Re: El Puma's strength conditioning thread
Perform Better's Super Vertical Leaper safely develops explosive power, balance, and acceleration, according to the company. And the Sled Dawg II (for use with 2-inch Olympic weight plates) enables an individual to resistance train solo for improved strength and power in running starts.
Bruno Pauletto, president of Power Systems, Inc., is an expert regarding ballistic training. As the former strength and conditioning coach at the University of Tennessee, he implemented ballistic movements into the Vols' sports programs.
"Ballistic training bridges the gap needed to improve athletic. performance by providing functional strength," says Pauletto. "If a person just does weights, he is missing out on a very strong component that translates onto the field.

"If you want to jump higher for a rebound or make a better block or tackle in football, ballistic training is a real benefit. It's much more closer to the actual movements that are done on the field, court, or baseball diamond."
"Ballistic training enables the athlete to initiate a maximum amount of muscle fibers to produce a maximum amount of power in a short period of time," says George Morrison, COO and designer of the Xvest, which relies on "overloading" the body with properly positioned weights to provide an extreme work-out and produce dynamic respiratory resistance.
Designed for serious athletes seeking to improve their event-specific strength, the Xvest tricks the body, brain, and muscles into believing they have gained extra weight. When the vest is removed, the body functions and reacts as if the weight (available in 20 and 40 pound models in addition to a customized version) is still there. This produces increased power, endurance, and speed.
"The difference between the Xvest and every other vest out there is the ability to adjust the length of vest to fit the proper torso," says Morrison. "So we don't really disturb the center of gravity. Secondly, the Xvest doesn't restrict range of motion. Therefore we don't really change the biomechanics of any type of movement."
"You don't want to retard the biomechanics by more than 10 percent," Morrison added. "Otherwise you are retraining the biomechanics. You are disturbing the kinetic chain of the biomechanics."
The Xvest, which is the vest of choice of the U.S. Ski Team, the Super Bowl champion Tampa Buccaneers, and many other professional and college teams, is ideal for any sport and can he used for both ballistic and plyometric training and in or out of water.
While the Xvest has become popular on the scholastic level, Morrison cautions prebuscent or slightly older children from going the ballistic route.
Strike up the band
For more than 20 years, Jump Stretch, Inc. has promoted the use of heavy-duty rubber bands for alternative strength training.
"I was brought up during the Hank Strain era where you put as much weight on the kid as you could and made him as strong as you can," says Dick Hartzell, president and owner of Jump Stretch. "But there is only so much you could do with a 150-pound kid. Then I came up with the idea that strength training, or some portion of it, should be done as fast as possible with resistance."
