The aim of this paper is to present a smartphone
based system to assess daily energy expended in physical activ-
ity (PA). Nowadays, sedentary li
festyle is increasingly recog-
nized as a serious, worldwide public health concern, because
sedentary behaviors ar
e associated to cardiovascular diseases
and premature death. A smartphone application has been
developed for data gathering from internal motion sensor,
wireless wearable heart rate moni
tor and user filled out forms.
The data collected have been sent to a remote server to esti-
mate the total energy expenditure (TEE), which has been
determined by the sum of three components: basal energy
expenditure (BEE), physical activi
ty (AEE) and thermic effect
of food (TEF). In this study, the subjects have used the devel-
oped application for seven consecutive days, which represents
a typical week. Then, a profil
e of their daily TEE has been
obtained. The presented system is a useful tool to generate
personalized recommendations to maintain energy balance
through more active lifestyle
and healthier eating habits. |
