Racial Differences In Self-Efficacy Expectations For Exercise, Selena P. Smith Dec 2013

Racial Differences In Self-Efficacy Expectations For Exercise, Selena P. Smith

Honors Theses

This project examined the link between race and self-efficacy. Self-efficacy pertains to an individual’s confidence in ability to complete or engage in a particular task or activity (Bandura, 1986). Prior research shows that self-efficacy has a great influence on exercise initiation and adherence (Bandura, 1986; Dishman, 1982; Rodgers and Sullivan, 2001). Research also supports that Caucasians are more likely to participate in exercise than African Americans (Centers for Disease Control and Prevention, 2000).

Participants included 51 females, 31 Caucasians and 20 African Americans, between the ages of 18 and 50 years old. The women were recruited from local fitness gyms, …


Comparative Effects Of Upper Or Lower Body Ergometry To Facilitate Recovery From High-Intensity Combined Arm And Leg Exercise, Benjamin Chad Lyman May 2013

Comparative Effects Of Upper Or Lower Body Ergometry To Facilitate Recovery From High-Intensity Combined Arm And Leg Exercise, Benjamin Chad Lyman

Honors Theses

The purpose of this study was to compare the effects of upper body versus lower body ergometry on blood lactate concentration ([La]) disappearance. Ten individuals (age: 20.6 ± 1.3 yrs, height: 1.72 ± 0.08 m, weight: 66.77 ± 10.42 kg) completed preliminary testing sessions, 3-5 days apart, to determine the power output corresponding with the subject’s onset of blood lactate (OBLA), which for the purposes of this study is considered the subject’s lactate threshold (LT), for leg ergometry (LTL) and arm ergometry (LTA). Participants then returned to the laboratory on three separate occasions to complete the …


A Quantitative Comparison Of Energy Expenditure Between Exergames And Physical Activity Recommendations, Dalton A. Newell May 2013

A Quantitative Comparison Of Energy Expenditure Between Exergames And Physical Activity Recommendations, Dalton A. Newell

Honors Theses

The purpose of this study was to analyze the energy expenditure associated with two commercially available exergames (Dance Dance Revolution 2 (DDR2) and Wii Sports 1: Tennis) and evaluate whether or not this type of activity could be used as a means to obtain the recommended amount of physical activity. Thirty individuals (15 males, 15 females) participated in the study. Each participant attended 3 sessions: a 30-min familiarization session and 2, 45-min testing sessions. During each testing session, participants played one of the exergames for 30 min while continuously being measured for oxygen consumption (VO2), respiratory exchange ratio …


Investigations Toward Tunability Of Mechanical, Thermal, And Impact Properties Of Thiol-Ene Networks For Novel High Energy Absorbing Materials, Olivia Devon Mcnair May 2013

Investigations Toward Tunability Of Mechanical, Thermal, And Impact Properties Of Thiol-Ene Networks For Novel High Energy Absorbing Materials, Olivia Devon Mcnair

Dissertations

The UV polymerization of thiols with electron rich alkenes is a highly resourceful reaction that has been utilized by scientists within various disciplines to produce an even more versatile display of applications. This dissertation focuses on a newer application, thiol-ene network (TEN) materials for energy absorption devices. TEN networks display a host of positive polymer properties such as low stress, high optical clarity and uniformity, but they also suffer from unfavorable mechanical properties such as low toughness and elongation at break. The poor mechanical properties demonstrated by TENs prohibit them as choice materials for applications requiring thicker material forms, including …
