& Butte, 2008), Intelligent Device for Energy Expenditure and Activ-
ity MiniSun (LLC, Fresno, CA) combine five accelerometers which
are worn on chest, thighs and feet (Zhang, 2003) and SenseWear
Armband (Bodymedia, Inc., Pittsburg, PA) combines triaxial accel-
erometry, skin temperature, heat flux and galvanic skin response
in a single device, worn on the upper arm. These devices collect
data on physiological and mechanical variables (Hills, Mokhtar, &
Byrne, 2014). There is no gold standard for objective measurements
of physical activity, the choice is complex and it depends on many
factors such as time, expertise, desired outcomes and desired phys-
ical activity outcomes (Ainsworth, Cahalin, Buman, & Ross, 2015).
Subjective Methods
Subjective assessment of physical activity relies on a child remem-
bering activities they participated in or recalling their perception of
the intensity of the movement. Subjective assessment of physical
activity is useful for measuring the activity of large groups since sub-
jective methods are cheaper than objective. Subjective methods or
self-report of assessing physical activity involves qualitative or de-
scriptive recall of behaviours, logbooks, self-reports, proxy reports
