Sound stimulation and strength performance

Become a Patron!

Summary of an article testing the influence of auditory stimulus (sounds) on bench press performance in lifters.

Who

18 (6 females, 12 males) lifters aged on average 26.4±8.2 years with at least 4 years of experience (Italy).

Sound stimulation

  • initial countdown
  • low-intensity sound (60db) - down phase of the lift
  • high-intensity sound (95db) - pressing phase

No stimulation

  • no sound stimulation provided

Design

Cross-over study (counterbalance sequence of testing, no randomization)

Outcome measures/tests

  • power performance during 1 rep bench press at 90% of the 1 repetion maximum via Sensorize FreePower Training

Main results

Sound stimulation and strength performance - infographic

  • The best (highest) power output trials did not differ between sound-stimulated and no-sound groups.
  • Average power output differed between groups however. When the athlete performed bench press (at 90% of 1RM) with sound stimulation, they performed on average better (higher power output) than without sound stimulation.

Take home message

For a clinician & coach
Sound stimulation did not change the peak power performance during a bench press (90% of 1RM), but allowed for improvement in mean strength and variability reduction in performance.
For a parent
Sound stimulation allowed for better consistency in strength performance.
For an athlete
Sound stimulation allowed for better consistency in strength performance.
