The San Francisco Giants may be wearing headphones while they train, but they’re not listening to music. They are getting their brains “stimulated” to improve their batting, pitching, and catching.
The headphones are a new tool used by the Giants in hopes of enhancing player performance across the board. The team’s deal with the device’s maker, Halo Neuroscicnce, is the first public pact with a Major Baseball League team and a sign of how sci-fi technology is making inroads into pro sports.
The Giant’s use of the headphones, announced by Halo on Wednesday, comes just days before the start of the baseball season. The technology makes up an important part of the team’s training process, the startup said, along with the usual stretching, running, and weight lifting.
The theory is that low-level electric pulses, known as transcranial direct current stimulation, from the headphones stimulate a part of the brain known as the motor cortex, Halo Neuroscience CEO Daniel Chao told Fortune last year, long before the deal with the Giants was announced. That stimulation combined with physical training, can boost an athlete’s strength, “explosiveness,” and skill, he said at that time.
