Objective: To determine the effect of lower body exercise on deltoid cooling during 1-kg ice bag treatment and post treatment rewarming, separately. Design: Two ( during and after ice application) 2 X 5 repeated measures designs with the treatment condition (bike and rest) and time (baseline, 1-, 10-, 20-, and 30-minutes during …

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 …

Effect Of A Single Bout Of Prior Moderate Exercise On Cutaneous Perfusion In Type 2 Diabetes, Sheri R. Colberg, Henri K. Parson, Tanja Nunnold, D. Robb Holton, Aaron I. Vinik

Human Movement Studies & Special Education Faculty Publications

In diabetic individuals, increased shunting of circulation away from the skin may exist, contributing to their greater risk for ulcerations and poor cutaneous healing. In a prospective study (1), we previously found a lower skin perfusion during local heating in the foot dorsum of sedentary type 2 diabetic individuals compared with active people without diabetes. This defect was present despite normal increases in skin interstitial nitric oxide (NO), suggesting that NO is either ineffective or not involved (2). A prior bout of maximal exercise also lessened the impaired responsiveness to local heating of the dorsal foot in active type 2 …

An Electromyographic Assessment Of Lumbar Paraspinal Muscles During Core Stability Exercises, Alicia Marleina Osuna

Public Posting As A Strategy To Increase Walking: A Worksite Intervention, Rayleen Earney, Timothy J. Bungum

Environmental & Global Health Faculty Research

Because most American adults do not meet recommended physical activity guidelines, the need for new and innovative strategies is apparent. The current study employed public posting in an attempt to increase walking behavior in a worksite setting. Pedometer generated data was publicly posted in a prominent location in the worksite. In our study that utilized a pre-experimental design, we found that walking steps were statistically higher during the intervention and in a post intervention period as compared to the baseline data. We conclude that the public posting of physical activity data has the potential to increase walking behavior.

Is There A Threshold Intensity For Aerobic Training In Cardiac Patients?, David P. Swain, Barry Franklin

Human Movement Studies & Special Education Faculty Publications

Purpose: Recent guidelines have recommended the use of a percentage of oxygen uptake reserve ((V) over dot O₂R) for prescribing aerobic exercise intensity for cardiac patients. Moreover, these guidelines suggest that a threshold intensity may exist, below which no improvement in peak oxygen uptake ((V) over dot O-_2peak) occurs, The purpose. therefore. was to translate the intensity of aerobic exercise in previous training studies using cardiac patients into %(V) over dot O₂R units, and determine whether a threshold intensity exists, Methods: Twenty-three studies, using 28 groups of aerobically trained cardiac patients. were identified in …

A Study Designed To Establish Norms For The Marine Corps Physical Fitness Test Utilizing Somatotypes, Dean A. Blevins

All Master's Theses

The purpose of this study is to develop norms for the Marine Corps Physical Fitness Test in each somatotype classification as determined by the Heath-Carter anthropometric measurement. At the present time, norms exist only for the group as a whole which is comprised mainly of mesomorphs. This, of course, results in a great many endomorphs who score poorly, or not at all, and some ectomorphs who also do poorly. It is proposed that endomorphs, ectomorphs, and mesomorphs should each have their own norms.
