| Description | Although carrying heavy loads impacts gait characteristics in military personnel, less studies have examined whether a gradually load increase affects foot parameters during quiet standing in the different population of intervention police officers. Therefore, the main purpose of the study was to examine differences in postural sway and ground reaction force characteristics during a quiet stance while carrying progressively heavier equipment. Ninety-six elite intervention male police officers were assessed under four conditions: (i) 'no load', (ii) 'a 5 kg load', (iii) 'a 25 kg load', and (iv) 'a 45 kg load'. Foot characteristics during standing were assessed with the Zebris pedobarographic pressure platform. Heavier loads increased 95% confidence ellipse area (p=.012, eta(2)=0.028), the center of pressure path length (p=.010, eta(2)=0.029) and average velocity (p=.011, eta(2)=0.029), and length of the minor (p<.001, eta(2)=0.040) and major axis (p=.004, eta(2)=0.035).
