Measuring Physical Activity with Sensors : A Qualitative Study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2009)
Description of spatio-temporal gait parameters in elderly people and their association with history of falls: Results of the population-based cross-sectional KORA-Age study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-03-25)
Background: In this epidemiological study we described the characteristics of spatio-temporal gait parameters among a representative, population-based sample of 890 community-dwelling people aged 65 to 90 years. In addition, we investigated the associations between certain gait parameters and a history of falls in study participants. <p>Methods: In descriptive analyses spatio-temporal gait parameters ...
Exploring patterns of accelerometry-assessed physical activity in elderly people
(Journal article; Tidsskriftartikkel; Peer reviewed, 2014)
Design and evaluation of a computer-based 24-Hour physical activity recall (cpar24) instrument
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-05-30)
<p><i>Background</i>: Widespread access to the Internet and an increasing number of Internet users offers the opportunity of using Web-based recalls to collect detailed physical activity data in epidemiologic studies.</p> <p><i>Objective</i>: The aim of this investigation was to evaluate the validity and reliability of a computer-based 24-hour physical activity recall (cpar24) instrument with ...
Gender differences in the association between grip strength and mortality in older adults: results from the KORA-age study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-11-30)
Background: Reduced muscular strength in the old age is strongly related to activity impairment and mortality. However, studies evaluating the gender-specific association between muscularity and mortality among older adults are lacking. Thus, the objective of the present study was to examine gender differences in the association between muscular strength and mortality in a prospective population-based ...
Uni- and triaxial accelerometric signals agree during daily routine, but show differences between sports
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-10-10)
Accelerometers objectively monitor physical activity, and ongoing research suggests they can also detect patterns of body movement. However, different types of signal (uniaxial, captured by older studies, vs. the newer triaxial) and or/device (validated Actigraph used by older studies, vs. others) may lead to incomparability of results from different time periods. Standardization is desirable. We ...
Validity of the Polar M430 Activity Monitor in Free-Living Conditions: Validation Study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-08-16)
<i>Background</i>: Accelerometers, often in conjunction with heart rate sensors, are extensively used to track physical activity (PA) in research. Research-grade instruments are often expensive and have limited battery capacity, limited storage, and high participant burden. Consumer-based activity trackers are equipped with similar technology and designed for long-term wear, and can therefore ...
