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 …
The Effects Of High-Intensity Interval Training And 28 Days Of [Beta]-Hydroxy-[Beta]-Methybutyrate Supplementation On Measures Of Aerobic Power And Metabolic Thresholds, Edward Robinson
Electronic Theses and Dissertations
Purpose: To examine the effects of 28 days of β-hydroxy-β-methylbutyrate free acid (HMB) and high-intensity interval training (HIIT) on maximal oxygen consumption (VO2peak), ventilatory threshold (VT), respiratory compensation point (RCP) and time to exhaustion (Tmax) in collegeaged men and women. Methods: Healthy men and women (n=34, age and VO2peak= 22.7+3.1yr and 39.3+5.0 mL. kg-1.min-1, respectively) participated in this study. All participants completed a series of tests prior and subsequent to treatment. A maximal oxygen consumption test was performed on a cycle ergometer to assess VO2peak, Tmax, VT, and RCP. The peak power output (Ppeak), power at VT (PVT) and power …
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 …
