Oral Glutamine Supplement Reduces Subjective Fatigue Ratings During Repeated Bouts Of Firefighting Simulations, Mary Moore, Terence A. Moriarty, Gavin Connolly, Christine Mermier, Fabiano Amorim, Kevin Miller, Micah Zuhl

Faculty Publications

Wildland firefighting requires repetitive (e.g., consecutive work shifts) physical work in dangerous conditions (e.g., heat and pollution). Workers commonly enter these environments in a nonacclimated state, leading to fatigue and heightened injury risk. Strategies to improve tolerance to these stressors are lacking. Purpose: To determine if glutamine ingestion prior to and after consecutive days of firefighting simulations in the heat attenuates subjective ratings of fatigue, and evaluate if results were supported by glutamine-induced upregulation of biological stress responses. Methods: Participants (5 male, 3 female) ingested glutamine (0.15 g/kg/day) or a placebo before and after two consecutive days (separated by 24 …

Recommendations For Measurement And Management Of An Elite Athlete, William Sands, Marco Cardinale, Jeni Mcneal, Steven Murray, Christopher Sole, Jacob Reed, Nikos Apostolopoulos, Michael Stone

Faculty Publications

Athletes who merit the title elite' are rare and differ both quantitatively and qualitatively from athletes of lower qualifications. Serving and studying elite athletes may demand non-traditional approaches. Research involving elite athletes suffers because of the typical nomothetic requirements for large sample sizes and other statistical assumptions that do not apply to this population. Ideographic research uses single-athlete study designs, trend analyses, and statistical process control. Single-athlete designs seek to measure differences in repeated measurements under prescribed conditions, and trend analyses may permit systematic monitoring and prediction of future outcomes. Statistical process control uses control charting and other methods from …

Development And Psychometric Evaluation Of A Post Exercise Exhaustion Scale Utilising The Rasch Measurement Model, Mark D. Hecimovich, Jeremiah J. Peiffer, Allen G. Harbaugh

Faculty Publications

Objectives: The objective of this study to report on the development and psychometric analysis of a scale to measure post exercise exhaustion.

Design: This study utilised the Rasch measurement model for the psychometric analysis of a new scale aimed at measuring acute onset exhaustion in athletes.

Method: An extensive literature review, feedback from athletes and an expert panel from educators in psychology, sports science and exercise physiology provided feedback on the scale, providing evidence of content validity. A final survey, consisting of the 25 items and completed by three hundred and seventynine athletes (Sport: 187 tri-athletes and 192 cyclists; gender: …

The Mental, Emotional, And Bodily Toughness Inventory (Mebtough) [Survey Instrument], Mick G. Mack, Brian G. Ragan

Faculty Publications

The MeBTough is a 43-item, self-report measure of mental toughness. This one-dimensional scale assesses the mental, emotional, and physical (bodily) dimensions of toughness based on the writings of Loehr (1994). Respondents are asked to indicate how often they experience each item on a 4-point Likert-type scale, ranging from 1 (Almost Never) to 4 (Almost Always). Nine of the items are designed to be reverse-scored. Responses to the 43 items are then summed to obtain a total score that can range from 43 to 172. Higher MeBTough scores indicate higher levels of mental toughness.
