A comparison of measured and modelled energetics, estimated from global positioning systems (GPS) velocity / ROBERT OWEN

Swansea University Author: ROBERT OWEN

Abstract

Introduction:Traditionally in laboratory settings, indirect calorimetry and blood lactate B[La] analysis provide a criterion measure of bioenergetics, although it is not feasible within a multitude of competitive sports. Mathematical modelling provides a solution to estimate metabolic power during c...
