Remember last year’s 4x100m relay race at the IAAF World Championships in London, when the Olympic champion and world record holder Usain Bolt tore his left hamstring in the final race of his career and had to exit the track via a wheelchair? Hamstring injuries are that bad and every sportsperson carries a risk of getting it injured at some point. They are the most common injury in sports which accounts for 37% of the muscular injuries observed in a sport worldwide.
