Dr. Satyam Sarma MD Assistant Instructor, Cardiology University of Texas, Southwestern Medical Center Inst. for Exercise and Environmental Medicine 7232 Greenville Ave. Dallas TX 75231MedicalResearch.com Interview with: Dr. Satyam Sarma MD Assistant Instructor, Cardiology University of Texas, Southwestern Medical Center Inst. for Exercise and Environmental Medicine 7232 Greenville Ave. Dallas TX 75231 MedicalResearch.com: What are the main findings of the study? Dr. Sarma: The main findings of our study were that as we age or live a sedentary lifestyle, fat tends to accumulate in the muscle of the heart. The accumulation of myocardial lipids were linked to abnormalities in diastolic function. With increasing levels of fat, the left ventricle became less distensible and had impaired tissue relaxation.

MedicalResearch.com Interview with: Ronald J. Iannotti, PhD Prevention Research Branch, Eunice Kennedy Shriver National Institute of Child Health and Human Development, Bethesda, Maryland Trends in Physical Activity, Sedentary Behavior, Diet, and BMI Among US Adolescents, 2001–2009 MedicalResearch.com: What are the main findings of the study? Dr. Iannotti: Although average BMI percentile increased from 2001 to 2005 it did not increase from 2005 to 2009. This is consistent with some recent studies that suggest the increase in overweight and obesity may be leveling off. We suggest that we may be 'bending the curve'. During the same period, physical activity and consumption of fruits and vegetables increased while television watching and consumption of sweets and sweetened beverages decreased. We cannot say whether television watching was replaced with more time spent on computers but we did not find an increase in computer use from 2005 to 2009. (more…)

MedicalResearch.com Interview with: Pascale Mauriège, PhD, Division of Kinesiology PEPS, Room 2148, Laval University, Québec, Canada G1K 7P4 MedicalResearch.com: What are the main findings of the study? Answer: 1)    The impact of a 4-month brisk walking program (3 sessions/week of 45-min walking at 60% of heart rate reserve) on postmenopausal moderately obese (BMI=29-35 kg/m2) women’s perceived health, and more particularly the perceived ideal weight and stress level. 2)    The existence of a relationship between improvements in perceived ideal weight and fat mass reduction in the walking group. 3)    The lack of non respondents to our novel self-administered Short Perceived Health Questionnaire (SPHQ) that was completed within 2-3 min by all participant. 4)    The good reproductibility for five of six items of the SHPQ, and the validation of three questions against generic tools.

Jannique van Uffelen, PhD, MSc (epidemiology), MSc (human movement sciences), BHealth Senior Research Fellow Active Ageing INSTITUTE OF SPORT, EXERCISE & ACTIVE LIVING (ISEAL) VICTORIA UNIVERSITYMedicalResearch.com Interview with: Jannique van Uffelen, PhD, MSc (epidemiology), MSc (human movement sciences), BHealth Senior Research Fellow Active Ageing INSTITUTE OF SPORT, EXERCISE & ACTIVE LIVING (ISEAL) VICTORIA UNIVERSITY MedicalResearch.com: What are the main findings of the study? Answer: We examined the link between sitting-time and physical activity with current and future depressive symptoms in 8,950 mid aged women, who participated in the Australian Longitudinal Study on Women’s Health. Both high sitting-time and low physical activity levels were associated with higher risk of current depressive symptoms, and in combination, the risk further increased. Compared with women sitting ≤4 hours/day and meeting the physical activity recommendations of at least 150 minutes of moderate intensity activity per week, women who sat >7 hrs/day and who did no physical activity were three times as likely to have depressive symptoms. However, only lack of physical activity was associated with increased risk of future depressive symptoms, irrespective of sitting-time. Women who did no physical activity were 26% more likely to have future depressive symptoms than women meeting physical activity recommendations. (more…)

Thomas P. J. Solomon, Ph.D. Associate Professor of Biomedical Sciences Department of Biomedical Sciences | Cellular & Metabolic Research Section Panum Institute 4.5 | University of Copenhagen | Blegdamsvej 3B | 2200 Copenhagen N | DenmarkMedicalResearch.com Interview with: Thomas P. J. Solomon, Ph.D. Associate Professor of Biomedical Sciences Department of Biomedical Sciences | Cellular & Metabolic Research Section Panum Institute 4.5 | University of Copenhagen | Blegdamsvej 3B | 2200 Copenhagen N | Denmark MedicalResearch.com: What are the main findings of the study? Dr. Solomon: The main findings were that when impaired glucose tolerant and type 2 diabetic subjects underwent 3-4 months of regular aerobic exercise training, although the majority of subjects (86-90%) increased increased VO2max, lost weight, and increased insulin sensitivity, only around two-thirds of subjects improved glycemic control (HbA1c, fasting glucose, and 2-hour OGTT glucose). The novel finding was that the changes in glycemic control were congruent with changes in oral glucose-stimulated insulin secretion (GSIS). We also found that exercise training-induced changes in glycemic control were related to changes in GSIS (P0.05), but not insulin sensitivity. Furthermore, we found that training-induced improvements in glycemic control were largest in subjects with greater pre-training GSIS, i.e. in subjects with greatest beta-cell function. And, we noted that high pre-training hyperglycemia blunted exercise-induced improvements in beta-cell compensation for insulin resistance. (more…)

MedicalResearch.com Interview with: Michelle N. McDonnell, PhD Division of Health Sciences International Centre for Allied Health Evidence University of South Australia Adelaide, SA 5001 Australia.Michelle N. McDonnell, PhD Division of Health Sciences International Centre for Allied Health Evidence University of South Australia Adelaide, SA 5001 Australia. MedicalResearch.com: What are the main findings of the study? Dr. McDonnell: In this study, we asked people how many times a week they engaged in intense physical activity, enough to work up a sweat. People responded that they were physically active 0, 1-3 or 4 or more times a week. When we followed up these people for several years, those who did not do any vigorous exercise were 20% more likely to have a stroke, compared to those who exercised four or more times a week. However, when we adjusted these results for other risk factors, this attenuated the effect down to 14%  which was not statistically significant. We also noticed that people who exercised four or more times a week had less hypertension (high blood pressure), were less likely to be obese and less likely to have diabetes. Each of these things on their own reduces your risk of stroke, so when we adjust for that the association between physical activity and stroke is weaker (20% to 14%). So physical activity seems to have an effect on stroke risk by improving these other risk factors. (more…)

Answer: The main finding of this study is that reducing central adiposity and increasing fitness in men and women with Type 2 diabetes are key components for successfully improving glycemic control. A secondary finding of the study is that improvement in both central adiposity (reduction) and fitness (increasing) simultaneously; increase the likelihood of reducing HbA1c, one of the most widely used indicators of glucose control, and/or Type 2 diabetes medications.

MedicalResearch.com Author Interview with Dr. Koon Teo, MB, PhD Population Health Research Institute, Hamilton Health Sciences, McMaster University, Hamilton, Ontario, Canada MedicalResearch.com: What are the main findings of the study? Dr. Teo: In this study we examined the prevalence of smoking cessation or avoidance, eating a healthy diet and undertaking regular physical activities in nearly 8000 individuals who had previously experienced a coronary heart disease event or stroke, on average 5 years after their events. The individuals were recruited from over 600 communities in 17 countries with varying incomes and economic development.  We found that although these healthy lifestyle activities could reduce the risk of further heart or stroke events, about one fifth of individuals continued to smoke, only one third undertook regular leisure or work related physical activities and about two fifths ate a healthy diet.
