A cross-sectional study of the effects of load carriage on running characteristics and tibial mechanical stress: implications for stress-fracture injuries in women
BACKGROUND Load carriage is associated with musculoskeletal injuries, such as stress fractures, during military basic combat training. By investigating the influence of load carriage during exercises on the kinematics and kinetics of the body and on the biomechanical responses of bones, such as the tibia, we can quantify the role of load carriage on bone health. METHODS We conducted a cross-s...
متن کاملThe effect of back pack load carriage on respiratory parameters in primary school student
Abstract: Background and Objectives: Most students use backpacks to carry their school supplies. Backpack carriage affects posture, physiological costs and physical performance. Limited literature concerning the effects of backpack load effect on pulmonary capacities of schoolchildren has been reported. The purpose of this study was to determine the effects of different backpack weights on pulm...
متن کاملErgonomic effects of load carriage on the upper and lower back on metabolic energy cost of walking.
We examined the effects of load carriage position on the energy cost of walking defined as the ratio of the 2-min steady-state oxygen consumption to the speed and economical speed. Fourteen healthy men walked on a treadmill at various speeds without and with load on the lower and upper back, which corresponded to 15% of their body mass. The energy cost of walking significantly decreased during ...
متن کاملEffects of Extreme-Duration Heavy Load Carriage on Neuromuscular Function and Locomotion: A Military-Based Study
UNLABELLED Trekking and military missions generally consist of carrying heavy loads for extreme durations. These factors have been separately shown to be sources of neuromuscular (NM) fatigue and locomotor alterations. However, the question of their combined effects remains unresolved, and addressing this issue required a representative context. PURPOSE The aim was to investigate the effects ...
متن کاملThe Energetics of Locomotion and Load Carriage in the Desert Harvester Ant Pogonomyrmex Rugosus
The locomotion and load carriage energetics of the southwestern American harvester ant, Pogonomyrmex rugosus, were quantified at several temperatures within their normal foraging temperature range using a voluntary locomotion regime (‘running tube respirometer’). In a metabolic rate (MR) versus running speed regression, the intercepts for the individual ants differed significantly, so data were...
