The Role Of Spine In Causing Lameness In Horses, Raja Zabeeh Ullah Khan

English Language Institute

Lameness is one of the most important problems of horses. It influences all communities who keep horses. Recent studies have shown the significance of spinal muscles and vertebrae in inducing lameness in horses. The field has not been explored much and requires application of biomechanics to define the role of spine in inducing lameness in horses. This presentation highlights the importance of spine in inducing lameness in horses by relating the solution with biomechanics.

Acute Physiological Responses To Arm-Cranking With Blood Flow Restriction, Benjamin Cockfield

Dissertations, Master's Theses and Master's Reports

Physiological responses to aerobic blood flow restriction exercise (BFR) are well documented for lower-body exercise but not upper-body exercise. I evaluated cardiorespiratory (heart rate, VO2, RER, ventilation), metabolic (tissue saturation, deoxyhemoglobin concentrations), and perceptual (effort, pain) responses to arm cranking with BFR at varying arterial occlusion pressures (AOP). Ten adults performed 4 intermittent arm cranking protocols (6x2-min, 1-min recovery): 1) low load (LL) – 40%VO2peak and 0% AOP; high load (HL) – 80%VO2peak and 0% AOP; (BFR50) – 40%VO2peak with 50% AOP; (BFR70) – 40%VO2peak with 70% AOP. Heart rate, RER, and ventilation, were higher with BFR compared to LL …

Metabolic And Cardiovascular Marker Alterations During Critical Training In Wildland Firefighters, Shae Gurney

Graduate Student Theses, Dissertations, & Professional Papers

Introduction: Wildland firefighters (WLFFs) are confronted with numerous physical and mental stressors. Pre-fire season includes an intense 2-week critical training (CT) period; a preparatory phase of multiple activities that can result in injury, illness, and rhabdomyolysis. The purpose of this study was to identify physiologic changes in metabolic, inflammatory, and oxidative stress biomarkers during 2 weeks of CT in WLFFs.

Methods: Eighteen male (29.4 ± 1.1 yr, 182.1 ± 1.6 cm) and three female (26.7  2.6 yr, 169.5  4.2 cm) participants were recruited from a Type I interagency hotshot crew and monitored over their 2-week CT. Fitness was …

Muscle Soreness And Damage During Wildland Firefighter Critical Training, Katherine Sue Christison

Graduate Student Theses, Dissertations, & Professional Papers

Introduction: Wildland firefighters (WLFF) undergo a critical training (CT) period immediately before the firefighting season. The intensity of CT exercise could lead to muscle damage, as previously reported cases of rhabdomyolysis in WLFFs have been documented. This study established the effects of activities performed during a two-week CT period on acute markers of muscle damage in WLFFs.

Methods: 18 male and 3 female Type I Interagency Hotshot WLFFs were studied during a 14-day critical training period. Upper- (US) and lower-body (LS) muscle soreness and daily body weight (BW) scales were collected. Venous blood was collected on Days 1, 4, 8, …
