JACKSONVILLE, Fla. -

New rules now in place in at Georgia high schools will affect every summer football practice.

The policies implemented by the Georgia High School Association are designed to combat heat related deaths following the deaths of two high school players last August.

A startling 70 percent of all high school students showing up for football practice are already dehydrated before they even reach the field.

There are statistics from a new study that are leading to sweeping statewide changes in Georgia regarding the start time of sports practices, the number of practices, and the number of necessary breaks.

"They found that in the south and especially the southeastern part of the state, that we have more vulnerability," said Ralph Swearengin with GHSA. "People used to laugh and joke about the difference between dry heat and wet heat. Even though places like Texas and other places have high heat, they don't have quite the same high humidity,"

Swearengin said the rules model the NCAA'S.

The rules are putting a ban on three-a-day practices all together.

The first five days of practice are helmet only so football athlete's bodies can get used to the heat.

The new rules also state that two-a-day practices can't occur two days in a row and two-a-day practices can't exceed five hours in just one day.

"Especially with our athletes that are wearing protective equipment. A lot of that is insulating equipment and take our football players for example, they wear helmets on their heads, shoulder pads, sometimes multiple layers," Bob Sefick with Jacksonville Sports Medicine said. Some of these big guys feel like it's appropriate that they lose weight to tone up."

Sefcik said the state of Florida is considering similar safety measures. He said far too often overly competitive coaches push their players too far.

"Our biggest fear is always that one coach says that so and so is not following the rules, so I'm not going to follow the rules either, they see that as being a competitive advantage."
