British javelin record-holder Goldie Sayers has appointed Dan Pfaff as her new coach ahead of next year's Olympics Games in Rio de Janeiro.
Over the last three years Sayers has been plagued by a variety of injuries, including one to her elbow that hampered her chances of winning a medal at London 2012.
However, the 33-year-old has insisted that Pfaff has the knowledge to keep her free from fitness concerns going forward.
"I see him as the best person in the world to keep me healthy. He is a master of body alignment and making sure everything is moving in the right direction," she told BBC Sport.
"Dan's very good at looking at mechanics. If the body isn't set up from an alignment perspective and there's tightness higher up the chain, he always looks at every little detail from when you start warming up to when you start the session.
"It takes a lot of the responsibility off me and means I can just get on and train and have to not worry about how everything's set up."
Pfaff has previously worked with a host of athletes, including British long jumper Greg Rutherford.
