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.

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.

Media Message

Background:Women’s understanding of “moderate-intensity” physical activity (MPA) as presented in the media is not well-understood. This study assessed whether women who are presented a mass-media message about MPA can demonstrate a moderate-intensity walking pace without practicing this pace first.Methods:Insufficiently active women (n = 75, age 40 ± 12 years, 76% White) were shown a mass-media description of a MPA recommendation. Forty-one were randomized to also practice a moderate-intensity (55%−70% of maximum heart rate) walk. One month later, participants were asked to demonstrate a 10-minute moderate-intensity walk. Groups were compared on the proportion of participants who walked ≥10 minutes at a moderate intensity.Results:At posttest, more participants who received practice at baseline walked at a moderate-intensity ≥10 minutes than those who received no practice (P < .05).Conclusion:To understand MPA, it is not enough to simply hear and read a description of MPA. It is essential to practice MPA.

Perceived Access

Background: Approximately 80% of pregnant women in the US do not meet the CDC recommendation for moderate-intensity physical activity. The built environment is a key contributor to physical activity (PA) behavior. However, there may be a disconnect between physical attributes of the built environment and perceived access to an environment that supports PA. Use of a geographic information system (GIS) to objectively measure aspects of the built environment can yield important information about proximity of resources for supporting PA. We evaluated concordance of perceived access to multi-use bike paths (MUBP) and parks in a population of pregnant women. We also examined demographic characteristics associated with concordance between perceived and actual supports for PA. Methods: A population of 155 pregnant women in the greater Columbus, OH area reported perceptions of access to environmental supports within their neighborhood (defined as 0.5 mi. radius/ 10 min. walk) and community (10 mi. radius/ 20 min. drive), along with self-reported PA information. Addresses were abstracted from medical records and geocoded. Within ArcMap 10.2.2 (ESRI, Redlands, CA), buffers at distances of 0.5, 1, and 10 miles were created around MUBP and parks, respectively. Respondents were classified as “near” a resource if their address fell within those buffers. Logistic regression was used to examine the association between concordance of self-report with objectively measured proximity and demographic factors associated with higher concordance. Results: Within the study population of 155, 12% and 28% of women lived within 0.5 and 1 mile of a dedicated MUBP, respectively. More women lived within close proximity to a park (46% within a 0.5 mile radius, and 69% were within a 1 mile radius). The discordancy for parks ranged from 9.68%-49.03%, and from 16.77%-76.13% for MUBP. Concordance of report of parks within the community was higher among non-Hispanic white women (OR=4.2 [1.1, 15.3]) and that concordance or over-reporting of access to parks within the community was higher among married women (OR=5.3 [1.3, 21.5]). There were no significant differences in self-reported PA or changes in PA, however women living within 1 mile of a park reported more minutes of moderate-to-vigorous PA. A greater percentage of those with access reported increasing or maintaining levels of moderate PA from before pregnancy through the third trimester. Conclusions: The discordance between perception of access and objectively measured proximity to MUBP and parks suggests a substantial portion of women are not aware of their availability, or do not perceive them as relevant factors in influencing their PA behaviors during pregnancy. It may be that physical proximity is not a major driver in perceived access. Characteristics of the built environment, such as safety or social environment, may play a larger role in influencing PA behaviors.

Poor Outcomes

Purpose Obesity is associated with poor outcomes in women with operable breast cancer. Lifestyle interventions (LIs) that help women reduce their weight may improve outcomes. Patients and Methods We conducted a multicenter randomized trial comparing mail-based delivery of general health information alone or combined with a 24-month standardized, telephone-based LI that included diet (500 to 1,000 kcal per day deficit) and physical activity (150 to 200 minutes of moderate-intensity physical activity per week) goals to achieve weight loss (up to 10%). Women receiving adjuvant letrozole for T1-3N0-3M0 breast cancer with a body mass index (BMI) ≥ 24 kg/m2 were eligible. Weight was measured in the clinic, and self-report physical activity, quality-of-life (QOL), and diet questionnaires were completed. The primary outcome was disease-free survival. Accrual was terminated at 338 of 2,150 planned patients because of loss of funding. Results Mean weight loss was significantly (P < .001) greater in the LI arm versus the comparison arm (4.3 v 0.6 kg or 5.3% v 0.7% at 6 months and 3.1 v 0.3 kg or 3.6% v 0.4% at 24 months) and occurred consistently across strata (BMI 24 to < 30 v ≥ 30 kg/m2; prior v no prior adjuvant chemotherapy). Weight loss was greatest in those with higher baseline levels of moderate-intensity physical activity or improvement in QOL. Hospitalization rates and medical events were similar. Conclusion A telephone-based LI led to significant weight loss that was still evident at 24 months, without adverse effects on QOL, hospitalizations, or medical events. Adequately powered randomized trials with cancer end points are needed.

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.
