Description
The health benefits of physical activity are widely accepted. Emerging research also indicates that sedentary behaviors can carry negative health consequences regardless of physical activity level. This dissertation explored four projects that examined measurement properties of physical activity and sedentary behavior monitors. Project one identified the oxygen costs of four other care activities in seventeen adults. Pushing a wheelchair and pushing a stroller were identified as moderate-intensity activities. Minutes spent engaged in these activities contribute towards meeting the 2008 Physical Activity Guidelines. Project two identified the oxygen costs of common cleaning activities in sixteen adults. Mopping a floor was identified as moderate-intensity physical activity, while cleaning a kitchen and cleaning a bathtub were identified as light-intensity physical activity. Minutes spent engaged in mopping a floor contributes towards meeting the 2008 Physical Activity Guidelines. Project three evaluated the differences in number of minutes spent in activity levels when utilizing different epoch lengths in accelerometry. A shorter epoch length (1-second, 5-seconds) accumulated significantly more minutes of sedentary behaviors than a longer epoch length (60-seconds). The longer epoch length also identified significantly more time engaged in light-intensity activities than the shorter epoch lengths. Future research needs to account for epoch length selection when conducting physical activity and sedentary behavior assessment. Project four investigated the accuracy of four activity monitors in assessing activities that were either sedentary behaviors or light-intensity physical activities. The ActiGraph GT3X+ assessed the activities least accurately, while the SenseWear Armband and ActivPAL assessed activities equally accurately. The monitor used to assess physical activity and sedentary behaviors may influence the accuracy of the measurement of a construct.

Description
The purpose of this dissertation was to document the teaching practices and underlying intentions of teachers in a Waldorf early childhood program in relationship to integrative movement and its connections to learning for the kindergarten through grade three learner. Current concerns about unhealthy sedentary lifestyles and the decreasing emphasis on physical activity/movement in public schools are growing. This dissertation explores current educational research related to the effects of movement on cognitive processing and the potential effects of movement on learning, particularly in a Waldorf-based early childhood program in which movement is integrated into all aspects of learning (including all academic subjects). This dissertation includes a literature review of current research and theory, and a qualitative micro-ethnographic case study of a Waldorf-based early childhood program that involved teacher observations and interviews. Key findings: the Waldorf-based early childhood program provided practical methods for (1) encouraging various modes of free play intended to enhance a child's physical, social/emotional and academic development, (2) integrating teacher-led movements into the daily curriculum, (3) utilizing movement to aid cognitive processing and prepare students for more sedentary academic work, (4) integrating remedial work into the daily classroom curriculum, and (5) utilizing intentional movement to help a child learn to embody stillness as a means of focusing attention and energy. Movements integrated into the curriculum by the teachers created observable positive effects on the students: eagerness to participate, recall, extending focus and attention, and creating social awareness and cooperation. Conclusions: (1) Waldorf-based education programs may provide practical examples and theoretical perspectives relevant to the creation of an integrated and comprehensive movement-based curriculum for the early childhood learner, and (2) The Waldorf teachers studied provide a counter-position to early childhood teaching practices that utilize movement as a break from sedentary learning. This study revealed the effects of imposing or integrating stillness into a movement-rich curriculum. Future recommendations include more comprehensive research on Waldorf-based educational programs and educational research that reaches beyond movement's potential positive or negative effect on a student's academic progress to study in more depth how and why movement impacts learning for the young child.

Description
Sedentary behavior has recently been recognized as a widespread, independent risk factor for increased morbidity and mortality from chronic conditions including diabetes, cardiovascular disease, and cancer. Midlife women (age 40-64) are known to have high levels of sedentary behavior and corresponding cardiovascular disease risk. Currently, little is known about mechanisms involved in reducing and maintaining reductions to sedentary behavior in midlife women. Theory-based nursing interventions are needed which reflect process, personal meaning, person-environment interaction, and incorporate a strength-based perspective. Wellness Motivation Theory guided the research, conceptualizing behavioral change processes within culturally and environmentally relevant contexts, while recognizing bidirectional influences of personal and environmental factors on behavioral patterns. The Wellness Motivation Theory addresses social support and norms, community and material resources that influence behavioral choices, individual motivation and goals, and the behavioral change processes of self-knowledge, motivational appraisal, and self-regulation. A qualitative descriptive approach was used to explore social contextual resources and behavior change processes leading to action as decreasing sedentary time in midlife women. The maximum variation sample included 31 midlife women, employees of Arizona State University. Participants attended a one-hour focus group to discuss their experiences with sedentary behavior, and their efforts to sit less and move more. Midlife women characterized social support as: Raising Me Up, Timing Time and Walking and Talking. Support from contextual resources reflected themes of Seeking Place, Stepping Up, and Walking the Talk. Women experienced self-knowledge as Envisioning the Future, Taking Inventory, and Considering Possibles. Motivational appraisal was characterized as Reevaluating Priorities, Wayfinding, and Going All In. Self-regulation was reflected as Recounting Benefits, Keeping On Track, and Creating New Ways. A deeper understanding of motivational processes central to reducing sedentary behavior in midlife women fosters identification of leverage points for future theory-based intervention research which provides primary prevention opportunities to lower cardiovascular disease risk, and promote successful aging.
