High school baseball To reduce the burden on the pitcher Test to reduce the repulsive force of the metal bat February 17 18:13
The Takano Ren = Japan High School Baseball Federation, which is working to reduce the resilience of metal bats as a measure to reduce the burden on high school baseball pitchers, conducted a performance test of a prototype metal bat in Tokyo on the 17th.
In high school baseball, the performance of metal bats has improved the performance of metal bats, and the number of home runs in Koshien in the spring and summer is on the rise. Also came out.
In response to this, Takanoren decided to review the standards in September last year to reduce the repulsion of metal bats as part of measures to reduce the burden on pitchers.
On the 17th, a test of a prototype of a new bat with reduced repulsion was conducted in Tokyo, and a ball at 190 km / h was hit on the bat fixed to the instrument, and the rebound performance was calculated from the speed at which the ball bounced off .
The metal bat has a "trampoline effect", in which the surface is slightly dented the moment the ball hits, and then rebounds with a restoring force.
In reviewing this standard, it has been considered to reduce the diameter of the bat by 3 mm or increase the thickness of the metal to suppress the effect.
In the future, the Product Safety Association will set new standards for metal bats based on performance tests, etc., and Takanoren will introduce metal bats with reduced repulsion from next year.
"We would like to introduce a new standard metal bat as soon as possible to protect the safety of players," said Takano Ren's director, Kazuhiro Tanabe.
