Examining The Effects Of Exercise-Induced, Physical Stress Overtraining On Stress Biomarkers In Adolescent, C57bl/6 Mice, Curtis Scotty Davis Jan 2022

Examining The Effects Of Exercise-Induced, Physical Stress Overtraining On Stress Biomarkers In Adolescent, C57bl/6 Mice, Curtis Scotty Davis

Theses, Dissertations and Capstones

Exercise has long been established as a therapeutic modality to improve health and related physical fitness, sports performance, and injury/risk reduction in both adults and adolescents (Haff & Triplett, 2015; Kaminsky, 2010). Nonetheless, there is a lack of research investigating the negative effects of exercise overstress (i.e., overtraining syndrome) in these populations, particularly adolescents (Brenner & American Academy of Pediatrics Council on Sports Medicine and Fitness, 2007; Matos & Winsley, 2007). The objective of this study was to examine hormone biochemical markers, anthropometric markers, and behavioral traits, which are associated with overtraining syndrome, in adolescent C57BL/6 mice. A total of …


Biomarkers Of Inflammation In Heart Failure Patients With Reduced And Preserved Ejection Fractions: Multi-Ethnic Study Of Atherosclerosis, Michelle Lynne Stone Jan 2020

Biomarkers Of Inflammation In Heart Failure Patients With Reduced And Preserved Ejection Fractions: Multi-Ethnic Study Of Atherosclerosis, Michelle Lynne Stone

UNF Graduate Theses and Dissertations

Purpose Examine the relationships between high-sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6), and soluble tumor necrosis factor-α receptor-1 (sTNF-R1) and the cumulative risk of heart failure with reduced (HFrEF) and preserved (HFpEF) ejection fractions in a diverse, population-based sample. Methods Study sample included 6,814 adult (45-84 years of age) men and women who participated in the Multi-Ethnic Study of Atherosclerosis and were free of cardiovascular disease at baseline. Cox regression was used to calculate the hazard ratios (HR) associated with elevated baseline hs-CRP (> 3-10 mg/L), IL-6 (> 75th percentile) and sTNF-R1 (> 75th percentile) and risk of overall …


An Analysis Of The Physiological And Psychological Wellbeing Of Irish Naval Service Personnel, Cliodhna Sargent Jan 2017

An Analysis Of The Physiological And Psychological Wellbeing Of Irish Naval Service Personnel, Cliodhna Sargent

Theses

Whilst all military cohorts have been seen to experience both physiological and psychological stressors during occupational duties, the naval service experience different stressors due the prolonged periods of time spent at sea. Research has analysed some of these stressors however many them have focused on how individuals are affected because of time spent in combat zones. The Irish Naval Service (INS) is an organisation under the Irish Defence Forces organisation and as such many of its physiological and psychological assessment procedures have come from the Defenee Forces. Very limited researeh has been carried out in relation to the INS as …


Power Output And Loads On The Lumbar Vertebrae During A Power Clean 2016, Joseph Keleher May 2016

Power Output And Loads On The Lumbar Vertebrae During A Power Clean 2016, Joseph Keleher

Master's Theses

The purpose of the present study was to compare the peak resultant torque, shear, and compressive forces acting at the L3/L4 junction of the lumbar vertebrae and the peak power output during 40% one repetition maximum (1RM) and 80% 1RM attempts of the power clean. It was hypothesized that performance of a power clean at 80% 1RM will result in greater peak resultant compressive force, torque and shear force at the L3/L4 junction of the lumbar spine than that of a 40% 1RM attempt. Power cleans at 80% 1RM will also result in higher maximum instantaneous power outputs than that …


Comparison Of Two Different Sprint Interval Training Work-To-Rest Ratios On Acute Metabolic And Inflammatory Responses, Christopher R. Harnish Jan 2014

Comparison Of Two Different Sprint Interval Training Work-To-Rest Ratios On Acute Metabolic And Inflammatory Responses, Christopher R. Harnish

Theses and Dissertations

High intensity exercise is believed to yield greater results on health and human performance than moderate intensity exercise. Extensive research indicates that not only do high-intensity interval training (HIT) and sprint interval training (SIT) produce significant improvements in cardiovascular fitness and disease, they may be more effective at improving long-term metabolic function, including insulin sensitivity (Si), by producing more mitochondria. Moreover, compliance rates for HIT and SIT participation are reported to be the same or better than traditional moderate intensity exercise. Because lack of time is often cited as major hindrance to exercise participation, SIT is also seen as a …
