The Impact

AbstractRegular moderate intensity physical activity and habitual diet providing no more than one third of energy from fats have been recommended for the prevention of atherosclerotic diseases. The background for these guidelines is the key role of plasma lipids. However, the importance of thrombogenesis in acute myocardial infarction has become obvious during the last decade. Hyperlipidaemia and excess of adipose tissue increase platelet aggregability and blood coagulation, and decrease fibrinolysis. Both regular physical activity and dietary fat reduction decrease blood lipids and body fat thereby diminishing the risk of thrombosis. Currently, data on interactions between physical activity and diet on haemostasis are scarce, and the few studies available have not demonstrated additional effects when these two lifestyle modifications have been combined. This paper is restricted only to studies using controlled randomized design. Regular moderate intensity physical activity as well as diet rich in omega-3 fatty acids decrease platelet aggregability. The effects of regular physical activity on plasma fibrinogen remain contradictory, while the impact of diet is even less clear. Plasminogen activator inhibitor-1, a possible link between insulin resistance syndrome and coronary heart disease, may decrease due to physical training or low fat diet. It can be hypothesized that moderation in physical activity and diet carries a more powerful impact on blood coagulation and fibrinolysis than either lifestyle modification alone. Studies focusing on the interactions of regular moderate physical activity and fat-modified diet are needed in efforts to optimize the preventive actions by lifestyle changes.

Background: Glucose concentrations in a fasted and during a glucose challenged state rely on different mechanisms for regulation. In a fasted state, hepatic regulation of glucose is important; while in a glucose challenged state, muscle glucose disposal becomes more important. Evidence suggests that physical activity of moderate or higher intensities can increase muscle glucose disposal during an insulin-stimulated state, but has less effect on hepatic insulin sensitivity. The purpose of this study was to examine the associations between glucose concentrations (fasting and after an oral glucose ingestion) and minutes of physical activity at moderate- and vigorous-intensity in a large population. Methods: The sample included 2,807 adults (47.4% male and 52.6% female) aged 18-80 years who participated in the National Health and Nutritional Examination Surveys (NHANES) from 2013-2014 and who did not take any diabetic medications. Minutes being physically active at moderate- and vigorous-intensities during work, and recreationally, were collected using the Physical Activity Questionnaire, which was based on the Global Physical Activity Questionnaire. Moderate-intensity physical activity was defined as any activity that caused a small increase in breathing or heart rate, while vigorous-intensity physical activity was defined as large increases in breathing or heart rate. Both intensities had to be performed for a minimum of 10 continuous minutes. Plasma glucose concentrations at fasting and 2 hours after consumption of a drink containing 75g glucose (2-hour glucose) were determined. Pearson product correlations were performed for analysis. Results: The population had 141±133 (mean±SD) minutes of moderate-intensity physical activity during work and 63±56 minutes recreationally, as well as 174±156 minutes of vigorous-intensity physical activity during work and 77±56 minutes recreationally. Minutes of vigorous-intensity physical activity performed during work was associated with 2-hour plasma glucose concentrations (r=0.15; p=0.045); this association was not affected after adjusting for age, race, and sex (p=0.049), but was no longer significant after BMI was also adjusted (p=0.059). Recreational or total minutes of vigorous-intensity physical activity, and moderate-intensity physical activity was not associated with 2-hour glucose (p>0.20). Additionally, none of the physical activity minutes was associated with fasting glucose (p>0.27). Conclusion: Self-reported vigorous-intensity physical activity during work was positively associated with 2-hour glucose, but not fasting glucose. The results are surprising. Further studies with objective physical activity measures are needed to examine the associations with fasting and 2-hour glucose.

Introduction: Leisure time physical activity (LTPA) has been consistently associated with a lower risk of stroke across several populations. Less is known however about how changes over the life-time in physical activity may influence the risk of stroke. We examined the association of changes in engaging in moderate and strenuous physical activity with risk of stroke in the California Teachers Study. Methods: The California Teachers Study is a prospective cohort study established in 1995. Baseline LTPA was obtained using a questionnaire outlining time spent in moderate (brisk walking for example) and strenuous (swimming and running for example); the same questionnaire was repeated in 2005-6. We defined the exposure as engaging in any activity for at least 15 minutes per week (any) in the second questionnaire when not engaging in any on the first questionnaire, with the reference being no change or a decline in activity between both. Multi-variable Cox models were constructed to examine the association of the change in LTPA with risk of stroke. Separate models were created for moderate and strenuous activity. Results: There were a total of 61,256 participants with two LTPA questionnaires available separated by 10 years. A total of 3,111 participants increased their level of moderate activity, 11,744 remained active in both, 2,760 declined from the first to the second questionnaire, while 2,508 reported no activity in both. There were 987 (709 ischemic, 221 hemorrhagic, 247 deaths) strokes after the second questionnaires (mean follow up 6.5 years). In multi-variable models increasing any moderate intensity from none from the two questionnaires, versus no change or decline in activity, was associated with a lower risk of all stroke (adjusted HR 0.83, 95% CI 0.72-0.95). We found no associations of changes in strenuous LTPA with risk of stroke (adjusted HR 0.99, 95% CI 0.83-1.17). The associations were statistically significant for ischemic stroke (adjusted HR 0.75, 95% CI 0.64-0.89) but not hemorrhagic stroke (adjusted HR 0.94, 95% CI 0.72-1.25). Conclusion: Improving or maintaining moderate intensity physical activity is associated with a lower risk of stroke, while changes in strenuous activity is not.

People may be more or less vulnerable to changes in self-control across the day, depending on whether they believe willpower is more or less limited. Limited willpower beliefs might be associated with steeper decreases in self-control across the day, which may result in less goal-consistent behaviour by the evening. Community members with health goals (Sample 1; N = 160; 1814 observations) and students (Sample 2; N = 162; 10,581 observations) completed five surveys per day for one to three weeks, reporting on their recent physical activity, snacking, subjective state, and health intentions. In both samples, more limited willpower beliefs were associated with less low- and moderate-intensity physical activity, particularly later in the day. Limited willpower beliefs were also associated with more snacking in the evenings (Sample 1) or overall (Sample 2). These behavioural patterns were mediated by differential changes in self-efficacy and intentions across the course of the day (in Sample 1), and the above patterns of low- and moderate-physical intensity held after controlling for related individual differences, including trait self-control and chronotype (in Sample 2). Overall, more limited willpower theories were associated with decreasing goal-consistent behaviour as the day progressed, alongside decreasing self-efficacy and weakening health-goal intentions.

Abstract Many nurses, patients, and families continue to believe that physical activity increases the risk of falling. The purpose of this study was to test the hypothesis that residents who are exposed to Function Focused Care for Assisted Living (FFC-AL-EIT) and engage in moderate levels of physical activity would not be more likely to fall. This was a secondary data analysis using data from the first two cohorts of the FFC-AL-EIT study. The study included 508 residents the majority of whom were female (70%), white (97%), with a mean age of 87.72 (SD=7.47). Those who engaged in more moderate intensity physical activity were 1% less likely to fall (b = -.01, Wald =6.13, p =.01). There was no association between exposure to function focused care and falling (Beta =.41, Wald =2.35, p=.13). Further, engaging in moderate level physical activity was noted to be slightly protective of falling.

There is an inverse relationship between physical activity and weight gain. However, additional research is needed to quantify the amount of physical activity required to prevent weight gain in different populations, improve the way we convey physical activity recommendations to the public, and help the individuals increase their physical activity. Although physical activity does not appear to contribute significantly to weight loss, it is critical for maintenance of weight loss. Available data are consistent in that 60–90 min/day of moderate-intensity physical activity is required to maintain a significant weight loss. Although there is agreement about the need for high levels of physical activity to maintain weight loss, there is a need for more research to understand why physical activity is critical for weight loss maintenance. Finally, additional research is needed to determine whether there is an optimal level of physical activity below which it is difficult for most people to achieve a balance between energy intake and expenditure at a healthy body weight. The increasing prevalence of obesity may reflect the fact that the majority of the population has fallen below such a level of physical activity.

Background:In 2005, investigators convened by the National Cancer Institute recommended development of standardized protocols for accelerometer use and reporting decision rules in articles. A literature review was conducted to document accelerometer methods and decision rule reporting in youth physical activity articles from 2005−2010.Methods:Nine electronic databases identified 273 articles that measured physical activity and/or sedentary behavior using the most-used brand of accelerometer (ActiGraph). Six key methods were summarized by age group (preschool, children, and adolescents) and trends over time were examined.Results:Studies using accelerometers more than doubled from 2005−2010. Methods included 2 ActiGraph models, 6 epoch lengths, 6 nonwear definitions, 13 valid day definitions, 8 minimum wearing day thresholds, 12 moderate-intensity physical activity cut points, and 11 sedentary cut points. Child studies showed the most variation in methods and a trend toward more variability in cut points over time. Decision rule reporting improved, but only 54% of papers reported on all methods.Conclusion:The increasing diversity of methods used to process and score accelerometer data for youth precludes comparison of results across studies. Decision rule reporting is inconsistent, and trends indicate declining standardization of methods. A methodological research agenda and consensus process are proposed.
