Exercise lengthens your life - even if you're overweightAdd this to the list of reasons why exercise is good for you: A new study says 150 minutes a week of moderate-intensity, leisure time exercise is associated with roughly 3.4 years added to a person's life. Researchers from the National Cancer Institute, Harvard Medical School, and other organizations analyzed six different prospective cohort studies of more than 632,000 people ages 40 and older. The studies had a median follow-up period of 10 years, with roughly 82,000 reported deaths. Regular, moderate intensity exercise was associated with an increased life expectancy, even when the person exercising had an unhealthy Body Mass Index (BMI). Dr. I-Min Lee, a professor of medicine at Harvard Medical School and the senior author of the study, says that not exercising but having a healthy weight was associated with 3.1 fewer years of life, compared to obese people who were active. Conversely, people who exercised 150 minutes a week and had a healthy BMI gained an extra 7.2 years of life. FULL POST

You can be fat AND fit, researchers say"I'm in shape," a friend of mine repeatedly quips at the gym. "Round is a shape." It's an old joke, but there may be some truth to it. A new study published this week in the European Heart Journal shows it is possible to be both obese and healthy. "It is well known that obesity is linked to a large number of chronic diseases such as cardiovascular problems and cancer," lead study author Dr. Francisco Ortega said in a statement. "However, there appears to be a sub-set of obese people who seem to be protected from obesity-related metabolic complications."

Most kids don't get enough PE, says studyMost schools in the United States are not offering children the suggested amount of physical education, according to a new study. The study, conducted by Bryan McCullick, a kinesiology professor at the University of Georgia, examined all 50 of the United States and found six states where elementary schools followed recommended physical education guidelines. Two states followed the guidelines at the middle school level, and no states had strong enough regulations at the high school level. Several other states had some form of physical education requirement, but they did not reach a threshold the researchers thought was appropriate. What’s the issue? McCullick says schools may be cutting time for physical education to increase time for other subjects, in the hope of raising standardized test scores.  Runners should pay attention to their bodies when training and may need to take days of rest.

Longer commutes may steal health and fitnessAnybody who has a long daily commute knows the frustration of sitting in traffic with nothing to do but wait. Now, a study suggests that long commutes can take away more than just precious time - they also negatively impact your fitness and health. Previous research has linked longer commutes with obesity. But this new research is believed to be "the first study to show that long commutes can take away from exercise time,” explained lead investigator Christine M. Hoehner of Washington University in St. Louis. Long commutes are associated with "higher weight, lower fitness levels and higher blood pressure, all of which are strong predictors of heart disease, diabetes and some cancers,” she said.

Open-water swimming tips from the prosEditor's note: In this post from Triathlete magazine, pros Julie Dibens and James Cunnama share five rules of a successful open-water swim. Rule 1: Keep your space “In the pool, you’re in a lane by yourself. In a triathlon, you have 50, 100, even 200 people trying to get to the same spot. It’s hard to stay in a straight line. You have to figure out how to make the most of it and get a draft,” says Dibens. “Don’t hang on to a boat, kayak or buoy [before a deep water start],” adds Cunnama. “It doesn’t make a good start because something is in your way. It’s hard to get a good kick in. Get some space.”

Red flag found for imminent heart attackMost heart attacks hit without warning – when a blister plaque on the blood vessel wall ruptures. The resulting clot starves the heart of oxygen and nutrient-rich blood, causing a heart attack and possibly death. Traditional diagnostic tools like treadmill stress tests only pick up major blockages in the blood vessels, but they don’t alert doctors to this type of impending catastrophe. That’s because the vast majority of heart attacks occur in people whose blood vessels are narrowed only slightly by cholesterol-laden plaque. “We can’t detect these mild narrowings, which are almost exclusively responsible for heart attacks,” says Dr. Eric Topol, director of the Scripps Translational Science Institute in La Jolla, California. But Topol and a team of researchers now think they’ve found a way to determine which patients are only days or weeks away from a heart attack.

Weight loss key is habits, not willpower, says Weight Watchers chiefWhat helped David Kirchhoff, president and CEO of Weight Watchers International, shed 38 pounds, start exercising and eat healthy breakfasts? Of course, you’d expect a CEO to toot the horn of his company. He did at TEDMED, a conference about medical innovations and ideas. But he also stressed that the essential factor that shaped his metamorphosis - from an overweight 33-year-old needing Lipitor to a fit man who exercises - was the habits he formed. FULL POST
