Feasibility And Efficacy Of A Recess-Based Combined Fitness Intervention On Cognition And Academic Performance In Elementary School Children, Christine St Laurent Jul 2019

Feasibility And Efficacy Of A Recess-Based Combined Fitness Intervention On Cognition And Academic Performance In Elementary School Children, Christine St Laurent

Doctoral Dissertations

Youth physical activity and fitness have been reported to influence cognition and academic related outcomes. Despite the potential benefits of muscular fitness, few intervention studies have examined the impact of an intervention that has incorporated both cardiorespiratory and muscular fitness training on cognition and academic performance in children. Previous studies have mainly been implemented either during the school day or immediately after-school. Although recess may be an ideal time to promote physical activity because it does not compete with other academic demands, it has been an understudied setting. Therefore, the purpose of this dissertation project was to examine the feasibility ...


Development And Cross-Validation Of A Cadence-Based Metabolic Equation For Walking, Christopher C. Moore Jul 2019

Interfacing Continuous Measurement Of Glucose And Physical Activity To Predict Glycemic Control In Individuals With Type 2 Diabetes, Jennifer Blankenship Mar 2017

Interfacing Continuous Measurement Of Glucose And Physical Activity To Predict Glycemic Control In Individuals With Type 2 Diabetes, Jennifer Blankenship

Doctoral Dissertations

Physical activity is a cornerstone in the management of hyperglycemia and risk of cardiovascular disease in type 2 diabetes (T2D). However, the dose response relationship between physical activity and glucose regulation is not well defined. The overall goal of this dissertation was to assess the magnitude and timing of changes of daily glucose concentrations in response to continuous and intermittent light physical activity in T2D. Through utilizing continuous glucose monitors (CGM) and physical activity monitoring concurrently, we were able to assess the glycemic impact of physical activity and sedentary behavior in the free-living environment.

Study 1 aimed to examine the ...


Feasibility Of A Combined Physical Activity And Sleep Education Intervention For Girls Living In A Low Socioeconomic Status Urban Community, Cory J. Greever Jul 2016

Feasibility Of A Combined Physical Activity And Sleep Education Intervention For Girls Living In A Low Socioeconomic Status Urban Community, Cory J. Greever

Doctoral Dissertations

Declining sleep duration and poor sleep quality is a public health epidemic disproportionately effecting elementary age girls living in low socioeconomic status urban communities. The Girls Dancing and Sleeping for Health (Girls DASH) program was designed to test the feasibility, acceptability, and efficacy of a combined physical activity and sleep education program in this population. In combination with baseline data from a previously conducted intervention in elementary age urban girls living in a low SES community in Springfield, MA, results from a cross-sectional analysis indicated that greater screen time was positively associated with parental reports of child’s sleep quality ...


Effects Of Conjugated Linoleic Acid (Cla) On Skeletal Muscle Metabolism, Yoo Kim Nov 2015

Effects Of Conjugated Linoleic Acid (Cla) On Skeletal Muscle Metabolism, Yoo Kim

Doctoral Dissertations

Although it is well known that increased physical activity can help reduce incidences of obesity, physical activity can be influenced by complex issues, making it difficult to use universal means to control obesity. Recent discoveries of the effects of exercise at the cellular level opened up the unique opportunity to develop compounds with ‘exercise-like’ effects. In fact, CLA has been shown to promote voluntary activity and endurance capacity in mice. Thus, the purpose of these studies is to determine the mechanisms of conjugated linoleic acid on muscle metabolism via the modulation of biochemical events including mitochondrial biogenesis and the alternation ...


Impact Of A Preschool Workplace Intervention On Classroom Teachers’ Physical Activity Levels And Quality Of Life, Ogechi O. Nwaokelemeh Aug 2015

Impact Of A Preschool Workplace Intervention On Classroom Teachers’ Physical Activity Levels And Quality Of Life, Ogechi O. Nwaokelemeh

Doctoral Dissertations

PURPOSE: To examine the feasibility and efficacy of a three-month, cluster-randomized workplace PA intervention on PA levels and wellbeing measures in preschool classroom teachers. METHODS: Ten preschool centers were randomized into two groups; short-bouts of structured PA (SBS-PA, n=5) or traditional unstructured PA (TRAD-PA, n=5). The SBS-PA intervention consisted of 10-minute structured, teacher-led PA routines implemented within the classroom setting, followed by 20 minutes of unstructured playtime. The TRAD-PA intervention consisted of supervised 30-minute of unstructured free playtime. Both interventions were implemented during the morning and afternoon designated gross-motor playtime for 30 min/session, five days/week for ...


The Role Of Sleep Timing On Diet Quality And Physical Activity Among College-Aged Women Participating In The University Of Massachusetts Vitamin D Status Study, Deniz Azarmanesh Nov 2014

The Role Of Sleep Timing On Diet Quality And Physical Activity Among College-Aged Women Participating In The University Of Massachusetts Vitamin D Status Study, Deniz Azarmanesh

Masters Theses

Overweight and obesity are risk factors for various chronic diseases. Sleep has been associated with overweight and obesity. One potential mechanism by which sleep may lead to overweight and obesity is through positive energy balance (i.e. energy intake exceeding expenditure). There are few studies examining the impact of sleep timing (onset and wake time) on diet and exercise. In a cross sectional study, we examined associations between sleep timing and diet quality, and in separate models, between sleep timing and meeting the 2008 Physical Activity Guidelines for Americans among the participants of the UMass Vitamin D Status Study. A ...


The Influence Of Free-Living Activity And Inactivity On Health Outcomes And Responsiveness To Exercise Training, Sarah Kozey Keadle May 2012

The Influence Of Free-Living Activity And Inactivity On Health Outcomes And Responsiveness To Exercise Training, Sarah Kozey Keadle

Open Access Dissertations

On average, starting an exercise training program decreases one’s risk for chronic disease. However, there is remarkable individual variability in physiologic responses to exercise training. The activity and inactivity during the remaining 95% of the day (when the individual is not training) is rarely considered. The overall objective of this dissertation was to apply validated sedentary behavior (SB) and physical activity (PA) measurement techniques during an exercise training study to determine if time spent in SB and PA outside of training influences the physiological response to training. Twenty subjects participated in a pilot study to determine the feasibility of ...


"A"-Kids: Activity Kcal Intervention Daily Study. Effects Of 100-Kcal Daily Energy Expenditure On Total Moderate-To-Vigorous Physical Activity In 3rd Grade Children, Cheryl A. Howe Feb 2010

"A"-Kids: Activity Kcal Intervention Daily Study. Effects Of 100-Kcal Daily Energy Expenditure On Total Moderate-To-Vigorous Physical Activity In 3rd Grade Children, Cheryl A. Howe

Open Access Dissertations

A selection of common children’s games were measured in a laboratory-based study to be enjoyable and to elicit sufficient physical activity energy expenditure (PAEE) in 3rd grade children to combat the purported chronic energy surplus of childhood obesity (~100 kcal.day-1). PAEE during the games was similar for boys and girls, yet overweight children expended greater PAEE relative to body weight than healthy weight children. During a subsequent simulated recess program, the enjoyment declined over the 10-session program with no significant decline in PAEE. Using the enjoyable games of known energy cost in a structured recess program for 9 ...
