Adults with severe obesity have poorer health, are less active and spend more time sedentary compared to people with a lower body mass index (BMI). There is a pressing need to understand the factors associated with low physical activity (PA) and excessive sedentary time to develop more effective behaviour change interventions for this population. T...
We read with great interest the article by Şekerci and Kitiş [1] describing a Transtheoretical Model (TTM) based intervention delivered by motivational interviews to improve physical exercise in women with diabetes. Although the TTM has been regularly criticized, the Şekerci and Kitiş [1] study illustrates that TTM interventions are effective to im...
This letter highlights three points about a published study of Şekerci and Kitiş: 1- TTM-based interventions to promote PA in clinical practices work, 2- implementation is generally not based on the revised TTM assumptions, 3- the lack of details and information provided about the intervention represent an important obstacle to future reproducibili...

Abstract
Physical activity has been suggested to reduce the high prevalence of metabolic complications in individuals with psychosis. Although high intensity interval training (HIIT) is efficacious in other populations, it remains poorly studied in psychosis.
Methods
Randomized controlled study comparing the effects of 6 months HIIT supervised pr...
Health behaviour change is a cornerstone in the management of obesity, and data on health behaviours, intentions and barriers to change would be useful to inform the development of interventions. The aim of this study was to describe these variables in individuals with obesity, and to compare obesity classes. The study obtained data from the Canadi...
Although higher physical activity (PA) levels are associated with better mental health, previous findings about the shape of the dose–response relationship between PA and mental health are inconsistent. Furthermore, this association may differ according to sedentary levels. We investigated the cross-sectional dose-response associations between obje...
Context: People with severe mental illness (SMI) have a reduced life expectancy notably because of cardiovascular disease and their metabolic consequences, including obesity. Although physical activity (PA) is recommended, people with SMI are insufficiently active and have high levels of sedentary behaviours. So, there is a need to develop interven...
Therefore, the evidence of optimal PA doses for better mental health should be interpreted with caution because sedentary behavior interplays with mental health. In the future, the “move more and sit less” strategy that is recommended for physical health5 might be also be fostered for mental health.
Along the growing interest toward physical activity among people with serious mental illness, researchers faced new challenges such as the initiation, increase, and maintenance of physical activity, as the necessity to develop approaches maximizing physical activity interventions. To favor physical activity interventions, psychological and behavior...
Objective. The present meta-analysis aimed to determine the overall effect of cognitive behavior therapy combined with physical exercise (CBTEx) interventions on depression, anxiety, fatigue, and pain in adults with chronic illness; to identify the potential moderators of efficacy; and to compare the efficacy of CBTEx versus each condition alone (C...
Maintaining a certain level of physical activity is important to prevent some chronic pathologies. This is even more important for people with severe mental health problems, but they have many barriers that make it very difficult for them to be physically active, including lack of motivation. In this paper, we propose an exergame that aims to help...

Background
Among adults with psychotic disorders, negative symptoms as unhealthy lifestyle habits contribute to a high prevalence of metabolic syndrome and obesity. Lifestyle interventions, mainly physical activity (PA) has emerged as an essential component. Furthermore, interval training (IT) was found to be efficacious in other populations but po...
Over the past 30 years, there has been a growing interest in the application of the transtheoretical model (TTM) in the domain of physical activity (PA). Even though this model has been widely used to implement PA interventions, most of these interventions have not used all of the TTM’s theoretical constructs. Indeed, several studies focused exclus...
Physical activity (PA) is a very important component of breast cancer management in complement of the purely carcinologic approach, since it decreases mortality from all causes in these patients. Endurance PA targeted at low to moderate intensity has proved its efficacy and usefulness in this context. Since the efficacy of low intensity PA is expla...
Purpose
