Physiological and Biomechanical Responses to Prolonged Heavy Load Carriage During Level Treadmill Walking in Females

Daniel E. Lidstone, Justin A. Stewart, Reed Gurchiek, Alan R. Needle, Herman van Werkhoven, and Jeffrey M. McBride

Heavy load carriage has been identified as a main contributing factor to the high incidence of overuse injuries in soldiers 1 , 2 and significant increases in peak or maximal vertical ground reaction force (VGRF MAX ) and maximal vertical loading rate (VLR MAX ). 3 , 4 Furthermore, previous

Tibiofemoral Load Magnitude and Distribution During Load Carriage

Blake W. Jones, John D. Willson, Paul DeVita, and Ryan D. Wedge

carry heavy loads. 9 – 12 Therefore, understanding knee joint contact force magnitudes and distributions during load carriage could provide insight into how the knee joint articular environment is altered by this activity. The tibiofemoral joint (TFJ) has medial and lateral compartments with different

Compromised Dynamic Postural Stability Under Increased Load Carriage Magnitudes

Alice D. LaGoy, Caleb Johnson, Katelyn F. Allison, Shawn D. Flanagan, Mita T. Lovalekar, Takashi Nagai, and Chris Connaboy

Operation Enduring Freedom and Operation Iraqi Freedom reflect 2 international military efforts where load carriage demands have challenged the capabilities and health of warfighters. 5 Load carriage–related injuries account for as many as one-quarter of preventable injuries with female warfighters

Nonlinear Analyses Distinguish Load Carriage Dynamics in Walking and Standing: A Systematic Review

Kolby J. Brink, Kari L. McKenzie, and Aaron D. Likens

workday. 2 Load carriage has received considerable attention in the literature on movement tasks such as sprints, vertical jumps, maneuverability tasks, agility, quiet standing, and walking. 3 – 10 Although there is considerable research on the basic kinematic and kinetic changes that occur during load

Center of Pressure, Vertical Ground Reaction Forces, and Neuromuscular Responses of Special-Forces Soldiers to 43-km Load Carriage in the Field

James Scales, Jamie M. O’Driscoll, Damian Coleman, Dimitrios Giannoglou, Ioannis Gkougkoulis, Ilias Ntontis, Chrisoula Zisopoulou, and Mathew Brown

Occupational load carriage is unique in military settings, as participants are required to carry absolute loads prescribed by the requirements of the task, as opposed to the soldier’s physical capacity. 1 Special operation forces soldiers have experience and training beyond their infantry trained

Stable and Unstable Load Carriage Effects on the Postural Control of Older Adults

Gregory S. Walsh, Daniel C. Low, and Marco Arkesteijn

Disturbances to the postural control system can come from numerous sources including physical perturbations, muscle fatigue, and load carriage. 1 – 3 It was demonstrated previously that a period of prolonged walking can lead to postural control alterations in older adults. 4 A potential

The Effect of Backpack Load Carriage on the Kinetics and Kinematics of Ankle and Knee Joints During Uphill Walking

Jinkyu Lee, Yong-Jin Yoon, and Choongsoo S. Shin

It is common for soldiers to carry a heavy backpack and a rifle over unpredictable terrain during military training and/or operations. The effects of load carriage on human locomotion have been reported, including decreased step length, increased step frequency, increased double support time, and

Load Carriage During Walking Increases Dynamic Stiffness at Distal Lower Limb Joints

Thiago R.T. Santos, Sergio T. Fonseca, Vanessa L. Araújo, Sangjun Lee, Fabricio Saucedo, Stephen Allen, Christopher Siviy, Thales R. Souza, Conor Walsh, and Kenneth G. Holt

Load carriage is a common task during recreational and occupational activities. 1 The mechanical stresses that the load imposes on the body cause the walking pattern to be stiffer than unloaded walking. 2 , 3 This pattern has been demonstrated by studies that calculated global (a model

Increases in Load Carriage Magnitude and Forced Marching Change Lower-Extremity Coordination in Physically Active, Recruit-Aged Women

Dennis E. Dever, Kellen T. Krajewski, Camille C. Johnson, Katelyn F. Allison, Nizam U. Ahamed, Mita Lovalekar, Qi Mi, Shawn D. Flanagan, William J. Anderst, and Chris Connaboy

Load carriage is a major component of training and operations in the military, with loads increasing substantially over the last decade. 1 With ∼30% of all lower-extremity musculoskeletal injuries occurring during load carriage conditioning at basic training (new recruits), load carriage tasks

Are Men and Women Equally Affected by Load Carriage While Landing? Analysis of Balance in Spanish Infantry Soldiers

Eva Orantes-Gonzalez and J. Heredia-Jimenez

 al., 2017 ). With respect to load carriage and balance, previous studies have analyzed the effects of different loads on landing biomechanics, which indicate the likelihood of lower body injuries and survivability in combat ( Dempsey et al., 2014 ; Palmer et al., 2013 ; Sell et al., 2010 ). In fact, part
