Despite the accumulation of scientific evidence supporting the benefits of physical activity, the general population remains insufficiently active and this situation is even worsened for some specific populations such as obese people (Barker et al., 2019). It is therefore becoming urgent to develop interventions that can effectively change individu...

Introduction Physical inactivity and excessive sedentary behaviours are major preventable causes in both the development and the treatment of obesity and type 2 diabetes mellitus (T2DM). Nevertheless, current programmes struggle to engage and sustain physical activity (PA) of patients over long periods of time. To overcome these limitations, the Di...
Article
With highly variable types of coronavirus disease 2019 (COVID-19) symptoms in both severity and duration, there is today an important need for early, individualized, and multidisciplinary strategies of rehabilitation. Some patients present persistent affections of the respiratory function, digestive system, cardiovascular function, locomotor system...

Methods to measure physical activity and sedentary behaviors typically quantify the amount of time devoted to these activities. Among patients with chronic diseases, these methods can provide interesting behavioral information, but generally do not capture detailed body motion and fine movement behaviors. Fine detection of motion may provide additi...
Article
Physical Activity is a cornerstone in the management of obesity and prevention of Non-Communicable Diseases. Supervised PA training effectively increases PA levels, but long-term PA is difficult to maintain because of psychological and physical barriers. The aim of this study was, first, to characterise the spontaneous initial behavioural, intentio...
