Physiological Profile Of Rural Structural Firefighters In Southeast Georgia, Emily Langford
Physiological Profile Of Rural Structural Firefighters In Southeast Georgia, Emily Langford
Electronic Theses and Dissertations
Many occupational tasks associated with firefighting require a great deal of cardiovascular and muscular demands. However, it is often noted that firefighters throughout the country are not meeting the fitness levels required of the profession. As a result, the proportion of on-duty injury and cardiac death is greater than the general population or similar service professions. Purpose: The purpose of this study was to provide an extensive physiological profile of rural firefighters in southeast Georgia. Methods: Forty firefighters from one department in southeast Georgia underwent a comprehensive health screening, measuring anthropometrics (i.e., height, weight, waist and hip circumference), body …
Investigating The Effects Of Endurance Training On Heart Rate Variability In Female Swimmer Athletes, Joshua G. Beck
Investigating The Effects Of Endurance Training On Heart Rate Variability In Female Swimmer Athletes, Joshua G. Beck
Electronic Theses and Dissertations
It is important for elite endurance athletes to have practical and reliable means of measuring fatigue throughout their training. Variations in Autonomic Nervous System activity (ANS) may provide an effective marker of fatigue and of recovery. ANS control of heart rate is well known to be affected by exercise training, and those adaptations can be determined using measures of heart rate variability (HRV). Previous research has examined the effect of training on HRV and ANS control of heart rate in males, there is a lack of any comprehensive studies that address adaptations in female athletes. Therefore, the purpose of this …
Comparing Hyperhydration Ability Between A Glycerol Solution And A Sodium Solution On Dehydration And Performance In Runners, Stephanie L. Marz
Comparing Hyperhydration Ability Between A Glycerol Solution And A Sodium Solution On Dehydration And Performance In Runners, Stephanie L. Marz
Electronic Theses and Dissertations
The purpose of this study was to examine how inducing hyperhydration with a glycerol solution and a sodium solution prior to exercise influenced performance and hydration status during a moderate set-intensity exercise bout followed by a time-to-exhaustion bout when compared to a control solution containing water only. Six well-trained runners ages 21 to 38 with an average relative VO2 peak of 57 ml/kg/min participated in three trials. Each trial included a 2.5 hour hyperhydration phase where participants ingested a solution containing water, glycerol, or sodium. Following hyperhydration, participants ran for 90 minutes at 65% of their HRR followed by …
