PURPOSE Video match analysis is used for the assessment of physical performances of professional soccer players, particularly for the identification of "high intensities" considered as "high running speeds." However, accelerations are also essential elements setting metabolic loads, even when speed is low. We propose a more detailed assessment of soccer(More)
To estimate the energetics and biomechanics of accelerated/decelerated running on flat terrain based on its biomechanical similarity to constant speed running up/down an ‘equivalent slope’ dictated by the forward acceleration (a f). Time course of a f allows one to estimate: (1) energy cost of sprint running (C sr), from the known energy cost of(More)
