mechanical power experienced by the player.
An acceleration performed with a velocity of 5 km/h represent a different load than other performed with a velocity of 15 km/h, and the same is valid for decelerations. So not only the absolute value is important, but also the velocity associated with it.

Some of the approaches have been used for their application with soccer players, others no. Lets see their essential differences.

Hope you find it interesting.
