Assessment Of Stabilization And Muscle Recruitment In Amputees Following Sit-To-Stand Transfer, Elizabeth Terran Jones

Health, Human Performance and Recreation Undergraduate Honors Theses

Standing from a seated position is a task of daily living that is essential for independence relying heavily on balance and lower-extremity muscle strength and coordination (Whitney et al., 2005). With age, many once healthy individuals lose this ability and are institutionalized or find themselves reliant on others for care due to the development of balance disorders or loss of muscle mass. The majority of research present today on transitional movements affected by balance disorders, such as the sit-to-stand transition, has been focused on the elderly population. A correlation has been established between the Sit-To-Stand Test and factors such as …

Effect Of Hydration Status On Post-Synaptic Cutaneous Vasodilatory And Sudomotor Responses, Ashley Six

Health, Human Performance and Recreation Undergraduate Honors Theses

"Purpose: Previous research shows dehydration decreases sweating and skin blood flow during heat stress but it is unknown whether these decrements are from pre-synaptic (i.e. central nervous system) or post-synaptic (i.e. sweat gland/blood vessel) alterations. The purpose of this study was to determine whether dehydration affects post-synaptic sweating and skin blood flow responses. We hypothesized that dehydration will negatively affect post-synaptic sweating and both endothelium-dependent and independent vasodilation. Methods: 12 males (age= 25 ± 3 y, height = 178.4 ± 5.1 cm, body mass = 75.9 ± 10.9 kg) participated. 24 h before each trial, subjects were passively heated for …

An Evaluation Of Select Physical Activity Exercise Classes (Pex) On Bone Mineral Density, Tori Michelle Stone

UNLV Theses, Dissertations, Professional Papers, and Capstones

INTRODUCTION: According to the National Institute of Health consensus, Osteoporosis causes premature disability in approximately 44 million people (National Institute of Health [NIH], 2001), 80% of this population being women (Ulrich, Georgiou, Gillis, & Snow, 1999). This chronic disease causes 1.5 million fractures annually, 700,000 occurring at the spine (NIH, 2001). One prevention technique developed in recent years is to build a high peak bone mass during growth and in young adult life (Almstedt, Canepa, Ramirez, & Shoepe, 2011). Several publications positively correlate an increase in BMD with increased amounts of exercise. Bone mineral density can be observed through DEXA …
