Spatio-temporal and kinetic parameters of walking in Sport (SP), Battle (BT) and Road March (RM) conditions, before (PRE) and after (POST) the Simulated Military Mission.

Values are presented as mean ± SD. ANOVA P values represent the main effects of time (T) and equipment (E), and the interaction effect (T×E). Post-hoc results are presented as:$SP = BT > RM;£SP#SP&SP = BT Wext: external mechanical work; Wext.TM: external mechanical work normalized to the total moving mass (TM), i.e. subject + equipment; Recovery: fraction of mechanical energy of the center of mass recovered via the inverted pendulum mechanism; Wint,dc: mechanical work done by one leg against the other leg during double contact; Wint,dc.TM: mechanical work done by one leg against the other leg during double contact normalized to TM; Locomotor efficiency: ratio of mechanical works (Wext and Wint,dc) to net CW.
