We believe the IJES, with its emphasis on engaging undergraduate and graduate students in research and scholarly activity, is a valuable resource for promoting the higher-order critical …

The Effects Of Acute Hypoxia On Marksmanship, Chelsea Mary Moore

Human Movement Studies & Special Education Theses & Dissertations

Expeditionary warfighters in the military have the responsibility of being ready to deploy on short notice to any part of the world and be able to effectively complete their mission even if deployed to altitude. Studies demonstrate that altitude can significantly effect heart rate, ventilation rate, arterial oxygen saturation (SaO2) and cognition. Decrements in these areas could lead to a reduction in shooting accuracy. Only two studies have looked at the effects of marksmanship at various altitudes and their results are inconclusive. This study evaluated the effects of acute hypoxia on marksmanship and the effect of a physical exertion task …

Exercise is an effective countermeasure to age related loss of muscle, but may be difficult in elderly patients with complex functional limitations. Whole body vibration (WBV) is a novel tool used to stimulate the neuromuscular system; research indicates it may improve strength, power, and balance in many populations. Purpose: The purposes of this study were to determine if WBV training is feasible in a skilled nursing facility and if standard of care (SOC) with augmented WBV …

Timed Up-And-Go Scores Are Associated With Balance But Not Lower-Extremity Force Production In Elderly Skilled Nursing Facility Patients, Christopher Barnett, Kai Williams, Chris Goldstraw, Sheila Kellagher, Steven Tham, William E. Amonette

International Journal of Exercise Science: Conference Proceedings

Aging is associated with numerous deleterious muscular, skeletal, and neurologic adaptations that may result in functional performance decrements. These decrements are accelerated during periods of unplanned physical inactivity (e.g. hospitalization). Reductions in gait velocity are well documented in the elderly and may result from fear of falling, poor balance, or inability to accelerate because of reduced ground reaction force capabilities. Purpose: To determine if timed up-and-go scores were related to balance or lower extremity force production in skilled nursing facility patients. Methods: Data were collected on 40 patients (77.1±1.4y; 164.2±1.7cm; 75.3±3.3 kg) in an inpatient skilled nursing facility. The 15 …
