(CNN) — Inspirational music has long served to focus the mind of some of the world’s greatest sporting stars.

Retired swimming champion Michael Phelps swore by the grizzly bark of rapper DMX, while former England footballer Stuart Pearce was known to crank out the snarling punk of the Sex Pistols.

For giant judo champion Teddy Riner, however, the motivational music of choice is something altogether more sensitive.

“The moments before the fight, I put my headphones on to enter into the zone,” Riner told CNN’s Human to Hero series.
