Dr Klaus Bartonietz has spent decades decoding the science behind elite performance. The German biomechanics expert, who played a pivotal role in guiding Neeraj Chopra to Olympic gold at the Tokyo Games, believes that success in throwing events is not just about strength; it is about creating complete athletes capable of thriving under pressure.Now serving as a technical expert for the Inspire Institute of Sport’s (IIS) throws programme in Hisar, Bartonietz is focused on shaping India’s next generation of track and field stars. Having previously contributed to Chopra’s Diamond League triumph in 2022 and his World Championship gold the same year, the veteran coach brings both scientific depth and practical experience to Indian athletics.&nbsp;Reflecting on his journey, Bartonietz says his understanding of biomechanics has “dramatically increased” over the years, from early academic curiosity to hands-on coaching of elite athletes. “The goal was always to support athletes, not just do academic research. When you work closely with coaches, you know exactly what matters,” he explained in an exclusive conversation with WION.&nbsp;Rather than pointing to a specific technical flaw among young Indian throwers, Bartonietz identifies a broader developmental gap. “What I’m missing is a well-structured, multi-sided preparation. We want an athlete, not just a javelin thrower or discus thrower,” he says. According to him, athletes who lack exposure to multiple disciplines often struggle to adapt to new challenges, ultimately limiting their performance ceiling.&nbsp;Also Read: <a href="https://www.wionews.com/sports/t20-world-cup-2026-england-win-thriller-nepal-win-hearts-as-former-champions-kick-start-campaign-1770554892187">T20 World Cup 2026: England win thriller, Nepal win hearts as former champions kick start campaign</a><h2>What makes a world-class thrower?</h2>For Bartonietz, biomechanics is only part of the equation.
