TL;DR: New WHO 2020 guidelines on physical activity and sedentary behaviour reaffirm messages that some physical activity is better than none, that more physical Activity is better for optimal health outcomes and provide a new recommendation on reducing sedentary behaviours.

Mitochondrial dysfunction in the elderly: possible role in insulin resistance
Kitt Falk Petersen,Douglas E. Befroy,Sylvie Dufour,James Dziura,Charlotte E. Ariyan,Douglas L. Rothman,Loretta DiPietro,Gary W. Cline,Gerald I. Shulman +8 more
TL;DR: Elderly study participants were markedly insulin-resistant as compared with young controls, and this resistance was attributable to reduced insulin-stimulated muscle glucose metabolism, which supports the hypothesis that an age-associated decline in mitochondrial function contributes to insulin resistance in the elderly.
Journal ArticleDOI
Intramyocellular lipid concentrations are correlated with insulin sensitivity in humans: a 1H NMR spectroscopy study.
Martin Krššák,Falk Petersen K,Alan Dresner,Loretta DiPietro,Suzanne M. Vogel,Douglas L. Rothman,Michael Roden,Gerald I. Shulman +7 more
TL;DR: Results show that intramyocellular lipid concentration, as assessed non invasively by localized 1H NMR spectroscopy, is a good indicator of whole body insulin sensitivity in non-diabetic, non-obese humans.
Journal ArticleDOI
A survey for assessing physical activity among older adults.
TL;DR: It is concluded that the YPAS demonstrates adequate repeatability, and some validity by correlating with several physiologic variables reflecting habitual physical activity, and the value in accurately assessing low intensity activity remains to be established.
