Sugar water can help increase self-control, says study

By Nadine Bells | Shine On – Tue, Nov 13, 2012

If you're struggling with self-control, a quick gargle of lemonade — made with real sugar — might boost your resolve, new research suggests.

Researchers from the University of Georgia recently published their findings in the journal Psychological Science.

Fifty-one students took part in the study, each perform forming two self-control-testing tasks.

"The first task, which previous research has shown to deplete self-control, was tediously crossing out all the Es on a page from a statistics book. Then, participants performed what is known as the Stroop task where they were asked to identify the colour of various words flashed on a screen, which spell out the names of other colours," Forbes explains.

Before performing the Stroop test, half of the students rinsed their mouths with sugar-sweetened lemonade. The other half swished Splenda-sweetened lemonade. The researchers found that the students who rinsed with the sugary drink were faster at responding to the Stroop test than those who rinsed with the artificial sweetener.

Why the better performance? Researchers believe glucose — even when simply touching the tongue — triggers the brain's motivational centres.

"Researchers used to think you had to drink the glucose and get it into your body to give you the energy to (have) self control," says UGA psychology professor Leonard Martin, co-author of the study. "After this trial, it seems that glucose stimulates the simple carbohydrate sensors on the tongue. This, in turn, signals the motivational centres of the brain where our self-related goals are represented. These signals tell your body to pay attention."

Martin adds that glucose doesn't just boost energy levels, it boosts personal investment in current tasks.

"The glucose seems to be good at getting you to stop an automatic response such as reading the words in the Stroop task and to substitute the second harder one in its place such as saying the color the word is printed in," he says. "It can enhance emotive investment and self-relevant goals."

The study was small and will need further research, though Martin speculates that sugar water might help those trying to drop pounds or quit smoking.

In the meantime, curious individuals can always test the theory by gargling sugar water the next time they have to (begrudgingly) stay behind at work to get tedious work done.

The one exercise that women can't do

Women Can’t Do Pull Ups: It’s a Law of Physics

Don't worry, it's normal. Don't worry, it's normal. I love when science proves that I'm not a wimp. In a study performed by the University of Dayton, out of 17 women who specifically trained for three months to complete a single pull up, only 4 succeeded. "We honestly thought we could get everyone to do one," Paul Vanderburgh, a professor of exercise physiology at the University of Dayton, tells the New York Times."

In what sounds like a rather grueling regime, the women, all average weight and college-aged, pumped iron on an incline three days a week to gain muscle mass, and also did aerobic exercise to slim down. After 90 days, they were leaner and stronger: the average participant lowered her body fat by two percent and increased her upper body strength by 36 percent. Still, when it came time to do the dreaded pull up, most of the women failed.

Vanderburgh explains that women not only develop less muscle than men (whose body composition is fueled by testosterone), the proportion of women's limbs makes performing a pull up tough. "We're a combination of levers; that's how we move…" he explains, "I look at a volleyball player and wouldn't expect her to be able to do a pull-up, but I know she's fit."

The Marines don't require female recruits to do pull ups, but the Presidential Fitness Test says that teenage girls should be able to execute one pull up to score within the 50 th percentile-two for girls under 14. While I'm awe of super women who can crank out a few pull ups, for the rest of us, maybe it's time to lower the bar.

Admin: Admin percaya ramai wanita-wanita di luar sana yang tidak tahu berhubung dengan fakta ini. Rasanya guru-guru dan jurulatih-jurulatih sukan juga tidak mengambil serius hal ini. Selamat bersenam...
