Does Inspiratory Muscle Training Improve Exercise Capacity with Thoracic Load Carriage?

Research Paper Title Inspiratory muscle training improves exercise capacity with thoracic load carriage. Background Thoracic load carriage (LC) exercise impairs exercise performance compared to unloaded exercise, partially due to impaired respiratory mechanics. The researchers investigated the effects of LC on exercise and diaphragmatic fatigue in a constant-load exercise task; and whether inspiratory muscle training (IMT)… Read More

Are there Gender Differences in Energy Expenditure During Walking With Backpack and Double-Pack Loads?

Research Paper Title Gender Differences in Energy Expenditure During Walking With Backpack and Double-Pack Loads. Background Studies have reported that energy expenditure during walking with double-pack loads is lower compared with backpack carriage. However, the effect of gender on energy expenditure while walking with these two load distribution systems has not been investigated. Therefore, the… Read More

What are the Cardio-respiratory Responses to Heavy Load Carriage over Complex Terrain?

Research Paper Title Cardiorespiratory responses to heavy military load carriage over complex terrain Background This study examined complex terrain march performance and cardiorespiratory responses when carrying different Soldier loads. Methods Nine active duty military personnel (age, 21 ± 3 yr; height, 1.72 ± 0.07 m; body mass (BM), 83.4 ± 12.9 kg) attended two test… Read More

Performance: Practice Makes Better

Research Paper Title Effect of Practice on Performance and Pacing Strategies During an Exercise Circuit Involving Load Carriage. Background Pacing is critical for athletic endeavours, and the strategies used by athletes are often modified after practice. The importance of practice when completing occupational assessments has been established; however, the effect of load carriage and discrete… Read More

Gait Biomechanics: Energy Harvesting Assault Pack vs Standard Assault Pack

Research Paper Title Spatiotemporal and kinematic changes in gait while carrying an energy harvesting assault pack system. Background Soldiers are fielded with a variety of equipment including battery powered electronic devices. An energy harvesting assault pack (EHAP) was developed to provide a power source to recharge batteries and reduce the quantity and load of extra… Read More

Discerning the Interaction Between Ambient Temperature, Hypoxia, & Load Carriage on Respiratory Muscle Fatigue

Research Paper Title Interaction Between Ambient Temperature, Hypoxia, and Load Carriage on Respiratory Muscle Fatigue. Background While respiratory muscle fatigue is present following load carriage activity at sea level, the effect of environmental conditions on respiratory strength while undertaking load carriage is unknown. Methods The effect of thoracic load carriage during walks (5.5 km) in… Read More
