Former Real Madrid defender Fernando Hierro is at the helm of a wearable tech start-up which is seeking to improve people’s health with intelligent clothing.

Hierro, who managed Spain at the World Cup following the sacking of Julen Lopetegui two days before the tournament started, is a founding partner and investor in Bionox.

The Andalusian start-up uses 1960s NASA technology in the design of ‘Ekatom’ garments which are beneficial to the health of the wearer.

The tissues it develops are based on FIR (far infrared) technology and are said to improve blood circulation and oxygenation, assisting muscle recovery.

This could have benefits for both medical treatment and sports performance.

"After developing the technology, achieving the approval of patents and closing the distribution agreements, Bionox are ready to go on the market," said Hierro.

There are agreements in place for 30 countries, according to the company.

Its president Julio Alvarez says the effects are "clinically proven and validated" and that they have "immediate effects on muscle tone and balance".
