Full Description: Dr. Klaus Bartonietz has called Neeraj Chopra’s gold-medal winning performance in men’s javelin throw at the Tokyo Olympics a “great” achievement. Bartonietz, the biomechanics expert under whom Neeraj Chopra trained for Tokyo 2020, said that the 23-year old Indian had recovered after having surgery on his throwing arm and then went all the way at the Olympics. Klaus Bartonietz, who coached India’s Neeraj Chopra to the men’s javelin throw gold medal at the Tokyo Olympics, has a technical take on why no athlete was able to throw even close to the 90-metre mark in the Tokyo 2020 final.
