(Press-News.org) ROCKVILLE, Md.— New research reveals that moderate to vigorous physical activity in the evening for sedentary adults with overweight and obesity is most beneficial in lowering daily blood sugar levels, according to a study published in Obesity, The Obesity Society’s (TOS) flagship journal.
Experts explain that it has been well established that moderate to vigorous physical activity enhances glucose homeostasis in adults with overweight and obesity who are at higher risk of developing insulin resistance. However, little is known about the optimal timing of moderate to vigorous physical activity to improve daily blood glucose control.
“Our results highlight the importance of the field of precision exercise prescription. In clinical practice, certified sports and medical personnel should consider the optimal timing of the day to enhance the effectiveness of the exercise and physical activity programs they prescribe,” said Jonatan R. Ruiz, PhD, professor of physical activity and health, Department of Physical and Sports Education, Faculty of Sport Sciences-Sport and Health University Research Institute (iMUDS), University of Granada, ibs.Granada and CIBEROBN, Spain. Ruiz is one of two corresponding authors of the study with predoctoral researcher Antonio Clavero-Jimeno from the same research center.
Data for the study was used from baseline examinations from a multi-center randomized controlled trial conducted in Granada and Pamplona, Spain. The aim of the trial was to study the efficacy and feasibility of time-restricted eating on visceral adipose tissue (primary outcome), body composition and cardiometabolic risk factors in adults with overweight and obesity.
A total of 186 adults with an average age of 46 years and a body mass index of 32.9 kg/m2 with overweight or obesity participated in the cross-sectional study. The physical activity and glucose patterns of participants were simultaneously monitored over a 14-day period using a triaxial accelerometer worn on the non-dominant wrist and a continuous glucose-monitoring device.
The study’s researchers classified the volume of moderate to vigorous physical activity accumulated for each day. Categories included inactive (if no activity was accumulated), and as ‘morning,’ ‘afternoon’ or ‘evening’ if more than 50% of the moderate to vigorous physical activity minutes for that day were accumulated between 6 a.m. to noon, noon to 6 p.m., 6 p.m. to 12 p.m., or as ‘mixed’ if none of the defined time windows accounted for greater than 50% of the moderate to vigorous physical activity for that day.
Results showed that accumulating greater than 50% of moderate to vigorous physical activity in the evening was associated with lowering day, night and overall blood glucose levels compared with being inactive. This association was stronger in those participants with impaired glucose regulation. The pattern of these associations was similar in both men and women.
“As the field moves towards individualized exercise prescriptions for different chronic conditions, this study now provides additional insights beyond just telling patients to ‘move more,’ but instead to move as often as possible and to prioritize afternoon-to-evening movement when feasible for glucose regulation,” said Renee J. Rogers, PhD, FACSM, senior scientist, Division of Physical Activity and Weight Management, University of Kansas Medical Center. Rogers was not associated with the research.

ROCKVILLE, Md.— Individuals treated with anti-obesity medications generally experience reduced appetite, which typically leads to reduced food intake. As a result, dietary quality becomes more important because nutritional needs must be met within the context of eating less. To improve this process, medical experts have developed a list of evidence-based nutritional recommendations to assist clinicians treating patients with anti-obesity medications, according to a review published in the journal Obesity, The Obesity Society’s (TOS) flagship journal.

Boys are good at math, girls not so much? A study from the University of Zurich has analyzed the social mechanisms that contribute to the gender gap in math confidence. While peer comparisons seem to play a crucial role for boys, girls’ subjective evaluations are more likely to be based on objective performance.
Research has shown that in Western societies, the average secondary school girl has less confidence in her mathematical abilities than the average boy of the same age. At the same time, no significant difference ...
Carbon capture and utilization technologies for the conversion of carbon dioxide into carboxylic acids have garnered attention recently, with researchers from Tokyo Tech recently demonstrating a biocatalyzed carboxylation reaction of not only natural substrate, pyruvate, but also unnatural one, 2-ketoglutarate, using Thermoplasma acidophilum NADP+- malic enzyme under mild reaction conditions. The proposed strategy can be tailored for the selective synthesis through carbon dioxide fixation reactions.
Removing the excess carbon dioxide (CO2) from the environment is not the end goal of the decarbonization process necessary to ...
Among US veterans diagnosed with lung cancer through the Veterans Health Administration healthcare system, those who underwent screening before diagnosis were more likely to be diagnosed with earlier stage disease and had a higher cure rate than those who had not been screened. The findings come from an observational study published by Wiley online in CANCER, a peer-reviewed journal of the American Cancer Society.
Lung cancer is the leading cause of cancer deaths worldwide, and most patients are diagnosed at ...

Abnormal blood flow in the aorta is linked to inflammation and breakdown of the vessel wall in conditions where the aorta is dilated. This is shown in a study led by researchers at Linköping University. The findings can contribute to better diagnosis and open up new ways to assess the risk of serious and usually fatal complications, such as rupture of the aorta.
All blood in the body passes through the heart about once a minute. With every heartbeat, blood from the heart is pumped up into the aorta.
Dilation can occur in all parts ...
Health services should teach patients with eating disorders psychosocial skills to help more people recover and avoid relapse, according to an expert.
Anorexia, bulimia and other eating issues affect millions of people, and eating disorder specialist Bethany Crowley warns that eating disorders are often misunderstood. She suggests a more integrated approach to treating people is needed, to focus on the whole person rather than just the disordered eating.
Quieting negative thoughts, learning to cope with emotional triggers and practicing self-compassion are among nine key skills outlined by the therapist in a new book.
An Integrative Approach to Treating Eating ...
Background
Fusion energy is that released when two light nuclei combine to form a single heavier one (nuclear fusion reaction). Fusion energy-based power generation (fusion power plant) uses the energy generated when deuterium and tritium combine to form helium. A nuclear fusion reaction does not produce carbon dioxide. In addition, since it is possible to extract deuterium and tritium from the sea water, fusion energy is regarded as a sustainable energy source, and research into its practical application has been progressing rapidly ...
A glowing marker dye that sticks to prostate cancer cells could help surgeons to remove them in real-time, according to a study funded by Cancer Research UK.
Cancer Research UK-funded scientists, based at the Nuffield Department of Surgical Sciences and the Department of Oncology, University of Oxford, Oxford University Hospitals and Oxford NIHR Biomedical Research Centre used a fluorescent dye attached to a special marker molecule to give medics a “second pair of eyes” during surgery for prostate cancer.
Twenty-three men with prostate cancer were injected with the marker dye before undergoing prostate removal surgery. The marker dye found areas of cancerous tissue ...
ALS patients received better care if they were treated by a neurologist, a new study published in PLOS One has found.
But researchers found that Black, older and socially disadvantaged ALS patients were less likely to see a neurologist, raising concerns about equity in treating the deadly disease.
Patients who were treated by neurologists were more likely to receive interventions endorsed by the American Academy of Neurology.
“This study highlights the importance of neurologist care for ALS patients and the need to overcome barriers and provide care that is more equitable for ALS patients,” ...
