Patellar Tendon Straps Decrease Pain And May Alter Lower Extremity Kinetics In Those With Patellar Tendinopathy During Jump Landing, Adam B. Rosen, Jupil Ko, Kathy J. Simpson, Cathleen N. Brown

Health and Kinesiology Faculty Publications

Patellar tendinopathy is often managed with a patellar tendon strap, however, their effectiveness is unsubstantiated. The purpose of this study was to determine if straps altered pain or lower extremity kinetics of individuals with patellar tendinopathy during landing. Thirty participants with patellar tendinopathy and 30 controls completed drop jumps with and without patellar tendon straps. Wearing the strap, tendinopathy participants demonstrated significantly decreased pain and reduced knee adductor moment; all participants displayed significantly decreased anterior ground reaction force while wearing a strap. Patellar tendon strapping may reduce pain due to alterations in direction and magnitude of loading.

An Examination Of Estimated Bmi And Perceived Wellness Among Students At A Midsized Midwest University, Kylie Kenedy, Eric M. Wiedenman, James W. Ball, Danae Dinkel, Kazuma Akehi, Matthew R. Bice

Health and Kinesiology Faculty Publications

Health is complex and the perception of individual wellness can be influenced by various factors. Students at a Midwestern university estimated their BMI, completed the Perceived Wellness Survey, and had their BMI calculated. Measured BMI was significantly higher than estimated [F(2,155) = 62.03, p = 0.001]. Associations existed between the measured constructs of psychological (r = -0.231; p = 0.004), spiritual (r = 0.248; p = 0.002), and estimated BMI. Data indicates that perceived body composition is related to wellness. False perception of body composition could lead to wellness deficiencies.

The Relationship Between Generalized Joint Laxity And Hip Cartilage Thickness In Ballet And Modern Dancers, Noelle Jeanette Tuttle

Theses and Dissertations

Generalized joint laxity (GJL), a condition in which most joints of the body move beyond the accepted normal range of motion, is present in many ballet and modern dancers. It has been associated with an increased risk of injury, decreased muscle strength, and greater landing forces. Increased joint laxity results in joint instability and may precede the development of osteoarthritis, which is associated with a reduction in cartilage thickness. We hypothesized that dancers with GJL would have decreased hip cartilage thickness, as well as greater hip adduction angles and greater ground reaction force on landings. Twenty female ballet and modern …

The Effects Of A Short-Term Endurance Training Program With Blood Flow Restriction Cuffs Versus Acsm Recommended Endurance Training On Arterial Compliance And Muscular Adaptations In Recreationally Active Males, Brittany N. Esparza

Theses and Dissertations

RESULTS: Significant time and group interaction found in cardiac ejection time (p<.05). Significant condition difference between blood flow restriction (BFR) and control for heart rate (HR) max (p=.05) and maximum oxygen consumption (VO2) (p<.05). Significant time difference found in pulse wave velocity femoral to distal (p<.05). Significant repetition main effect (p<.01) for root mean square (RMS) and median frequency (MDF) of Thorstensson. Significant time and group interaction in vastus lateralis of MDF (p<.01). Significant repetition main effect for RMS and MDF ratio (p<.01) Significant time and repetition interaction in vastus lateralis of RMS ratio (p<.03)

CONCLUSION: The BFR session showed improvement in both post HR max and post VO2 in comparison to the control group. This may have been caused by increased tolerance to pain/metabolic by-products for HR and increased efficiency at extracting oxygen for VO2

Hip Mechanics Of Unilateral Drop Landings, Bobbie S. Irmischer

Human Movement Studies & Special Education Theses & Dissertations

Increased hip forces are a proposed factor for osteoarthritis and femoroacetabular impingement. These forces can be estimated through musculoskeletal modeling using measured kinematics and kinetics. An understanding of hip joint loading during landing in a asymptomatic population will begin to elucidate what, if any, sex differences exist and how changes in landing condition alter hip mechanics. The overall purpose of this dissertation was to explore how sex and landing condition effect landing mechanics. Landing mechanics were quantified using ground reaction forces (GRF), hip joint forces (HJF), and lower extremity kinematics during unilateral drop landings from 30-cm, 40-cm, and 50-cm, as …

The Validity Of Submaximal Exercise Testing In Obese Women, Gabrielle Ringenberg

Mahurin Honors College Capstone Experience/Thesis Projects

Background: Submaximal exercise tests use heart rate responses to low-to-moderate intensity activity in order to predict cardiorespiratory fitness (VO_2max). Currently used tests may be inappropriate for obese populations as obese women have altered heart rate responses to exercise. The purpose of this project is to test the validity of the Modified Bruce Protocol submaximal treadmill test in obese women. Methods: Normal-weight (NWG) and obese women (OBG) completed the Modified Bruce submaximal treadmill test (to predict VO_2max using previously validated equations) and a maximal graded exercise test on a treadmill using the Standard Bruce Protocol (to obtain an …

Affordances In The Home Environment For Motor Development-Infant Scale, Spanish Translation, Danae Dinkel, Kailey Snyder, Priscila Cacola

Health and Kinesiology Faculty Publications

The home environment has a critical influence on an infant’s development and well-being. The Affordances in the Home Environment for Motor Development-Infant Scale (AHEMD-IS) is an instrument that has been developed to assess the home environment. This article illustrates the translation, validation, and cultural adaptation process of the AHEMD-IS from English to Spanish. The AHEMD-IS underwent a comprehensive process involving a four-phase translation process: (1) Forward translation, (2) Semantic equivalence, (3) Content equivalence testing, and (4) Final version development. Steps 1 and 2 resulted in linguistic alterations from the initial translation to enhance clarity for general public understanding. In step …

Assessment Of Endpoint Criteria And Perceived Barriers During Maximal Cardiorespiratory Testing Among Pregnant Women, Caitlin Hesse

Mahurin Honors College Capstone Experience/Thesis Projects

PURPOSE: Plateau in oxygen consumption (VO₂) is the primary indicator for determining if an individual has reached their true maximal aerobic capacity (Howley et al., 1995). Although age and gender-specific secondary criteria (i.e. additional criteria that can be used to identify one’s attainment of maximal effort) have been developed for the healthy population, no secondary criteria have been established for pregnant women (Edvarsen et al., 2014). The primary purpose of this study was to analyze secondary endpoint criteria during VO_2max testing among pregnant women during the 2nd trimester. A secondary purpose was to identify emotional and physical …

Varying Negative Work Assistance At The Ankle With A Soft Exosuit During Loaded Walking, Philippe Malcolm, Sangjun Lee, Simon Crea, Christopher Siviy, Fabricio Saucedo, Ignacio Galiana, Fausto A. Panizzolo, Kenneth G. Holt, Conor J. Walsh

Journal Articles

Background: Only very recently, studies have shown that it is possible to reduce the metabolic rate of unloaded and loaded walking using robotic ankle exoskeletons. Some studies obtained this result by means of high positive work assistance while others combined negative and positive work assistance. There is no consensus about the isolated contribution of negative work assistance. Therefore, the aim of the present study is to examine the effect of varying negative work assistance at the ankle joint while maintaining a fixed level of positive work assistance with a multi-articular soft exosuit.

Methods: We tested eight participants during …

Gait Deficiencies Associated With Peripheral Artery Disease Are Different Than Chronic Obstructive Pulmonary Disease, John D. Mccamley, Eric J. Pisciotta, Jennifer M. Yentes, Shane R. Wurdeman, Stephen I. Rennard, Iraklis I. Pipinos, Jason M. Johanning, Sara A. Myers

Journal Articles

Objective: Previous studies have indicated that patients with peripheral artery disease (PAD), display significant differences in their kinetic and kinematic gait characteristics when compared to healthy, aged-matched controls. The ability of patients with chronic obstructive pulmonary disease (COPD) to ambulate is also limited. These limitations are likely due to pathology-driven muscle morphology and physiology alterations establish in PAD and COP, respectively. Gait changes in PAD were compared to gait changes due to COPD to further understand how altered limb muscle due to disease can alter walking patterns. Both groups were independently compared to healthy controls. It was hypothesized that both …

Muscle Strength And Control Characteristics Are Altered By Peripheral Artery Disease, Molly Schieber, Ryan Hasenkamp, Iraklis Pipinos, Jason Johanning, Nicholas Stergiou, Holly Despiegelaere, Jung Chien, Sara Myers

Journal Articles

Objective

Peripheral artery disease (PAD), a common manifestation of atherosclerosis, is characterized by lower leg ischemia and myopathy in association with leg dysfunction. Patients with PAD have impaired gait from the first step they take with consistent defects in the movement around the ankle joint, especially in plantar flexion. Our goal was to develop muscle strength profiles to better understand the problems in motor control responsible for the walking impairment in patients with PAD.

Methods

Ninety-four claudicating PAD patients performed maximal isometric plantar flexion contractions lasting 10 seconds in two conditions: pain free (patient is well rested and has …

1) An acute exercise stimulus, particularly resistance exercise, and protein ingestion both stimulate muscle protein synthesis (MPS) and are synergistic when protein consumption occurs before or after resistance exercise.

2) For building muscle mass and for maintaining muscle mass through a positive muscle protein balance, an overall daily protein intake in the range of 1.4–2.0 g protein/kg body weight/day (g/kg/d) is …

Posture And Gaze Tracking Of A Vertically Moving Target Reveals Age-Related Constraints In Visuo-Motor Coupling, Haralampos Sotirakis, Anastasia Kyvelidou, Nicholas Stergiou, Vassilia Hatzitaki

Journal Articles

Previously we have demonstrated that the effect of aging on posture and gaze active tracking of a visual target moving in the horizontal direction is dependent on target’s complexity. In this study, we asked whether a similar phenomenon is present when tracking a visual target moving with varying complexity in the vertical direction. Ten young (22.98 ± 2.9 years) and 10 older adults (72.45 ± 4.72 years) tracked for 120 s, a visual target moving vertically by shifting their bodyweight in the anterior-posterior direction. Three target motions were tested: a simple periodic (sine wave), a more complex (Lorenz attractor) and …

He’S Just Content To Sit: A Qualitative Study Of Mothers’ Perceptions Of Infant Obesity And Physical Activity, Danae Dinkel, Kailey Snyder, Anastasia Kyvelidou, Victoria Molfese

Health and Kinesiology Faculty Publications

Background: Rates of obesity among children ages zero to five are rapidly increasing. Greater efforts are needed to promote healthy behaviors of young children. Mothers are especially important targets for promoting health as mothers’ views play a vital role in helping their children foster healthy habits from an early age. Research has found parents’ views of infants’ weight may influence their feeding practices; however, limited research has explored mothers’ view of infants’ weight in relation to the promotion of physical activity. Therefore, the purpose of this study was to explore the perceptions of mothers of normal weight infants and overweight …

Protocol-Dependence Of Middle Cerebral Artery Dilation To Modest Hypercapnia., Baraa K Al-Khazraji, Sagar Buch, Mason Kadem, Brad J Matushewski, Kambiz Norozi, Ravi S Menon, J Kevin Shoemaker

Kinesiology Publications

There is a need for improved understanding of how different cerebrovascular reactivity (CVR) protocols affect vascular cross-sectional area (CSA) to reduce error in CVR calculations when measures of vascular CSA are not feasible. In human participants, we delivered ∼±4 mm Hg end-tidal partial pressure of CO2 (PETCO2) relative to baseline through controlled delivery, and measured changes in middle cerebral artery (MCA) CSA (7 Tesla magnetic resonance imaging (MRI)), blood velocity (transcranial Doppler and Phase contrast MRI), and calculated CVR based on a 3-minute steady-state (+4 mm Hg PETCO2) and a ramp (-3 to +4 mm Hg of PETCO2). We observed …

The Interaction Of Scale And Temperature In Elastically Powered Movements, Jeffrey P. Olberding

USF Tampa Graduate Theses and Dissertations

For many animals, rapid movements place high power demands on underlying muscles. Storage of muscle energy in elastic structures and the subsequent rapid release of that energy can effectively amplify muscle power. Elastic recoil can also confer thermal robustness to performance in behaviors occurring at variable temperatures. Muscle contractile performance tends to decrease at lower temperatures, but elastic recoil is less affected by temperature. Here I examine the impacts of temperature and scale in systems using elastic recoil and I explore possible interactive effects on movement performance.

I explored the role that muscle contractile properties play in the differences in …
