Fatigue Changes Biomechanical Variables In Drop Vertical Jump Performance In Competitive Basketball Players, Isabella Bruno, Caroline Linardos, Michala Rennels, Kristina Williams, Robin Dorociak, Jaydee Romick, Jason Brumitt

Student-Faculty Research - College of Physical Therapy

The drop vertical jump (DVJ) has been used as a tool to identify athletes at risk for injury. Initial studies have suggested an association between biomechanical variables and injury (1); however, subsequent research has demonstrated no relationship (2-4). Evaluating variables in fatigued athletes may help clinicians identify athletes at risk. Advances in motion capture technology now allow for assessment of variables after a fatigue protocol.

Does The Size-Weight Illusion Exist During Deadlift?, Dakota Kerbow, Luke Mallory, Robin Dorociak, Peter Jang, Andrew Meszaros

Student-Faculty Research - College of Physical Therapy

Purpose:

to assess whether the SWI exists during deadlift (whole body loading), and identify the mechanical factors that explain or overcome the illusion

Can Preseason Performance Tests Discriminate Injury Risk In Female Collegiate Volleyball Players, Justine Benner, Heidi Cooke, Colby Critchfield, Samantha Dunn, Sarah Eddy, Linda Froemming

Student-Faculty Research - College of Physical Therapy

Purpose: Prior research has demonstrated a 4-fold greater risk of a non-contact time-loss lower quadrant injury in collegiate female VB players (3). The purpose of this study was to validate effectiveness of functional performance tests to discriminate injury risk in female collegiate volleyball players.

Patellar Tendonopathy In Collegiate Volleyball Athletes, Justine Benner, Heidi Cooke, Colby Critchfield, Samantha Dunn, Sarah Eddy, Linda Foremming

Student-Faculty Research - College of Physical Therapy

Purpose: The first purpose was to identify the prevalence of patellar tendon abnormality in female collegiate volleyball players. The second purpose was to identify a potential association between kinetic measures during the drop vertical jump between those with tendon abnormality and those without in female collegiate volleyball athletes

Kinetic And Kinematic Analysis Of Male Collegiate Basketball Players With Patella Tendinosis, Dacia Heckendorf, Luke Hammer, Matthew Jeppson, Nicole Jones, Katherine Porter

Student-Faculty Research - College of Physical Therapy

Patellar tendinopathy (PT) occurs in approximately 40% of elite jumping athletes. Players will typically play through the pain; however, if the condition is not successfully treated some are forced to retire from sport. Research has shown that there are no signs of chemical inflammation in the tendon, but rather the presence of a degenerative tendon with collagen disorientation and disorganization.

Comparison Of Four Fitbit And Jawbone Activity Monitors With A Research-Grade Actigraph Accelerometer For Estimating Physical Activity And Energy Expenditure, Mary T. Imboden, Michael B. Nelson, Leonard A. Kaminsky, Alexander Hk Montoye

Faculty Publications - Department of Kinesiology

Background/aim Consumer-based physical activity (PA) monitors have become popular tools to track PA behaviours. Currently, little is known about the validity of the measurements provided by consumer monitors. We aimed to compare measures of steps, energy expenditure (EE) and active minutes of four consumer monitors with one research-grade accelerometer within a semistructured protocol.

Methods Thirty men and women (18–80 years old) wore Fitbit One (worn at the waist), Fitbit Zip (waist), Fitbit Flex (wrist), Jawbone UP24 (wrist) and one waist-worn research-grade accelerometer (ActiGraph) while participating in an 80 min protocol. A validated EE prediction equation and active minute cut-points were …

The Role Of Balance And Neck Strength In Youth Concussion, Chris Koch, Jenny Neudorfer, Peter Heuberger, Tel Winegar, Calvin Lee, Jarrett Fegel

Student-Faculty Research - College of Physical Therapy

Concussion: A concussion is a trauma-induced alteration in mental status that may or may not involve loss of consciousness; this can include a direct blow to the head or a blow to the body resulting in the head and brain moving quickly back and forth (1).

Current Screen: Current concussion screen consists of: symptom checklist, cognitive assessment known as Sport Concussion Assessment Tool (SCAT), and Balance Errors Scoring System (BESS) (2).

Purpose: The purpose of this study is to determine an assessment to screen an individual’s risk of sustaining a sport-related concussion.

Hypothesis: We hypothesized the SCAT 4, BESS, Four …

High Prevalence Of Nontraumatic Shoulder Pain In A Regional Sample Of Female High School Volleyball Athletes, Kayt E. Frisch

Faculty Publications - Biomedical, Mechanical, and Civil Engineering

Background: Shoulder pain is becoming increasingly problematic in young players as volleyball gains popularity. Associations between repetitive motion and pain and overuse injury have been observed in other overhand sports (most notably baseball). Studies of adult athletes suggest that there is a shoulder pain and overuse problem present in volleyball players, but minimal research has been done to establish rates and causes in juvenile participants.

Purpose: To establish rates of shoulder pain, regardless of whether it resulted in a loss of playing time, in female high school volleyball players. A secondary goal was to determine whether high repetition volumes correlated …

Are Preseason Functional And Biomechanical Measures Associated With Lower Quadrant Injury Risk In Division Iii Athletes?, Natalie Ellis, Jordan Petersen, Jordon Reyes, Victor Wilson, Cj Zita

Student-Faculty Research - College of Physical Therapy

A recent trend in sports medicine research is to determine risk of injury during sport based on preseason functional performance test (FPT) measures.

Equivocal findings associated with prior studies may leave PTs with uncertainty as to which FPT, or combination of FPTs, can best identify athletes who have a greater risk for injury.

Previous studies have utilized "low-tech" FPT measures: standing long jump (SLJ), single-leg hop (SLH), lower extremity functional test (LEFT), and the Y-balance test (YBT) (1,3,4).

These "low-tech" options may not be able to identify potential deficits that could be collected with "high-tech" measures (e.g., DVJ measures collected …

The Lower-Extremity Functional Test And Lower-Quadrant Injury In Ncaa Division Iii Athletes: A Descriptive And Epidemiologic Report, Jason Brumitt, Bryan C. Heiderscheit, Robert C. Manske, Paul Niemuth, Alma Mattocks, Mitchell J. Rauh

Faculty Publications - College of Physical Therapy

Context: The Lower-Extremity Functional Test (LEFT) has been used to assess readiness to return to sport after a lower extremity injury. Current recommendations suggest that women should complete the LEFT in 135 s (average; range 120-150 s) and men should complete the test in 100 s (average; range 90-125 s). However, these estimates are based on limited data and may not be reflective of college athletes. Thus, additional assessment, including normative data, of the LEFT in sport populations is warranted. Objective: To examine LEFT times based on descriptive information and off-season training habits in NCAA Division III (Dill) athletes. In …

Preventing Running Injuries Using A Pre-Running Exercise Program (Prep): A Pilot Study, P. Jaques, T. Mcgrath, K. Rasmussen, J. Irwin, J. Winslow, M. Strong, G. Macias, Tyler Cuddeford

Student-Faculty Research - College of Physical Therapy

Hypothesis: An 8 week supervised PREP implemented prior to a 5k running program will reduce the incidence of RRI's among novice runners training for a 5k below the previously published incidence rates.
