Research has demonstrated that the human being tends to couple body movements and external, acoustic stimuli (metronome or music). This effect is called auditory-motor synchronization. In addition, motivational music possesses characteristics which distract from feelings like fatigue and exertion. Combining these two factors may enhance the sports performance to a greater degree. Therefore, the purpose of this study was to examine 1) the contrast between the influence of no auditory stimulus and accelerated auditory stimuli (by 2% of the runners' original cadence, as this is the maximum of spontaneous increase) on running performance and 2) the influence of listening to music compared to listening to a metronome on running performance. In this regard, twenty-eight sport science students (15 females, 13 males) were asked to perform two Cooper tests each. After run 1 (no auditory signal), the sample was divided into two groups. In run 2, which took place on a different day, one group listened to music while running, whereas the other group was stimulated by the sound of a metronome. During the test, distance (m) and average heart rate (bpm) were measured. The results showed that 75% of all athletes achieved a greater distance under the influence of an acoustic stimulus. Thereby, the running distance changed significantly (p = 0.001) by using an acoustic stimulus: +61 m (SD +/- 100) or 2.1% (SD +/- 3.6). In group 1 (music), the performance improved up to + 3.8% (SD +/- 3.3), a significant difference compared to group 2 (metronome) (p = 0.014), in which no notable change in average heart rate was found. This means that if the tempo of the acoustic stimulus was adapted to the accelerated cadence of an athlete (maximum of spontaneous tempo adaption: 2%), improved distances due to the synchronization effect could be achieved. Furthermore, in combination with the motivating qualities of music, improved effects in sport performances could be created.
