All Faculty Scholarship for the College of Education and Professional Studies

Maximal oxygen uptake (VO₂max) declines with advancing age and is a predictor of morbidity and mortality risk. The purpose here was to assess the utility of constant load tests performed either above or below peak work rate obtained from a graded exercise test for verification of VO₂max in older adults. Twenty-two healthy older adults (9M, 13F, 67 ± 6 years, BMI: 26.3 ± 5.1 kg·m⁻²) participated in the study. Participants were asked to complete two experimental trials in a randomized, counterbalanced cross-over design. Both trials (cycle ergometer) consisted of (1) an identical graded exercise …

Influence Of The Bar Position On Joint-Level Biomechanics During Isometric Pulling Exercises, Nayun Ahn, Hoon Kim, John Krzyszkowski, Stuart Roche, Kristof Kipp

Exercise Science Faculty Research and Publications

The purpose of this study was to investigate the influence of the bar position on ankle, knee, and hip net joint moments (NJMs), relative muscular effort (RME), and vertical ground reaction forces (GRFs) during isometric pulling exercises, such as the isometric midthigh pull. Eight female lacrosse athletes performed maximal effort isometric pulls at 3 different bar positions (low: above patella, mid: midthigh, and high: crease of hip) while motion capture and GRF data were recorded. Net joint moments were calculated with inverse dynamics. Relative muscle effort was defined as the ratio between the inverse dynamics NJMs and the maximum theoretical …

Menstrual Dysfunction As The Leading Clinical Marker For The Future Development Of The Female Athlete Triad: A Meta-Analysis, Sydney Hotz

Health and Kinesiology Theses

The Female Athlete Triad is a diagnosable medical condition that is under researched and very prevalent in female sports today. The development of the Female Athlete Triad, or any of its components, can negatively impact many aspects of a female athlete’s life. If clinical markers could be identified that indicate future development of the Triad, it could potentially help prevent occurrence of the condition and greatly reduce the number of female’s that have to suffer from it. Menstrual dysfunction could be the leading clinical marker for the future development of the Triad. This meta-analysis seeks to explore the possible association …

The Reliability Of Tensiomyography For Assessment Of Muscle Function: A Systematic Review, Stephon Moise, Daniel Hampton

UCF DPT Research Capstone

Tensiomyography (TMG) is a non-invasive tool used to assess skeletal muscle tissue, including Displacement (Dm), Contraction Time (Tc), Sustain Time (Ts), Relaxation Time (Tr), and Delay Time (Td). This tool can be used clinically to determine muscular response to exercise.

PURPOSE: The purpose of this study was to investigate the reliability of TMG measurements.

METHODS: Studies were identified from multiple databases and evaluated for inclusion. All studies underwent a quality assessment using the Modified Downs and Black checklist for assessing quality studies, and results were extracted from qualified articles.

RESULTS: 635 studies were identified with 16 studies retained following full …

Side-To-Differences Of Medial Elbow Anatomy Adaptations In Youth Throwing Athletes, Rudolph Matthew Morrow

Theses, Dissertations and Capstones

Background: Injuries to the medial elbow are common in overhead sports, with the most common occurring at the medial/ulnar collateral ligament (UCL). Injury to the UCL is associated with elbow joint laxity which tends to develop over time in athletes who place their elbows under chronic valgus forces like those present during throwing. ^{27, 37} This instability is well documented in professional, collegiate, and high school athletes.

Purpose: The purpose of this study was to investigate the medial elbow joint width and common flexor tendon thickness in the arms of youth baseball players. The hypotheses were (1) the …

Development Of A Field Expedient Screening Tool For The Coach To Identify Musculoskeletal Risk Factors In Baseball Players, Kyle Andrew Matsel

Theses and Dissertations--Rehabilitation Sciences

Identification of musculoskeletal (MSK) injury risk factors in baseball players can be challenging particularly for youth and high school coaches. Many baseball coaches lack a sports medicine and/or strength and conditioning staff to assist with injury prevention initiatives. Given the extensive responsibilities in managing the team and preparing the players for athletic competition, little time remains to focus on injury prevention and arm care programs. Furthermore, assessment, diagnosis, and management of MSK impairments is outside the scope of practice and expertise of baseball coaches. However, educating and empowering the coach to efficiently screen their players for potentially injury producing MSK …
