High-intensity interval training combining rowing and cycling improves insulin sensitivity, body composition and cardiorespiratory fitness in obesity and type 2 diabetes

A new study found that high-intensity interval training (HIIT) combining cycling and rowing improves insulin sensitivity and reduces blood sugar levels in individuals with obesity and type 2 diabetes. The study also showed improvements in body composition, including a reduction in fat mass and an increase in muscle mass.

Legacy

A new study led by UT Southwestern scientists suggests that breastfeeding changes the body's insulin sensitivity, particularly in highly insulin-sensitive organs like the liver and fat tissue. This increase in insulin sensitivity may provide a buffer against insulin resistance even decades later, lowering the risk of Type 2 diabetes.

The insulin under the influence of light

Scientists uncover how light influences insulin sensitivity and metabolic homeostasis, shedding light on the circadian rhythms' impact on diabetes. The study suggests that taking into account time of day can help patients better manage their treatment and reduce risks associated with daily insulin injections.

Train harder, for less time

A six-week high-intensity resistance training program improved insulin sensitivity by 16% and increased muscle size and strength in overweight men. The study suggests that short sessions of exercise to exhaustion are equally effective as longer sessions, making it a time-efficient way to improve health outcomes.

Children's Colorado researchers link sleep health to insulin resistance in obese teens

Researchers at Children's Hospital Colorado found that shorter sleep duration, later weekday bedtimes, and poor circadian timing were linked to reduced insulin sensitivity in adolescents with overweight or obesity. The study suggests potential benefits of improving sleep health through interventions like delayed school start times.

Breakthrough in battle against type 2 diabetes

Experts from the University of Stirling have made a breakthrough in understanding how people respond to lifestyle treatment for preventing Type 2 diabetes. A new genomic signature has been discovered that indicates improved insulin sensitivity in individuals whose Type 2 diabetes status improves following a treatment intervention.

Study appears first in the nation to examine the impact of vitamin K supplements on the cardiovascul

Researchers are enrolling 60 obese children in an eight-week study to examine the impact of vitamin K supplements on their cardiovascular health. The study aims to determine whether vitamin K can improve insulin sensitivity and reduce lipid levels in the blood, potentially reducing the risk of diabetes and cardiovascular disease.

More evidence that 'healthy obesity' may be a myth

A recent study challenges the concept of 'healthy obesity,' revealing nearly identical gene expression changes in obese individuals with varying levels of insulin sensitivity. The research suggests that vigorous health interventions may be necessary for all obese individuals, regardless of their metabolic health status.

Vanderbilt study finds erectile dysfunction drug may benefit patients at risk for diabetes

A Vanderbilt study found that sildenafil improves insulin sensitivity in people at risk for diabetes, potentially reducing the risk of developing type 2 diabetes. The researchers discovered that sildenafil inhibits an enzyme called phosphodiesterase 5, resulting in relaxation of smooth muscle and increased blood flow.

Insulin resistance linked to a human gene variant

A new study identifies N-acetyltransferase 2 as a key gene variant linked to insulin resistance, increasing the risk of type 2 diabetes and cardiovascular disease. Inhibition of NAT2 in a mouse model decreased insulin sensitivity, highlighting its role in complex diseases.

Insulin differs between ethnicities, study finds

A new study found that ethnic differences significantly impact insulin response, with East Asians showing improved insulin sensitivity but poorer insulin release. Healthy individuals of all ethnicities maintained normal glucose levels but did so differently, with some groups releasing more or less insulin in response to changes.

Getting enough sleep could help prevent type 2 diabetes

A study by LA BioMed found that men who get more sleep on the weekend can improve their insulin sensitivity, reducing their risk of developing type 2 diabetes. The research, conducted over six months, involved 19 non-diabetic men who slept an average of 6.2 hours per night during the week and caught up on sleep on weekends.

Resveratrol falls short in health benefits

Single gene cause of insulin sensitivity may offer insight for treating diabetes

A study published in the New England Journal of Medicine reveals that mutations in the PTEN gene can improve metabolism and increase insulin sensitivity in people with Cowden syndrome. The researchers found that those with Cowden syndrome had higher levels of obesity, but the extra weight was caused by extra fat storage, not muscle mass.
