Reliability Of A Multisegment Foot Model In Shod Running, Austin Coupe
UNLV Theses, Dissertations, Professional Papers, and Capstones
The purpose of this study was to determine kinematic and marker placement reliability of the Leardini multisegment foot model (LMFM) for tracking foot kinematics during barefoot and shod running without alteration of footwear. Eleven participants, five males (25.6±5 yrs, 73±15.8 kg, 1.75±0.05m) and six females (22.5±2.9 yrs, 66.6±7.2 kg, 1.71±0.05 m) granted institutionally approved written consent to participate. Three-dimensional motion capture (10 Vicon T40-S cameras) was used to capture kinematic data at 200Hz. Kinetic data was captured with an in-ground force platform (Kistler Instruments AG, Switzerland Model 9281B 60x40cm, 2000Hz). Participants were instructed to run at 3.5m/s ±5%. Velocity was …
Changes In Sprint Kinetics Or Kinematics Following Static Or Dynamic Stretching, Kristyne Bartel
Changes In Sprint Kinetics Or Kinematics Following Static Or Dynamic Stretching, Kristyne Bartel
UNLV Theses, Dissertations, Professional Papers, and Capstones
The purpose of this study was to determine the effects of static or dynamic stretching on hip kinematics and kinetics during intermittent sprinting. To achieve this aim, intermittent sprint athletes were asked to complete either a static or dynamic stretch, followed by a repeated-sprint protocol. Hip joint kinematics and performance measures were evaluated during the sprint, including changes that occurred in these variables over the course of the sprint protocol. In addition, hip flexion torque was measured with an isokinetic dynamometer. Ten male (age = 25±2.3 years, 175±3.2 cm, 76.2±2.7 kg) and female (age = 20±1 years, 166±1.3 cm, 60±1.1 …
Comparison Of Muscle Latencies For Diabetic Neuropathy Patients Versus Healthy Controls During A Perturbed Balance Task, Kyle Mefferd
Comparison Of Muscle Latencies For Diabetic Neuropathy Patients Versus Healthy Controls During A Perturbed Balance Task, Kyle Mefferd
UNLV Theses, Dissertations, Professional Papers, and Capstones
The purpose of this study was to compare muscle latencies for patients diagnosed with diabetic neuropathy versus healthy controls during a perturbed balance task, with a secondary purpose to distinguish postural control strategies the groups used based on the muscle latencies. Five participants diagnosed with diabetic neuropathy (DN; 4 male, 99.7 ± 7.95 kg, 176 ± 9.58 cm, 46.6 ± 16.55 years) and 5 healthy control (HC; 4 male, 100.36 ± 12.61 kg, 173.76 ± 9.66 cm, 47 ± 13.42 years) participants were recruited. Participants granted institutionally approved written consent before participating. Delsys Trigino Wireless EMG sensors were placed on …
