Respiratory Muscle Training Methods for Improving the Lung Capacity of Professional Vocalists and Wind Instrumentists

". Introduction. Various muscle groups are involved in pulmonary ventilation, which play an essential role in maintaining proper breathing, their development being aimed at improving the physical, psychological and qualitative performance of the performance of professional singers and blowers in instruments. Objectives: The objectives of the training of the respiratory muscles are aimed at improving dyspnea, toning the respiratory muscles, increasing the efficiency of the respiratory muscles, increasing the volumes of air mobilized, decreasing the fan labor, controlling and coordinating the respiratory rhythm. Methods: The study subjects were 9 young musicians, students at the Conservatory in the singing and wind instruments sections, who performed workouts with a threshold device (POWERBreathe Inspirational Muscle Training IMT), five days a week, twice a day, for 6 weeks. Subjects performed spirometry tests VC, FVC, FEV1, FEV1/FVC, VF, FEV6 at each beginning and end of the meeting, the data collected were processed by interpreting the results of lung function and flow measurements. Results: The results obtained from the spirometry tests show us statistically significant differences between the initial (IT) and the final (IT) test. Thus, at the first sit, with the device adjusted to max.15% PI/PE (inspiratory – expiratory pressure), the average of the VC values, FVC, FEV1, VF, FEV6 (5.72 – 5.84l, l/s) increased by 2%, and at the end of the second session, with the device set to min.40-60% PI/PE, the average lung function values (5.72 – 6.14l, l/s) increased by 9.8%. Conclusions: This experiment can demonstrate that the acute effect of training with a breathing device (threshold) results in a significant increase in the use of flow during singing and blowing, leading to a sound with a higher acute sound and more activity."
