Disuse-Induced Bone Loss Is Impacted By Age, Anne M. Anderson, Corinne Metzger, Susan Bloomfield Feb 2017

Disuse-Induced Bone Loss Is Impacted By Age, Anne M. Anderson, Corinne Metzger, Susan Bloomfield

International Journal of Exercise Science: Conference Proceedings

Bone is a dynamic tissue that responds and adapts to stresses and strains. When bones are more frequently subjected to mechanical loads (i.e. weight-bearing exercise), bones adapt by increasing in bone mass. The opposite occurs when the bones are not regularly exposed to mechanical loads leading to a loss of bone mass and increased risk of fracture. Patients on extended bed rest or astronauts in long duration spaceflight space experience disuse-induced bone loss. PURPOSE: The purpose of this experiment was to see if young (growing) and old (skeletally mature) rats respond differently to short term disuse. We hypothesized young rats …

International Journal of Exercise Science: Conference Proceedings

The defining feature of cancer cachexia is extensive weight loss and skeletal muscle atrophy. It is clinically important because cachexia reduces patient survival, results in functional impairment, and is estimated to be directly responsible for 20-40% of cancer deaths. Unfortunately, no clinical therapy exists and therefore, it is important to understand the molecular mechanisms responsible for rapid muscle wasting. Compared to limb muscles, the diaphragm is relatively understudied in cancer cachexia, but is likely to be adversely affected because cachexia is a systemic disease. Wasting of the primary inspiratory muscle may result in difficulty breathing and inability to adjust minute …

A New Way To Measure Physical Exertion: The Compensatory Reserve, Kristen Lye, Sarah Fritzsche, Casi Helbig Feb 2017

A New Way To Measure Physical Exertion: The Compensatory Reserve, Kristen Lye, Sarah Fritzsche, Casi Helbig

International Journal of Exercise Science: Conference Proceedings

During periods of physiological stress, such as hemorrhage, the body is able to deploy multiple mechanism of compensation such as changes in heart rate and vascular tone. These compensatory mechanisms allow the body to maintain blood flow, and therefore oxygenation to major organs. The degree to which these compensatory mechanisms are active in simulated hemorrhage are detectable in arterial waveforms and quantifiable by the compensatory reserve index (CRI). PURPOSE: Because physical exertion also activates multiple compensatory mechanisms, it was hypothesized that CRI could be used to quantify physical exertion. METHODS: Healthy human subjects (N = 6) performed a …
