Background: This study aims to investigate the relationship between post-diagnosis physical activity and mortality in patients with selected noncommunicable diseases, including breast cancer, lung cancer, type 2 diabetes, ischemic heart disease, stroke, chronic obstructive pulmonary disease (COPD), osteoarthritis, low back pain and major depressive disorder. Methods: A systematic search was conducted of PubMed, Scopus and the Web of Science from their inception to August 2018. Additionally, the search was updated in August 2019. Eligibility criteria included prospective observational studies examining the relationship between at least three physical activity categories (e.g. low, moderate, high) and all-cause mortality as the primary outcome. Results: In total, 28 studies were included in the meta-analysis: 12 for breast cancer, 6 for type 2 diabetes, 8 for ischemic heart disease and 2 for COPD. The linear meta-analysis revealed that each 10 metabolic equivalent task hours increase of physical activity per week was associated with a 22% lower mortality rate in breast cancer patients (Summary Hazard Ratio [HR], 0.78; 95% CI: 0.71, 0.86; I²: 90.1%), 12% in ischemic heart disease patients (HR, 0.88; 95% CI: 0.83, 0.93; I²: 86.5%), 30% in COPD patients (HR, 0.70; 95% CI: 0.45, 1.09; I²: 94%) and 4% in type 2 diabetes patients (HR, 0.96; 95% CI: 0.93, 0.99; I²: 71.8%). There was indication of a non-linear association with mortality risk reductions even for low levels of activity, as well as a flattening of the curve at higher levels of activity. The certainty of evidence was low for breast cancer, type 2 diabetes and ischemic heart disease but only very low for COPD. Conclusion: Higher levels of post-diagnosis physical activity are associated with lower mortality rates in breast cancer, type 2 diabetes, ischemic heart disease and COPD patients, with indication of a no-threshold and non-linear dose–response pattern.

The purpose of this perspective is (1) to incorporate recent psychological health behaviour change (HBC) theories into exercise therapeutic programmes, and (2) to introduce the International Classification of Functioning (ICF)-based concept of a behavioural exercise therapy (BET). Relevant personal modifiable factors of physical activity (PA) were identified based on three recent psychological HBC theories. Following the principles of intervention mapping, a matrix of proximal programme objectives specifies desirable parameter values for each personal factor. As a result of analysing reviews on behavioural techniques and intervention programmes of the German rehabilitation setting, we identified exercise-related techniques that impact the personal determinants. Finally, the techniques were integrated into an ICF-based BET concept. Individuals' attitudes, skills, emotions, beliefs and knowledge are important personal factors of PA behaviour. BET systematically addresses these personal factors by a systematic combination of adequate exercise contents with related behavioural techniques. The presented 28 intervention techniques serve as a theory-driven "tool box" for designing complex BET programmes to promote PA. The current paper highlights the usefulness of theory-based integrative research in the field of exercise therapy, offers explicit methods and contents for physical therapists to promote PA behaviour, and introduces the ICF-based conceptual idea of a BET. Implications for Rehabilitation Irrespective of the clients' indication, therapeutic exercise programmes should incorporate effective, theory-based approaches to promote physical activity. Central determinants of physical activity behaviour are a number of personal factors: individuals' attitudes, skills, emotions, beliefs and knowledge. Clinicians implementing exercise therapy should set it within a wider theoretical framework including the personal factors that influence physical activity. To increase exercise-adherence and promote long-term physical activity behaviour change, the concept of a behavioural exercise therapy (BET) offers a theory-based approach to systematically address relevant personal factors with a combination of adequate contents of exercise with exercise-related techniques of behaviour change.

Physical exercise is effective in improving functional outcomes in persons with multiple sclerosis (pwMS). We evaluated the feasibility and effectiveness of internet-based exercise training (e-training) for pwMS on health-related quality of life (HrQoL). Secondary outcomes were muscle strength, aerobic capacity, lung function, physical activity, and fatigue. This is a randomised, controlled trial with a wait-list control group. Data were collected at baseline, after three and six months, and analysed using a hybrid linear model. One-hundred twenty-six pwMS participated in the home-based aerobic (1×/week) and strength training (2×/week) intervention that was supervised and documented via an internet-platform. The intervention group received e-training for six months, and the control group received e-training after a three months waiting period. Significant differences between the groups were only observed for muscle strength (knee flexion (effect size ES = 0.3, p = 0.003), knee extension (ES = 0.24, p = 0.015)), peak expiratory flow (ES = 0.2, p = 0.039), and sports activity (ES = 0.33, p = 0.001) after three months. E-training had no effect on HrQoL but did on muscle strength, lung function, and physical activity. It is a promising and feasible approach to facilitate large-scale, yet individual, training support.

Hintergrund: Zentrales Ziel der Bewegungstherapie in der Rehabilitation ist die Hinführung zu einem körperlich aktiven Lebensstil. Bisher dominieren in der Bewegungstherapie funktionsorientierte Ansätze, die nur bedingt eine langfristige Änderung des Bewegungsverhaltens unterstützen. Demgegenüber werden verhaltensbezogene Aspekte selten in bewegungstherapeutische Interventionen integriert. Ziel: Aufbauend auf einer systematischen Reflektion psychologischer Theorien des Gesundheitsverhaltens sollen effektive Methoden und Inhalte speziell für eine verhaltensbezogene Bewegungstherapie (VBT) abgeleitet werden, die sich auf die Bindung an körperlich-sportliche Aktivität richten. Konzeptionell-methodisches Vorgehen: Ausgangspunkt bildet eine theoriegeleitete Bestimmung indviduumsbezogener Verhaltensdeterminanten körperlich-sportlicher Aktivitäten. Anschließend erfolgt die Identifikation von Interventionstechniken zu deren Beeinflussung. Die Wirksamkeit der Techniken wird anhand ihres Effektes auf die Steigerung der körperlichen Aktivitäten bewertet. Hierfür wird die vorhandene Evidenz auf Basis internationaler Übersichtsarbeiten sowie Kontrollgruppenstudien aus dem deutschen Rehabilitationssetting zusammengefasst. Abschließend werden Empfehlungen zur Gestaltung einer VBT abgeleitet. Ergebnisse: Insgesamt konnten für die VBT 28 Techniken zur Förderung körperlich-sportlicher Aktivität identifiziert werden. Effektiv ist insbesondere die Anwendung von Selbstbeobachtung (z. B. Bewegungstagebücher) in verschiedenen Kombinationen mit weiteren Techniken, wie z. B. Vertragsvereinbarungen, Feedback, Belohnung, Generierung vielfältiger Bewegungserfahrungen, Handlungs- und Bewältigungsplanung. Diskussion: Die Integration von verhaltensbezogenen Interventionstechniken in die Bewegungstherapie stellt einen vielversprechenden Weg zur Initiierung eines körperlich aktiven Lebensstils dar. Background: The promotion of a physically active lifestyle has become an important issue in exercise therapy. Exercise-only interventions are frequently used for the rehabilitation of individuals with chronic diseases. These do indeed improve functional and physical performance, but they are not alone sufficient to initiate long lasting changes in physical-activity behaviour. Behaviour-related aspects are rarely integrated into exercise-therapy interventions. Objective: Based on theories of health behaviour change, effective techniques for changing physical-activity behaviour in the context of exercise therapy will be identified. Methodology: The starting point is a theory-driven definition of individual behavioural determinants of physical activity and the identification of techniques for influencing the determinants. Subsequently, the potential of the techniques for enhancing physical activity is evaluated. The available evidence was reviewed on the basis of international reviews and control-group studies from the German rehabilitation setting. Finally, recommendations are offered for designing exercise-based interventions to promote participation in and adherence to physical activity. Results: A total of 28 techniques for the promotion of physical activity behaviour were identified. An approach that proved particularly effective was self-monitoring of physical activity behaviour in a variety of combinations with other techniques, such as contracting, feedback, rewards, generating one's own varied exercise experience, action planning and barrier management. Discussion: The integration of behaviour-related techniques in the context of exercise therapy interventions shows great promise as a means of initiating and promoting a physically active lifestyle.

Background: Existing physical activity guidelines predominantly focus on healthy age-stratified target groups. The objective of this study was to develop evidence-based recommendations for physical activity (PA) and PA promotion for German adults (18–65 years) with noncommunicable diseases (NCDs). Methods: The PA recommendations were developed based on existing PA recommendations. In phase 1, systematic literature searches were conducted for current PA recommendations for seven chronic conditions (osteoarthrosis of the hip and knee, chronic obstructive pulmonary disease, stable ischemic heart disease, stroke, clinical depression, and chronic non-specific back pain). In phase 2, the PA recommendations were evaluated on the basis of 28 quality criteria, and high-quality recommendations were analysed. In phase 3, PA recommendations for seven chronic conditions were deducted and then synthesised to generate generic German PA recommendations for adults with NCDs. In relation to the recommendations for PA promotion, a systematic literature review was conducted on papers that reviewed the efficacy/effectiveness of interventions for PA promotion in adults with NCDs. Results: The German recommendations for physical activity state that adults with NCDs should, over the course of a week, do at least 150 min of moderate-intensity aerobic PA, or 75 min of vigorous-intensity aerobic PA, or a combination of both. Furthermore, muscle-strengthening activities should be performed at least twice a week. The promotion of PA among adults with NCDs should be theory-based, specifically target PA behaviour, and be tailored to the respective target group. In this context, and as an intervention method, exercise referral schemes are one of the more promising methods of promoting PA in adults with NCDs. Conclusion: The development of evidence-based recommendations for PA and PA promotion is an important step in terms of the initiation and implementation of actions for PA-related health promotion in Germany. The German recommendations for PA and PA promotion inform adults affected by NCDs and health professionals on how much PA would be optimal for adults with NCDs. Additionally, the recommendations provide professionals entrusted in PA promotion the best strategies and interventions to raise low PA levels in adults with NCDs. The formulation of specific PA recommendations for adults with NCDs and their combination with recommendations on PA promotion is a unique characteristic of the German recommendations.

This study applies a cluster analysis to identify typical physical activity (PA) and sedentary behaviour (SB) patterns in people with chronic obstructive pulmonary disease (COPD) before starting pulmonary rehabilitation (PR). We implemented an observational design which assessed baseline data of objectively measured PA and SB from the STAR (Stay Active after Rehabilitation) study. A total of 355 persons wore an accelerometer (Actigraph wGT3X) for seven days before the start of their PR. Sociodemographic and disease-related parameters were assessed at the start of PR. We applied cluster analysis and compared clusters applying univariate variance analyses. Data was available for 326 persons (31.6% women; age ø = 58 years). Cluster analysis revealed four movement clusters with distinct PA and SB patterns: Sedentary non-movers (28.5%), sedentary occasional movers (41.7%), sedentary movers (19.6%), and sedentary exercisers (10.1%). The four clusters displayed varying levels of moderate PA before rehabilitation (Ø daily min: 9; 28; 38; 70). Notably, all four clusters displayed considerably long average sedentary time per day (Ø daily minutes: 644; 561; 490; 446). The clusters differed significantly in disease-related parameters of GOLD severity, FEV1, CAT, and 6-Min-Walk-Test. In addition to PA promotion, PR programs should consider the reduction of sedentary behaviour as a valuable goal.
