A comparison of 10 accelerometer non-wear time criteria and logbooks in children
(Journal article; Peer reviewed, 2018)Background There are many unresolved issues regarding data reduction algorithms for accelerometry. The choice of criterion for removal of non-wear time might have a profound influence on physical activity (PA) and sedentary ... -
A systematic review of reliability and objective criterion-related validity of physical activity questionnaires
(Journal article; Peer reviewed, 2012-08-31)Physical inactivity is one of the four leading risk factors for global mortality. Accurate measurement of physical activity (PA) and in particular by physical activity questionnaires (PAQs) remains a challenge. The aim of ... -
Absolute intensity thresholds for tri-axial wrist and waist accelerometer-measured movement behaviors in adults
(Peer reviewed; Journal article, 2023)Aim: This study was aimed to: (1) compare raw triaxial acceleration data from GENEActiv (GA) and ActiGraph GT3X+ (AG) placed on the non-dominant wrist; (2) compare AG placed on the non-dominant and dominant wrist, and ... -
Evaluation of reliability and validity of the General Practice Physical Activity Questionnaire (GPPAQ) in 60–74 year old primary care patients
(Journal article; Peer reviewed, 2015-09-02)BACKGROUND: GPPAQ (General Practice Physical Activity Questionnaire) is a self-assessment physical activity questionnaire widely used in primary care. Reliability and validity data in older people are lacking. The ... -
The force–velocity profile for jumping: What it is and what it is not
(Peer reviewed; Journal article, 2023)Introduction: Force–velocity profiling has been proposed in the literature as a method to identify the overall mechanical characteristics of lower extremities. A force–velocity profile is obtained by plotting for jumps at ... -
I-CONTENT tool for assessing therapeutic quality of exercise programs employed in randomised clinical trials
(Peer reviewed; Journal article, 2020)Objective: When appraising the quality of randomised clinical trial (RCTs) on the merits of exercise therapy, we typically limit our assessment to the quality of the methods. However, heterogeneity across studies can also ... -
