MUSIC AND STATE MODULATION

Synchronous and Asynchronous Effects of Music

Music influences sports performance through two main mechanisms: synchronous and asynchronous.

The synchronous effect occurs when the athlete adjusts his or her movements to the rhythm (tempo) of the music, which improves motor efficiency and endurance by acting as an external metronome.

The asynchronous effect refers to the use of music as background music to modulate mood or distract from fatigue, without necessarily moving to the beat.

An example of synchronous use would be an indoor cycling (spinning) class where participants pedal to the exact beat of a 140 BPM techno track.

This synchronization reduces perceived metabolic cost and increases group cohesion.

In contrast, a weightlifter who listens to heavy metal before a lift is using the asynchronous effect: he will not lift the weight to the beat of the drums, but uses the aggressiveness of the music to raise his arousal and motivation before the explosive effort.

Use for activation or recovery

Music selection should be strategic according to the physiological objective. For pre-competition activation, fast rhythms and empowering lyrics that increase heart rate and alertness are recommended.

For post-exertion recovery, slow, sedative music helps reduce cortisol levels and accelerate the nervous system's return to calm. Think of a swim team.

On the bus to the pool, they might listen to a collective high-energy playlist to "wake up" the nervous system.

However, immediately after the finish, in the cool-down zone, listening to classical or soft ambient (low-tempo) music would facilitate the lowering of pulsations and muscle relaxation, initiating the process of tissue regeneration more quickly than if they remained silent or listened to loud music.

The psychologist can help create these "soundtracks" for each phase of performance.
