This study compared the benefits of using a treadmill underwater or on land for obesity. Both methods of using the treadmill improved aerobic fitness and helped reduce body fat percentage. However, most notably, the underwater treadmill training appeared to produce greater gains in lean body mass. Loss of lean body mass, or sarcopenia, is one of the defining characteristics of aging. This study would support the idea that weight bearing exercise in water...

Nevada professor discovers new way to calculate body’s “Maximum Weight Limit.” Most of us are familiar with the term, Body Mass Index, or BMI, as an index to determine healthy body weight. But, calculating BMI involves a complex formula: weight in pounds is multiplied by 703, and then divided by height in inches squared. Charts ...

Younger people with pain look similar in terms of their disability to people who are two to three decades older without pain, according to a study published in this month’s issue of the Journal of the American Geriatric Society. The results of the study uncovered that people with pain develop the functional limitations classically associated ...

After two decades of improvement, the percentage of Americans without major heart disease risk factors is dropping, according to a report in Circulation: Journal of the American Heart Association. “From a preventive health point of view, it’s important that individuals achieve as many of these goals as possible, and it’s disappointing that less than 10 ...

Researchers in Hong Kong are reporting new evidence that green tea — one of the most popular beverages consumed worldwide and now available as a dietary supplement — may help improve bone health. They found that the tea contains a group of chemicals that can stimulate bone formation and help slow its breakdown. The beverage ...

Scientists have found that chemicals called endotoxins can inflame airways and trigger asthma. Endotoxins are shed by bacteria in household dust. Experts say better home hygiene, washing bed linens in hot water at least once a week, and using allergen-prevention pillow cases and mattress covers can reduce the risk of asthma attacks. Researchers say asthma and allergy triggers may be commonly found at home. That means there are things you can do to reduce the cause of your family's symptoms.

Radix Isatidis is one of the most commonly used and studied anti-influenza virus herbs in Chinese medicine. This study indicates that an extract of the herb is capable of preventing the virus from attaching itself to cells, a mechanism that may assist in preventing spread of the virus.

Scientists have discovered how bacteria fend off a wide range of antibiotics, and blocking that defense mechanism could give existing antibiotics more power to fight dangerous infections. Researchers at New York University said on Thursday that bacteria produce certain nitric oxide-producing enzymes to resist antibiotics. Drugs that inhibit these enzymes can make antibiotics much more potent, making even deadly superbugs like Methicillin-resistant Staphylococcus aureus or MRSA succumb, they said.

Growing evidence shows that exposure to lead in the environment is associated with cardiovascular disease, including increased risk of hypertension. However, those studies have looked at lead concentrations in blood, not bone lead, a better indicator of cumulative lead exposure over time. In a new study, researchers at the Harvard School of Public Health (HSPH) ...

A harmless shard from the shell of a common childhood virus may halt a biological process that kills a significant percentage of battlefield casualties, heart attack victims and oxygen-deprived newborns, according to research presented Sunday, September 6, 2009, at the 12th European meeting on complement in human disease in Budapest, Hungary. Introducing the virus’s shell ...
