Diver Dive

Why do the Olympic divers dive with flat hands when they hit the water? I'm surprised someone noticed. Many of the observed injuries to the upper extremities associated with entries are related to the flat hand entry technique that has been popularized during the past 25 years. Just before entry, the hands are brought together, the wrists are dorsiflexed, one hand is clasped over the other and the thumbs are interlocked with the palms facing the water. As the hands make contact with the water, the head is moved into line with the trunk, the arms squeeze the ears, and the hands push through the water, in effect "punching a hole in the surface". Upon breaking the surface of the water, the diver pulls the arms forward or to the side in the scapular plane in a swimming motion (the swim-out) to propel him through the water more rapidly. The flat hand entry creates a low pressure area immediately behind the hands, and the water that is pushed aside flows easily into this void instead of shooting to the surface. When executed perfectly, on the surface one observes a boiling effect but no splash, which sounds like a piece of paper being torn (a "rip" entry). So it's to minimize the splash and possible shoulder injury. Excellent question! Enjoy!

Having Fun Scuba Diving in Florida

Scuba diving is a popular outdoor hobby and every scuba diver who has a passion for diving will always be on the lookout for scuba diving areas anywhere in the world.

No less than seventy percent of the earth is made up of water so one can imagine the vast amount of water areas where scuba diving enthusiasts can go and enjoy diving.

A scuba diving hobby is especially suited for those who have the time and perhaps the extra money to go around the world looking for the best scuba diving spots. 

There are a lot of virgin waters all over the world that are good areas for scuba diving. Some of these areas have never been explored and discovered while some have remained a favorite scuba diving destination for most people all over the world.

One area that has become so popular among scuba divers because of its serenity and bountiful underwater resources is the Florida Keys in North America. Scuba divers wouldn't want to miss an opportunity to dive in the Florida Keys which consists of islands along Miami.

A diver who wants to try scuba diving in the Florida Keys can easily access the area from Miami. Hop in and enjoy a 45-minute ride and the diver is on his way to a great scuba diving trip in the Florida Keys. If he is unfamiliar with the area, he should stop by Key Largo and choose from a variety of operators doing the scuba route.

Florida Keys is a great area for scuba diving because there are numerous sites to choose from, both for the beginner to the advanced scuba divers. Beginners can go to Molasses Reef and feast their eyes on the healthiest coral reefs and schools of fishes in the area. Those who wish to do scuba diving along wreck sites can visit Benwood while the more advanced divers can go to the deeper diving sites in the area.

Advanced scuba divers should take note of the Spiegel grove and Duane, ships that were sunk for the enjoyment of scuba divers. Not only that. Scuba divers who want to get more training should visit Florida as it offers a variety of diving lessons for the hobbyists and the serious divers.

Diving is perhaps one of the best hobbies because a person gets to commune with underwater creatures at a closer range. The underwater scenes will always be heavenly especially for those who love the marine world. And all of these are present in Florida.
