Barriers To Exercise

In the United Kingdom, there are physical activity guidelines specifically for older adults. Self-report data indicate that approximately 15% of those achieved 65+ the activity target of 30 minutes of moderate intensity exercise on 5 (or more) days a week and 30% when the 150 minutes may be achieved in 10-minute (or greater) bursts. Levels of activity are higher among men, the more affluent, and those aged 65–74 but we have little evidence about levels of activity among the ageing ethnic minority population. Reanalysis of 109 interviews conducted with people aged 50+ from Bangladeshi and Pakistani communities was undertaken to explore how participants talk about physical activity in terms of their daily lives. Few, 13 participants (7 females), reported that physical activity and/or exercise formed part of their daily routine; a further 7 had been advised to take exercise by their doctors but had not done so and 9 described why they could not exercise. Barriers to exercise included lack of time (because of work or childcare) and cultural factors such as ideas about age and gender appropriate behaviour. We need to develop appropriate interventions to encourage exercise which address these cultural factors and general barriers to exercise.

The purpose of this narrative review is to provide an overview of the currently available knowledge about the mechanisms by which physical activity may affect metastatic development. The search terms exercise [Title/Abstract] AND metastasis [Title/Abstract] returned 222 articles on PUBMED on the 10 February 2019. After careful analysis of the abstracts, a final selection of 24 articles was made. Physical activity regulates the levels of metastatic factors in each of the five steps of the process. Moderate intensity exercise appears to prevent tumor spread around the body, among others, by normalizing angiogenesis, destroying circulating tumor cells, and decreasing endothelial cells permeability. Contrarily, high-intensity exercise seems to favor cancer dissemination, likely through excessive stress, which can be somewhat counteracted by an appropriate warm-up. In conclusion, chronic adaptations to moderate-intensity endurance exercise seem the most effective way to achieve a preventive effect of exercise on metastases. Altogether, the data gathered here reinforce the importance of encouraging cancer patients to perform moderate physical activity several times a week. To limit the undesired events thereof, a good knowledge of the patient’s training level is important to establish an adapted exercise training program.

Paired Associative Stimulation

Abstract Paired associative stimulation (PAS) can induce plasticity in the motor cortex, as measured by changes in corticospinal excitability (CSE). This effect is attenuated in older and less active individuals. Although a single bout of exercise enhances PAS-induced plasticity in young, physically inactive adults, it is not yet known if physical activity interventions affect PAS-induced neuroplasticity in middle-aged inactive individuals. Sixteen inactive middle-aged office workers participated in a randomized cross-over design investigating how CSE and short-interval intracortical inhibition (SICI) were affected by PAS preceded by 3 h of sitting (SIT), 3 h of sitting interrupted every 30 min by 3 min of frequent short bouts of physical activity (FPA) and 2.5 h of sitting followed by 25 min of moderate-intensity exercise (EXE). Transcranial magnetic stimulation was applied over the primary motor cortex (M1) of the dominant abductor pollicis brevis to induce recruitment curves before and 5 min and 30 min post-PAS. Linear mixed models were used to compare changes in CSE using time and condition as fixed effects and subjects as random effects. There was a main effect of time on CSE and planned within-condition comparisons showed that CSE was significantly increased from baseline to 5 min and 30 min post-PAS, in the FPA condition, with no significant changes in the SIT or EXE conditions. SICI decreased from baseline to 5 min post-PAS, but this was not related to changes in CSE. Our findings suggest that in middle-aged inactive adults, FPAs may promote corticospinal neuroplasticity. Possible mechanisms are discussed.

Preliminary assessment was made concerning perceptions of the newly developed bean-rate guide, devised as an educational tool to promote physical activity. Unlike the traditional target heart-rate chart, the heart-rate guide illustrates the value of low to moderate intensity physical activity. Following a brief lecture about the Surgeon General's report on physical activity and health and the usefulness of heart-rate charts and guides, 120 college students ( M age 21.5 ± 2.8 yr.) completed a self-report survey consisting of statements regarding their use of target heart rates during exercise and their perceptions of the new heart-rate guide as compared to the traditional heart-rate chart. 83% of the subjects reported that the new guide better illustrated the findings from the Surgeon General's report, 5% reported no difference between the guide and the chart, and 12% reported that the chart better illustrated the report's findings ( p<.01). 48% never measure their heart rates when they exercise, 48% sometimes measure their heart rates and 4% always do so ( p< 01). While the new guide should not replace the traditional chart, these results suggest that college students perceive the heart-rate guide as a useful tool despite the fact that only a small percentage of students regularly measure their heart rates when they exercise.

AbstractBackground:As epidemiological studies have become more complex, demands for short, easily administered measures of risk factors have increased. This study investigates whether such a measure of physical activity is associated with the risk of death from all causes and death from specific causes.Methods:A prospective follow-up study of 11 090 men and women, aged 35–64 years, recruited from five UK general practices who responded to a postal questionnaire in 1989. Self-reported frequency of vigorous-intensity physical activity and data on confounding factors were collected at baseline survey. Death notifications up to 31 December 2001 were provided by the Office for National Statistics. The relative risk (and 95% confidence interval) of dying associated with each level of exposure to physical activity was estimated by the hazard ratio in a series of Cox regression models.Results:After > 10 years' follow-up there were 825 deaths among the 10 522 subjects with no previous history of angina or myocardial infarction. Participation in vigorous exercise was associated with a significantly lower risk of all-cause mortality. Similar associations were found for ischaemic heart disease and cancer mortality, although the relationships were not significant at the 5% level.Conclusions:Simple measures of self-reported vigorous physical activity are associated with the risk of future mortality, at least all-cause mortality in a somewhat selected group. Interpretation of the finding should be treated with caution due to the reliance on self-report and the possibility that residual confounding may underlie the associations. Because moderate-intensity physical activity is also beneficial to health, short physical activity questionnaires should include measures of such physical activity in the future.

Anti Inflammatory

Strenuous exercise induces an initial pro- and subsequent anti-inflammatory response, and it has been suggested that this may be one of the ways that regular exercise reduces chronic inflammation and therefore the risk of cardiovascular disease. However, public health recommendations emphasize moderate-intensity physical activity, and it is important to understand whether moderate-intensity exercise has a similar anti-inflammatory effect. Twelve sedentary male volunteers (age 54 ± 4 yr) completed two main trials, moderate-intensity exercise and rest (30 min at 50% maximal oxygen uptake vs. sitting, respectively). There were no significant changes in circulating neutrophils, lymphocytes, monocytes, or serum interleukin-6, interleukin-10, and C-reactive protein concentration over the 7 days following exercise. Similarly, lymphocyte adhesion to cultured endothelial cells and heme oxygenase-1 (HO-1) expression in lymphocytes and monocytes were not affected by walking at any time point. These results suggest that the long-term anti-inflammatory and antiatherogenic effects of regular moderate-intensity physical activity must be explained by something other than a profound net anti-inflammatory response to each exercise bout since a single bout of walking did not lead to a change in various markers of inflammation or lymphocyte adherence to cultured endothelial cells.

Barriers To Exercise

Background: The benefits of regular exercise are well recognized in type 2 diabetes subjects. However, a substantial proportion of patients don’t exercise at all. We aimed to enumerate the barriers to exercise in Type 2 Diabetes Mellitus (T2DM) patients and factors associated with these barriers. Methodology: We conducted a cross-sectional study of successive type 2 diabetes patients attending routine out-patient diabetes clinics in five tertiary care hospitals in Kolkata, India from 1st April,2017 to 31st March 2018. All patients who matched our study eligibility criteria were interviewed by diabetes care providers using a structured questionnaire modeled after a systematic review of similar studies but tuned to regional preferences. Besides demographic details, patient particulars and laboratory investigations, the questionnaire included 2 direct questions on possible barriers to exercise. The questions were grouped into five categories viz. environmental (4 questions), behavioral (9 questions), occupational (2 questions), physical inability (7 questions) and medical reason (1 question). Patients’ who didn’t meet the ADA-EASD recommended exercise (at least 150 minutes moderate intensity aerobic physical activity viz. brisk walking at 3-4 km-hr) were classified as non-exercisers. Results: The present study included a total of 1061 patients of which 617 were males versus 444 females. 636 (59.9%) were not doing physical activity as per current international standards. A substantial higher proportion of females (68.9%) did not exercised as compared to males (53.5%), which is statistically significantly higher, p<0.001. Insulin usage was found to be significantly associated to hamper exercise (p=0.017), physical activity being 8% lower (34.5% in insulin users versus 42.5% in non-insulin users). Male gender (OR-1.877, 95% CI=1.217-2.894, p=0.004) and doctor’s prior advice for exercise (OR-3.397, 95% CI=2.035-5.671, p<0.001) were found as significant predictors for increased physical activity. Conclusion: This study elaborates the need for awareness regarding possible barriers when counseling T2DM patients. Exercise remains one of the cheapest pillars of DM management, the benefits of which extend beyond glycemic control. However, as this study illustrates about 60% of patients with T2DM do not carry out the recommended exercise. This study also highlights the importance of physician advice regarding exercise. Behavioural causes seem to be the commonest barrier to exercise and hence strategies to target the same needs to be thought of.

Abstract Engagement in physical activity (PA) has well-documented benefits for delaying or preventing age-related diseases. Thus, it is important to study innovative ways to increase PA in the adult population. This symposium describes AgingPLUS, an ongoing trial that addresses three psychological mechanisms to increase adults’ PA: Negative views of aging (NVOA), low self-efficacy beliefs, and deficient goal-planning skills. The symposium also presents preliminary findings, based on a pre-pandemic subsample, on changes in explicit NVOA, implicit VOA, and changes in PA. Diehl et al. describe the theoretical background and study design of the ongoing RCT. This also includes the main study hypotheses. Rebok et al. present preliminary findings showing significant effects of the intervention on NVOA and frequency of moderate intensity exercise. Effects on physical function and accelerometry measures were not statistically significant in this subsample. Tseng et al. examined the effects of the intervention on two measures of implicit VOA: a lexical decision-making task (LDMT) and the Brief Implicit Association Test (BIAT). Findings showed that differences in post-intervention latencies on the LDMT were not statistically significant. Differences on post-intervention BIAT d scores also failed to be significant. Finally, Nehrkorn-Bailey et al. tested a multiple mediator model examining the mediational role of self-efficacy (SE) and exercise intention (EI) on PA. Results showed that Week 4 SE significantly mediated the effect of intervention condition to Week 8 anticipated PA engagement. Week 4 EI significantly mediated the effect of intervention condition on Month 6 PA engagement. Anticipated PA effects predicted subsequent involvement in PA.

ABSTRACT While the field of exercise oncology has substantially progressed in recent years, a significant void exists in the inclusion of and focus on minority patients diagnosed with cancer, particularly blacks and Hispanics. Blacks and Hispanics are less physically active, experience higher rates of comorbid conditions, and have poorer cancer prognosis when compared to white counterparts. Exercise prevents and reduces an array of health conditions, including cardiovascular disease, diabetes, obesity, and risk of certain cancers. However, black and Hispanic cancer survivors are underrepresented across exercise intervention trials. In this review, we discuss previous explorations among minority cancer survivors with a focus on exercise prescription, targeted outcomes, patient demographics, and barriers to exercise. We also discuss knowledge gaps and future directions necessary to progress the field of exercise oncology to include a more diverse cancer survivor cohort. In brief, we found few studies have evaluated the effect of exercise on physiologic health outcomes in black and Hispanic cancer survivors, with much research focused on psychosocial health. A majority of minority population-based research specifically targets the black breast cancer survivor population, with reported exercise-induced improvements observed in weekly physical activity, cardiorespira-tory fitness, muscle strength, quality of life, and fatigue. Minority cancer survivors also face unique challenges and barriers to exercise participation despite acknowledgement of the benefits with physical activity. Future investigations warrant explorations of exercise timing across the cancer continuum, inclusion of different types of cancer survivors, and novel exercise strategies with inclusion of culturally tailored educational and behavioral components.

BackgroundFew studies have prospectively evaluated the association of leisure-time physical activity (LTPA) with mortality in Asians, who are more susceptible to insulin resistance than their Caucasian counterparts.MethodsData from two large prospective cohort studies conducted in Shanghai were evaluated. After excluding participants who had a history of cancer, coronary heart disease or stroke at baseline, or who died within the first 3 years after study enrolment, 53 839 men and 66 888 women, followed for an average of 9.2 and 14.7 years, respectively, remained for the study.ResultsCompared with those who reported no exercise, a reduction in mortality with an HR of 0.86 (95% CI 0.80 to 0.93) was observed in those who regularly engage in moderate-intensity LTPA, even those who reported an LTPA level lower than the minimum amount recommended by the current physical activity guidelines (150 min or 7.5 metabolic equivalent hours per week). The association between moderate-intensity exercise and mortality followed a dose–response pattern until the amount of LTPA reached 3–5 times the recommended minimum level. A similar pattern of association was observed for cause-specific mortality due to cardiovascular disease (CVD), cancer or other causes.ConclusionRegular participation in moderate-intensity LTPA was associated with reduced mortality, particularly CVD mortality, even when the LTPA was below the minimum level recommended by current guidelines. Increasing the amount of moderate-intensity LTPA was associated with further risk reduction up to a potential threshold of 3–5 times the recommended minimum.

Glucose Dynamics

This paper aims to develop a data-driven model for glucose dynamics taking into account the effects of physical activity (PA) through a numerical study. It intends to investigate PA's immediate effect on insulin-independent glucose variation and PA's prolonged effect on insulin sensitivity. We proposed a nonlinear model with PA (NLPA), consisting of a linear regression of PA and a bilinear regression of insulin and PA. The model was identified and evaluated using data generated from a physiological PA-glucose model by Dalla Man et al. integrated with the uva/padova Simulator. Three metrics were computed to compare blood glucose (BG) predictions by NLPA, a linear model with PA (LPA), and a linear model with no PA (LOPA). For PA's immediate effect on glucose, NLPA and LPA showed 45–160% higher mean goodness of fit (FIT) than LOPA under 30 min-ahead glucose prediction (P < 0.05). For the prolonged PA effect on glucose, NLPA showed 87% higher FIT than LPA (P < 0.05) for simulations using no previous measurements. NLPA had 25–37% and 31–54% higher sensitivity in predicting postexercise hypoglycemia than LPA and LOPA, respectively. This study demonstrated the following qualitative trends: (1) for moderate-intensity exercise, accuracy of BG prediction was improved by explicitly accounting for PA's effect; and (2) accounting for PA's prolonged effect on insulin sensitivity can increase the chance of early prediction of postexercise hypoglycemia. Such observations will need to be further evaluated through human subjects in the future.
