  • An objective was to assess design and material options to produce a superior batting glove at impact loads typical in a major league baseball (MLB) game. Testing was done to compare performance at typical injury sites, including the dorsal area of the hand when hit by a pitched ball, and the hamate area from bat impacts. An objective was to conduct testing using an accurate physical model of the human hand with its bones and soft tissue. Further testing was conducted with accurate input loads through drop impact using equivalent energy to MLB level pitched balls, and equivalent speed/ mass of pitched balls using a ball cannon.
  • MLB major league baseball
  • EVOSHIELDTM batting hand shield which is a rectangular moldable gel to rigid rectangular pad encased in neoprene and adapted to fit across the distal half of the metacarpals without side extension.
  • Test Strategy A hand model was constructed using a purchased skeletal hand, and then built up with various substances to model soft tissues. The intent was to first use this as a drop-impact test using actual baseballs, to permit a dorsal (anterior) area pressure comparison. A ball cannon was used to shoot baseballs accurately at several dorsal areas of the hand model, to simulate loads from pitched baseballs, using impact speeds typical of the major league game. Impact locations were taken from several known injuries, and applied to the most injury-prone areas of the hand. This included the fourth and fifth metacarpals on the dorsal hand. The second strategy was to compare forces on the Hamate loads from the bat knob on the hamate, on the palmar ( posterior) side.
  • Drop Test Accurate Adult Hand - Model 2: Test fixture - The second drop test used the same structure as initial testing, but used a more accurate adult hand model.
  • the hand was mounted to mimic gripping a real bat with a baseball resting on top of the sample being tested.
  • a thin layer of neoprene was used to mimic skin and a single layer of SHOCKTEC® gel was placed on the palmar side to represent the tissue in the palm as well as the presence of grip tape on the bat (no actual tape was used).
  • FujiFilm was placed on the fourth and fifth metacarpals as these were deemed the most vulnerable.
  • SHOCKTEC ® Gel is a commercially available hybrid polyurethane elastomer impact gel that is very flexible and adhesive so nothing extra was required to secure it to substrates.
  • Polyurethane foams are also available. Polyurethane foams are thermoset materials polyurethane polymers that may be air frothed. An example is SHOCKTEC ® AIR2Gel. When force hits the polyurethane gels or foams the impact is dissipated throughout the entire material thus resulting in minimal relative force at the impact point. After impact the polyurethane gels or foams return to their original shape.
  • Hamate area Test Fixture A hamate model was constructed using a steel bolt ground to resemble the shape of the bone. This bolt was covered with a 0.093” thick piece of neoprene to represent the tissue between the hamate and the surface. To represent the impact load from a typical mis-hit ball (3 ft-lb of energy), a 1.375-pound weight was dropped from a height of 26 inches. A load cell was placed between the sample being tested and the neoprene sheet to provide an image of the force over the impact duration.
  • Table 3 shows the data from the hamate load cell drop test. Using the EVOSHIELD as a baseline we directly compared each of the other samples to it. These samples were chosen to be tested as they provided similar or better protection while minimizing the discomfort of added material while gripping a bat. Below Table 3 are waveforms generated by the load cell during each of the impacts. They have been cropped to more clearly show the profile of the impacts. [0095] Table 3
