The objective was to analyse changes in physical activity and health-related quality of life among participants in five similar 'Exercise on Prescription' (EoP) programmes. Methods: The analysis was based on self-reported information in a follow-up design without a control group. The intervention comprised group training twice weekly in the first 2 months and once weekly in the following 2 months (24 sessions in all) combined with four to five sessions of motivational counselling. Self-report questionnaires were administered at the first contact and again after 4, 10 and 16 months. Outcome measures were changes in self-reported activity levels converted to metabolic equivalents and health-related quality of life measured by standard instruments (SF-12v2 and EQ-5D). Results: 449 individuals (59% women, mean age 57 years) agreed to participate in the study. Dropout was considerable [123 (27%); 231 (52%) 297 (66%) after 4, 10 and16 months]. Participants increased their physical activity level and health-related quality of life from baseline to 4 months and maintained improvement throughout the observation period. One in three to six participants increased their physical activity level and one in 4-10 achieved improvements in health-related quality of life. Conclusion: Exercise on prescription can contribute to improvements in physical activity level and health-related quality of life in physically inactive patients with or at increased risk of developing lifestyle diseases. An acceptable number of participants achieved and maintained improvements in physical activity level and health-related quality of life.

Data was collected using individual semi-structured interviews with 6 male employees with a mean age of 46 years (range 32-64). Respondents were recruited using purposive sampling, aimed at non-adhering employees. The interview guide was constructed based on the TPB and TTM. The interviews lasted between 30 and 50 minutes. Thematic analysis was done by analyst triangulation. Results: The majority of respondents had a low sense of control over factors influencing their intent such as time of day, distance to activity, work planning and low level of perceived behavioural control and half the respondents reported that they felt able to overcome these factors but lacked an incentive. Disadvantages, such as perceived low level of physical ability, clearly outweighed advantages: processes of change were dominated by cognitive processes and only one ABOUT THE AUTHORS

In total, 573 office workers were cluster-randomized to: 1WS: one 60-min supervised session/week, 3WS: three 20-min supervised sessions/week, 9WS: nine 7-min supervised sessions/week, 3MS: three 20-min sessions/week with minimal supervision, or REF: a reference group without training. Outcomes were diary-based compliance, total training volume, muscle performance and questionnaire-based health, behavior and work performance. Comparisons were made among the WS training groups and between 3WS and 3MS. If no difference, training groups were collapsed (TG) and compared with REF. Results demonstrated similar degrees of compliance, mean(range) of 39(33-44)%, and total training volume, 13.266(11.977-15.096)kg. Musculoskeletal pain in neck and shoulders were reduced with approx. 50% in TG, which was significant compared with REF. Only the training groups improved significantly their muscle strength 8(4-13)% and endurance 27(12-37)%, both being significant compared with REF. No change in workability, productivity or self-rated health was demonstrated. Secondary analysis showed exercise self-efficacy to be a significant predictor of compliance. Regardless of training schedule and supervision, similar degrees of compliance were shown together with reduced musculoskeletal pain and improved muscle performance. These findings provide evidence that a great degree of flexibility is legitimate for companies in planning future implementation of physical exercise programs at the workplace.

Increased physical activity during school hours is associated with better physical, psychological and social health and well-being. Unfortunately many children and young people exercise insufficiently to benefit from positive factors like well-being. The main aim of this study is to develop, implement and evaluate a multi-component, school-based, physical activity intervention to improve psychosocial well-being among school-aged children and youths from the 4 th to the 6 th grade (10-13 years). Methods: A four-phased interventiondesign, pilot, RCT, evaluation-is carried out for the development, implementation and evaluation of the intervention which are guided by The Medical Research Council framework for the development of complex interventions. 24 schools have been randomized and the total study population consists of 3124 children (baseline), who are followed over a period of 9 months. Outcome measure data at the pupil level are collected using an online questionnaire at baseline and at follow-up, 9 months later with instruments for measuring primary (general physical self-worth) and secondary outcomes (self-perceived sport competences, body attractiveness, scholastic competences, social competences and global self-worth; enjoyment of PA; self-efficacy; and general well-being) that are both valid and manageable in setting-based research. The RE-AIM framework is applied as an overall instrument to guide the evaluation. Discussion: The intervention focuses on the mental benefits of physical activity at school, which has been a rather neglected theme in health promotion research during recent decades. This is unfortunate as mental health has been proclaimed as one of the most important health concerns of the 21 st century. Applying a cluster RCT study design, evaluating the real-world effectiveness of the intervention, this study is one of the largest physical activity intervention projects promoting psychosocial well-being among children and youths. Through a comprehensive effectiveness evaluation and a similar substantial process evaluation, this study is designed to gain knowledge on a broad variety of implementation issues and give detailed information on project delivery and challenges at the school levelamong other things to better inform future practice.

A 20-week cluster randomized controlled trial among 351 office workers was randomized into three groups: two training groups with the same total amount of planned exercises three times per week (1) with supervision (3WS) throughout the intervention period, (2) with minimal supervision (3MS) only initially, and (3) a reference group (REF). Main outcome is self-reported pain intensity in neck and shoulder (scale 0-9) and headache (scale 0-10). Intention-to-treat analyses showed a significant decrease in neck pain intensity the last 7 days in 3MS compared with REF: -0.5 ± 0.2 (P < 0.02) and a tendency for 3WS versus REF: -0.4 ± 0.2 (P < 0.07). Intensity of headache the last month decreased in both training groups: 3WS versus REF: -1.1 ± 0.2 (P < 0.001) and 3MS versus REF: -1.1 ± 0.2 (P < 0.001). Additionally, da...

Some studies show a positive effect of exercise prescription on specific lifestyle diseases. Others only show moderately positive or no effect on physical activity level. Furthermore, the challenge is adherence of participants to a physically active lifestyle on a long term basis after intervention. Therefore, it is essential for offering successful prescribed interventions aiming towards behaviour change to focus on psychological and social issues as well as physiological issues. The aim of this study is to assess the short and long term development of psychological conditions in two different Exercise on Prescription groups; The Treatment Perspective and The Preventive Perspective behaviour. Thus, the aim of this paper is to describe the design used.
