Every acceleration, every lunge and every return that Carolina Marín makes on the court is the result of rigorous physical and mental preparation, but the badminton champion also relies on a secret tactic based on artificial intelligence, machine learning and big data.

The objective? To transpose Marín’s movements, and those of her rivals, into data to optimize performance, capitalize on opponents’ weaknesses, predict the trajectory of a game and to tailor training exercises.

“Everything is an ingredient brought together in a dish that is quite complicated to cook,” Fernando Rivas, Marín’s trainer and a key figure in the success of the Olympic gold medal winner, tells Efe in an interview.
