Reducing The Occurrence of Choking under Pressure through Use of Wearable Grasping Material Incorporated into Sportswear
【Supercategory：7. DESCENTE SPORTS SCIENCE Subcategory：7.42 Vol.42】
ABSTRACT
Previous studies have reported that squeezing a soft ball with the left hand immediately before an important movement may prevent choking under pressureduring games. Instead of squeezing a ball, we sought to identify an alternate material that could be attached to a uniform that an athlete can easily squeeze even during sporting games. In Study 1 we recorded electroencephalograms （EEGs） after squeezing three different materials. A fast Fourier transform （FFT） analysis showed the lowest alpha asymmetry score （ AAS） for polyethylene foam. In Study 2, we asked tennis players to squeeze the polyethylene foam immediately before the execution of a second-serve task in a pressure situation. Participants exhibited higher somatic anxiety in the pressure test, and showed improved scores after squeezing the material; but thisresult did not reach statistical significance. Lastly, we created a prototype sports shirt, in which the polyethylene foam is embedded in the left side.
