Prediction of Non-Resting Energy Expenditure using Accelerometry
… valid, objective, inexpensive, and easy to use. Accelerometry, along with validated prediction equations for resting energy requirements, may provide an opportunity to fill this void. Twenty weight stable adults (12 female, 8 male) who recently participated in a controlled feeding study comprised …

Whole-body biomechanical load monitoring from accelerometry in team sports
… thesis was therefore to explore if body-worn accelerometry can be used for whole-body biomechanical load monitoring in team sports. The first study of this thesis showed that although a linear relationship exists between body-worn accelerometry (e.g. from GPS integrated accelerometers) and …

The physical activity status and patterns in adults with Cerebral Palsy - an accelerometry study
One of the most common causes of physical disability acquired during childhood is cerebral palsy (CP). Due to improvements in medical care over the past decades, almost all children with CP survive into adulthood nowadays. In addition, based on a stable incidence rate and longevity of individuals …

Sedentary Behavior In Preschool Children: Studies of Reliability, Level, and Effect of Objectively Measured Sedentary Behavior
… preschool children. All three studies employed accelerometry as an objective measure of sedentary behavior. </p> <p> In study one, the accelerometry-derived sedentary behavior was summarized using three different cutpoints (< 37.5 cts/15s, <200 cts /15s, and <373 cts /15s). Across different …

Effect of a structured exercise program on physical activity patterns and assessing relationships between accelerometry and strength and running performance characteristics in male, college students
The primary purpose of this study was to determine the effect of a supervised exercise training program on physical activity (PA) patterns. A secondary objective of the study was to determine if accelerometers can predict variables associated with strength and running performance. A total of 79 …

Assessment of Real-World Upper Limb Activity in Adults with Chronic Stroke
… stroke, and to develop and validate a novel, accelerometry-derived assessment methodology to quantify motor performance.Using wrist-worn accelerometry, we characterized duration of upper limb (UL) activity that occurred in everyday environments (i.e. real-world activity) as an index of motor …

Examination of accelerometer reactivity among children, adolescents, and adults: Implications for influencing physical activity estimates, proportion meeting physical activity guidelines, and associations with health outcomes
… measuring PA with an objective measure, such as accelerometry. Reactivity is a behavior change by the participant due to the fact that he/she is aware that they are being monitored. The implications of accelerometer reactivity are such that, if present, then accelerometer-determined PA estimates …
