Long-Term Disability Following A Hamstring Injury, Savannah Mclain
Long-Term Disability Following A Hamstring Injury, Savannah Mclain
Electronic Theses and Dissertations
PURPOSE: Injuries to the hamstring complex are one of the most commonly seen lower extremity injuries in athletic populations. It is currently unknown how psychological or sociological factors affect an athlete after the recovery process has ended and if these factors play a role in re-injury rates relating to the hamstring. It is also unknown if athlete confidence level changes while in a fatigued state after an athlete returns to play from a hamstring injury. METHODS: Twenty-six physically active adults with and without a previous hamstring injury were recruited for this study. Participants completed a Qualtrics survey that …
Isolation, Athletic Identity, And Social Support: An Exploration Among Injured Collegiate Student-Athletes, Ally W. Claytor
Isolation, Athletic Identity, And Social Support: An Exploration Among Injured Collegiate Student-Athletes, Ally W. Claytor
Electronic Theses and Dissertations
Season ending and career ending injuries make up a large portion of all injuries (Tirabassi et al., 2016). Among psychological consequences to these types of injuries, isolation is a social consequence that has been identified as occurring after injury (Gould et al., 1997). Isolation is related to loss of identity for an athlete (Mankand et al., 2009). Additionally, low levels of support have been shown to increase feelings of isolation in injured athletes (Mitchell et al., 2014). The purpose of the present study was to explore the experience of isolation as a psychological response to injury among athletes with career …
The Effect Of Nitrate Supplementation On Exercise Tolerance And Performance: A Systematic Review And Meta-Analysis, Gavin Van De Walle
The Effect Of Nitrate Supplementation On Exercise Tolerance And Performance: A Systematic Review And Meta-Analysis, Gavin Van De Walle
Electronic Theses and Dissertations
The purpose of this paper was to systematically review the current literature and evaluate the overall efficacy of nitrate supplementation on exercise tolerance and performance by meta-analysis. Studies were eligible for inclusion if they met the following criteria: 1) were an experimental trial published in an English peer-reviewed journal; 2) compared the effects of inorganic nitrate consumption with a non-bioactive supplement control or placebo; 3) used a quantifiable measure of exercise performance; and 4) was carried out in apparently healthy participants without disease. A total of 29 studies were identified that investigated the effects of nitrate supplementation on exercise tolerance …
The Effect Of Delayed Onset Muscle Soreness On Jumping Mechanics And Performance, Ryan J. Engels
The Effect Of Delayed Onset Muscle Soreness On Jumping Mechanics And Performance, Ryan J. Engels
Electronic Theses and Dissertations
Background: Delayed onset muscle soreness (DOMS) is an exercise-induced muscle soreness resulting from high-intensity eccentric muscular contractions. DOMS appears to be more prevalent in athletes at the beginning of an athletic season or when new movements or exercise are first introduced. The acute effect of DOMS on jumping mechanics is currently unknown. PURPOSE: The purpose of this study is to determine the effect of delayed onset muscle soreness on vertical jump performance and jumping mechanics. METHODS: Twenty college aged, recreationally active males participated in this study (age: 21.54 ± 2.61; height: 1.82 ± 0.067; mass: 81.36 ± 9.53). Participants were …
Utilization Of B-Mode Ultrasound As A Body Fat Estimate In Collegiate Football Players, Parker Hyde
Utilization Of B-Mode Ultrasound As A Body Fat Estimate In Collegiate Football Players, Parker Hyde
Electronic Theses and Dissertations
The purpose of the present study was to validate a 7-site ultrasound imaging protocol to predict percent body fat (%BF) in a Division I football team. Body composition was estimated by ultrasound, seven site skinfolds (SKINFOLD), and the three compartment-water (3C-W) model of Siri (1961), using Bioimpedance spectroscopy (BIS) to estimate total body water (TBW) and air-displacement plethysmography (BODPOD®) to determine body density (Db). Pearson’s product-moment correlation analyses were run to determine between ΣUltrasound and the criterion 3C-W, and between the ΣSkinfold and ΣUltrasound. Strong positive correlations were observed between ΣSkinfold and Σ …
