Abstract
BackgroundThe primary aim of this study is to evaluate the effectiveness of different doses (intensity) of supervised exercise training — concomitant with lifestyle counselling — as a primary care intervention tool for the management of metabolic syndrome risk factors in low-active adults with one or more such factors (programme name in Catalan: Bellugat de CAP a peus).Methods/DesignThree-arm, randomized controlled clinical trial implemented in the primary care setting, with a duration of 40 weeks (16 weeks intervention and 24-week follow-up).Adults aged 30 to 55 years with metabolic risk factors will be randomized into three intervention groups: 1) aerobic interval training (16 supervised training lessons) plus a healthy lifestyle counselling programme (6 group and 3 individual meetings); 2) low-to-moderate intensity continuous training (16 supervised training lessons) plus the same counselling programme; or 3) the counselling- programme without any supervised physical exercise.The main output variables assessed will be risk factors for metabolic syndrome (waist circumference, blood pressure, and levels of plasma triglycerides, high-density lipoproteins and glucose), systemic inflammation, cardiorespiratory fitness, physical activity and sedentary behaviour, dietary habits, health-related quality of life, self-efficacy and empowerment. Economic factors will also be analysed in order to determine the cost-effectiveness of the programme. These variables will be assessed three times during the study: at baseline, at the end of the intervention, and at follow-up. We estimate to recruit 35 participants per group.DiscussionThe results of this study will provide insight into the immediate and medium-term effects on metabolic risk and lifestyle of a combined approach involving aerobic interval training and a multidisciplinary behavioural intervention. If effective, the proposed intervention would provide both researchers and practitioners in this field with a platform on which to develop similar intervention programmes for tackling the repercussions of an unhealthy lifestyle.Trial registrationClinical trials.gov.

The primary aim of this study is to evaluate the effectiveness of different doses of supervised exercise training — concomitant with lifestyle counselling — as a primary care intervention tool for the management of metabolic syndrome risk factors in low-active adults with one or more such factors
The primary aim of this study is to evaluate the effectiveness of different doses of supervised exercise training (AIT and traditional continuous training (TCT)), both concomitant with lifestyle counselling, and to compare this with lifestyle counselling (COU) alone as a primary care intervention tool for the management of metabolic syndrome risk factors in low-active adults with one or more such factors
We believe that with our study design we focus on these key aspects
Summary
In its 2008–2013 action plan the WHO [55] states, among others, the following aims: a) the promotion of interventions for the prevention and control of the main modifiable risk factors for non-communicable disease, b) the implementation of actions to help individuals to enhance their self-efficacy, improving literacy and providing tools for self-control, and c) the promotion of research to establish the cost/efficacy relationship of these interventions. In order to achieve long-lasting and successful outcomes these programmes need to include psychological goals and strategies (mood, literacy, self-efficacy, social integration) focused on behaviour change In this regard, our study includes a lifestyle counselling intervention that incorporates strategies for promoting regular physical activity, minimizing sedentary behaviour, improving dietary habits and enhancing participants’ self-efficacy. Our study includes a lifestyle counselling intervention that incorporates strategies for promoting regular physical activity, minimizing sedentary behaviour, improving dietary habits and enhancing participants’ self-efficacy To our knowledge, this would be the first study in Spain to analyse the effect of AIT in conjunction with strategies to promote behaviour change and empower participants.
