Methods for objective measure, quantification and analysis of sedentary behaviour and inactivity

Sitting patterns at work: objective measurement of adherence to current recommendations

“…Sedentary behaviour can be defined as time spent sitting (Biddle 2007;Katzmarzyk et al 2009;Owen et al 2009) or sitting/supine (Chastin and Granat 2010;Jans et al 2007). Recently, it has been shown that sedentary behaviour is a risk factor for many health conditions often independent of MVPA (Healy et al 2008a;Katzmarzyk et al 2009).…”

Association of Sedentary Behaviour and Cardiometabolic Risk Biomarkers among Chinese Females: A Cross-sectional Study

“…It is calculated by dividing the body weight in kilogram by height in m 2 . BMI of majority of the participants fall under healthy weight category which is 68.1% and only 3 participants had high BMI under obese category.…”

“…Sedentary behavior (SB) is characterized by waking time spent sitting, reclining, and lying down, and by low energy expenditure [2]. This behavior has two distinct effects: time spent in SB reduces engagement in physical activity (which reduces benefits from the wellresearched health and well-being enhancing effects of physical activity) and specific deleterious effects of SB such as mortality associated with TV viewing [3].…”

Muscle activity patterns and spinal shrinkage in office workers using a sit–stand workstation versus a sit workstation

“…This study is one of very few that have measured muscle activity using EMG shorts, which have been reported to provide an accurate and detailed assessment of muscle activity across the entire continuum of daily life (Tikkanen et al 2013). Compared with analysis of activity outcomes from accelerometers and postural data (Chastin and Granat 2010), EMG as a direct measure of muscle activity provides further physiological insight into changes in muscle activity and inactivity time, and the associated cardio-metabolic impact when reducing sitting time (Tikkanen et al 2014;Pesola et al 2014Pesola et al , 2015.…”
