When a muscle produces voluntary force, muscles on the opposite side of the joint, the antagonists, are also activated. While coactivation of the knee flexors during knee extension is presumed to increase joint stability ...

When walking on non-level surfaces at a constant speed, an individual's total mechanical energy will increase when walking up an incline, and will decrease an equal amount going down a decline. Total muscle work performed ...

Physiological and neurological changes with healthy aging cause old adults to alter biomechanical gait strategies. Mechanical plasticity is an ambulatory strategy in which old adults rely on proximal musculature in ...

The high prevalence of hamstring strain injury in sports, coupled with detrimental performance and financial effects of hamstring injuries, stress the necessity to implement an intervention capable of minimizing hamstring ...

Locomotion is an important and inherent part of daily life and is integral in maintaining an independent lifestyle, especially in older adults whose functional capacity has declined. Physiological changes with aging, ...

Walking gait is one of the basic components of human movements. With the rising obesity epidemic and implied health complications, it is pertinent to examine the relationship between body mass index and the joint torques ...

Running biomechanics are well established in terms of lower extremity joint kinetics as is the direct relationship between these variables and running speed. Many studies have investigated the differences in these variables ...

Knee Osteoarthritis (OA) is a disease characterized by knee joint deterioration and pain, while also being associated with altered knee joint mechanics and quadriceps strength deficits. Research investigating the effects ...
