Answer
For Olymians, I found this:
Ten equally spaced wooden barriers stand between the world class hurdler and the finish line. They may hit the hurdles repeatedly, and many do. Although they are not penalized by officials, hitting the hurdles is not a good idea for several reasons. It hurts, slows the runner down and occasionally throws a runner's rhythm off and causes a crash.
The 110m hurdles for men and 100m hurdles are for women known as sprint hurdles as opposed to the 400m hurdles events which are sometimes called the âintermediate hurdles.â
The 110m hurdles are 1.07m high and placed 9.14m apart while the womenâs sprint hurdles are .84m high and 8.5m apart. They can be lowered for use in the 400m distance to .91m in the menâs event and .76m high for the women. Hurdles in the 400m hurdles races are placed 35m apart and the same location for both men and women.
Lane assignments are critical, as they are in sprints. Itâs advantageous to run in the middle lanes with competitors on either side. Some hurdlers, however, are so talented they can win from any lane. Xiang Liu of China, the reigning Olympic champion, won the 2007 IAAF World Championships in Osaka from lane 9 in an excellent time of 12.95 seconds.
The starter in all hurdles races will use the standard âOn Your Marksâ and âSetâ commands before firing the gun. Any athlete who leaves the starting blocks before the gun or faster than the allowable reaction time of 0.100 seconds is judged to have committed a false start. The first false start is charged to the entire field. Any athlete who false starts subsequently is disqualified.
Staying in their lanes
In the one lap event, the hurdlers will lead with their left legs which helps keep them from going out of their lanes. Because they run the entire race in lanes the hurdles are staggered so that each athlete runs the same distance to the first hurdle. The trick to see who is leading the race is to watch who reaches their respective barriers first.
The 400m hurdlers are also very good 400m flat racers. Kerron Clement of the United States, who won the 2007 world championships in a time of 47.61 seconds, beat Michael Johnsonâs world indoor 400m record three years ago. His time was 44.57 seconds.
Hurdlers will run heats and semi-finals before racing in the final.

This is a patent for an adjustable one, kinda neat.

What should you avoid if you're pregnant and why?
Just anoth
Hi there! So I'm doing a project. I'm creating a guide for pregnant women. What should they stay away from? What should they, er, not stay away from?
I'm not just talking food or drink-wise here. I mean any actions in general.
I figured Y!A was the perfect place to ask this. Real advice from real people, you know?
Answer
⢠Amusement park rides: Waterslides and other rides at amusement parks are a no-no, since a forceful landing or sudden start or stop could harm your baby
⢠Bicycling: Cycling isn't a good idea for newbies, but experienced riders may be able to continue until their second trimester, when a shifting center of gravity affects balance and can make cycling dangerous
⢠Contact sports: Soccer, basketball, and hockey put you at a high risk of injury from a ball or puck, a collision with another player, or a fall during play
⢠Downhill skiing: ACOG advises against downhill skiing anytime during pregnancy because of the risk of serious injuries and hard falls. If you choose to ski, stick to gentle slopes and be aware that you may have problems with balance as your belly expands. A safer choice is cross-country skiing, which is also much better for building cardiovascular fitness. Avoid skiing at altitudes above 6,000 feet, where there's less oxygen for you and your baby
⢠Gymnastics: Same risk of falling and increased chance of trauma to your abdomen
⢠Horseback riding: Even if you're a good rider, it's not worth risking a fall
⢠Post-sport tubs and saunas: Soaking in hot tubs and Jacuzzis or sitting in a sauna can be dangerous to your developing baby because overheating has been linked to birth defects
⢠Running: If you weren't a runner before you got pregnant, now's not the time to take it up. Otherwise, it's fine in moderation. From your second trimester on, when the risk of falling increases, you should run with caution. As with all forms of exercise, avoid becoming overheated, and drink plenty of water to replace fluids lost through sweating
⢠Scuba diving: This is an absolute no. As you surface, air bubbles can form in your bloodstream, which can be very dangerous for both you and your growing baby.
⢠Snowboarding: Same risk of falling and increased chance of trauma to your abdomen
⢠Surfing: Same risk of falling and increased chance of trauma to your abdomen.
⢠Tennis: A moderately paced game of tennis is okay if you played before you became pregnant. But you may have problems with balance and sudden stops, so watch your step. Most women find that it's hard to keep up their game as their bellies get bigger in the second and third trimesters
⢠Waterskiing: Another activity that puts you at risk for falling and increases the chance of trauma to your abdomen
⢠Amusement park rides: Waterslides and other rides at amusement parks are a no-no, since a forceful landing or sudden start or stop could harm your baby
