TLDR
There was a large variability in accelerometer output and their validity to assess daily physical activity and there is little evidence that adding other physiological measures such as heart rate significantly improves the estimation of energy expenditure.Abstract:
The field of application of accelerometry is diverse and ever expanding. Because by definition all physical activities lead to energy expenditure, the doubly labelled water (DLW) method as gold standard to assess total energy expenditure over longer periods of time is the method of choice to validate accelerometers in their ability to assess daily physical activities. The aim of this paper was to provide a systematic overview of all recent (2007-2011) accelerometer validation studies using DLW as the reference. The PubMed Central database was searched using the following keywords: doubly or double labelled or labeled water in combination with accelerometer, accelerometry, motion sensor, or activity monitor. Limits were set to include articles from 2007 to 2011, as earlier publications were covered in a previous review. In total, 38 articles were identified, of which 25 were selected to contain sufficient new data. Eighteen different accelerometers were validated. There was a large variability in accelerometer output and their validity to assess daily physical activity. Activity type recognition has great potential to improve the assessment of physical activity-related health outcomes. So far, there is little evidence that adding other physiological measures such as heart rate significantly improves the estimation of energy expenditure.read more

Correlates of subjectively and objectively measured physical activity in young adolescents
TL;DR: Measuring MVPA via self-report versus accelerometry produces considerably different results in a sample of young adolescents, and future studies should use caution when selecting outcome measures if the intent is to identify modifiable correlates of MVPA in youth.

TL;DR: This systematic review of Garmin activity trackers among adults indicated higher validity of steps; few studies on speed, elevation, and sleep; and lower validity for distance, energy expenditure, and heart rate.

TL;DR: It is suggested that in pregnant women who are obese, a depressed mood, but not pregnancy-related worries, may be associated with less physical activity, which makes women vulnerable for pregnancy complications.

TL;DR: PA is markedly decreased in children with PAH and the use of accelerometer output correlated with clinical disease severity markers and may predict outcome showed an exciting potential of PA as a meaningful endpoint for clinical trials in pediatric PAH, although its clinical utility and prognostic value need to be further validated.

TL;DR: These are the first population-representative findings on the deleterious associations of prolonged sedentary time with cardio-metabolic and inflammatory biomarkers and suggest that clinical communications and preventive health messages on reducing and breaking up sedentaryTime may be beneficial for cardiovascular disease risk.

TL;DR: In this article, the authors examined the associations of objectively measured sedentary time and physical activity with continuous indexes of metabolic risk in Australian adults without known diabetes, and highlighted the importance of decreasing the amount of time spent in physical activity for metabolic health.
