Actually it works !!! Some instructor try it in Australia with Crocodile

Swimming instructors at Casuarina swimming club in Darwin, Australia, have a unique way to help teach their young students to swim faster - by having a crocodile chase them during speed trials! The instructors use a six-foot saltwater crocodile with its jaws taped shut, but even with all those precautions, students still find the experience a tad intimidating. Yet this new teaching method seems to be working - the students have found that it helps shave seconds off their swimming time!
