BackgroundMany trumpet players use breathing training devices in addition to their daily practice routine. Playing a brass instrument requires, besides many other skills, a controlled air stream to generate the necessary air pressures. On the trumpet, high intraoral pressures are needed, especially during high and loud notes. Therefore, it is not uncommon in trumpet pedagogy to teach that the use of breathing training devices enhances physical strength so that the required pressures can be produced with less effort. However, to date, no systematic assessment of the use of breathing training devices among trumpet players exists and their effect on playing performance is still unclear.MethodsIn this a pre-post, within-subject repeated measure study, we investigated the influence of a 5-week expiratory muscle strength training (EMST) upon trumpet performance. Twenty-four male professional trumpet players were allocated to either a control or intervention group. The intervention group (n =13) trained with an EMST device against a set resistance of 55% of their maximum expiratory pressure (MEP) for 5 weeks on 5 days per week. The control group (n =11) did no intervention. All participants underwent the same measures (MEP and rate of perceived exertion [RPE]) and played the same tasks (maximum long note, maximum high note, maximum dynamics and phrasing in high register) prior to and after the 5 weeks.ResultsAfter EMST, MEP increased significantly (13%, p = 0.049) in the intervention group, whereas no significant change was found in the control group. Performance parameters did not change in either of the groups, also after EMST. Despite the increase in MEP, we found no evidence that EMST has an influence on trumpet performance.ConclusionWe conclude that EMST seems unnecessary for the enhancement of trumpet playing, at least in a population of male professionals who already demonstrate excellent respiratory condition and control.Copyright© 2023 by the author(s).
