Are mechanics different between male and female runners with patellofemoral pain?
(http://journals.lww.com/acsm-msse/pages/default.aspx, 2012-11)INTRODUCTION: Patellofemoral pain (PFP) has often been attributed to abnormal hip and knee mechanics in females. To date, there have been few investigations of the hip and knee mechanics of males with PFP. The purpose of ... -
BIOMECHANICAL ALTERATIONS DURING THE SNATCH MOVEMENT AFTER REPEATED REPETITIONS
(East Carolina University, 2021-08-09)High Intensity Weightlifting (HIW) is a style of exercise that utilizes one of the two Olympic weightlifting movements, the snatch. The majority of HIW workouts are scored by time and have a goal to do the required repetitions ... -
BIOMECHANICAL DIFFERENCES IN LIFTERS WITH PRE-EXISTING INJURIES DURING THE SNATCH EXERCISE
(East Carolina University, 2022-05-04)Introduction: High intensity workouts are growing rapidly throughout the fitness industry. CrossFit and free weight workouts are becoming a popular standard throughout the exercise community. One of these exercises is the ... -
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 ... -
Comparison of Scaled vs. Ultrasound Based Musculoskeletal Models on Knee Muscle Moments During Single-Leg Squatting
(East Carolina University, 2012)Muscles produce force, resulting in moments about a joint, causing movement of the body. Muscle forces are estimated with a Hill-type model incorporating four parameters; optimal fiber length (OFL), tendon slack length, ... -
Control of Walking Speed in Young and Old Adults
(East Carolina University, 2012)Walking is a basic form of locomotion and walking velocity is a good predictor of human health, with faster velocities indicating better health. While faster walking velocities have been attributed to overall increases ... -
The Effect of a Hip Strengthening Program on Mechanics during Running and Single Leg Squatting
(http://www.jospt.org/doi/pdf/10.2519/jospt.2011.3470, 2011-07)STUDY DESIGN: Block randomized controlled trial. OBJECTIVES: To investigate whether a strengthening and movement education program, targeting the hip abductors and hip external rotators, alters hip mechanics during running ... -
Effect of Drop Jumping and Knee Valgus on Femoral Cartilage Thickness
(East Carolina University, 2023-05-03)Background: The incidence of anterior cruciate ligament (ACL) ruptures is 30-78 per 100,000 people a year. While the main treatment for an ACL rupture is surgery, only 61- 89% of athletes return to sports after surgery. ... -
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 ... -
The Effect of Load Placement on Lower Extremity Joint Biomechanics in Landing
(2014)Landing is a critical component to athletic performance. Many studies have investigated the effect that added mass has on landing biomechanics finding when load is added to the body during a landing task, an increase in ... -
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, ... -
Effects of a Six Week Gastrocnemius PNF Stretching Intervention on Structural Properties of Muscle and Neural Adaptations of Muscle in Young Women
(East Carolina University, 2018-05-18)Muscle injuries account for nearly one-third of sport medicine clinic visits in the United States (Woods et al, 2007) and amass financial burden on both athletes and their respective sports clubs. It is unclear whether ... -
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 Effects of Quadriceps Strengthening Exercise on Quadriceps Muscle Biomechanics During Locomotion in Adults with Knee Osteoarthritis
(East Carolina University, 2013)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 ... -
How do we accelerate while running?
(East Carolina University, 2015)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 ... -
IDENTIFYING THE EFFECTIVENESS OF AN ONLINE DANCE-SPECIFIC PROTOCOL ON ALIGNMENT AND MUSCLE ACTIVATION IN UNIVERSITY DANCE MAJORS
(East Carolina University, 2022-04-29)Sagittal pelvic alignment is a key component in a dancer’s ability to perform the physical tasks required of a dancer. To maintain and improve sagittal pelvic alignment and overall fitness, dancers must cross-train in ... -
Incorporating a visuomotor skill task with resistance training does not increase strength gains in healthy young adults
(East Carolina University, 2012)Resistance training causes well-documented adaptations in the nervous system and increases maximal voluntary force of healthy human skeletal muscle in the trained and also of the same muscle in untrained limb. It is also ... -
Increased Antagonist Coactivation-Related Hamstring Torque Reduces Maximal Knee Extension Torque in Healthy Old Adults
(East Carolina University, 2010)As humans age, the ability to produce maximal voluntary torque decreases due to muscle atrophy (sarcopenia) and it is also known that advancing age alters the neural control of voluntary movement. One manifestation of the ... -
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 ...
