NEURAL MECHANISMS CONTRIBUTE TO THE AGE RELATED INCREASE IN METABOLIC COST OF GAIT
(East Carolina University, 2010)
Aging is associated with biomechanical and physiological changes in several organ systems, including neural changes of voluntary movement. One manifestation of age-related changes in neural control of gait is the increased ...
POSITIVE VS. NEGATIVE MUSCLE WORK OF NON-LEVEL WALKING IN LEAN AND OBESE ADULTS.
(East Carolina University, 2010)
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 ...
A Comparison of Lean and Obese Gait Characteristics of Children and Adults During Level Walking
(East Carolina University, 2010)
Increased body mass affects gait kinematics and kinetics in adults. It is however unknown if increased body mass produces similar adaptations in children and adults. The duration of obesity in children is shorter than ...
STRIDE LENGTH MANIPULATION IN YOUNG AND OLD ADULTS DURING LEVEL WALKING
(East Carolina University, 2010)
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 ...
Influence of Thigh Muscle Forces on Anterior Cruciate Ligament Forces during Single-Leg Landing from Three Different Heights
(East Carolina University, 2010)
Over 200,000 anterior cruciate ligament (ACL) injuries occur every year amounting to billions of dollars being spent on the ACL annually. While the quadriceps muscle produces an anterior shear force on the tibia that ...
The Effect of Plantarflexor Strength Training on Gait Biomechanics in Healthy Old Adults
(East Carolina University, 2013)
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, ...
The Effect of Eccentric Hamstring Strength Training on Muscle Function
(East Carolina University, 2015)
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 ...
Effects Of Extracellular Matrix Stiffness On Muscle Fiber Mechanotransduction Signaling In Aged Rats
(East Carolina University, 2015)
The loss of muscle mass with age, termed sarcopenia, is a common problem among the over 60 years-old population. Resistance training is often prescribed as treatment, but older adults have shown a reduced response to ...
THE VARIATION IN STRENGTH DECREMENT OF LOWER EXTREMITY MUSCLE GROUPS AND BIOMECHANICAL PLASTICITY IN OLDER ADULTS
(East Carolina University, 2019-08-13)
Age-associated biomechanical plasticity (BP) has been established as the distal to proximal shift of joint mechanical output in old adults while walking. The cause of BP is still unknown, but changes in muscle strength of ...
