The background and purpose of this paper is to investigate adherence, exercise performance levels and associated factors in head and neck cancer (HNC) patients participating in a guided home-based prophylactic exercise program during and after treatment [swallowing sparing intensity modulated radiation therapy (SW-IMRT)]. Fifty patients were included in the study. Adherence was defined as the percentage of patients who kept up exercising; exercise performance level was categorized as low: ≤1, moderate: 1–2, and high: ≥2 time(s) per day, on average. Associations between 6- and 12-week exercise performance levels and age, gender, tumour site and stage, treatment, intervention format (online or booklet), number of coaching sessions, and baseline HNC symptoms (EORTC-QLQ-H&N35) were investigated. Adherence rate at 6 weeks was 70% and decreased to 38% at 12 weeks. In addition, exercise performance levels decreased over time (during 6 weeks: 34% moderate and 26% high; during 12 weeks: 28% moderate and 18% high). The addition of chemotherapy to SW-IMRT [(C)SW-IMRT] significantly deteriorated exercise performance level. Adherence to a guided home-based prophylactic exercise program was high during (C)SW-IMRT, but dropped afterwards. Exercise performance level was negatively affected by chemotherapy in combination with SW-IMRT.
Purpose: To identify subgroups of patients with oesophageal cancer based on exercise intensity during prehabilitation, and to investigate whether training outcomes varied between subgroups. Materials and methods: Data from a multicentre cohort study were used, involving participants following prehabilitation before oesophagectomy. Hierarchical cluster analysis was performed using four cluster variables (intensity of aerobic exercise, the Borg score during resistance exercise, intensity of physical activity, and degree of fatigue). Aerobic capacity and muscle strength were estimated before and after prehabilitation. Results: In 64 participants, three clusters were identified based on exercise intensity. Cluster 1 (n = 23) was characterised by fatigue and physical inactivity, cluster 2 (n = 9) by a low training capacity, despite high physical activity levels, and cluster 3 (n = 32) by a high training capacity. Cluster 1 showed the greatest improvement in aerobic capacity (p = 0.37) and hand grip strength (p = 0.03) during prehabilitation compared with other clusters. Conclusions: This cluster analysis identified three subgroups with distinct patterns in exercise intensity during prehabilitation. Participants who were physically fit were able to train at high intensity. Fatigued participants trained at lower intensity but showed the greatest improvement. A small group of participants, despite being physically active, had a low training capacity and could be considered frail.

Aging is associated with a decline in the ability to carry out daily tasks. Physical activity can delay or diminish the decline and increase the ability of older adults to live independently at home. Performing home-based exercises can help older adults achieve the recommended levels of physical activity. Technology allows exercise programs to be tailored to individual needs. This thesis describes a blended intervention that was developed and evaluated according to the Medical Research Council framework. The principal findings are that older adults are motivated to perform technology-supported home-based exercises if they help them maintain self-reliance and there is sufficient guidance, safety is taken into account, and adherence is stimulated. To meet those conditions, a blended intervention was developed that was based on functional exercises, behavior change theory and human guidance. A custom-made tablet application appears to be usable by the target audience. A process evaluation has shown that the tablet as well as the coach support older adults in the various phases of self-regulating their exercise behavior. The blended intervention stimulates intrinsic motivation by supporting the autonomy of participants, fostering competence and, for some, meeting the need for relatedness by offering emotional support. Data derived from the tablet demonstrate that older adults participating in the intervention exhibit exercise behavior that is in line with WHO guidelines and that engagement with the tablet was a contributing factor. Future work should include assessment of intervention fidelity and explore which aspects of coaching can and cannot be further automated.
