This study was not very long. I'm thinking it lasted a little over a month.
I can't understand why this isn't great news for everyone with a kid playing the sport.

Thirtytwo IHSA schools submitted data on wood bats from spring 2007 baseball games, and 11 of the 32
reported data for games played both with wood and nonwood bats.
In the 412 games played by the 32 teams using wood bats, there were 368 broken bats, resulting in a batbreakage
rate of 28.3 per 1,000 atbats. If the bats were just used in games, this rate calculates to 23.49 broken bats per team for the entire season. Stated another way, a wood bat could be used for an average of 35.5 atbats before breakage.
The comparative research of teams using both kinds of bats during the season indicated an average of
8.77 hits per game in games with nonwood bats compared to 6.50 hits per game in games with wood bats. In addition, nonwood
bat games lasted 12.35 minutes longer (2:05 compared to 1:53). Although there were also more extrabase hits, atbats and runs scored in nonwood bat games, the lengthofgame and total hits categories were,according to Laudner, the only ones with statistically significant differences.
The participating schools reported five injuries in games with nonwood bats in a total of 4,682 atbats, compared with two injuries in games with wood bats in a total of 4,462 atbats; however, ISU researchers said, after analysis, these data show that there is no statistical difference in injury rates when using a nonwood bat compared to a wood bat.
Of the seven total injuries, only two caused the players to miss playing time, and neither of those involved a
bat. One player was hit in the face by a pitched ball and another sustained a blister on a finger. None of the injuries
from a batted ball required any player to lose playing time – in either the woodbat games or the nonwoodbat games.
The idea for the woodbat study came from the Illinois High School Association. “After an extensive search for wood vs. nonwood
bat usage, we concluded that there was no research available to answer our questions,” said Anthony Holman, assistant executive director of the IHSA. “So, we decided to commission our own study using high school teams and players to obtain some concrete data.
