Biomechanical Properties Of Land Based And Shallow Water Wait: A Comparative Review Of Literature, Mostafa Yaghoubi, Philip Fink, Wyatt H. Page, Sarah P. Shultz

International Journal of Aquatic Research and Education

Aquatic locomotion exercises are frequently used in rehabilitation and cross-training for land-based athletes. Hydrostatic pressure, thermal conductivity and drag force affect a person's ability to move; therefore, it is important to understand differences of biomechanical gait in water vs land. This review investigated biomechanical differences between shallow water and land-based exercises. PubMed, Google Scholar, SPORTDiscus and Scopus were searched; 33 studies included walking forward (27), backward (6) and running (6). Electromyographic amplitude was similar or less in submaximal intensity during aquatic gait, in comparison to on land. At maximal intensities, however, the amplitude was similar (n=5) or higher (n=4) in …

Changes In Lifeguards’ Hazard Detection And Eye Movements With Experience: Is One Season Enough?, Jennifer Smith, Geoff Long, Peter Dawes, Oliver Runswick, Michael J. Tipton

International Journal of Aquatic Research and Education

Surveillance is key to the lifesaving capability of lifeguards. Experienced personnel consistently display enhanced hazard detection capabilities compared to less experienced counterparts. However, the mechanisms which underpin this effect and the time it takes to develop these skills are not understood. We hypothesized that, after one season of experience, the number of hazards detected by, and eye movements of, less experienced lifeguards (LEL) would more closely approximate experienced lifeguards (EL). The LEL watched ‘beach scene’ videos at the beginning and end of their first season. The number of hazards detected and eye-movement data were collected and compared to the EL …

Force And Emg Comparison Between A Weight-Bearing Clinical Assessment Of Hip Strength Assessment And Non-Weightbearing Tasks, Kemery J. Sigmund, Jennifer E. Earl-Boehm

Journal of Sports Medicine and Allied Health Sciences: Official Journal of the Ohio Athletic Trainers Association

Purpose: Altered hip strength is a risk factor for lower extremity injury but its relationship to biomechanical dysfunction is debated. Hip strength assessment methods are criticized for using unidirectional, non-weight-bearing positions which may not be representative of athletic activity and may affect comparison to biomechanical analysis of athletic tasks. A weight-bearing task may better represent hip muscle function during these movements. The aim of this study was to identify EMG and force differences for a clinical weight-bearing method of hip strength (the squat-hold) to traditional non-weight-bearing maximal voluntary isometric contractions (MVICs) for hip abduction, extension, and external rotation. Methods: Twenty-nine …

Effect Of Age At Menarche On Anterior Cruciate Ligament Injury Incidence And Anterior Knee Laxity In Collegiate Athletes, Andrew W. Froehle, Joseph T. Cox, Jedediah H. May, Kimberly A. Grannis, Dana L. Duren

Journal of Sports Medicine and Allied Health Sciences: Official Journal of the Ohio Athletic Trainers Association

Female athletes suffer painful, costly, and career-limiting non-contact anterior cruciate ligament (ACL) injuries more often than males. Previous research suggests that pubertal neuromusculoskeletal development contributes to this sex-bias, but the manner in which variation in pubertal development affects injury risk within females is poorly understood. Age at menarche is a variable, significant pubertal developmental event, signaling the onset of estrogen cycling and affecting musculoskeletal development. Earlier menarche may increase injury risk, possibly by increasing anterior knee laxity through prolonged estrogen exposure. The purpose of this case-control study was to test the primary hypothesis that collegiate athletes with previous ACL injuries …

Recurrent Patellar Fracture in a Healthy Collegiate Basketball Player: An Exploration Clinical Case Report

ABSTRACT

Purpose: Patellar fractures only account for approximately 1% of all skeletal injuries. Patellar fractures usually result from direct trauma (i.e. falling on the knee, dashboard injury, etc.), or, less frequently, occur as a combination of direct and indirect mechanism (i.e. receiving a direct blow while contracting the quadriceps). While indirect trauma is the least common mechanism, it usually occurs due to an extensor mechanism failure during eccentric loading such as landing. Method: Case report, Level 3: Exploration Clinical Contribution to the Available Sources of Evidence …

Winning In Weight-Loss: The Interaction Of Conscientiousness And Perceived Autonomy, Jason M. Curtis, Marc Lochbaum

Journal for Sports Neuroscience

ABSTRACT

Background

Understanding determinants for weight-loss is a national priority. Obesity is an epidemic with serious health consequences. Most of today’s obesity and overweight problems are being attributed to poor diets and not enough physical activity. These problems show no signs of slowing down with the behaviors of most Americans. The phenomenon of “The Biggest Loser” (different variants of weight-loss programs that consist of group exercise participation and nutrition therapy to elicit weight-loss, and hopefully behavior change) has spawned many variants in commercial health clubs. This prospectus study examined the direct and interactive or moderated effects of known determinants of …

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 …
