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
