Abstract

PurposeWe compared a new locomotor-specific model to track the expenditure and reconstitution of work done above critical power (W´) and balance of W´ (W´BAL) by modelling flat over-ground power during exhaustive intermittent running.MethodNine male participants completed a ramp test, 3-min all-out...
