Intention To Vaccinate Against The Novel 2019 Coronavirus Disease: The Role Of Health Locus Of Control And Religiosity, Ayokunle Olagoke, Olakanmi Olagoke, Ashley M. Hughes

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 …

The shared variance between CMJ height and core strength measurements was estimated using …

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.

International Journal of Exercise Science

International Journal of Exercise Science 13(3): 1729-1740, 2020. Little is known about the physiological response to the cold pressor test (CPT) when in a clinically-induced state of autonomic nervous system (ANS) imbalance, despite its utility in various disease- and injury-states. To date, research in this area is limited to acute aerobic and isometric exercise, with a paucity of research investigating the effects of anaerobic exercise on the physiological response to the CPT. Therefore, the purpose of our study was to assess the effects of the Wingate anaerobic cycle test (WAT) on cardiovascular (CV) and metabolic recovery following the CPT in …

Use Of Heart Rate Index To Predict Oxygen Uptake – A Validation Study, Jie Kang, Nicholas A. Ratamess, Avery D. Faigenbaum, Jill A. Bush-Wallace, Christopher Roser, Devyn Montemarano, Hannah Mercado, Morgan Choma, Christian Mendez, Matthew Pollock

International Journal of Exercise Science

International Journal of Exercise Science 13(7): 1705-1717, 2020. An equation that uses heart rate index (HRI) defined as HR/HRrest to predict oxygen uptake (VO₂) in METs (e.g., METs = 6 × HRI ‒ 5) has been developed retrospectively from aggregate data of 60 published studies. However, the prediction error of this model as used by an individual has not been established. Therefore, the purpose of this study was to examine the predictive validity of the HRI equation by comparing submaximal and maximal VO₂ predicted by the equation (VO₂-Pred) with that measured by indirect calorimetry (VO …

International Journal of Exercise Science

International Journal of Exercise Science 13(3): 1638-1649, 2020. The aims of this study were: (i) to analyze the relationship between the performance of different measures of muscular strength, and (ii) to identify which measurements present a greater relationship with an overall strength score. Sixty older women (aged 69 ± 6 years) were submitted to muscular strength measurements from isotonic, isokinetic, and isometric tests. An overall-strength score was generated with z-scores of the values obtained in all tests. Interquartile intervals were created for each measure and the overall-strength score. Pearson’s r (0.463-0.951, p < 0.05) and Cronbach’s α (0.500-0.966) suggested that subjects had relatively similar strength performance compared to their peers in the different tests. Greater associations were observed between tests for similar tasks. In addition, strong-magnitude associations were revealed between all the tests and the overall-strength score (r = 0.710-0.806; α = 0.760-0.846). Factor …

Functional Gait Asymmetries Achieved Through Modeling And Understanding The Interaction Of Multiple Gait Modulations, Fatemeh Rasouli

USF Tampa Graduate Theses and Dissertations

Walking is an important determinant of human functionality. Gait disabilities affect millions of people worldwide every year. Investigating the science of walking advances recovery techniques and assistive devices for gait rehabilitation. A functional gait promotes productivity, independence, and quality of life. Human gait, like any other moving mechanism, is a dynamic system. Understanding and analyzing the dynamic aspects of gait improves the recovery methods to fundamentally affect and interact with lower limbs.

This dissertation aims to fill the gaps in mechanical simulations of gait and dynamic analysis of rehabilitation techniques. The solutions consider kinematic, kinetic, and spatiotemporal parameters of gait …

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 …

The purpose of this study was to identify the underlying factors that contributed to adolescents’ perceptions of injury and the various pressures they experienced when returning to sport. Two themes emerged from the study: support and fear. Support was provided to participants through development, care, and the environment. Fear was the factor that affected the participant in their return to sport, which came in the …

Recurrent Patellar Fracture In A Healthy Collegiate Basketball Player: An Exploration Clinical Case Report, Mikaela Boham, Jerry Hilker

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

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 …
