Olympic wrestling hopeful Risako Kawai says she has chosen to focus on what she can control rather than fussing over what she has been denied by isolation necessitated by the coronavirus pandemic.

With the outbreak affecting everyone's lives, including those of athletes, Kawai has been exercising her mind, taking in knowledge that will keep her brain sharp and make her a better wrestler.

"I can't do, but I can watch," she said, explaining how she has been spending time watching videos of her opponents, researching techniques and mentally rehearsing match scenarios.
