Could coffee be the secret to fighting obesity?

Scientists from the University of Nottingham have discovered that drinking a cup of coffee can stimulate ‘brown fat’, the body’s own fat-fighting defenses, which could be the key to tackling obesity and diabetes. The pioneering study, published today in the journal Scientific Reports, is one of the first to be carried out in humans to find components which could have a direct effect on ‘brown fat’ functions, an important part of the human body which plays a key role in how quickly we can burn calories as energy. Brown adipose tissue…

A short bout of exercise enhances brain function

Most people know that regular exercise is good for your health. New research shows it may make you smarter, too. Neuroscientists at OHSU in Portland, Oregon, working with mice, have discovered that a short burst of exercise directly boosts the function of a gene that increases connections between neurons in the hippocampus, the region of the brain associated with learning and memory. The research is published online in the journal eLife. “Exercise is cheap, and you don’t necessarily need a fancy gym membership or have to run 10 miles a day,”…

Extreme exercise can strain the heart without causing permanent damage

Researchers have found no evidence of elevated cardiac risk in runners who completed a 24-hour ultramarathon (24UM), despite the transient elevation of blood biomarkers that measure cardiac health. According to the study in the journal Heliyon, published by Elsevier, trained runners were more likely than their novice counterparts to experience raised levels, reflecting the greater cardiac load and pituitary-adrenocortical response to extremely strenuous exercise. “Experienced runners performed with greater intensity and speed, which placed strains on their hearts. Novice runners ran with less intensity, which resulted in lower cardiac biomarker levels,”…

Performance-enhancing bacteria found in the microbiomes of elite athletes

New research has identified a type of bacteria found in the microbiomes of elite athletes that contributes to improved capacity for exercise. These bacteria, members of the genus Veillonella, are not found in the guts of sedentary people. By taking a closer look at the bacteria, the researchers from Joslin Diabetes Center determined Veillonella metabolizes lactic acid produced by exercise and converts it into propionate, a short chain fatty acid. The human body then utilizes that propionate to improve exercise capacity. The results were reported today in Nature Medicine. “Having increased…

The gym proving too expensive or time consuming?

How much do you exercise? Government guidelines suggest that, in order to stay healthy, adults should perform at least 150 minutes of moderate aerobic activity every week — that’s exercise that gets your breathing and heart rate up. A new study, published in The Journal of Physiology investigated a home-based high-intensity interval training (Home-HIT) programme and studied its benefits for clinically obese individuals with an elevated risk of heart disease. Previous research has demonstrated that under controlled laboratory conditions, you can get the same benefits from three 20-minute exercise sessions, as from…

Low-carb diet may reduce diabetes risk independent of weight loss

A low-carb diet may have benefits for people at risk of developing type 2 diabetes even if they don’t lose any weight, a new study suggests. Researchers at The Ohio State University wanted to know what happens to obese people with metabolic syndrome, a precursor to diabetes, when they eat a diet low in carbohydrates but don’t shed any pounds. They found that more than half of study participants no longer met the criteria for metabolic syndrome immediately following a four-week low-carb diet. The new study included 16 men and…

Upbeat music can sweeten tough exercise

New research coming out of UBC’s Okanagan campus demonstrates that upbeat music can make a rigorous workout seem less tough. Even for people who are insufficiently active. Matthew Stork is a postdoctoral fellow in the School of Health and Exercise Sciences. He recently published a study examining how the right music can help less-active people get more out of their workout — and enjoy it more. High-intensity interval training (HIIT) — brief, repeated bouts of intense exercise separated by periods of rest — has been shown to improve physical health…

Researchers learned how to better combat muscle loss during space flights

A new research study from The University of Texas Medical Branch at Galveston has even more recorded how muscles are affected by decreased gravity conditions throughout space flight missions and uncovered how exercise and hormone treatments can be tailored to reduce muscle loss for private space tourists. The findings are readily available in PLOS One. NASA has recently revealed that it will enable private citizens to check out the International Space Station. The growing number of area tourists highlights the requirement to understand the impact of decreased gravity on the…

Exercise may have different impacts in the morning and night

Researchers from the University of Copenhagen have actually found out that the result of workout might differ depending upon the time of day it is performed. In mice they show that exercise in the early morning results in an increased metabolic action in skeletal muscle, while workout later on in the day increases energy expenditure for an extended time period. We probably all understand how important a healthy circadian rhythm is. Insufficient sleep can have severe health effects. However scientists are still making new discoveries validating that the body’s circadian…
