Vocal performance capability and musical diversity are pivotal features of success for classical singers. Both are essentially influenced by a superbly-balanced breath, and particularly by the singer’s muscular system and the coordination thereof. The present study examined the influence of a targeted mini-trampoline training upon breath support and breath management.

Materials and Methods

This explorative, 2:1 randomized controlled trial included 20 professional classical singers (male: 11: male alto: 1, tenor: 5, baritone/bass: 5; female: 9: soprano: 5, mezzosoprano/alto: 4) between September 2019 and June 2020. The intervention group (n=13) received a targeted mini-trampoline training over the course of 36 weeks (6 workouts of 42 days each), while the control group continued their singing work “as usual” in order to maintain or expand the existing standard of performance. At four points within the study (before beginning the training, after 12, 24 and 36 weeks), several performance levels were measured, including forced vital capacity, peak expiratory and inspiratory flow, forced expiratory and inspiratory volume in one second, panting rate at a stable frequency, the vocal range and maximum phonation time in relation to volume and pitch, with the latter depending upon voice genre.


The panting rate at a stable frequency as well as the maximum phonation time, were significantly longer (p<0.05) in the intervention group (=targeted mini-trampoline training); the longer the training was continued, the larger this difference became. Differences in further capacity levels among the two research groups were either nonexistent or insignificant. Furthermore, no correlation between forced vital capacity and maximum phonation time could be found.


The performance capacity of professional classical singers based on breath coordination seems to allow itself to be improved far more by targeted mini-trampoline training than trough singing work “as usual”.
