Black Drowning Deaths: An Introductory Analysis, Alena Gadberry, James Gadberry

International Journal of Aquatic Research and Education

Black children between the ages of 5 and 14 are 2.6 times more likely to drown than white children. A systematic exclusion from public pools and other forms of water activities over time has led to a lack of cultural capital involving aquatics among black families. Pierre Bourdieu has provided a theoretical foundation in which to understand this issue. The social fields created by generational socialization have made blacks feel like they have no place in the water. It will take a restructuring of the social institutions to set in motion the socialization (or a re-socialization) of new and more …

Reliability Of The Styku 3d Whole Body Scanner For The Assessment Of Body Size In Athletes, Joe D. Derouchey, Grant R. Tomkinson, Jesse L. Rhoades, John S. Fitzgerald

Education, Health & Behavior Studies Faculty Publications

Anthropometry is important for predicting sport performance. While 3-dimensional (3D) body scanners increase the feasibility of anthropometric assessment, reliability data on athletes are lacking. The aim of this study was to determine the test-retest reliability of a portable, single-camera 3D body scanning system (Styku S100) to assess circumferences, and whole-body and segmental surface areas and volumes of athletes. Forty-nine (19 male) athletes were scanned six times (two sessions of three scans). The Styku scanner demonstrated nearly perfect reliability. Systematic errors were negligible (mean standardized bias [95%CI]: scan 1 vs. 4, 0.04 [0.02, 0.06]), random errors were negligible (mean standardized typical …

Calculating An Equation To Estimate The Maximum Oxygen Uptake In Lifeguards, Brais Ruibal-Lista, José Palacios-Aguilar, José Antonio Prieto, Sergio López-García, Miguel Santiago-Alonso, José Antonio Cecchini-Estrada, Cristian Abelairas-Gómez

International Journal of Aquatic Research and Education

The aim of this study was to derive an equation that validly and reliably estimates the VO₂ reached in the IPTL, a maximum stress test for lifeguards. From the results obtained in the first part of the research, a multiple linear regression model was identified. A "stepwise" procedure was established as a variable selection method, where the VO_2IPTL was selected as the dependent variable and the maximum time reached in the IPTL (s), the percentage of muscle mass (%) and weight of the participant (kg), as independent variables. This procedure generated a regression model where a high correlation …

Portuguese Lifeguards Performance In Aquatic Rescue: An Exploratory Study, Olga G. Marques Ph.D., José Palacios-Aguilar Ph.D, Henrique G. Melo Mcs., Nuno G. Leitão, Lucia P. Castillo Msc., David Szpilman M.D, Luís Rama Ph.D.

International Journal of Aquatic Research and Education

The objective of the study was to compare the performance of Portuguese lifeguards in two trials of simulated rescue at the beach within a regular continuous workday. Additionally, the study aimed to analyse the influence of experience and initial course syllabus on the rescue performance. A total of 86 Portuguese lifeguards (LG) participated in this study, 69 males and 17 females. The two simulated drowning occurrences were planned to occur at 50 meters from the coastline between 9.00h am and 18.00h pm. The weather conditions, the characteristics of the beach, wave amplitude were also controlled. The results were analysed through …

Acute Effects Of Kinesiology Tape Tension On Soleus Muscle H-Reflex Modulations During Lying And Standing Postures, Yung Sheng Chen, Wei Chin Tseng, Che Hsiu Chen, Pedro Bezerra, Xin Ye

Faculty and Student Publications

Copyright: © 2020 Chen et al. This is an open access article distributed under the terms of the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original author and source are credited. Kinesiology tape (KT) has been widely used in the areas of sports and rehabilitation. However, there is no gold standard for the tape tension used during a KT application. The purpose of this study was to examine the effects of KT application with different tension intensities on soleus muscle Hoffmann-reflex (H-reflex) modulation during lying and standing postures. Fifteen healthy university …

Greater Fatigability And Motor Unit Discharge Variability In Human Type 2 Diabetes, Jonathon Senefeld, Kevin G. Keenan, Kevin S. Ryan, Sarah E. D'Astice, Francesco Negro, Sandra K. Hunter

Exercise Science Faculty Research and Publications

This study determined the discharge characteristics of motor units from two lower limb muscles before and after fatiguing exercise in people with type 2 diabetes (T2D) with no symptoms of polyneuropathy and activity-matched controls. Seventeen people with T2D (65.0 ± 5.6 years; 8 women) and 17 controls (63.6 ± 4.5 years; 8 women) performed: (a) intermittent, isometric contractions at 50% maximal voluntary isometric contraction (MVIC) sustained to failure with the ankle dorsiflexors, and (b) a dynamic fatiguing task (30% MVIC load) for 6 min with the knee extensors. Before and after the fatiguing tasks, motor unit characteristics (including coefficient of …

Thrower's Exostosis Of The Shoulder: A Systematic Review With A Novel Classification, Michael T. Freehill, Sandeep Mannava, Laurence D. Higgins, Alexandre Lädermann, Austin V. Stone

Orthopaedic Surgery and Sports Medicine Faculty Publications

Background: A variety of thrower's exostoses are grouped under the term Bennett lesion, which makes understanding diagnosis and treatment difficult.

Purpose: To identify all types of reported thrower's and overhead athlete's exostoses and categorize them into a classification system to allow a morphology-based classification.

Study Design: Systematic review; Level of evidence, 4.

Methods: A systematic review of all articles pertaining to Bennett lesions and thrower's exostosis was performed. The classification and treatments were evaluated to describe the types, proposed causes, diagnosis, and treatment options.

Results: A total of 27 studies were included in the systematic review. The anatomic locations …

The Effects Of Two Modes Of High-Intensity Intermittent Exercise On Postprandial Metabolism, David J. Buckley

Electronic Theses and Dissertations

The purpose of this study was to see if exercise in the form of Tabata or Sprinting would lower postprandial lipemia and glycemia. Tabata was composed of body-weight exercises. Both Tabata and Sprinting consisted of 5 rounds with each round lasting 4 minutes and included movements performed for 20 seconds followed by 10sec of rest. Following the completion of each round, participants received a 60 second break. Both exercise sessions were isocaloric and lasted 25min. Thirty minutes following exercise, participants were given a 75g-oral glucose solution and a high-fat meal two hours following exercise. The postprandial assessment lasted 6 hours. …

Teaching Foundational Aquatic Skills To Children In Open Water Environments, Chris Button, Angela J. Button, Anne-Marie Jackson, Jim D. Cotter, Brian Maraj

International Journal of Aquatic Research and Education

Learning to swim in a swimming pool might not prepare water competence sufficiently for different aquatic environments. The aim of this study was to assess the effectiveness of teaching children water safety knowledge and skills in open water environments (i.e., harbor, river, and surf). The aquatic knowledge and skills of 98 children (7-11 years old) were tested in a swimming pool before, immediately after, and three months after receiving a three-day intensive education program. At pre-test, typically fewer than 50% of children achieved a high level of water safety competence. After the program, competency in each of the six tasks …
