About Me  | Most Recent Posts BAT SELECTOR AND SWING WEIGHTPosted Feb-28-08 18:20:03 PST Bat SelectorBat speed, not bat size nor weight, drives the ball. Bat speed is affected by a number of variables including bat length, bat weight, bat Moment of Inertia (MOI) which is often referred to as swing weight or balance point, which are affected by barrel length. Note, a high MOI bat with a given bat weight on a higher swing weight than a lower MOI bat with a heavier bat weight. MOI is more meaningful than bat weight.
Choose your bat based on your physical strength, comfort level and your hand size. The stronger you are the bigger and longer the bat you can handle. NEVER use a bat that feels too heavy or is weighted too much at the end to be comfortable. In addition to weight of the bat, the balance of the bat or swing weight, often referred to as the Moment of Inertia (MOI) governs how a bat feels and is actually a more meaningful measure of how well it will swing for you. For example, a heavier balanced bat will feel lighter and swing faster than a lighter, end loaded bat. See attached paper [more] about how bat weight, inertia and swing speed are related. As a general rule, most players can hit a ball further with lighter (really low MOI) bats. It is only the biggest homerun hitters, who can hit the ball further with a heavier (really higher MOI) bats. Also, lighter bats provide more bat control during the swing phase. Everyone is different when it comes to sizing up for a bat. Use the tables above references only, remembering that there can be other factors that can affect a player’s bat length and weight. Another important factor in selecting a bat is the Barrel Length. In general, a longer barrel length increases the potential hitting surface and will directly increase good bat and ball contacts and hence batting average. To put it in perspective, the difference between a .281 and .312 hitter (and a Big League million dollar contract and trip to the Hall of Fame) is only one extra hit in 32 at bats. A longer barrel will get you on base more! WE’VE GOT BAT SELECTION DOWN TO A SCIENCE.Combat® Swingweights makes selecting the right bat much easier. It’s an exclusive new system based primarily on the fact that different players have different swings, and it’s the first of its kind to allow individual players to optimize their own performance and play.When measured by hit distance, batting performance relates directly to bat speed, bat weight, and weight distribution within the bat. The faster the swing, the further the hit distance, the higher the performance. Likewise, the heavier the bat with a fixed swing speed, the longer the hit distance, the higher the bat performance. Only the Combat® Swingweights system recognizes that bat swing speed is determined by two things: the bat’s center-of-mass and the bat’s moment-of-inertia (MOI). Our wide selection of Combat® Swingweights makes Combat the only company that can provide hitters with optimal individual performance. In general, bigger long distance hitters prefer higher Combat® Swingweights bats while smaller, finesse players prefer lower Combat® Swingweights bats. WHY COMPOSITE BATS !Posted Feb-28-08 18:17:34 PST Why CompositesCompared to aluminum, wood, and other materials used to make bats, composite materials (carbon, glass and Kevlar fibers embedded in a plastic resin) are lighter, stiffer and stronger. Of most importance, unlike bats made of other materials, composites are anisotropic which means bats can be designed to have different stiffnesses and strengths in different directions. The anisotropic property of composite materials allows Combat bat designers the opportunity to increase stiffness along the handle (reducing vibrations and reducing sting) and to decrease stiffness along the barrel (increasing “trampoline” effect and thus improving bat performance), resulting in Combat all composite bats with optimal performance and feel. Further, composite bats can be designed for a wide selection of Combat® Swingweights Safety is always an important issue, especially at the children and youth levels. The key to reducing the injuries in the game today is to create safer procedures and insist on protective equipment. Statistically speaking, Baseball and Softball are two of the safest sports played today. Unlike bats of other materials, composite bats have the unique ability to be designed and re-designed to meet specific and changing industry standards.
The most important mechanical properties of a baseball bat are: mass, center of gravity, moment of inertia, coefficient of restitution, vibrational properties, stiffness, strength, center of percussion, and maximum power point location. These properties can be engineered through numerous bat designs using various fiber and resin combinations, fiber orientations, and other factors [more]. During the extremely short swing phase, the most important bat performance characteristics are: maximum bat velocity, positional control, and longitudinal bending. These characteristics are controlled by mass, center of gravity, moment of inertia and longitudinal stiffness. The contact phase consists of a violent, even more extremely short duration, collision involving surprisingly high impact forces, which generate multi vibrational longitudinal and hoop vibrational frequencies. During the collision phase, the most important bat characteristics are: barrel trampoline effect which determines bat performance (hit distance), durability, sweetspot size, sound, feel and sting. These characteristics are controlled by coefficient of restitution, vibrational properties, stiffness, strength, center of percussion, and maximum power point location [more] In summary, designing an optimal baseball bat is a very challenging technical task, which is far from fully understood, and much less accomplished, in the industry. Further, wood and aluminum material characteristics severely limit, in fact make impossible, designing the optimal bat. Without doubt, composite bats in all segments will be the "Bats of the Future¨.COMPOSITE BAT PERFORMANCELITTLE LEAGUE BATS!!Posted Feb-22-08 18:28:10 PST LITTLE LEAGUE NEWS SOUTH WILLIAMSPORT, Pa. The Combat B1 Da Bomb was the bat of choice at the Little League World Series and resulted in a walk off homerun to right field in the bottom of the eighth inning to defeat Tokyo, Japan 3-2. The Japanese team was also swinging Combats starting in the International final where they hit three homeruns, all with the B1, including the game winning bomb. Japan bought their B1's mid-way through the tournament from the Canadian and Venezuelan teams. The winners were the Southeast team out of Warner Robins, GA (7 out of the starting 9 were swinging the Combat B1 Da Bomb). They won the championship game over Japan (3-2) in the 8th inning on a 225ft homerun over the right field fence. On the road to the Little League series, the GA team scored 101 runs and hit 47 homeruns in 13 games. One being a 300ft bomb in the Southeast final game. The Southwest team out of Lubbock, Texas came in 3rd place beating the Carribean team. Their big hitter went into the game with 3 homeruns with his Combat B1. The Southwest team all used Combat B1s. The Venezuela team beat the Netherlands 21-2 on 5 homeruns with Combat B1 Da Bombs and they scored 36 runs in the Little League World Series The West team's top three hitters out of Arizona, also swung Combats. The rest is History!
THE REASON COMBAT BATS ARE BETTER FOR YOUR LITTLE LEAGUER IS THAT THEY ARE 100% COMPOPSITE AND THEY HAVE A BALANCED HANDLE WEIGHT WITH LIGHT BAT RATIOS!! ITS ALL ABOUT BAT SPEED THESE DAYS!! |
