Traditional Posterior Load Carriage: Ergonomic Assessment and Intervention Efficacy
… MMH method called traditional posterior load carriage (PLC). Such load carriage is typically done without the use of an assistive device (e.g., backpack) in developing countries, and involves exposure to known risk factors for MSS such as heavy loads, non-neutral postures, and high levels …

A Quantification Of The Metabolic Demand Wrought By Explosive Ordinance Disposal Load Carriage
… concerning Explosive Ordinance Disposal (EOD) load carriage. These studies (Bach et al., 2017; Wu et al., 2022) have worked to quantify the ability of an operator to work while encumbered by EOD personal protective equipment (PPE), but have not evaluated possible sources of mitigation for the …

Body Mass Bias Mitigation for Females in Military Physical Readiness Testing through Load Carriage Implementation
… the bias for females through implementing load carriage during PRT events. A specified load is to be placed on women while performing the PRT and compared to a non-loaded control test. The results should show if the load carriage devised has a beneficial effect on current testing methods …

Understanding the effects of obesity and age on likelihood of tripping and subsequent balance recovery
… second study was two-fold. First, the effects of load carriage and ramp walking on the likelihood of tripping were investigated, followed by investigating the effects of age and obesity on the likelihood of tripping during load carriage and ramp walking. Again, likelihood of tripping was assessed …

Biomechanical adaptations of human gait due to external loads
… disease diagnosis, injury rehabilitation, and load determination. In this dissertation, the development of a model-based gait analysis technique to classify external loads is presented. Specifically, the effects of external loads on gait are quantified and these effects are then used to …

Development, Validation, and Testing of a Novel Ergonomic Backpack
… are one of the most common means for carrying loads but the loading mechanics that result from carrying heavy loads can have implications across the body. It has been suggested that loads in a BP should not excess 10-15% of the user’s body weight (BW) but that is not always feasible. The loads …

Analysis of fatigue in firefighters: foot clearances over stair edges and validation of a novel means for metabolic data collection
… validated in a stationary bicycling variable-workload assessment with two metabolic measurement devices (the portable Cosmed K4b2 unit and a limited portability metabolic cart unit). These conditions were: (1) the standard mask with the Cosmed K4b2, (2) modified SCBA facepiece with the Cosmed …

Human interaction & gait strategy with tightly-coupled lower-extremity systems
… Use cases span many fields, from military (e.g. load carriage assistance) to medicine (e.g. gait rehabilitation or restoration) and industry (e.g. injury prevention). Evaluating the human factors of human-exoskeleton interaction is an essential step towards operationalization. Unexplained …

The Hip and Lower Limb Movement Screen: Is it a valid tool to assess movement control in Royal Marines
… these were tested under military standards of load carriage as well as before and after a standard Royal Marine 8mile load carriage test known as the combat fitness test (CFT).<br/><br/>An custom-built Motion Analysis laboratory was built at 45 Commando Royal Marines and 32 Royal Marines were …

Design of a Novel Powered Exoskeleton for Human Jump Augmentation
… have typically focused on walking assistance, load carriage, and restoring lost functionality. This research presents the design of a novel powered exoskeleton for jumping assistance. The exoskeleton has a total mass of 24~kg (55~lb) and is capable of providing an additional 5000~N of launch …

Obstacle crossing behaviors in firefighters: effects of personal protective equipment and firefighter activity
… firefighting exercise protocols, as well as the carriage of a unilateral hose load when traversing the obstacle. Three simulated firefighting protocols were implemented, with each intended to replicate the environmental conditions and required workload of actual firefighting. To examine changes …

Design of a biomechanically synergistic exotendon suit
… evaluation of a lightweight, exotendon suit for load carriage. The suit is intended to be worn underneath the wearer's own clothes for use in a military setting, while reducing the energy expenditure of the wearer. A simple exotendon suit architecture was designed and implemented, consisting of …

Cutter, carriers and bucket brigades ...
… of fragment size, (b) the effect of load size on transport economics, (c) division of labour and task-partitioning. Grass-cutting ants, Atta vollenweideri, harvest grass fragments that serve as substrate for the cultivation of a symbiotic fungus. Foragers were observed to cut grass …

Effects of Pack Weight on Endurance of Long-distance Hikers
… trails, like the Appalachian Trail, load their backpacks down with gear that may exceed ideal limits on pack weight. Hikers pack clothing to deal with changing weather conditions, sleeping bags, tents, tarps, cooking gear, food, water and other accessories to compensate for the lack …

The effect of backpack load on trunk kinematics of imitated pathological gait: a case study
<p>Background: It is well documented that loaded backpacks affect the biomechanics of gait in both children and adults. Minimal information is available with regard to the effects of backpacks on the biomechanics of gait in individuals with clinical gait abnormalities, such as those seen in …

The Effects of a Uniformly Weighted Exercise Suit on Biomarkers of Bone Turnover in Response to Aerobic Exercise in Postmenopausal Women with Low Bone Density
… Weighted aerobic exercise, utilizing load carriage systems (LCS), is known to increase the gravitational forces impacting bone, creating a higher osteogenic stimulus than standard aerobic exercise. In response to the positive research on aerobic exercise with well-designed LCS, Dr. …

Gait Variability for Predicting Individual Performance in Military-Relevant Tasks
… was associated with faster learning rate. In a load carriage task, GV measures were more sensitive than average gait measures in discriminating between experience and load condition: experienced cadets exhibited reduced GV (in spatiotemporal measures and joint kinematics) and lower long-term …

Underactuated Exoskeletons for Lifting, Carrying, and Walking Assistance
… exoskeletons for walking assistance and heavy load carriage. The first exoskeleton can be used to provide assistance for walking in various applications such as industrial productivity, rehabilitation, and military or space training. We introduce a design for a lower body wearable device that …

Assessing the Effects of Exoskeletons on Physical Demands, Trip and Slip Risks, and User Perceptions in Manual Mining Tasks
… effects of BSEs on trip and slip risks during load carriage on different surface slopes. Using both BSEs differentially altered minimum foot clearance (MFC) and required coefficient of friction (RCoF). Rigid BSEs increased right foot MFC and RCoF, whereas the soft BSE largely preserved baseline …
