Pressurized Device For Mitigating Atrophy In Soleus During Long-Duration Spaceflight, Ramona Tovar Briones, Kimhab Sor, Breandrea Diaz, Dona Varghese, Benjamin Easter, Hunter Alvis, Brandon R. Rigby

International Journal of Exercise Science: Conference Proceedings

A major concern with long duration spaceflight, skeletal muscle atrophy is most detrimental in lower limb musculature, particularly in muscles critical for proper gait, such as the soleus. The decline of muscle activation and the suppression of sensory input from plantar sole mechanoreceptors can add to the attenuation of skeletal muscle health during spaceflight. More specifically, inhibition of sensory input from sole receptors, such as with gravitational unloading, decreases selective activation, thereby negatively affecting muscle tone and inevitably resulting in lower limb atrophy. PURPOSE: To design, fabricate, and test a specialized boot with an insole that applies oscillating pneumatic …

Food Sensitives In Athletes: Whey More Common Than You May Expect?, Eve M. Clarkson Miss, Brittanie L. Lockard, Ben Garza, Julianne Damico, Terah Ege

International Journal of Exercise Science: Conference Proceedings

Food sensitives, which differ from food allergies, are caused by digestive problems to foods that may lead to symptoms such as bloating, diarrhea, constipation, fatigue, headache, joint pain, and sleep disturbances, among other issues. It is estimated that food sensitivities affect 15-20% of the US population. These are IgG antibody-mediated responses that may develop from a variety of causes such as enzymatic defects in the digestive system. Research suggests that IgG-based tests produce clinically meaningful results that aid in the development of a targeted elimination diet.

International Journal of Exercise Science: Conference Proceedings

Mean arterial pressure (MAP) is either measured with an oscillometric cuff and then systolic (SBP) and diastolic (DBP) blood pressures are estimated from an unknown algorithm; or SBP and DBP are measured via auscultation and MAP calculated using measures of systolic pressure (SBP), diastolic pressure (DBP), and a form-factor (FF; equation: [(SBP-DBP)*FF]+DBP). The typical FF used is 0.33 though others (0.4) have been proposed. Recent work indicates that estimation of aortic MAP via a FF leads to inaccurate values and should therefore be interpreted with caution, whether this is the case for local MAP is unknown. While the implications for …
