14 Oct HDL Function: Improved with Strength Training, Even in Overweight
MedicalResearch.com Interview with: Christian K. Roberts Exercise and Metabolic Disease Research Laboratory, Translational Sciences Section, School of Nursing University of California, Los Angeles, CA MedicalResearch.com: How would you best summarize the main findings/results of this study? Answer: Our main finding was that HDL functioned better in its antioxidant role in subjects who participated in resistance exercise training (i.e. weight training) a minimum of 4 days a week, regardless of their weight—one group was lean (BMI <25) and the other overweight/obese (BMI >27) —than those who didn’t exercise (overweight, BMI >27, and untrained). In addition, HDL had similar effectiveness as an antioxidant in the overweight-trained group as in the as lean-trained group. Although indices of weight were associated with dysfunctional HDL, differences in fitness may be a better measure of who has healthier functioning HDL.11 Sep Effects of Positive Mood and Exercise on Mortality and Hospitalizations

MedicalResearch.com: What are the main findings of the study?
Answer: The main finding was that we found a significant relation between positive affect and mortality, and that exercise explained this relationship. With respect to the second outcome, hospitalization, we found a significant relation between positive affect and hospitalization, a significant relation between positive affect and hospitalization, but exercise did not mediate this relationship.
03 Sep Postmenopausal Women: Impact Brisk Walking
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.24 Aug Diabetes: Exercise Improves Glycemic Control if Pancreatic Beta-Cell Function Remains
MedicalResearch.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.
26 Jul Stroke Risk and Physical Activity Frequency

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.
31 May Exercise Training and Changes in HbA1c, Body Fat and Fitness
MedicalResearch.com eInterview with
Martin Sénéchal, Ph.D.
Postdoctoral Researcher
The Manitoba Institute of Child Health
University of Manitoba
511E- 715 McDermot Ave Winnipeg, Manitoba
MedicalResearch.com: What are the main findings of the study?
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.
19 Mar Effect of Aerobic Exercise (Walking) Training on Functional Status and Health-related Quality of Life in Chronic Stroke Survivors
MedicalResearch.com Interview with Carron D. Gordon, PhD Section of Physical Therapy, University of the West Indies, Mona, Box 126, Kingston 7, Jamaica, West Indies MedicalResearch.com: What are the main findings of the study? Dr. Gordon: The walking group showed a 17.6% improvement in distance walked in six minutes (measure of endurance) compared to 4% in the control group and 16.7% improvement in SF36-Physical Component (health-related quality of life) compared to 2.6% in the control group.08 Sep Aerobic exercise may reduce the risk of dementia
ROCHESTER, Minn. - Any exercise that gets the heart pumping may reduce the risk of dementia and slow the condition's progression once it starts, reported a Mayo Clinic study published this month in Mayo Clinic Proceedings. Researchers examined the role of aerobic exercise in preserving cognitive abilities and concluded that...
