We all know that exercise is good for the heart, but do you know how much to do and what benefits to expect? “A large number of epidemiological studies have…
“Want to lose weight? Then run, don’t walk,” reported U.S. News & World Report in the April 2013 issue.
When it comes to running vs. walking, the Lawrence Berkeley National Laboratory in California conducted a six year National Walkers’ and Runners’ Health Study. When they compared men and women who increased their walking or running, they found that running expended more energy than walking.
But people who choose to run may be different—they may be more physically fit, for example—than people who choose to walk.
Sitting for hours on end can hurt more than your back end, say two studies.
British researchers tracked 153 younger and 725 older adults who all had risk factors for diabetes. Each participant wore an accelerometer to measure how much time he or she spent sedentary or engaged in moderate-to-vigorous exercise (like running or brisk walking) for at least a week. The results helped researchers hone in on why sitting is bad for people who are at risk for health problems such as diabetes.
Does it matter if you walk slowly instead of briskly for exercise? Is 30 minutes a day of slow walking good enough, or are you better off walking for an hour?
It depends on what your goals are, says Robert Ross, an exercise physiologist at Queens University in Kingston, Ontario.
According to the International Continence Society (ICS), incontinence is the “involuntary loss of urine that is a social or hygienic problem and is objectively demonstrable.” Urinary incontinence is most commonly a result of bladder dysfunction, sphincter dysfunction, or a combination of both. An estimated 30 to 40 percent of middle-aged women and 50 percent of older women experience urinary leakage.
The problem is less common in men, but does increase with age. Even so, older men experience severe urinary incontinence at only about half the rate of women. Despite the prevalence of this health problem, it is still a “don’t ask, don’t tell” issue.
“In our study of nurses, less than 50 percent of the women who had incontinence reported it to their doctors,” says Mary Townsend, an epidemiologist at Brigham and Women’s Hospital in Boston.
It is a sensitive issue, for sure, but what is the cause of urinary incontinence? Leaks are more common in women who are older, heavier, or smokers, and in those who have had more children, diabetes, or a hysterectomy.
“Beverage of champions: Chocolate milk gets an Olympic-style makeover,” reported the Washington Post in January after ads featuring U.S. Olympic athletes began popping up during the Sochi winter games. Olympic athletes have access to the best in exercise regimens and health and nutrition advice. If they drink chocolate milk post workout, should you?
When it comes to recovering from intense exercise, this classic childhood beverage has taken the spotlight.
In some studies, drinking chocolate milk immediately after a strenuous workout is one of the best ways to recover quickly—better than sugary sports drinks like Gatorade. The milk’s naturally occurring sugar (lactose) is half glucose, its protein speeds up glycogen synthesis in the body, and its electrolytes (like potassium and, to a lesser extent, sodium) help you rehydrate.
Here’s how much exercise a 150-pound person would have to do to burn off the calories in some popular snacks.
Maybe you’d be better off with a peach or an orange (60 calories each) or a grande Skinny Latte (120 calories) instead.
Researchers assigned roughly 150 overweight, sedentary, middle-aged men and women with high LDL (“bad”) or low HDL (“good”) cholesterol to aerobic training, strength training, or both.
The aerobic training meant doing the equivalent of 19 kilometres a week at a vigorous pace on treadmills, elliptical trainers, or stationary bicycles. For strength training, participants did three sets of each of eight exercises, with eight to 12 repetitions per set, three days a week.
After eight months, those who did just strength training lost only subcutaneous (below-the-skin) abdominal fat.
