The Impact Of Exercise In Spaceflight And Microgravity Environments, William Bybee
The Impact Of Exercise In Spaceflight And Microgravity Environments, William Bybee
Mahurin Honors College Capstone Experience/Thesis Projects
Since mankind’s first spaceflight, a significant barricade in reaching distant planets has been the damaging effects of microgravity upon the human body. Effects range from loss in bone mineral density and severe muscle atrophy to autoimmune disorders. The most effective countermeasure of these effects to date is exercise. Implementation of exercise in microgravity is not an easy task, so various specialized equipment must be utilized to effectively administer it. Even with this equipment, exercise as it is currently used does not entirely prevent body systems from undergoing detrimental changes. New modalities and implementations are currently being investigated that may significantly …
The Validity Of Submaximal Exercise Testing In Obese Women, Gabrielle Ringenberg
The Validity Of Submaximal Exercise Testing In Obese Women, Gabrielle Ringenberg
Mahurin Honors College Capstone Experience/Thesis Projects
Background: Submaximal exercise tests use heart rate responses to low-to-moderate intensity activity in order to predict cardiorespiratory fitness (VO2max). Currently used tests may be inappropriate for obese populations as obese women have altered heart rate responses to exercise. The purpose of this project is to test the validity of the Modified Bruce Protocol submaximal treadmill test in obese women. Methods: Normal-weight (NWG) and obese women (OBG) completed the Modified Bruce submaximal treadmill test (to predict VO2max using previously validated equations) and a maximal graded exercise test on a treadmill using the Standard Bruce Protocol (to obtain an …
