sport specs SWIMMING
The history
Modern competitive swimming dates back to the 1896 Olympics when swimmers swam in a port in Athens, Greece, says Clark Campbell, head coach of women's swimming at KU.
The workout
Swimming can be a good compliment to an overall
fitness plan, Campbell says. Because it's an aerobic sport, swimming should be done for at least 20 to 30 minutes. For a more mentally stimulating workout, rest for 10 to 20 seconds every 25, 50 or 75 yards, a method known as interval training.

A workout utilizing all four strokes — freestyle, backstroke, breaststroke and butterfly — trains all muscle groups. Swimming for an hour can burn up to 1,000 calories Campbell says.
The alternatives
For the non-swimmer, there are other aerobic activities that can be done in the water. Grab a kickboard — a tombstone-shaped piece of floating foam — hold it with your arms stretched out in front and kick away. Not only does using a kickboard keep your head out of the water, but if done for at least 20 to 30 minutes the exercise works your legs and cardiovascular system. Interval training can also be done with
a kickboard.
Aqua jogging is a great way for people who like to run to get in the water. Use a flotation device to stabilize yourself while you mimic the motion of running in water that is too deep to stand in.
If you don't know how to swim, find someone to teach you, Campbell says. Also, keep your expectations within reach. Interval swimming is a good way to accomplish your goals without getting too tired. Lawrence Indoor Aquatic Center, 4706 Overland Dr., offers swimming lessons for adults. For more information, visit their Web site at www.ci.lawrence.ks.us/lprd/aquatics/iac.world.

DRINK BLACK TEA TO HELP PREVENT CAVITIES AND BAD BREATH
Though nothing can replace proper tooth-brushing, drinking black tea on a regular basis can help prevent cavities and gum disease, says Christine Wu, professor of periodontics and associate dean of research at the University of Illinois-Chicago College of Dentistry.
Wu and other researchers found that black tea infusions and extracts affect the growth of oral bacteria associated with cavities, gum disease and bad breath. Black tea leaves contain fluoride, which inhibits the growth of bacteria in the mouth, she says.
In Wu's study, research volunteers rinsed their mouths 10 times a day with black tea for a week
and 10 times a day with water for a week. The outcome showed that rinsing with black tea decreased the amount of plaque on participants' teeth.
So if you can't brush after meals, try sipping on a cup of black tea after you eat to rid your mouth of cavity- and bad breath-causing bacteria.
