1. Ross, Samantha M. Motor Skill Proficiency, Performance and Participation in Children with Physical Disabilities.

Degree: MS, Exercise and Sport Science, 2015, Oregon State University

Background: Mastery of fundamental motor skills (FMS) in childhood is proposed to facilitate participation in physical activity (PA) opportunities, through context-specific application of FMS (Clarke & Metclafe, 2002; Stodden et al., 2008). Children with disabilities impacting motor skill development thus are at greater risk for low PA participation. Evidence indicates significantly lower levels of physical activity among children with physical disabilities compared to peers (Law et al., 2006). However, only a few studies have examined the direct association between this participation discrepancy and FMS within this population, (e.g. Capio, Sit, Abernethy, & Masters, 2012) and the influence of FMS performance during activity on this pathway has not been systematically examined. Purpose: To identify underlying mechanisms for low PA participation relative to motor skill development in children with physical disabilities. Specifically, the mediating effect of motor skill performance on the relationship between FMS proficiency and PA participation level was examined. Methods: Ten children with disabilities were assessed around one time-point in FMS proficiency, FMS performance during a structured activity opportunity, and PA levels, as measured by accelerometry and direct observation. The mediation model was statistically tested using the ordinary least squares approach (Hayes, 2013). Results: PA level, as measured through direct observation, was significantly accounted for by the effect of motor skill proficiency through motor skill performance (95% CI [0.001 - 0.009]). Conclusion: Findings lend initial evidence that among children with physical disabilities observed during a structured PA opportunity, proficiency in motor skills influences rate of skill use, which in turn facilitates greater observed PA levels. Knowledge of this indirect pathway to participation has implications for PA promotion strategies and contributes to the broader discussion of the impact of disability on participation.

2. Brier, Julie A. Identifying Threshold Values of Accelerometer-Determined Moderate-to-Vigorous Physical Activity that Correspond to Self-Reported Compliance to the 2008 Physical Activity Guidelines for Americans : National Health and Nutrition Examination Survey 2003-2006.

Degree: MS, Exercise and Sport Science, 2016, Oregon State University

Current public health guidelines for physical activity (PA) were primarily formulated using evidence collected from a series of prospective cohort epidemiological investigations that measured self-reported PA. In light of this observation, and the known discordance between self-reported and objectively-monitored PA, it remains common for researchers to assess compliance to current PA guidelines (≥ 150 minutes/week of an equivalent combination of moderate- and vigorous-intensity PA [MV2PA]) using objective-monitoring methods such as accelerometer-determined PA. However, investigations seeking to calibrate accelerometer-determined PA against self-reported compliance to current PA guidelines are scant within the extant literature. Calibration of objective-monitoring methods, such as accelerometer-determined PA, may prove fruitful in mitigating the discordance between self-reported and accelerometer-determined PA, while also providing compliance estimates for PA that better reflect a population’s associated health risks. Therefore, the purpose of this study was to identify optimal accelerometer-determined thresholds of MV2PA that correspond to 150 minutes/week of self-reported MV2PA outlined in the current 2008 Physical Activity Guidelines for Americans (PAGA). This study was a secondary analysis of 4,784 adults (18-64 years) from the 2003-2006 NHANES who provided ≥ 4 valid days of accelerometer data. Receiver operating characteristic (ROC) curves were used to identify accelerometer-determined thresholds of weekly MV2PA corresponding to self-reported compliance to the 2008 PAGA. MV2PA in modified 10-minute bouts and total MV2PA were significant predictors of self-reported compliance to the 2008 PAGA (both p < 0.001). Optimal thresholds of accelerometer-determined MV2PA predicting self-reported compliance to the 2008 PAGA were 13.00 ± 1.69 minutes/week in modified 10-minute bouts and 122.30 ± 4.62 minutes/week in total (no bout requirement). However, levels of sensitivity and specificity associated with ROC curve analyses were low (all < 70%). Construct validity analyses revealed that self-reported compliance to the 2008 PAGA was only favorably associated with one cardiometabolic biomarker (glycated hemoglobin, p = 0.003). Conversely, compliance to the 2008 PAGA assessed using the newly identified accelerometer-determined MV2PA threshold in modified 10-minute bouts (≥ 13.0 minutes/week of MV2PA) was favorably associated with 5 biomarkers (glycated hemoglobin, high-density lipoprotein [HDL], systolic blood pressure [SBP], waist circumference, and body mass index [BMI]; all p < 0.05) and 2 chronic diseases (hypertension and obesity; all p < 0.01). Similarly, compliance to the 2008 PAGA assessed via total accelerometer-determined MV2PA (≥ 122.3 minutes/week of MV2PA; no bout requirement) was favorably associated with 6 biomarkers (glycated hemoglobin, fasting plasma glucose, triglycerides, SBP, waist circumference, and BMI; all p < 0.05) and 4 chronic diseases (hypertension, obesity, impaired fasting glucose, and diabetes… Advisors/Committee Members: Schuna, John M.
