テニスラケットの科学(76) 　腕系の障害、ラケットのリコール問題、米国消費者製品安全委員会(5)：Xenecore Answers the Arm Injury Epidemic Apr 20, 2016 | By New York Tennis Magazine Staff

“According to the International Tennis Federation (ITF), half of all tennis players will suffer from tennis elbow. Thirty-four of the top 40 ATP and WTA men and women have been sidelined recently from shoulder, wrist and elbow injury or surgery

In the past 30 years, more than 150 million players have suffered an arm injury, according to Mark Kovacs, former USTA sports science director. ”

“In the abstract “Prediction of Impact Shock Vibrations at Tennis Player’s Wrist,” the authors concluded that shock vibration is higher in super lightweight rackets. This is why Xenecore developed its revolutionary 114-square inch seven ounce super control racket which could become the next dominant form in the industry.”

“Based on Federal Consumer Safety Product Commission Recall regulations, all conventional hollow empty rackets are technically illegal because of the high likelihood of injury as they transmit well over 100 pounds of force and shock significantly longer than 0.2 seconds at impact.”

“Xenecore technology was developed to cure this arm injury epidemic.
