7 Fitness Rules You Should Break from yahoo.com
Old rule: Avoid exercising in the heat.
New rule: Acclimatize slowly and cool your neck.
A series of experiments shows that cooling the neck before working out in hot, humid weather can significantly boost athletic performance. Volunteers wearing ice-cold, strap-on neck collars could run faster on a treadmill in 87-degree heat than when they weren’t wearing the collars. You can get similar results by dipping a handkerchief in ice water and draping it around your neck.
Old rule: Drink before you’re thirsty.
New rule: Drink up, but avoid fluid overload.
For years, sports nutritionists recommended “drinking ahead of thirst” to avoid dehydration. However, recent studies show that slight dehydration doesn’t hurt athletic performance or health.,A study by the Sports Science Institute of South Africa compared runners who did three two-hour workouts, in which they either quaffed a sports beverage according to thirst (about 13 oz. per hour), at a moderate timed rate (about 4 oz. every 15 to 20 minutes) and at a high rate (about 10 oz every 15 to 20 minutes). There were no significant differences in core body temperature or finishing time.
Old rule: Cardio burns the most calories.
New rule: Weight training is a better fat-burner.
A recent University of Southern Maine study found that 30 minutes of weight training torches as many calories as running at a blistering six-minute-mile pace. Along with boosting strength and chiseling muscles, weight training revs up your metabolism for up to 36 hours. High-intensity training is another excellent fat-burner, with a recent review in Journal of Obesity reporting that it’s more effective than other forms of exercise for flattening the belly, while also improving aerobic fitness.
Old rule: Work out longer and faster to boost your health.
New rule: Aim for 30 to 60 minutes of moderate exercise daily.
A new study found that people who jogged 10 to 15 miles per week, at a pace of six or seven miles per hour, significantly outlived those who ran further and faster. The low-mileage group had 27 percent lower risk of death, compared to non-runners, while people who logged more than 25 miles weekly at higher speeds had no significant drop in mortality. The study analyzed the medical records of nearly 53,000 adults over an average of 15 years.
Old rule: Subtract your age from 220 to get your maximum heart rate.
New rule: Women should use 206 minus 88 percent of their age.
To burn fat and improve endurance, typically, your target heart rate should be 60 to 80 percent of your max. However, the traditional formula is based on research in men and can result in a max that’s too high for women, according to a study published in Circulation. The researchers developed the new gender-specific formula based on an analysis of about 6,000 healthy women ages 35 and older. And while the math is a little tricky, you only need to run the numbers once a year—on your birthday.
Old rule: Stretch before your workout to prevent injuries.
New rule: Do a 10-minute dynamic warm-up.
A study published in British Medical Journal found no scientific evidence to back up the notion that stretching before a workout reduces injuries or that stretching before and after prevents muscle soreness. Other studies show that static stretching can actually impair athletic performance, while dynamic warm-ups—such as pairing calisthenics (like squatting and lunging) with running drills—improve it. Dynamic warm-ups also reduce injuries, a 2006 study found.
Old rule: Prevent or treat overuse injuries with custom foot orthotics.
New rule: Cheaper prefab inserts are just as good.
Custom orthotics are a billion-dollar industry, but there’s little evidence that they deliver more benefit. A study of military recruits found no difference in rates of stress fractures, ankle sprains, or foot problems in those given custom orthotics versus those who wore prefabricated inserts.
8 Ways To Beat Bad Breath from womenshealth.com
Stay On Top Of Your Teeth. Brush twice a day and floss at least once daily to remove the plaque and bacteria that accumulates on your teeth and under your gumline. And be sure to visit your dentist twice a year for a checkup and professional cleaning.
Clean Your Tongue. The fleshy surface of the tongue is a prime breeding ground for harmful bacteria and accounts for a large percentage of halitosis cases; but most people neglect this crucial area when brushing. To dislodge the offending build-up take a regular soft bristle toothbrush and make a few gentle strokes down the tongue from back to front once a day.
Go Sugar-Free. Reaching for mints and gum can help mask that dragon breath but if you're using sugary brands you're actually adding to the problem. Bacteria in your mouth tend to ferment sugar, which leads to those very unpleasant odors. So stick with sugar-free solutions. And while you're at it, cutting down on sugar in the rest of your diet can go a long way in snuffing out those icky smells.
Wet Your Whistle. Your saliva contains vital protective enzymes that help kill bad bacteria, so a dry mouth can be contributing to your smelly situation. Staying hydrated will help stimulate the salivary glands and keep your mouth properly moisturized.
Pass the Bread. A low-carb, high protein diet may be the cause of that killer bad breath according to an analysis by the Physician's Committee for Responsible Medicine. The key to these diets is a fat-burning state known as ketosis when your body burns stored fats to use as fuel instead of the missing carbs. As the fat burns, chemicals called ketones accumulate in the body and are released in your breath.
Take a Tea Break. Drinking tea can do more than soothe your soul, according to findings presented at an annual meeting of the American Society for Microbiology. It can also help that halitosis. The research out of the University of Illinois at Chicago shows that polyphenols, chemical components found in black and green tea, can prevent the growth of the bacteria responsible for bad breath as well as the bacteria's production of putrid smelling compounds
Spice It Up. Cardamom, a sweet exotic spice often found in Indian cooking, has been known to contain antibacterial properties and has been used for ages as a natural breath freshener. The cardamom plant is high in a compound called cineole, a potent antiseptic that kills bacteria and alleviates bad breath. Chew on a few cardamom seeds as an alternative to mints and gum or try fennel seeds, another herbal remedy also known to work on bad breath.
Get a Physical. If you've been on top of your dental care, have tried all of the above and your breath could still peel the paint from the walls, it's time to ring up the doc. Chronic nasty breath can be a symptom of a variety of other underlying medical issues such as diabetes, severe sinus infections, post-nasal drip, GI disorders, or liver and kidney problems.
