Autor: Vaka Rognvaldsdottir, Robert J Brychta, Soffia M Hrafnkelsdottir, Kong Y Chen, Sigurbjorn A Arngrimsson, Erlingur Johannsson, Sigridur L Guðmundsdottir

Publikováno v: PLoS ONE, Vol 15, Iss 5, p e0229114 (2020)

BACKGROUND:Sleep and physical activity are modifiable behaviors that play an important role in preventing overweight, obesity, and metabolic health problems. Studies of the association between concurrent objective measures of sleep, physical activity

Publikováno v: PLoS ONE, Vol 13, Iss 4, p e0196286 (2018)

Few studies have explored the potential interrelated associations of screen time and physical activity with mental health in youth, particularly using objective methods. We examined cross-sectional associations of these variables among Icelandic adol

Identifying bedrest using 24-h waist or wrist accelerometry in adults.

Autor: J Dustin Tracy, Sari Acra, Kong Y Chen, Maciej S Buchowski

Publikováno v: PLoS ONE, Vol 13, Iss 3, p e0194461 (2018)

OBJECTIVES:To adapt and refine a previously-developed youth-specific algorithm to identify bedrest for use in adults. The algorithm is based on using an automated decision tree (DT) analysis of accelerometry data. DESIGN:Healthy adults (n = 141, 85 f

Autor: Alexander H. Choi, Melanie Delgado, Kong Y. Chen, Stephanie T. Chung, Amber Courville, Sara A. Turner, Shanna Yang, Kayla Airaghi, Irene Dustin, Patrick McGurrin, Tianxia Wu, Mark Hallett, Debra J. Ehrlich

Publikováno v: BMC Neurology, Vol 24, Iss 1, Pp 1-19 (2024)

Abstract Background A ketogenic diet (KD) may benefit people with neurodegenerative disorders marked by mitochondrial depolarization/insufficiency, including Parkinson’s disease (PD). Objective Evaluate whether a KD supplemented by medium chain tri

Separating bedtime rest from activity using waist or wrist-worn accelerometers in youth.

Autor: Dustin J Tracy, Zhiyi Xu, Leena Choi, Sari Acra, Kong Y Chen, Maciej S Buchowski

Publikováno v: PLoS ONE, Vol 9, Iss 4, p e92512 (2014)

Recent interest in sedentary behavior and technological advances expanded use of watch-size accelerometers for continuous monitoring of physical activity (PA) over extended periods (e.g., 24 h/day for 1 week) in studies conducted in natural living en

Association of sedentary time with mortality independent of moderate to vigorous physical activity.

Autor: Annemarie Koster, Paolo Caserotti, Kushang V Patel, Charles E Matthews, David Berrigan, Dane R Van Domelen, Robert J Brychta, Kong Y Chen, Tamara B Harris

Publikováno v: PLoS ONE, Vol 7, Iss 6, p e37696 (2012)

BackgroundSedentary behavior has emerged as a novel health risk factor independent of moderate to vigorous physical activity (MVPA). Previous studies have shown self-reported sedentary time to be associated with mortality; however, no studies have in

Estimation of daily energy expenditure in pregnant and non-pregnant women using a wrist-worn tri-axial accelerometer.

Autor: Vincent T van Hees, Frida Renström, Antony Wright, Anna Gradmark, Michael Catt, Kong Y Chen, Marie Löf, Les Bluck, Jeremy Pomeroy, Nicholas J Wareham, Ulf Ekelund, Søren Brage, Paul W Franks

Publikováno v: PLoS ONE, Vol 6, Iss 7, p e22922 (2011)

Few studies have compared the validity of objective measures of physical activity energy expenditure (PAEE) in pregnant and non-pregnant women. PAEE is commonly estimated with accelerometers attached to the hip or waist, but little is known about the

Beyond day and night: The importance of ultradian rhythms in mouse physiology

Autor: Vojtěch Škop, Naili Liu, Cuiying Xiao, Emma Stinson, Kong Y. Chen, Kevin D. Hall, Paolo Piaggi, Oksana Gavrilova, Marc L. Reitman

Publikováno v: Molecular Metabolism, Vol 84, Iss , Pp 101946- (2024)

Our circadian world shapes much of metabolic physiology. In mice ∼40% of the light and ∼80% of the dark phase time is characterized by bouts of increased energy expenditure (EE). These ultradian bouts have a higher body temperature (Tb) and therm
