No Changes In Appetite-Related Hormones Following Swimming And Cycling Exercise Interventions In Adults With Obesity, Brandon G. Fico, Mohammed Alkatan, Hirofumi Tanaka

International Journal of Exercise Science

International Journal of Exercise Science 13(2): 1819-1825, 2020. Swimming is a favorable and ideal modality of exercise for individuals with obesity and arthritis as it encompasses a minimal weight-bearing stress and a reduced heat load. However, the available evidence indicates that regular swimming may not be effective in reducing body weight and body fatness. A current hypothesis is that exercise in cold water stimulates appetite. We determined the effect of swimming training on appetite-related hormones. Thirty-nine adults with obesity and osteoarthritis were randomly assigned to 12 weeks of supervised swimming or cycling training. In the initial few weeks, participants exercised …

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 …

Health and Kinesiology Faculty Publications

The urgency to develop a vaccine against the 2019 coronavirus (COVID-19) has waxed stronger in speed, scale, and scope. However, wisdom dictates that we take a vantage position and start to examine the demographic predictors of COVID-19 vaccine hesitancy. The objective of this study was to examine the role of health locus of control (HLOC) in the relationship between religiosity and COVID-19 vaccination intention. In a cross-sectional survey (N = 501), we found a significantly negative association between religiosity and COVID-19 vaccination intention. This relationship was partially mediated by external HLOC. Collaborative efforts with religious institutions may influence COVID-19 vaccine …

Biomechanics Of Independent Wheelchair Transfer In Individuals With Spinal Cord Injury, Ashleigh L. Fults

USF Tampa Graduate Theses and Dissertations

AbstractIndividuals with a low level spinal cord injury (SCI) at T1 or below must use a wheelchair for mobility and in order to accomplish daily activities, such as using a recreational wheelchair for sports. These individuals must transfer into and out of their wheelchair several times a day. It is most beneficial for the individual to complete these transfers independently, without the help of a caretaker or assistive device. It is important that these transfers be successful and safe, because improper technique can result in a serious injury from a fall or by repeated small damage to the arms and …

Differences Between Joint-Space And Musculoskeletal Estimations Of Metabolic Rate Time Profiles, Arash Mohammadzadeh Gonabadi, Prokopios Antonellis, Philippe Malcolm

Journal Articles

Motion capture laboratories can measure multiple variables at high frame rates, but we can only measure the average metabolic rate of a stride using respiratory measurements. Biomechanical simulations with equations for calculating metabolic rate can estimate the time profile of metabolic rate within the stride cycle. A variety of methods and metabolic equations have been proposed, including metabolic time profile estimations based on joint parameters. It is unclear whether differences in estimations are due to differences in experimental data or due to methodological differences. This study aimed to compare two methods for estimating the time profile of metabolic rate, within …

International Journal of Exercise Science

International Journal of Exercise Science 13(4): 1718-1728, 2020. The purpose of this study was to compare the Skulpt Chisel™ to seven-site skinfold (SKF) and hydrostatic weighing (HW) body fat percentage (%BF) estimates. Twenty-six participants (aged 24 ± 4 years; BMI 23.1 ± 3.5 kg∙m^-2) were assessed. Significant differences in %BF estimates were found for all methodological pairings; p < 0.05. The SKF method underestimated %BF compared to HW (-2.52 ± 3.42 %BF). The Skulpt Chisel™ overestimated %BF compared to both HW (3.38 ± 6.10 %BF) and SKF (5.90 ± 5.26 %BF). Limits of agreement comparing HW to Skulpt Chisel™ indicated a difference between 95% confidence interval bounds (Upper bound: 5.84 %BF, Lower bound 0.92 %BF) and for HW to SKF (Upper bound: -1.14 %BF, Lower bound: -3.91 %BF). Regression analysis showed no significant bias for any methodological pairing; (p > 0.05). In conclusion, the Skulpt Chisel™ method should be used with caution when evaluating %BF of adults with similar demographics reported in this study.

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 …
