Warming Up With An Ice Vest: Core Body Temperature Before And After Cross-Country Racing, J. Ty Hopkins, Iain Hunter, Douglas J. Casa

Faculty Publications

Context: Athletes running in a hot, humid environment may have an increased risk of heat illness. In the 2004 Olympic Games, American and Australian athletes were provided with ice vests designed to cool their bodies before performance. The vest appeared to be effective in keeping body temperatures down and improving the performance of the marathoners. However, body temperatures have not been reported when the vest was used before an actual competition. Objective: To determine if wearing the Nike Ice-Vest decreased core temperature (Tc) before and during athletic performance in warm (26°C to 27°C), humid (relative humidity = 50% to 75%) …

The Effects Of Wearing A Cooling Vest During The Warm-Up On Long Distance Interval Training, Andrew Robert Tegeder

Theses and Dissertations

Purpose: Reducing body temperature before exercise is called precooling. Past research suggests that reducing body core temperature (Tc) slightly can result in improved running performance. This study evaluated the effects that warming up, while wearing a cooling vest prior to an interval workout, had on Tc, and interval time in long-distance runners. Methods: Nineteen healthy male collegiate cross-country runners were recruited for this study. Each subject warmed up and exercised under two different conditions: (a) an experimental condition in which subjects wore a Nike PreCool® ice vest during warm-up and (b) a control condition. Subjects performed a warm-up followed by …

Contributions Of Muscle Fatigue To A Neuromuscular Neck Injury In Female Standard Ballroom Dancers, Teri Riding

Theses and Dissertations

Objective: To investigate the potential etiology of a loss of neck control injury in female standard ballroom dancers. The median frequency (MF) as measured by electromyography (EMG) of the left upper trapezius (UT), left splenius capitius (SPL), and right sternocleidomastoid (SCM) of injured dancers was compared to non-injured dancers. This comparison was performed to identify whether dancers with a history of loss of neck control have a greater amount of fatigue than those with no history of this particular injury. Design and Setting: A 2 x 6 factorial design was used for this investigation. The independent variables were group (injured …

Development Of A Notational Analysis System For Selected Soccer Skills Of A Women's College Team, Camille Thomas

Theses and Dissertations

The purposes of this study were to develop a notational system to evaluate passing, dribbling, first touch, and individual defensive skills as they relate to success during women's soccer games and to develop a statistical model to weight the importance of each skill on creating scoring opportunities. Sequences of skills in 10 Division I intercollegiate women's soccer games were coded using well defined performance scores and outcomes. The notational analysis system was highly reliable as demonstrated by high test-retest Spearman's correlations (>0.98) between the first and second notation of 3 games for all four skills. The importance scores calculated …

Presence Of Burnout In Undergraduate Athletic Training Students, Tamra Sparks Riter

Theses and Dissertations

Objective: To determine if undergraduate athletic training students enrolled in an athletic training education program (ATEP) and participating in a clinical assignment have burnout and if so, the possible causes.

Design and Setting: All undergraduate athletic training students enrolled in a clinical education course were surveyed twice in an eight week period. The surveys were given during the fourth week and the twelfth week of the winter 2006 semester. As part of the survey, each participant also answered eight demographic/status questions for correlation purposes.

Subjects: Fifty-one undergraduate athletic training students in a western United States university's accredited ATEP served as …

Steeplechase Barriers Affect Women Less Than Men, Tyler D. Bushnell, Iain Hunter

Faculty Publications

Women began contesting the 3000 m steeplechase during the 1990’s using barriers of different dimensions than men. Whenever a new event is introduced for women, consideration should be taken as to whether different technique or training methods should be utilized. This study investigated three aspects of hurdling technique: 1) Differences in the ratio of the landing step to the penultimate step between men and women around each non-water jump steeplechase barrier, 2) differences in step lengths between the four non-water jump barriers, and 3) changes in the step lengths around the barrier throughout the race. The step lengths around the …

Effects Of Ankle Joint Cooling On Peroneal Short Latency Response, J. Ty Hopkins, Iain Hunter, Todd Mcloda

Faculty Publications

While cryotherapy has direct physiological effects on contractile tissues, the extent to which joint cooling affects the neuromuscular system is not well understood. The purpose of the study was to detect changes in ankle dynamic restraint (peroneal short latency response and muscle activity amplitude) during inversion perturbation following ankle joint cryotherapy. A 2x3 factorial design was used to compare reaction time and EMG amplitude data of treatment conditions (cryotherapy and control) across time (pre-treatment, post-treatment, and 30 min post-treatment). Thirteen healthy volunteers (age 23 ± 4 yrs, ht 1.76 ± 0.09 m, mass 78.8 ± 16.6 kg), with no history …

Fiber Type-Specific Desmin Content In Human Single Muscle Fibers, Heidi Ghent

Theses and Dissertations

Contractile and cytoskeletal protein concentrations have been shown to differ on the basis of fiber type in whole muscle homogenates. The purpose of this study was to compare the content of the intermediate filament protein, desmin, between type I and type IIa single muscle fibers from a mixed muscle in human subjects. Biopsies were taken from the vastus lateralis of six recreationally active males. Approximately 150 single muscle fibers were dissected from each sample and analyzed using SDS-PAGE to determine myosin heavy chain (MHC) composition. Following identification, muscle fibers were pooled into two groups (MHC I and MHC IIa). Desmin …

Physical Activity And C-Reactive Protein Levels: The Confounding Role Of Body Fat Percentage, Kenric Lloyd Russell

Theses and Dissertations

The purpose of the present study was to examine the cross-sectional relationship between physical activity and C-reactive protein (CRP) in 211 middle-aged women (43.1 + 3.0 years). A secondary objective was to determine the extent to which body fat percentage operated as a confounder in the association between physical activity and CRP. Physical activity was objectively measured using MTI accelerometers, which the subjects wore for seven continuous days. Fasting blood samples were taken, from which CRP was measured using a solid phase ELISA. Body fat percentage was assessed using the Bod Pod. Results showed that physical activity was significantly and …
