Virtual or In-Person: A Mixed Methods Survey to Determine Exercise Programming Preferences during COVID-19.

A survey was conducted to identify barriers and facilitators to engaging in virtual and in-person cancer-specific exercise during COVID-19. A theory-informed, multi-method, cross-sectional survey was electronically distributed to 192 individuals with cancer investigating preferences towards exercise programming during COVID-19. Respondents had previously participated in an exercise program and comprised two groups: those who had experience with virtual exercise programming ('Virtual') and those who had only taken part in in-person exercise ('In-Person'). Quantitative data were summarized descriptively. Qualitative data were thematically categorized using framework analysis and findings were mapped to an implementation model. The survey completion response rate was 66% (N = 127). All respondents identified barriers to attending in-person exercise programming during COVID-19 with concerns over the increased risk of viral exposure. Virtual respondents (n = 39) reported: (1) feeling confident in engaging in virtual exercise; and (2) enhanced motivation, accessibility and effectiveness as facilitators to virtual exercise. In-Person respondents (n = 88) identified: (1) technology as a barrier to virtual exercise; and (2) low motivation, accessibility and exercise effectiveness as barriers towards virtual exercise. Sixty-six percent (n = 58) of In-Person respondents reported that technology support would increase their willingness to exercise virtually. With appropriately targeted support, perceived barriers to accessing virtual exercise-including motivation, accessibility and effectiveness-may become facilitators. The availability of technology support may increase the engagement of individuals with cancer towards virtual exercise programming.

Exercise, sleep and cancer-related fatigue: Are they related?

Cancer-related fatigue (CRF) is a commonly reported and debilitating side effect of cancer and/or cancer treatment. Sleep disorders are also highly reported in the cancer population; however it is unknown if sleep is associated with fatigue. In the general population, exercise has been shown to improve sleep, however in the cancer population this idea is under investigation. The primary purposes of this review were to: (i) review the prevalence and causes of sleep disorders in cancer patients and survivors, (ii) examine the relationship between sleep and CRF and (iii) review the impact of exercise interventions on sleep in cancer patients and survivors. A scoping review of the literature was conducted regarding exercise interventions in cancer patients and survivors with sleep as at least one outcome measure. A search of the literature revealed limited studies (n=21) assessing the effect of exercise on sleep disorders in the cancer population. Methodological issues are evident because assessing sleep is often not the main outcome of interest. The reviewed studies revealed that exercise positively impacts sleep quality and quantity. There seems to be possible relationship between sleep disorders, exercise and CRF. Further investigation of this relationship is necessary, specifically using objective measurement tools, in large, controlled studies, focusing on sleep as the primary outcome.

Neuromuscular fatigue during exercise: Methodological considerations, etiology and potential role in chronic fatigue.

The term fatigue is used to describe a distressing and persistent symptom of physical and/or mental tiredness in certain clinical populations, with distinct but ultimately complex, multifactorial and heterogenous pathophysiology. Chronic fatigue impacts on quality of life, reduces the capacity to perform activities of daily living, and is typically measured using subjective self-report tools. Fatigue also refers to an acute reduction in the ability to produce maximal force or power due to exercise. The classical measurement of exercise-induced fatigue involves neuromuscular assessments before and after a fatiguing task. The limitations and alternatives to this approach are reviewed in this paper in relation to the lower limb and whole-body exercise, given the functional relevance to locomotion, rehabilitation and activities of daily living. It is suggested that under some circumstances, alterations in the central and/or peripheral mechanisms of fatigue during exercise may be related to the sensations of chronic fatigue. As such, the neurophysiological correlates of exercise-induced fatigue are briefly examined in two clinical examples where chronic fatigue is common: cancer survivors and people with multiple sclerosis. This review highlights the relationship between objective measures of fatigability with whole-body exercise and perceptions of fatigue as a priority for future research, given the importance of exercise in relieving symptoms of chronic fatigue and/or overall disease management. As chronic fatigue is likely to be specific to the individual and unlikely to be due to a simple biological or psychosocial explanation, tailored exercise programmes are a potential target for therapeutic intervention.

A community-based physical activity program for adolescents with cancer (project TREK): program feasibility and preliminary findings.

INTRODUCTION: As the number of pediatric survivors continues to grow, a greater emphasis is being placed on identifying long-term health risk/protecting behaviors. The primary purpose of this pilot study was to examine the feasibility of a theoretically-based physical activity (PA) intervention in adolescents with cancer. METHODS: A group PA intervention was administered to participants over 16 weeks. Program attendance/adherence, total PA, physical fitness, and quality of life (QOL) were assessed at 5 different intervals over the 1-year study duration. RESULTS: Over a period of 6 weeks, 11 adolescents responded to recruitment efforts. Ten ultimately enrolled and completed the 1-year study. Overall, the program was well received with attendance over the 16-week intervention averaging 81.5%. Although improvements in total PA, physical fitness, and QOL were noted across the intervention, follow-up data revealed that participants failed to maintain their postintervention PA levels at both the 3 and 12-month follow-up assessments. CONCLUSIONS: Adolescents with a history of cancer are undoubtedly susceptible to the same maladaptive health habits as are their healthy peers. Innovative interventions aimed at improving their adherence to positive behavioral interventions, such as PA are warranted. Although not without limitations, this study provides preliminary data in support of a university-sponsored PA intervention.
