The effect of gait speed and load carrying on the reliability of ground reaction forces

The effect of load distribution within military load carriage systems on the kinetics of human gait

“…In other words, longer stride lengths lead to greater force produced during the heel strike phase of the gait cycle. In response, a lower force minimum may be observed as active momentum has been generated in the initial phase of the gait cycle facilitating forward propulsion (Hsiang and Chang, 2002). This was proposed by the authors to be in accordance with the inverse pendulum model described by MacKinnon and Winter (1993).…”

“…To the author's knowledge only five studies have investigated some aspects of load distribution on GRF parameters, including just three papers in peer-reviewed journal (Kinoshita, 1985;Cooke, 2000a, Hsiang andChang, 2002), one military report (Harman et al, 2001) and one conference paper (Koulmann, 2006). These available studies have generally been restricted to between 4 and 6 load and carrying system combinations, with limited mechanisms put forward for the observed changes.…”

The influence of rifle carriage on the kinetics of human gait

“…Research into load carriage has shown that when load is carried around the hips (Birrell et al, 2007) and in a front pack (Hsiang and Chang, 2002) a greater impact peak is observed compared to a when load is carried in a backpack. This is due to a forward shift of the CoM, subsequently a greater proportion of the mass is over the striking foot at heel strike.…”

Modelling Gait Processes as a Combination of Sensory-motor and Cognitive Controls in an Attempt to Describe Accidents on the Level in Occupational Situations

“…Thus according to these authors "training in gait balance may help minimize slip and fall risks on ice for inexperienced outdoor workers and pedestrians". Other studies describe the incidence of biomechanical parameters on AoLs when carrying a load 22,23) , at various speeds 22) , for various ground inclinations and slipperiness 23,24) , while taking a turn on more or less slippery grounds 25) , when the operator is or not aware of the slipperiness of the ground 26) or when the operator has or not experienced the slippery ground. The most often studied interaction between human and environment is the shoe/slippery floor interaction when walking.…”
